Cooling and heat pump systems available in R22 models 2088 & 2588. 2 Installation of FDT (Cassette) Application Unit installation The unit is designed for most commercial applications, i.e. shops, offices, gyms, meeting rooms, bars, restaurants, etc. It should not be installed in an area contaminated by oil, chemicals, or an area with steam or excessive humidity, or hazardous substances, i.e. flammable gases, vapours, resins, thinners, petroleum, acids. Lift the unit into position, central within the opening, and secure with nuts and washers on the suspension bolts, adjusting unit height using the level gauge provided. Ensure pipe terminations are correctly positioned, facing in the right direction. Use a spirit level to ensure unit is horizontal. Do not install adjacent to equipment generating magnetic waves or high frequency signals, as the generated noise may cause equipment malfunction. Refrigerant piping Drain Unit location Select a suitable location within the room to allow optimum air distribution to all parts of the conditioned space. The minimum distance from a wall or obstruction is 1000mm. The unit should be located so as not to cause draft disturbance to a person located directly in the path of the air discharge. Level gauge Fix the level gauge in alignment with the face of the supply air grille. Adjust the suspension nuts so that the guage is level with lower surface of ceiling. 1000 or more Installation space Obstacle Unit Location avoiding obstruction Dimensions mm Dimension ‘A’ mm FDT 208 45-47 FDT 258 - 508 40-45 1000 or more Ceiling member Recommended floor to ceiling height minimum maximum 2250mm 3600mm Recommended minimum ceiling void space FDT 208 FDT 258, 308 FDT 408, 508 225mm 270mm 330mm Level gauge (insulation) Condensate piping The FDT cassette includes a condensate lift pump, capable of pumping upwards 700mm above the ceiling line. It is important to keep within this limit. See also space collar installation for restricted height ceiling voids The lift should be installed vertically from the drain outlet. If installed at an incline, this should not deviate more than 100mm from the vertical (see piping diagram). This is to prevent too much water being contained in the vertical lift, which would flood back to the unit and overflow when the power is switched off. Preparation for installation A pattern cardboard sheet is enclosed with the packing, indicating the ceiling opening size, and the required position of the hanging bolts. Check measurements with the drawings, and make opening. The pipe termination is of rigid pvc, 25mm o.d. A short length of flexible connection is provided in the installation kit, together with a circular clip, terminating in 25mm i.d. (32mm o.d.) connection. Fix suspension bolts (4 no. M8 or M10 – supplied by installer) into the building construction, in the required positions. The bolts and fixings must have a minimum resistive force of 50kg. The suspension bolts should be cut to length, to finish approximately 70mm above ceiling line. Please refer to page 23 Condensate Drain Installation & Recommendations. 3 Safety Warning: Refer to safety data on back cover of this manual Fascia panel fixing • Check the unit is level, using the level gauges provided. • Screw two of the fixing bolts into two diagonally opposed sockets. • RCD remote control installation (wired type) Please refer to page 8 for RCD installation instructions and customise settings. Locate the panel onto the bolts, and insert the two remaining bolts. Remote control (wireless infra-red type) The facia panel can be rotated on it’s locating screws to allow accurate alignment with the ceiling grid • The FDTN version of the 8 Series cassette systems is supplied with an infra-red controller. A wall mounted bracket is provided. For operational details, please refer to page 18. Fix the panel only in the position indicated in the packed instructions, i.e. with all four air outlets correctly aligned, otherwise there will be air leakage. Branch duct It is possible to deliver a proportion (20% max) of the conditioned air to a small adjacent area using a branch duct connection to the side of the FDT cassette unit. Fresh air intake The FDT cassette includes an aperture in one corner for the introduction of fresh air. A small knock out is provided in the corner section of the unit (in one position only). The position and dimensions are shown on the drawing below. The branch duct can be connected at positions on four sides of the unit. There are knock-out sections, allowing the installer to make an opening to suit the size of the connecting duct. The suggested size for the branch duct is 150mm dia. or similar. The fresh air inlet is on the suction side of the turbo fan, and will draw in a small quantity of fresh air, provided the inlet duct is not longer than 5 metres. The inlet duct should have a cross section area of at least 750mm2. Where a fan is used to provide a positive pressure for the branch duct, the air volume should not exceed 20% of the unit air volume. Where a fan is used to provide a small positive pressure for the fresh air intake, it is essential the volume of air does not exceed 10% of the air volume of the unit. Too much fresh air entering the unit will result in excessive noise. 