cod. 272157 − rev. 25.02.2005
Caution
We recommend that:
S the manual is retained for the entire service life of the machine;
S the user reads the manually carefully before carrying out any operations on the machine;
S the control is used exclusively for the purpose for which it is intended; incorrect use of the control shall release the manufacturer from any liability.
This manual has been prepared to enable the end−user to carry out only the operations that can be made with the panels closed.
Any operations that require the opening of doors or equipment panels must be carried out only by qualified personnel.
Each machine is equipped with an Electric Insulating device which allows the operator to work in conditions of safety. Switch off
the machine before any maintenance operation to eliminate risks remaining (electric shocks, scalds, automatic restarting, moving parts and remote control).
For "UNDER" units installed on raised floor: switch off the machine before removal of the floor panels within a distance of
850 mm from the machine, to avoid risks of contact with rotating devices.
The panel key supplied with the unit must be kept by the person responsible for maintenance.
For identification of the unit (model and serial no.) in case of the necessity for assistance or spare parts, locate the identification
label on the outside of the unit.

1.1 − Inspection
On receiving the equipment immediately check its
condition; report any damage to the transport company at once.
1.2 − Handling
S Always keep the unit vertically upright and do not
leave it out in the open.
S If possible transport the unit using a fork lift truck;
otherwise use a crane with belts or cables, avoiding
pressing on the top edges of the packing.
1.3 − Operating limits
The units are designed to operate within working
ranges (see Tab. 1).
These limits are referred to new machines or to those
that have been correctly installed and serviced.
The warranty clauses are no longer valid for any possible damage or malfunction that may occur during or
due to operation outside the application values.
1.4 − Identification
The air conditioner can be identified according to the
following nomenclature:

Ideal pipe layout
The discharge operation of the room unit
pressurized with helium (at 3 bar) and the
de−welding of the bottoms from the
connections must be carried out as last
operations, immediately followed by the
connection and emptying of the whole
system.
4.1.1 − General layout (Fig. 1)
1) In soft or hard copper.
The diameter required is stated in Tab. 4.
If the installer intends to use pipes of a larger diameter (e.g. for long winding runs) then consult
Technical Support Department beforehand.
Use as short refrigeration pipelines as possible to
minimize the total charge of refrigerant and the
pressure drops. For long runs (over 30 equivalent
m) contact Technical Support Department.
Lay the horizontal gas pipes with 1% downward
gradient towards the refrigerant flow.
2) Reduce the number of bends, which must be of
large radius, to a minimum.
3) Insulate the piping as specified in Tab. 2. If the
pipes are put next to electrical cables it is advised
to insulate them to avoid induced currents and
damage to cable insulation.
4) There must be a minimum separation of 20 mm between the gas and liquid pipelines.
If this is not possible insulate both lines.
5) Support both horizontal and vertical pipes with
vibration−damping clamps (which include rubber
gaskets). Place these every 1.5 − 2 m.

4.1.2 − Installing pipelines
THE FOLLOWING OPERATIONS MUST BE
CARRIED OUT BY AN EXPERIENCED REFRIGERATION TECHNICIAN.
The discharge operation of the room unit
pressurized with helium (at 3 bar) and the
de−welding of the bottoms from the
connections must be carried out as last
operations, immediately followed by the
connection and emptying of the whole
system.
1) Lay the piping, taking note of the following:
D Welding:
S All joints must be braze−welded.
S Avoid butt welds by using sleeves or enlarging one of the pipes using a pipe opener.
S Use silver−based solders and the correct apparatus.
S Guarantee a correct weld as a refrigerant
leak, or a faulty weld which leads to a leak
later on, can seriously damage the air conditioner.
D Always use large−radius curves (bending radius at least equal to pipe diameter). Bend the
pipes as follows:
S soft copper: by hand or bending device.
S hard copper: use preformed curves. Do not
overheat the pipes when welding so as to
minimize oxidation.
2) Connect the pipes to the condenser:
D Condensers with butt−welded pipe connections: cut the pipe, enlarge it and weld it to the
pipeline.
D Condensers with threaded tap connections:
flange the pipes and connect.
RESPECT THE DIRECTION OF REFRIGERANT FLOW (SEE LABELS ON REFRIGERANT CONNECTIONS).
3) Wash out the pipelines as follows:
a) Plug up the free ends of the pipes.
b) Connect a helium cylinder, fitted with a reducer (max. pressure 10 bar), to the ¼" SAE
Schrader valve of the condenser.
c) Pressurize the pipes with helium.
d) Unplug the pipes instantaneously.
e) Repeat a) − d) several times.
THIS OPERATION IS ESPECIALLY IMPORTANT
WHEN HARD COPPER PIPING IS USED.
When the pipes are more than 30 m long, contact Technical Support Department
4) Open all the room unit shut−off valve.
5) Discharge the room unit pressurized with helium
(at 3 bar) opening the charge valves so that all the
branches of the circuit are discharged (e.g. on the
receiver, on the low pressure side and on the compressor delivery).
6) De−weld the bottoms from the connections of the
room unit.
7) Fix (weld) the pipes to the connections on the air
conditioner.
8) Connect the refrigerant safety valve to the outdoor with a O 16 copper pipe.
4.1.3 − Pipe diameter
The diameters of the connecting pipes between the
conditioner and the condensing unit listed in Tab. 4
must be respected, otherwise the guarantee becomes
invalid.

