The total refrigerant charge amount has been reduced by more than 50%. (2) The indoor outdoor interconnection signal wiring has been done away with. The microcomputer chip is installed in the indoor unit. There is no need for the unit to communicate between the outdoor and indoor units so the unit is more resistant to electromagnetic noise thus the incidence of microcomputer malfunction has been reduced. The compressor in the outdoor unit has its own self protection function, that reacts according to abnormal high pressure and excessive high temperature. (3) There are only five power lines between the outdoor and indoor unit, As no signal wire is used there is no need to separate the power line from the signal line. One cab tyre cable with 6 wires encased in one sheath is enough for conducting the wiring work between the outdoor unit and the indoor unit. This contributes to simpler wiring work in the field. (4) All models have control valves protruding from the outdoor unit for faster flare connection work in the field. (5) Operation noise has been drastically reduced by increasing the number of high performance fans and by through sound insulation. (6) When installing, the optimum outside static pressure can be set using the fan controller. (7) With the height of all equipment made uniform at 360mm and neatly installed into the ceiling, the installation of equipment with different capacities into the same ceiling space is made easy. 15.1.2 How to read the model name Example: FDU 30 8 H EN-SA Applicable power source ...

How to obtain the cooling and heating capacity Example : The net cooling capacity of the model FDU308HEN-SA with the air flow “High”, the piping length of 15m, the outdoor unit located 5m lower than the indoor unit, indoor wet-bulb temperature at 19.0 ˚C and outdoor dry-bulb temperature 35 ˚C is Net cooling capacity = 7100 × FDU308HEN-SA 1.00 Air flow “High” × (0.98 - 0.01) × Length 15m. Height difference 5 m 1.0 = 6887 w Factor by air temperatures 609 FDU-H 15.2.7 Characteristics of fan How to interpret the blower characteristics table Example ¡What is the Fan Controller’s Volume Number setting if, at the high operation speed of FDU308-A (60Hz), it is required to have 140Pa (14mmAq) outside static pressure at 24m3/min airflow volume as the operation point? Move the 140Pa (14mmAq) outside static pressure point to the right as shown in the diagram below. The “ a -point”, i.e. where this intersects with the solid curve tracing the 24m3/min airflow volume upwards, is the appropriate Volume Number. In this example the appropriate Volume Number is “No. 6”. ¡In this situation, a condition of 19.7m3/min airflow volume at 93Pa (9.3mmAq) outside static pressure can be predicated at Low Tap and it can be concluded that operation is possible. Always follow the procedure in “ b -point” to verify that the condition at Low Tap is not outside the Feasible Operation Airflow Volume Range. Notes (1) Circled values in the Special Feature Table indicate Fan Controller Volume Numbers. Volume Numbers with no entry are outside the Feasible Operation Airflow Volume Range and therefore operation is not possible. (2) The Fan Controller Volume Number is set at “No.5” when shipped from the assembly plant.