3 Fresh air entry position Branch duct to adjacent room Branch duct - four positions Cassette Unit viewed from above 2 1 Fresh air inlet duct connection to corner of unit Condensate drain 4 Refrigerent pipe connections Further Information Space collar installation Refrigerant piping installation Electrical wiring installation Condensate drain installation page 5 page 19 page 21 page 23 Outdoor unit installation & location Remote control RCD set up Group control set up Superlynk network SCA-DE interface 4 page 25 page 8 page 9 page 22 Installation of FDT Space Collar For installation of FDT cassette in restricted height ceiling voids. The SPACE COLLAR is used to provide a decorative enclosure for the FDT cassette where the unit protrudes below the level of the ceiling. This allows cassette units to be installed where there is a restricted ceiling void. The space collar height is to be specified by the installer. The cut edge of the ceiling tiles can be concealed above the top edge of the space collar to provide a neat finish The space collar is available in different heights, to allow for the space available within the ceiling void. The collars are precision moulded in glass fibre reinforced plastic, colour textured to match the light grey cassette fascia panel. The ceiling tiles can be installed resting on top of the finished edge of the collar, leaving a neat finish to the installation. NOTE: It is important to make provision for the connection of refrigerant piping and condensate drain, which may be restricted where there is a minimal ceiling void. The height of the space collar must be specified at the time of ordering. The model reference of the FDT cassette must also be specified.

It should be located away from direct sunlight, water splashing, high humidity, or a heat source. It can be located in another part of the building if required. The RCD includes a temperature sensor, which can be utilised as an alternative to the indoor unit return air sensor if preferred. • To install, remove the front panel of the controller from the back by prizing apart. • For surface wiring, make a small cut in the flange of the back, using a sharp knife. • WIRE ENTRY IS FROM TOP ONLY. • Fix the back to the wall. • Connect three wires to XYZ terminal, corresponding to the XYZ terminals on the indoor unit. ENSURE THE XYZ CONNNECTIONS ARE WIRED CORRECTLY. • Use shielded wires, minimum 0.3mm2, for up to 100m length. • Refer to Engineering Data Manual for longer extensions RCD customised setting On the back of the RCD board is a series of dip-switches and jumper wires, which allow alteration and elimination of certain functions and displays. This allows the installer to customise, or simplify the controller to suit the application, and the client’s requirements. The RCD includes an air temperature sensor, which can be utilised as an alternative to the unit integral return air sensor. The RCD includes a 24 hour programmable on/off timer. The programme is set up by adjusting the display using the key pad of the controller. Where an external time control is used (through the CnT port) in preference to the RCD timer, the 24 hour time clock display can be removed, to avoid confusion by the user. This is achieved by cutting jumper wire J3. Where there is a requirement for a 7-day programmable timer (supplied by the installer), this should be wired separately into the CnT port of the indoor unit PCB. Master / slave control Where two controllers are wired to one unit (or one group of units), one is designated the master, the other the slave. This arrangement may be required in a large building, where individual remote controls are located in offices or different areas of a store, and additional controllers are situated in the building manager’s office. The unit (or group) will respond to the last command from either the master or the slave. In some applications, where the RCD integral sensor is required to operate the system, it may need to be located out of reach at high level. The installation of a second RCD would allow the user to operate and adjust the system from a remote location, using the master/slave arrangement.