1) Open all cocks of the system including those used for
pressurizing (ambient unit and condensing unit).
By this operation all the components of the refrigerating circuit must be subject to vacuum.
2) Connect a proper, high efficiency vacuum pump (10)
to the couplings for:
− compressor intake and delivery by using, if available, the three−way Rotalock cocks, coupling 1/4”
SAE (make sure that all the three ways are open),
otherwise the Schrader valves welded on the pipings.
−Three−way Rotalock cock, coupling 1/4" SAE of the
liquid receiver (12) (make sure that all three ways
are open).
− Schrader coupling (13) fit on the compressor or
fan space, if the reheating coil option is available.
3) Provide for a connection with refrigerant cylinder
before making vacuum.
English
4) Make the system vacuum up to a residual pressure
of 0.7 absolute mbar, then go on for 30 minutes.
The pressure must be measured by means of a vacuum pressure gauge (10 b) on the system side.
If the complete vacuum is not possible, this means
that there are some leaks (to be removed according
to the instructions given in 6 below).
NEVER USE THE COMPRESSOR TO CREATE A
VACUUM (THIS INVALIDATES ITS GUARANTEE).
5) Break the vacuum as follows:
a) Close the cock (10a) of the vacuum pump (10).
b) Open the cock (11a) of the refrigerant cylinder
kept vertically to load only gaseous refrigerant.
c) Pre−charge is complete when the pressure of
the gaseous refrigerant contained in the lines,
condenser and Liquid Receiver (L.R.) balances that of the cylinder.
d) At this point both the vacuum pump and the
refrigerant cylinder can be disconnected as
follows:
d1) close the cylinder cock (11a)
d2) close the way 1/4" SAE of the Rotalock
cocks and of the connected Schrader
valves.
6) Inspect all connections/joints using a leak detector. If a leak is found empty the pipes and the condenser, seal the leak and repeat the instructions in
3) − 6).
4.2.2 − R407C precharge
1) Open all cocks of the system including those used for
pressurizing (ambient unit and condensing unit).
By this operation all the components of the refrigerating circuit must be subject to vacuum.
2) Connect a proper, high efficiency vacuum pump (10)
suitable for polyester oils to the couplings:
− Compressor intake and delivery using, if available,
the three−way Rotalock cocks, coupling 1/4"
SAE (make sure that all three ways are open),
otherwise the Schrader valves welded on the pipings.
−Three−way Rotalock cock, coupling 1/4" SAE of the
liquid receiver (12) (make sure that all three ways
are open).
− Schrader coupling (13) fit on the compressor or
fan space, if the reheating coil option is available.
3) Provide for a connection with refrigerant cylinder
before making vacuum.
4) Make the system vacuum up to 0.3 absolute mbar
and after 3 hours check if 1.3 absolute mbar have
not been exceeded. This condition warrants a humidity lower than 50 ppm inside the system.
If the complete vacuum is not possible, this means
that there are some leaks (to be removed according
to the instructions in 6 below).
NEVER USE THE COMPRESSOR TO CREATE A
VACUUM (THIS INVALIDATES ITS GUARANTEE).
5) Break the vacuum as follows:
a) Close the pump cock (10) for the vacuum (10).
b) Open the cock of the refrigerant cylinder (11a)
until the system reaches a pressure value of
about 3 bar.
HIMOD−A/W/F/D/H
13
The refrigerant must be introduced and
charged by taking only liquid fluid from
the cylinder.
c) At this point both the vacuum pump and the
refrigerant cylinder can be disconnected as
follows:
c1) close the cylinder cock (11a)
c2) close the way 1/4" SAE of the Rotalock
cocks and of the connected Schrader
valves.
6) Inspect all connections/joints using a leak detector. If a leak is found, empty the pipes and the condenser, seal the leak and repeat the instructions in
3) − 6).
7) Now the machine is ready for completing the
charge and the start−up.
8) Charge the refrigerant by means of the charge
valve placed at the evaporator inlet.
4.2.3 − Refrigerant charge (A and D)
1) Start the unit as described in para. 7.1.
2) Manually start the compressor (ensure the unit is
not in the dehumidification phase).
3) Guarantee a constant condensation temperature
(preferably 42−45°C); if necessary, partially obstruct the condenser coil surface or limit its ventilating power to obtain these conditions.
4) Charge the unit until the bubbles in the sight glass
have disappeared and the working conditions of
the entire refrigeration circuit have become normal.
5) Verify that the superheat is 7−8 °C (to do this refer
to para. 9.1).
CAUTION: the refrigerant must be
introduced and charged by taking only liquid
fluid from the cylinder through the cock communicating with the bottom of the charge cylinder
(possible check by means of a sight glass fit on the
charge pipe).