equipment for FDT(N) heat pump type. Refer to page 317. 15.5 APPLICATION DATA SAFETY PRECAUTIONS • Please read these “Safety Precautions” first then accurately execute the installation work. • Though the precautionary points indicated herein are divided under two headings. WARNING and CAUTION , those points which are related to the strong possibility of an installation done in error resulting in death or serious injury are listed in the WARNING section. However, there is also a possibility of serious consequences in relationship to the points listed in the CAUTION section as well. In either case, important safety related information is indicated, so by all means, properly observe all that is mentioned. • After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please explain operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner’s manual. Moreover, ask the customer to keep this sheet together with the owner’s manual. WARNING • This system should be applied to places of office, restaurant, residence and the like. Application to inferior environment such as engineering shop could cause equipment malfunction. • Please entrust installation to either the company which sold you the equipment or to a professional contractor. Defects from improper installations can be the cause of water leakage, electric shocks and fires. • Execute the installation accurately, based on following the installation manual. Again, improper installations can result in water leakage, electric shocks and fires. • When a large air-conditioning system is installed to a small room, it is necessary to have a prior planned countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration. In regards to preparing this countermeasure, consult with the company from which you perchased the equipment, and make the installation accordingly. In the rare event that a refrigerant leakage and exceeding of threshold concentration does occur, there is the danger of a resultant oxygen deficiency accident. • For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient, injury can result from a falling of the unit. • Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons and hurricanes, etc. Improper installations can result in accidents due to a violent falling over of the unit. • For electrical work, please see that a licensed electrician executes the work while following the safety standards related to electrical equipment, and local regulations as well as the installation instructions, and that only exclusive use circuits are used. Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks and fires. • Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted to the terminal connection part, through properly securing it. Improper connection or securing can result in heat generation or fire. • Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper installation can also result in heat generation or fire. • When setting up or moving the location of the air-conditioner, do not mix air etc. or anything other than the designated refrigerant (R22) within the refrigeration cycle. Rupture and injury caused by abnormal high pressure can result from such mixing. • Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this company can result in water leakage, electric shock, fire and refrigerant leakage. CAUTION • Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightning rod or a telephone ground wire. Improper placement of ground wires can result in electric shock. • The installation of an earth leakage breaker is necessary depending on the established location of the unit. Not installing an earth leakage breaker may result in electric shock. • Do not install the unit where there is a concern about leakage of combustible gas. The rare event of leaked gas collecting around the unit could result in an outbreak of fire. • For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate it to prevent condensation. Inadequate plumbing can result in water leakage and water damage to interior items. 623 FDU-H NOTICE All Wiring of this installation must comply with NATIONAL, STATE AND LOCAL REGULATION. These instructions do not cover all variations for every kind of installation circumstance. Should further information be desired or should particular problems occur, the matter should be referred to Mitsubishi Heavy Industries, Ltd. through your local distributor.

In order not to transmit vibration from the main unit of air conditioner to the ceiling or slab, it is necessary to provide means to prevent vibration, for example, a canvas coupling on the duct or rubber cushion on the main unit of air conditioner. A damper to control air volume should be installed on the joint of OA duct to facilitate control of air capacity after the installation. Location and from of blow outlet should be selected so that air from the outlet will be distributed all over the room, and equipped with a device to control air volume. Make sure to provide an inspection hole on the ceiling. It is indispensable to service electric equipment, motor, functional components and cleaning of heat exchanger. Make sure to insulate the duct to prevent dewing on it. Thickness of insulating material is 65 mm minimum. 2 7 Silencer chamber (blowout) 3 Silencer chamber (intake) Detail of section A (Vibration prevention of hanger) 4 Wind capacity control damper Insulation 3 4 5 6 7 1 If a duct is not provided at the suction side but it is substituted with the space over the ceiling, humidity in the space will increase by the influ2 ence of capacity of ventilation fan, strength of wind blowing against the outdoor air louver, weather (rainy day) and others. 1 a) Moisture in air is likely to condense over the external plates of the unit and to drip on the ceiling. Louver to Unit should be operated under the conditions as listed in the above outdoor air table and within the limitation of wind volume. When the building is a concrete structure, especially immediately For ventilation after the construction, humidity tends to rise even if the space over the ceiling is not substituted in place of a duct. In such occasion, it is necessary to insulate the entire unit with glass wool (25 mm). (Use a wire net or equivalent to hold the glass wool in place.) b) It may run out the allowable limit of unit operation (Example: When outdoor air temperature is 35°CDB, suction air temperature is 27°CWB) and it could result in such troubles as compressor overload, etc. c) There is a possibility that the blow air volume may exceed the allowable range of operation due to the capacity of ventilation fan or strength of wind blowing against external air louver so that drainage from the heat exchanger may fail to reach the drain pan but leak outside (e.g. drip onto the ceiling) with consequential water leakage in the room. 2 Unless vibration isolation is provided between the unit and duct and between the unit and the slab, vibration will be transmitted to the duct so that vibration noise may generate from between the ceiling and blow outlet or vibration may be transmitted to the slab. Make sure to provide an effective vibration prevention means. Bad example of duct work <Simplified method for determination of duct dimensions> <Table of simplified selection of duct dimensions> In the following method, it is assumed that the friction resistance per unit length of duct is 1 Pa/m (0.1 mm Aq/m) and a side of duct is 250 mm. Air volume rating is assumed to be FDU508HES-SA, 60 Hz.