The RCD will determine the fan speed, heat / cool / auto mode, and temperature selection for all units together. The units will then operate in the same mode, with each individual temperature sensor independently operating the heating or cooling of each system. The indoor unit PCB has an address dial, which must be adjusted to a group address number for each unit in the group, i.e. 0,1,2,3, etc. The address setting also provides a time delay for sequential compressor starts. Group control wiring Up to 16 units RCD remote control The units in the same Group have control board terminals X,Y,Z connected in parallel by 3-core screened wiring. One single controller, or two controllers (master/slave) are connected to the X,Y,Z wiring. Compressor delay timer The address setting of each individual unit within the group also has the function of providing a delay of 1 second between compressor starts. This is to prevent a large power surge, which would result from all compressors starting together. The delay timer function is set into 8 sequential starts, with pairs of units starting together.

Fix suspension bolts (4 no. M8 or M10 – supplied by installer) into the building construction, in the required positions. With the hanging brackets secured to the suspension bolts, the unit (with side panels removed) can be lifted into position, onto the hooks of the brackets. Do not install adjacent to equipment generating magnetic waves or high frequency signals, as the generated noise may cause equipment malfunction. Unit location Installation space Unit location avoiding obstructions (dim. mm) Attention must be paid to the level of the unit. There must be an incline of at least 3mm, to allow drainage of condensate from the drain tray. For semi-recessed installation, a suitable size opening must be made in the ceiling. For a solid ceiling, e.g. plasterboard, it is necessary to make the opening wide enough to allow secure fixing. The space can be filled after installation is complete. 0 ~ 3 mm The unit should be located so as not to cause draft disturbance to a person located directly in the path of the air discharge. Please note: Unit sizes 408 and 508 have high air volume, and are normally suited to retail sites, or large open plan areas. Consideration must be given to the discharge air velocity if applying the larger size units to an office environment. The fixing nuts secure the unit to the brackets. The side panels are replaced. 0 ~ 3 mm Select a suitable location within the room to allow optimum air distribution to all parts of the conditioned space. The rear of the unit can be installed adjacent to a wall (5mm clearance), allowing pipework and electrical connections to be concealed. Condensate drain Model 208 258 308 408 / 508 Air throw (metres) 7.5 8.0 9.0 9.5 The termination of the drain is a ‘push-on’ fitting, 20mm o.d. The condensate can be connected either at the right or left. Ensure there is adequate fall (min 1:50) of the condensate gravity drain. Use rigid drain piping. Please refer to CONDENSATE DRAINS INSTALLATION, page 23. The condensate drain must be insulated, to prevent external condensation. airflow speed at above distance = 0.5m/s Preparation for installation Drill a hole for the pipework – recommended size 70-86mm dia. Use pipe sleeve (accessory) if required. Use Template Sheet to locate positions of suspension bolts. Bolt size M8 or M10. The refrigeration pipework can be routed right, left, top, or rear. NOTE: the suspension brackets can be positioned facing inwards or outwards. Most of the bracket is concealed if facing inwards. See drawings on page 14 for positions of bolt fixings. Ensure suspension bolts are securely fixed into building structure, with a minimum resistive force of 50kg. Condensate pumps A small kit pump can be fitted into the casing of the air conditioner if required. The sump/sensor unit should be carefully installed, ensuring it is lower than the exit connection of the condensate tray. Where the pump includes a ‘fail safe’ switch, the connection to stop the air conditioner can be made through the CnT port of the indoor PCB – terminals 1 & 6. The ‘fail safe’ switch must be voltage free. A connection adaptor, ref: F6001 is available free, from 3D, allowing easy connection to the CnT port. See p 21 for instructions.