The opening of the cutoff cocks of the unit
pressurized with nitrogen must be the last
operation, together with the vacuuming of
the whole system.
This precaution enables the dryer filter
and the oil in the compressor not to be
saturated with humidity.

5.4.1 − Piping installation
THE FOLLOWING OPERATIONS MUST BE
PERFORMED
BY
AN
EXPERIENCED
REFRIGERATION TECHNICIAN.
The condensing base is equipped with a kit of
connection copper pipes that must be used to join the
unit refrigerant pipes with the base refrigerant pipes.
For the connection it is necessary to cut the base
refrigerant pipes, widen them and weld them on the
kit.
Make the connection considering the following:
S Welding:
S the pipes must be braze−welded;
S avoid head weldings using sleeves or widening
one of the pipes with a pipe widener;
S use silver−based welding alloys and suitable
equipment;
S ensure a correct welding, as a refrigerant leak or
a faulty welding with relevant leak may damage
the air conditioner.
5.5 − Coooling water connections (W, F and H only)
The unit must receive cooling water as follows:
a) from an external cooling water source, in open
circuit (para. 5.5.1).
b) using a Dry cooler, in closed circuit (para. 5.5.2).
S Connect the piping as shown in Fig. 27 ÷ Fig. 31.
S It is advisable to use hoses to be connected, with
3−piece joints, to the condenser water inlet and
outlet couplings.
S IMPORTANT: fit a standard strainer on the inlet
water piping.
S Place shut−off ball valves at the conditioner inlet
and outlet to allow easy maintenance.
S It is advisable to install a water drain system at the
lowest point in the circuit.
S Fully drain the piping before connecting it to the air
conditioner.
Caution
5.5.1 − Extra notes for open circuit applications
S Use the unit with mains or well water.
DO NOT USE WATER FROM AN
EVAPORATIVE COOLING TOWER UNLESS
THE FILLING WATER HARDNESS IS
CONTROLLED.
S The water pressure must be 2 − 10 bar (if this is not
so, contact the Technical Support Department).
S The required water flow at different temperatures
is given in our catalogues or on request.
S If necessary (very low water temperature) insulate
both pipes using Armaflex insulation.
S Calibrate the water pressostatic valve (WV) as
described in CHAP. 9.
5.5.2 − Extra notes for closed circuit applications
S The installation in Fig. 26 is indicative only; for
individual installations follow the project diagram.
S Install a pump system calculated, for the flow rate
required, on the basis of the flow and total head of
the system (see project data), and controlled by the
compressor running (see label on the unit).
S Insulate both pipes using Armaflex insulation.
S VERY IMPORTANT: Add water and ethylene
glycol to the circuit, when the ambient temperature
is below zero (referring also to para. 5.6). Do not
exceed the nominal operating pressure of the
circuit components.
S Bleed air out of the circuit.