Blowout section Calculate based on 25 Pa (2.5 mmAq). Chamber Calculate by taking 1 pc. as 50Pa (5 mmAq). Suction grill (with filter) Calculate by taking 1 pc. as 40Pa (4 mmAq). Section B Section A (4) Drain Piping (a) Drain piping should always be in a downhill grade (1/50~1/100) and avoid riding across an elevation or making traps.

Also, fix the piping at a point as close as possible to the unit. (c) For drain pipe, use hard PVC general purpose pipe VP-25(I.D.1˝) which can be purchased locally. A downhill grade of 1/100 or more Secure the elevation as high as possible (approx. 100 mm) V.P.30 625 FDU-H (d) When constructing drain piping for several units, position the common pipe about 100 mm below the drain outlet of each unit as shown in the sketch. Use VP-30 (11/4˝) or thicker pipe this purpose. (e) Be sure to provide heat insulation to hard PVC pipes of indoor placement. (f) Do not ever provide an air vent. (g) Avoid postitioning the drain piping outlet at a place where generation of odor may be stimulated. Do not lead the drain piping direct into a sewer from where sulfur gas may generate. <Provision of trap> Since the drain outlet is disposed at a position that makes the pressure negative, it is necessary to provide a trap (during the piping work) in order to prevent water leakage due to rising of water level in the drain pan. Trap must be so constructed to facilitate cleaning. It should be better to employ a "T" joint as shown below. In addition, the height of trap should be as specified below. The trap should be provided close to the unit. If the duct is connected and then the blower is operated, inside air pressure will become negative compared with the atmospheric pressure. Pressure head loss, suction side Duct Duct In running In stopping Air outlet grille Example: If the pressure loss at the suction side, such as the suction grill, air filter and duct, is 100 Pa (100 mm Aq), the level of drain water will rise approx. 10 mm higher than the state of operation stop. Drain connection Unit H1 Drain pipe Drain pan H2 Suction grill 10 mm Air filter Provide a trap on way of the drain pipe as shown at left. H1=100 mm or static pressure of blower H2=1/2 H1 or 50 ~ 100 mm (5) Drain Test When the drain piping work is over, inject water to inspect if the piping is arranged properly or not. Remove the side panel and supply gradually 1,000 cc of water to see if water is drained smoothly or not. Check also for water leakage. (6) Operating method of fan controller This unit allows to continuously adjust the air volume with the fan controller switch which is built the electric equipment box. It is not necessary to control the air volume (outside unit static pressure adjustment) with the damper, etc. at the duct side. Select the point of operation so that it will be within the range of air volume withch can be operated. (Refer to the limitation of air capacity as shown below.) Location of the fan controller in the electric equipment box and the operating method are shown below. Refer in advance to the blower characteristics quoted in the separate engineering data, and select the number on the scale of fan controller switch. Referring to the figure below, adjust the number on the scale of fan controller switch at the number selected during the test run after completion of electrical work and check if the intended air volume is obtained or not. This connector is provided for emergency purpose and is used when the fan controller becomes out of order. If this connector is connected to the connector of the printed circuit board, the unit can be operated with 100% capacity. This connector is connected to the printed circuit board. Turn this knob. (Controlled within the range of scale 1 to 8 on the switch.) 15.5.2 Installation of remote controller This is same as FDT(N) heat pump series, Refer to page 337. 15.5.3 Installation of outdoor unit This is same as FDT(N) heat pump series, Refer to page 338. 15.6 MAINTENANCE DATA This is same as FDT(N) heat pump series, Refer to page 348. 626