Unpack the unit, taking care not to damage the fascia. Remove the wall mounting plate and screw to the wall, ensuring secure fixing to wall structure. Fix one screw first, and then use a spirit level to locate the mounting plate horizontally, marking the remaining fixing holes on the wall, and fix with screws as required. Do not install adjacent to equipment generating magnetic waves or high frequency signals, as the generated noise may cause equipment malfunction. Connection and routing of pipework Unit location The refrigeration pipework is terminated as two copper tubes, with flared fittings. The tubes can be bent, and routed out of the unit at 5 alternative positions, as shown. Select a suitable location within the room to allow optimum air distribution to all parts of the conditioned space. The minimum distance from a wall or obstruction is 120mm. There must be sufficient clearance at the top (dimension ‘K’) to allow for the removal of the casing. K 120 or more The pipes should be bent in the direction required, prior to the unit being installed. 120 or more Condensate hose 208 - K=65mm 258 - K=90mm 308 - K=90mm The unit should be located so as not to cause draft disturbance to a person located directly in the path of the air discharge. The flexible drain hose is located at the bottom rear of the unit, and can be attached to either the left or right connections to the drain tray. The spring clip securing the hose can be easily removed. The drain stub cap must be fitted to the stub, in place of the hose. The hose should exit the unit with the refrigeration pipework, ensuring a sufficient inclination away from the unit – min gradient 1:50. Condensate pump If an internal kit type condensate pump is used, it may be easier to remove the drain hose and to use a short cut length of insulated hose to the sump/sensor component of the pump. The drain stub on the condensate tray is 13mm o.d. Note: condensate pump to be supplied by the installer. The installer must make provision for access to the condensate pump for cleaning and servicing.

Material Only refrigeration quality seamless copper pipe must be used. This must conform to the requirements of BS2871 – Part 2, being of suitable quality for use with refrigerants. Full details of maximum allowable pressures for pipework and fittings are detailed in ‘The Engineers Guide’ published by 3D Air Sales Ltd. Pipework site management To minimise the number of joints, coiled copper should be used in preference to straight lengths. Brazed joints should be used in preference to flared joints. All pipework must be square cut using a propriety pipe cutter to give a clean cut, without copper fragmentation. Hacksaws must not be used. Tubes must be capped to avoid ingress of moisture and dirt. Brazed joints When brazing all pipework must be purged with nitrogen (low pressure oxygen-free), providing positive pressure in the pipe, preventing the formation of cooper oxide particles and scale. An annulus must be used between the feed pipe and the refrigerant pipe, to eliminate the ingress of air, at the point of entry. The formation of scale and particles will result in valves and capillaries becoming blocked. Particles entering the compressor may cause a reaction with the refrigerant oil, resulting in acidic decomposition of the compressor motor windings. Copper pipework must be supported correctly, by suitable clamps, or in perforated cable tray. Where clamps are used, the pipework must be supported at the maximum centres stated below: FIXING CENTRES - SOFT TEMPERED COPPER TUBE o.d. “ 1/4 0.8 1.0 HORIZONTAL VERTICAL 3/8 1.0 1.2 1/2 1.2 1.5 5/8 1.2 1.5 3/4 1.5 1.5 7/8 1.5 1.8 FIXING CENTRES - HALF HARD COPPER TUBE o.d. “ 1/4 3/8 1/2 5/8 3/4 7/8 HORIZONTAL 0.8 1.0 1.2 1.2 1.5 1.5 VERTICAL 1.0 1.2 1.5 1.5 1.5 1.8 11/8 1.5 1.8 Pipe sizes It is essential to use the pipe diameters stated in the Engineering Data tables relevant to each system. The stated sizes must be used for all pipe lengths up to the maximum length. Traps Do not use traps anywhere in the refrigeration pipework. Maximum pipe length Do not exceed the maximum length and vertical separation between the indoor and outdoor units, as stated in the specification data table. Flared joints and pipe bends Place the flare nut on the tube prior to flaring. Use a good quality proprietary flaring tool. Lubricate the tool and the copper pipe with refrigerant prior to flaring. Inspect the flared copper carefully, ensuring there are no cracks or flaws in the copper. Position the pipe and flare nut, and tighten to the following limits: From Nitrogen Cylinder TUBE DIA (o.d. in) 1/4 TORQUE kg/m min 1.6 max 2.0 Oxygen Free Nitrogen gas 3/8 1/2 5/8 3/4 7/8 4.0 5.0 4.0 5.0 9.0 12.0 10.0 14.0 12.0 16.0 Pressure testing Annulus between o/dia. of nitrogen pipe and internal dia of refrigerant pipe, sealed with rubber plug or similar. This is to ensure complete purge of air from refrigerant pipework. Set nitrogen flow meter to 0.05m3/hr, OR (if no flow meter) set pressure reducing valve to 0.2 Bar. Ensure that outdoor unit service valves remain closed for pressure testing. Perform pressure test with dry nitrogen, up to 15bar. Inspect all joints for leakage. Check for any deviation in pressure. 