To prevent the refrigerating fluid from migrating
towards the condenser when the compressor is at a
standstill, and to avoid any intervention of the high
pressure switch when the compressor starts up again,
it is necessary to proceed as follows:
1) provide for a water temperature at the
refrigerating condenser inlet higher than the
temperature of the air−conditioned room.
Or, as an alternative,
2) interrupt water circulation and install the water
pressure valve (WV) on board of the refrigerating
36
condenser when the circulation pump is not
interlocked with the compressor operation.
NOTES:
S To avoid stratification run the circulation pump for
at least 30 min. after adding any glycol.
S After adding water to the water circuit, disconnect
the unit from the sanitary water piping system; in
this way the water mixed with glycol won’t return
into the same piping system.
S After any topping−up of water check the glycol
concentration and add any glycol if necessary.
S The hydraulic features of the system vary by adding
glycol. Therefore check the head and the flow rate
of the pump to be used.

1) Before proceeding with the electrical connections,
ensure that:
S all electrical components are undamaged;
S all terminal screws are tight;
S the supply voltage and frequency are as indicated
on the unit.
2) Power supply cable connections (see Fig. 39):
S Connect the cable to the Line inlet terminal
board.
S Use the cable size defined according to the flow
(see Fig. 40), the supply voltage and the installation type.
S Protect the supply using a back−up fuse.
S Do not fit the supply cable in the raceways inside
the machine electric board.
S Use multipolar cables with sheath (CEI20−22)
only.
3) Wiring connections:
S Connections for remote on−off and hot water
consent must be done by the installer.
S The General Alarm terminals allow remote
alarm signalling.
4) In case of short circuit, check the sticking of the involved remote control switch and possibly replace
it.

S For ordinary places, a low sensitivity is suggested (300 mA) coordinated with the value of the ground heater (IEC 364): Ra v 50/Ia (Art.
413.1.4.1, CEI 64−8);
S In case of frequent over−voltages with mains impulse, it is advisable to install a selective differential and to evaluate the need for adopting
other devices.
S
( mod. 55−65 U A/W only) The value of current (Full Load Ampere) is calculated considering electric heaters running at a capacity of 17,55
kW, configuration F+C and F+C+H.

6.2 − Fan connections
The fan is electrically feeded by an autotransformer
that is connected by the constructor in order to obtain
the nominal air flow and the Available External Static
Pressure (AESP).
To change the factory connection proceed as follow:
− identify the unit’s graph;
− choose the curve’s point where both the air flow
and the static pressure are the most suitable for the
installation;
− check the factory fan blocks connection ( or )
and correct if necessary (see Fig. 41);
− find the output connectors and the bridges corresponding to the graph values (see para. 6.3;
− connect the bridges and the output connectors;
− connect the 400V supply cables to the C" terminals.
After a wiring modification, execute a
loadless test on the autotransformer.
Check the voltage of each wire, in order
not to damage the transformer (always
refer to the output voltage column values).
N.B. A FAN SPEED VARIATION CHANGES THE WORKING CONDITION OF THE UNIT.