23 Refrigerant charging Low ambient control Vacuum pump Low ambient control Ref: L1220 (For FDC 6 Series OUTDOOR UNITS) NOTE: All equipment used on R22 systems must be kept separate from equipment used on R407C systems. With the outdoor unit service valves closed, the pipework and indoor unit must be evacuated, using a suitable vacuum pump. See diagram below regarding service valves. This is to ensure all air, moisture and other gases are completely removed from the system, and to confirm the leakage testing. A vacuum of –75cmHg should be applied for at least two hours. Application The FDC 6 Series outdoor units are designed to operate, in the cooling mode, in ambient temperatures down to 10 o C. Below this temperature it is likely that over condensing will occur, and the internal cooling performance will be affected. Refrigerant charging It is essential that the correct amount of additional refrigerant is added to the system, before the system is switched on. The length of refrigerant piping (one way) must be measured to the nearest metre, and the additional charge added, as detailed in the installation instructions packed with the unit. Electronic weighing scales Do not attempt to add refrigerant charge unless electronic scales are used. Insulation All refrigerant pipework, both liquid and gas pipes, must be insulated, and insulation joints sealed. The insulation material must be pre-formed Armaflex, or similar, Class “O” fire rated, and vapour sealed. The wall thickness should be at least 6mm for copper pipe diameter of 1/4”, and 13mm for all larger sizes. IMPORTANT Manifolds and tubes for R22 systems must be kept separate from those used on R407C systems. 24 The low ambient kit reduces the condenser fan speed, to prevent over condensing, and to maintain the refrigerant pressure in the system at a level which will maintain its cooling performance. The low ambient control is temperature actuated, with a small thermistor fitted to the copper tubing of the condenser coil. Electrical site wiring - must be installed only by qualified personnel Safety Warning: Refer to safety data on back cover of this manual Power supply wiring Recommended MCB or fuse rating The system designation will indicate the requirement for either 1ph or 3 ph supply, to the outdoor unit e.g. Ref: HEN = 1 phase L +N +E Please refer to unit technical data for recommended sizes. These recommendations are for guidance only, and may vary depending on site conditions. Ref: HES = 3 phase Interconnecting wiring L1 + L2 + L3 + N + E. The system power is connected to the outdoor unit first. All indoor units have 1 phase connection, taken from the outdoor unit terminal block. Wiring specification must be selected and installed in accordance with IEE regulations, and with site requirements. Connect the wiring to the same number terminal on indoor and outdoor units, as shown on the diagram below. The wiring must be secured so that the terminals are not tensioned if force is applied to the wiring. IMPORTANT Do not run the unit until the required amount of refrigerant is added to the system, and the outdoor unit shut-off valves are in the open position. When power is connected, the system will operate immediately.

Time Clock, Remote Switch, and BMS Connection FD Series indoor units are provided with a 6 terminal socket marked CnT. Connection to this port allows remote switching, operation functions, and fault indication. Terminal 1 is a 12V output. Terminal 6 can be connected via a volt free switch or relay to terminal 1 to turn the unit on/off. Additional volt free relays are required for the remaining output signals. Terminals 2,3,4,5 are switched NEGATIVE, i.e. the voltage will drop from 12V to ZERO when actuated. 25 The 6-way adaptor is available from 3D (ref: F6001) allowing easy wiring connection to the CnT terminal socket. Consideration must be given to voltage drop if the 12V control cables are more than 15m in length.