7 − Start−up
7.1 −
First start−up (or after long standstill)
TO PREVENT COMPRESSOR DAMAGE THE
CRANKCASE(S) MUST BE PREHEATED FOR AT
LEAST 4 HOURS BEFORE CONDITIONER
START−UP (FAILURE TO DO SO INVALIDATES
THE GUARANTEE).
Start the air conditioner as follows:
1) Open all valves in the refrigeration circuit
according to the instruction label attached to the
valve.
2) W, F and H only: Open all valves in the water circuit
according to the instruction label attached to the
valve.
3) Ensure that the refrigerant charge is correct (see
Chap. 4).
4) Using a leak detector, verify that there are no
refrigerant leaks. If there are any, then repair the
leak and recharge as described in Chap. 4.
5) At least 4 hours before start−up, close QS and QF8
on the electrical panel.
In the Microface" control system factory setting
the stand alone mode is standard. The stand alone
mode gives the possibility of turning on the unit
simply rotating the main switch on the electric
panel. The yellow LED on the Microface case will
light after turning on the unit, because of the
presence of electric power.
If the LED does not light up:
S check the electric panel power supply;
S check the protection devices (e.g.: thermal
switches);
S check the fuses.
6) Mod. 20−24 only: Close QF1.
7) Verify the operation of the crankcase heater.
8) Check that there are no water leakages.
9) D and H only: Bleed all air out of the chilled water
circuit using the bleed valve on the chilled water
coil.
10)If an external condenser or Dry cooler is installed,
start it by supplying power to it.
11)Close all MCBs on the electrical panel.
12)Check the supply voltage on all phases.
13)Check the supply voltage on all phases for the
external condenser or Dry cooler, if fitted.
14)ENSURE THAT THE COMPRESSOR HAS
BEEN PREHEATED FOR AT LEAST 4 HOURS
BEFORE STARTING THE UNIT.
15)Start the unit by pressing ON OFF (see Fig. 42).
English
16)Check the electrical absorption of all components
(see Chap. 6).
17)Check the electrical absorption of the external
condenser/Dry cooler, if fitted.
18)IMPORTANT − If the compressor makes a loud
and unusual noise IT IS NECESSARY TO
INVERT the electrical connections of the phases
supplying the corresponding scroll compressors,
which accept only one direction of rotation.
19)Ensure that the fans rotate in the correct direction
(see arrow on fan).
CAUTION: risk of contact with rotating devices.
20)Ensure that all control system settings are correct
and that there are no alarms (see Control manual).
21) W, F and H only: Verify the water flow.
22)W, F and H only: For closed circuit units ensure that
the water pump starts when the compressor starts.
23)Verify the Fresh Air Intake operation (if fitted).
24)Once the system is operating under load, check the
various components, as follows:
S Verify that the fans are operating properly.
S Ensure that the temperature and relative humidity are being controlled, and that the humidifier (optional) and heating steps (optional) operate when required.
S Ensure that the compressor operates when
required.
S D and H only: Ensure that chilled water valve
operates when required.
S Ensure that the fan operation controller on the
external condenser/Dry cooler (if fitted) is
calibrated correctly, and that it controls the fan
operation.
7.2 − Starting and stopping
S ALWAYS ENSURE THAT EACH CRANKCASE
HAS BEEN PREHEATED.
FOR BRIEF STOPPAGES KEEP THE SUPPLY
TO THE CRANKCASE HEATER.
Turn on the unit operating on the ON/OFF switch placed on the left case of the unit (Fig. 42). If the ON/OFF
remote device is not installed, the green LED on the
Microface case will light up together with the LED placed below the ON/OFF switch. The fan starts immediately (the fan always works when the unit is ON); after 2 minutes the regulation is activated, so the cooling
(compressor), heating (electric heaters), humidifying
and dehumidifying devices can start.
Adjust the set−point as indicated in Control manual.
Stop the unit putting the ON/OFF switch in OFF.
HIMOD−A/W/F/D/H
63
7.3 − Automatic restart
If desired, the unit will automatically restart on the return of power after a supply interruption (see Control
manual).
If the power interruption is expected to be of several
hours, to avoid an automatic cold restart of the
compressor stop the unit before the black−out and, on
the return of power, allow the compressor to preheat
before restarting the unit.
Fig. 42 − On−Off switch
8 − Operation
Unit operation is completely automatic. The below sequence explains how the unit operates :
S The air, sucked in by the fan(s), enters the unit.
S The air is immediately filtered.
S The TEMPERATURE sensor or HUMITEMP (temperature + rel. humidity) sensor (check type
installed), verifies the state of the inlet air, and relays
this information to the control system.
S The control system compares the relayed information to the set point and proportional band values
programmed into its memory: it then commands the
air conditioner to treat the air as follows (see also
Control manual):
S COOLING
A and W only:
The compressor is started and the cold
refrigerant flows through the evaporator, thus
cooling the air passing over it. For compressor
operation see Control manual.
S HEATING
This can take one of three forms:
− electrical heating (optional): the heating elements heat the air passing over them. There are
3 heating steps.
− hot water heating (optional): if hot water is
available, this flows through the hot water coil,
thus heating the air passing over it. The hot water flow is controlled by an on−off (3−way)
valve.
− hot gas reheat (optional used during
dehumidification): the hot refrigerant which
exits the compressor flows through the hot gas
coil, thus heating the air passing over it.
S DEHUMIDIFICATION − optional
A, W and F only:
One of the compressors starts and either the air
flow or the evaporator surface is reduced
(depending on the model), thereby causing
dehumidification (refer also to Control
manual).
D and H only:
See Control manual
N.B.: If, during dehumidification, the ambient
temperature drops below a specified level, dehumidification will be stopped if necessary (see
LOW LIMIT intervention in Control manual).
S HUMIDIFICATION − optional
The humidifier creates steam, which is distributed into the air stream via the steam distribution pipe (see also App. A).
S Filtered new air is injected into the air stream via
the Fresh Air Intake.
64
S
The treated air passes through the fans, which operate continuously, and is then dispersed out of the
unit.
S Under unit only: the air passes from the underfloor
void into the room via air distribution outlets.
For "UNDER" units installed on raised floor:
switch off the machine before removal of the floor
panels within a distance of 850 mm from the machine, to avoid risks of contact with rotating devices
(see Fig. 43).
N.B.: Manual control can be performed using the control
system (see Control manual).
8.1 − Chilled water valve (D and H only)
The 3−way valve controls the chilled water flow. It operates as follows (Fig. 44):
S When the valve is fully open (i.e. max. chilled water
flow) the actuator slot is set to ’1’.
S When the valve is closed (i.e. no chilled water flow)
the actuator slot is set to ’0’.
The valve running time is set to the value specified in
the Control Manual.
Note 1: In the unlikely event of control system failure,
the valve can be manually controlled by means of a 3
mm allen key placed into the actuator slot.
NEVER PERFORM THIS OPERATION USING A
SCREWDRIVER.