Please refer to the maximum allowable lift for the relevant pumps. Condensate pumps are also included on the KX Inverter Multi systems –models: FDT cassette, FDR ducted cassette, FDTS single discharge cassette, FDTW 2-way cassette, and FDUM horizontal ducted unit. The condensate gravity drain must be rigid heavy duty PVC to BS3505 Class E. Alternatively, copper drain piping can be used, which should be to BS2871 Part 1 Table-Y. This should be connected in a similar way to the rigid gravity drain piping. Care must be taken not to damage or dislodge the pipe outlet from the unit. Condensate piping The drain pipe must be inclined away from the unit at a downward gradient of at least 1 in 50. Traps must not be fitted (except for FDU – see note below). It may be necessary to provide rodding access for cleaning purposes, for a long condensate drain run. For units which include a condensate pump, it is important to install the vertical section within the limitations detailed. 295 - 325mm 100mm or less Pipe insulation must be fitted if there is a possibility of condensation forming on the outer surface of the drain piping, or the connection fitting. Avoid positioning the drain termination where unpleasant odours, or gases, may enter the pipe, and subsequently enter the conditioned space. VP25 joint (field purchase) Where there is sufficient height within the ceiling void, the pump can be utilised to raise the condensate water to a height sufficient to ensure a positive downward gradient to a gravity drain. This eliminates the requirement for a secondary condensate disposal pump. For units with a lift pump, it is essential the first horizontal section and vertical lift are installed within the limitations indicated in the piping diagram. This is to prevent too much water being contained in the vertical lift, which would flood back to the unit and overflow, when the power is switched off. Pipe termination - FDT & FDR The pipe termination is of rigid polythene 25mm o.d. FDT cassette and FDR ducted units include an insulated flexible connection sleeve, complete with a securing clip, which terminates to 25mm i.d., 32mm o.d.

Do not provide air vent in the condensate drain. Do not allow upward elevation. Do not trap. Do not terminate the drain where it can become submersed. 5. Provide adequate support to condensate pipework to avoid sagging. Installation & recommendations - Condensate Drains Common drain piping Where a common drain is to be provided for several units, ensure that discharge water from one unit is prevented from entering another unit. The common drain must be installed below the pumped drain lift of all units. The common drain piping should be larger diameter, minimum 28mm i.d. Drain testing For units with condensate pumps fitted, the electrical supply will need to be connected, and the unit switched on in cooling mode. Supply approximately 1000cc of clean water, using a water feed pump, into the drain tray, through one of the air discharge outlets (with fascia panel removed). Check all joints for leakage, and check sound of lift pump operating (where fitted). If residual water is required to be removed, this can be done by removing the drain plug. For units without a condensate lift pump, the drain piping must be tested in a similar way to the above. 28 Installation of - FDC Outdoor Units Warning: Units with CES or HES designation have electrical terminals 380v 3 Phase Application The outdoor unit is designed to operate in normal outside environments. It should not be installed in an area contaminated by oil, chemicals, or an area with steam or excessive humidity, or close to salt water in a seaside location, or hazardous substances, i.e. flammable gases, vapors, resins, thinners, petroleum, acids. Do not install adjacent to equipment generating magnetic waves or high frequency signals, as the generated noise may cause equipment malfunction. Construction The FDC outdoor units are of robust construction, with panels manufactured from galvanised sheet steel with powder paint coated finish. The air is drawn through the heat exchanger, and discharged horizontally by large diameter fan(s), (two fans on 406/506 & 408/508). Mounting feet are fixed to the bottom plate, which must be used to securely fix the unit. Removable panels allow access to the electrics enclosure, and internal components. Pipe terminations are exposed on FDC 6 Series, and are enclosed on FDC 8 Series, (see diagram for routing of refrigerant pipework). Ensure that the building structure is capable of supporting the weight of the installed equipment, and that vibration transmission through the structure will not cause a disturbance. Make provision for excessive forces of prevailing winds, and site personnel climbing onto units. Warning signs should be fixed where appropriate. Do not install the outdoor units where there is a possibility of causing a noise disturbance to adjacent buildings, in particular if equipment is expected to operate at night time within a residential area. The outdoor units are not suitable for installation close to the sea, as the salt laden air will cause damage to the heat exchangers. The units should not be installed in environments where the atmosphere is contaminated, e.g. chemical processes, engineering workshops, or areas where there is a high level of electronic noise. Minimum space for installation The outdoor unit air flow must not be restricted. The unit must not be installed in a confined space, allow at least 1m clear above the unit. Do not install close to a movement of hot air, or inside a building or roof space, where it is not possible for hot air to escape. Where several units are installed, ensure the air intake is clear of another unit’s discharge air. Outdoor unit location Select a suitable location outside the building, as near as possible to the indoor unit, avoiding long pipe runs. Minimum space for installation & maintenance FDC 6 Series FDC 8 Series L3 L2 Air inlet L4 Air inlet L1 Maintenance space Air inlet 29 Safety Warning: Refer to safety data on back cover of this manual FDC 6 Series outdoor units All units have ‘draw through’ air flow.

This allows the pipes to exit from four different directions – see below. FDC808/1008 for Multi Split the unit. Raise the unit from the ground if necessary, to ensure water does not enter the bottom of the unit. Take necessary precautions to ensure condensate water does not cause a freezing hazard in winter conditions. Electrical connection Ensure power cables are secure. Do not allow power cables to pull on the electrical terminal connectors. Refer to page 21 for details of electrical connections. Terminal connector Cable securing clamp CABLES MUST ENTER FROM BELOW TO PREVENT RAINWATER INGRESS TO ELECTRICS ENCLOSURE Refrigeration pipe sizes It is essential that refrigeration pipe sizes are exactly as those stated in the Product Data Tables. • • • Do not deviate from the recommended pipe sizes. Do not exceed the maximum lengths. Do not exceed the maximum vertical separation. Condensate drainage Heat pump outdoor units will produce condensate water. Ensure condensate water is able to drain effectively from 30 IMPORTANT Do not run the unit until the required amount of refrigerant is added to the system, and the outdoor unit shut-off valves are in the open position. When power is connected, the system will operate immediately.

The electrical power terminations are exposed once the protective enclosure cover is removed. Caution Warning • Ensure that the building structure is capable of supporting the weight of the installed equipment, and that vibration transmission through the structure will not cause a disturbance. • Ensure correct earth grounding. Do not connect earth wire to gas or water pipes, lighting rod or telephone grounding. Incorrect earth grounding can result in electric shock. Where a large system is installed in a small room, it is necessary to provide protection for the rare case of refrigerant leakage into the confined space. This is in order to comply with the concentration threshold as defined by BS4434. • Ensure condensate drainage is carried out correctly. Ensure that odours, vapours or gases are prevented from entering the termination of the drain outlet. • Ensure an earth leakage circuit breaker is installed in the incoming mains power supply. • • Ensure all power supply connections include a fused isolator and/or mains circuit breakers, adjacent to the equipment, for both outdoor and indoor units. Do not install the outdoor units where there is a possibility of causing a noise disturbance to adjacent buildings, in particular if equipment is expected to operate at night time within a residential area. • • Cable connections must be secured, to prevent any tension being taken by the terminal screw connections. • Do not install the units in an area where there may be leakage of combustible gases. A concentration of combustible gases around the units can result in the outbreak of fire. Outdoor units must be properly supported and secured to allow for prevailing winds, and for the possibility of other site personnel (e.g. window cleaners) standing on the units. Warning signs should be fixed where appropriate. • The equipment is not suitable for installation in environments where the atmosphere is contaminated, e.g. chemical processes, engineering workshops, or areas where there is a high level of electronic noise. Outdoor units should not be installed in areas close to the sea, as the salt laden air will cause damage to the heat exchangers. • IMPORTANT Do not run the unit until the required amount of refrigerant is added to the system, and the outdoor unit shut-off valves are in the open position. When power is connected, the system will operate immediately. • All necessary precautions must be taken for the prevention of injury or death by electric shock. • Electrical wiring must be installed only by qualified personnel. • The installation of all wiring must conform to IEE Regulations and to relevant local electrical safety regulations. • • Safety precautions must be observed with regard to pressurised refrigerant systems. Operatives must wear suitable protective clothing and eye protection. • It is illegal to allow HCHF refrigerant to escape to atmosphere. All refrigerant removed from equipment must be correctly decanted into cylinders specifically designated and labelled for this purpose.