3) Measure the superheat as follows:
a) Place a contact thermometer on the tube exiting
the evaporator;
b) Connect a manometer (by a tube of max. 30 cm)
to the compressor suction valve.
c) The overheating is the difference between the
refrigerant saturation temperature corresponding to the pressure read on the manometer and
the real temperature read on the thermometer.
4) The superheat must be 7−8 _C; if not, set the expansion valve as follows:
a) Remove the protective cover;
b) Turn the adjustment screw by 2−4 turns only;
c) Wait 10 minutes.
d) Measure the superheat and repeat the operation if necessary.
N.B.: If the superheat is too low (compressor cool
to the touch) the screw must be turned in a clockwise direction.
If the superheat is too high (compressor hot to the
touch) the screw must be turned in a counterclockwise direction.

9.2 − Adjustment of the hot gas injection valve
THIS OPERATION MUST BE CARRIED OUT BY
AN EXPERT REFRIGERATION TECHNICIAN.
9.2.1 − Features
This valve is installed in some special versions (see relevant refrigeration circuits). It enables a partial control of the evaporating pressure, so as to avoid evaporation temperatures lower than zero degrees centigrade and thus any ice formation, even with low temperatures of the return air. It is installed on a by−pass between the high pressure and the low pressure of the refrigerating system. It detects the pressure at the evaporator outlet through a capillary. It injects hot gas exiting the compressor in a section of pipe before the evaporator through the gas−liquid mixer, so as to keep
the pressure higher than the set value. See the refrigerating scheme in the Fig. 3 ÷ Fig. 21.
9.2.2 − Adjustment
The min. evaporating pressure is kept by calibrating
the valve as follows.
S

Drastically reduce the conditioner air delivery.
Check by a precision pressure gauge the evaporating pressure and the relevant saturation temperature.
Adjust the valve acting on the adjustment screw, so
that it intervenes when the evaporation temperature has decreased to 2°C.
Then check the correct operation of the thermal
expansion valve.

S When either removing (for repairs) or charging
refrigerant this must always be done on both the
high and low pressure sides of the compressor
simultaneously.
S The compressor copper plated steel connections
should be welded with a silfos material containing
a minimum of 5% silver.
10.1.1 − Refrigerant charge of the water−cooled units
(W, F and H)
1) Start the unit as described in para. 7.1.
2) Manually start the compressor (ensure the unit is
not in dehumidification).
3) Wait a few minutes to allow conditions to stabilize.
4) Check whether there are any bubbles visible in the
sight glass. If there are any, this means there is a
leak, which must be traced (using a leak detector)
and repaired; then recharge the unit until no
further bubbles are visible.
5) Using a manometer, check that the evaporating
temperature is above 0_C.
6) Verify the water pressostatic valve (WV) setting
(CHAP. 8).
7) Verify that the superheat is 7−8 _C (to do this refer
to para. 8.1).

We therefore recommend exposing the oil for as short
a time as possible (a few minutes) and, in case of
topping up, using exclusively the oil indicated on the
refrigerating compressor.
Normally 1 or 2−liter cans are available for this
purpose; once they are opened, they must be
completely used up. They must not be used after a long
period, as they absorb humidity.
It is therefore obvious that the taps of the compressor
must only be turned after the whole plant has been
subjected to a vacuum and partial filling.
10.1.4 − Oil topping−up of an installed circuit
If oil leakages occur, the topping−up operation is
necessary.
Please contact Technical Support Deparment if
topping−up is necessary.
The oil to be used when topping up (only if
there are any leaks) is SUNISO 3GS.

Start−up and operation
App. A.4.1 − Start−up
Before using the humidifier, check the following:
S Supply and drain connections.
S That the cut−off tap is open.
S All wiring.
S Earthing.
S Steam hose connection between steam cylinder
and distributor.
To start the humidifier simply switch on the air conditioner, which will in turn automatically start and stop
the humidifier as required. The (adjustable) parameters which determine humidifier operation have already been factory−preset (see HIROMATIC manual).
App. A.4.2 − Operation
Water, provided it contains even a small quantity of
salts in solution, is a conductor of electricity. Therefore, if the steam cylinder is filled with water and a potential difference is applied between the production
electrodes, the water behaves like an ordinary electrical resistance and becomes hot, thus creating steam.
The steam production rate can be controlled by varying the water level in the cylinder; the higher the water
level, the deeper the electrodes are immersed into it
and the greater the steam production.
Note 1
In case of low water conductivity the cylinder 93H (9.0
kg/h) or 53H (4.5kg/h) can be substituted with the cylinder 93L or 53L without changing the power supply.
Please remember to set the right cylinder type into the
Control system.
The steam production will remain unchanged.
Note 2
When starting with an empty cylinder, the water conductivity is normally insufficient for the HUMIDIFIER STEAM OUTPUT to be reached immediately.
Therefore the humidifier produces as much steam as
possible to fill the cylinder completely. Any evaporation water is immediately refilled.
The drain valve is kept shut and therefore, as the steam
does not contain any salts, the conductivity of the water within the cylinder slowly increases until the HUMIDIFIER STEAM OUTPUT is obtained.
The length of the start−up period depends upon the
water conductivity. For very conductive water it may
occur that the HUMIDIFIER STEAM OUTPUT is
obtained immediately.
App. A.5 −
Maintenance
App. A.5.1 − Removing the steam cylinder
To remove the steam cylinder, proceed as follows (see
Fig. 3):
1) Open the General Switch relative to the humidifier.
2) Drain all the water from the cylinder by activating
"HUM. DRAIN" in the HIROMATIC Service
menu several times (see Microface manual).
English
3) Disconnect the steam hose (S) (made of non−conductive rubber).
4) Disconnect the power electrode wires (P) and level
sensor wire (L).
5) Undo the clip (R).
6) Pull the cylinder (C) out of its gland at the bottom
(G).
App. A.5.2 − Replacing the steam cylinder
When the steam cylinder is approaching the stage
where it needs to be replaced, warning A25 is generated (see HIROMATIC manual) to advise the user
that the cylinder must be replaced. To replace the cylinder, proceed as follows (see Fig. 3):
1) Carry out the instructions in para. Removing the
steam cylinder.
2) Using the new cylinder, carry out 4)−6) of para. 5.1
in reverse order.
3) Connect the steam hose (S); the clip on the hose
needs to be tightened only slightly.
4) Manually switch the humidifier on for 2−3 minutes
(in the HIROMATIC Service menu). Then switch
it off.
5) Drain the water as for 2) in para. Removing the
steam cylinder.
6) If the air conditioner features a HIROMATIC with
Graphic display, reset the humidifier working hours
(window no. 1 of PARAMETER MENU) to zero.
7) Close the General Switch relative to the humidifier.
App. A.5.3 − Annual maintenance
Annually (e.g. before any close−down period) carry
out the following service on the humidifier (see Fig. 3):
1) Carry out the instructions in para. Removing the
steam cylinder.
2) Disconnect the supply (F) and drain (D) valve wires.
3) Unscrew and remove the drain tank (T).
4) Unscrew the drain valve assembly screws (V).
5) Remove the drain valve assembly.
6) Unscrew and remove the drain valve solenoid (O).
7) Unscrew and remove the drain valve armature (A).
8) Clean all parts of the drain valve using a commercially available descaling agent (to remove any incrustations).
9) Detach the hose from the supply valve.
10)Remove the supply valve connection (N).
11)Unscrew the supply valve (F) and remove it.
12)Clean the supply valve using a jet of water.
13)Replace any hose which has become hard and
brittle.
14)Thoroughly flush the drain line (E).
15)Reassemble the humidifier by carrying out the
above instructions in reverse order.
ATTENTION
Always empty the cylinder completely before any close−down period.
