Cutting and flaring of the pipe
- Cut the copper pipe at the set length, using a pipe cutter; there is to be
a suitable straight section near the outdoor unit in order to enable the
flare to be remade if necessary.
- Remove any burrs from the end of the pipe, using a countersink. This ope-
ration is very important in order to obtain good quality flaring (Fig. A).
6. EXTERNAL UNIT INSTALLATION
6.3 Refrigerating circuit piping
The connections for the refrigerating piping are sealed with a flared end and flare-nut.
The outdoor unit contains the whole charge of the refrigerating system and is equipped with valves with flare-nut connections and service fitting connection.

Attention!
Use only new, annealed, degreased and deoxidated copper pipe of the
CU DHP for UNI EN 12735-1 type.
The copper pipe for plumbing services is not suitable.
Refrigerating lines
Path and bending of pipelines
- Define the pipeline path with the fewest possible bends.
- Bend the pipe with a suitable pipe-bending machine to avoid dangerous
flattening.
- For wide bends, use cylindrical surfaces for support, working very
delicately.
Attention!
Do not bend the copper pipe more than three times in the same place, to
avoid the danger of splitting it.
Warning!
When you remove the burrs, keep the end of the pipe towards the bottom,
avoiding scraps from dropping inside it. The unions placed on the pipe
fittings of the units are to be immediately
removed before use, working in such a way that the cocks remain open
for the minimum time possible.

Insulating
Fig. D
Flaring tool
Fig. E
Example of incorrect flarings
Use an insulating tube in vapour-proof closed-cell polyurethane foam at
least 9 mm in thickness. (Fig. C).
Wrap any uncovered areas with adhesive tape which has similar cha-
racteristics to the insulating material used for the pipeline.
6.3.3 Esecution Flaring
Carrying out the flaring properly is essential for the union to seal, it must
therefore be carried out with particular care and the appropriate flaring
tool. (Fig. D/E).
It is important to apply refrigerating oil to the mating surfaces of the
flared end and the fitting before they are joined.
This precaution prevents possible gas leakage.
Attention!

Earthing wire should not be con- nected to the gas pipe,
water pipe, lightning rod or phone line, incorrect earthing
may cause shock.
6.4 Electrical supply
Electrical connections have to be done by qualified personnel, by observing
the current rules in the place where the air conditioner unit has to be
installed.
Electrical connection has to be preceded by a careful control about com-
patibility between the electrical supply line and the features of the unit
you want to connect.
In the electrical supply line of the unit it is mandatory to foresee a bipolar
switch (a differential one) with a contact separation of at least 3mm in
every pole.
Attention!
Before doing any work on the units, make sure that the main electrical
supply has been disconnected.
Before interrupting the power supply by means of the switch, turn the air
conditioner off with the remote control.

Note:
after the unit has been switched off, or after the operating mode has
been changed, the compressor will not start before 3 minutes.
During operation in Cooling mode, frost may form on the indoor unit or
on the pipes.
Run the unit as indicated in the instruction manual. Explain the operation
of the air conditioning unit to the end user using the instruction manual.
Points to confirm during the operating test:
Are there gas leaks from the pipe couplings?
 Have the pipe couplings been thermally insulated?
 Are the electrical connections of the indoor units and of the outdoor
unit correct?
 Is the cable connecting the indoor units and the outdoor unit firmly
attached?
 Is the condensate drained correctly?
 If the earth wire firmly connected?
 Does the supply voltage comply with the regulations in force?
 Can you hear strange noises?
 Is operation in Cooling mode normal?
 Does the room temperature sensor work correctly?
7.2 Coolant recovery
The coolant must always be collected in special cylinders using the
recovery unit and following the operating instructions of the same.
Note:
the coolant must not be released into the atmosphere as specified in
the regulation (CE) no. 2037/2000 of the European Parliament and of
the Council.
6. EXTERNAL UNIT INSTALLATION7. CHARGE AND TEST OF THE SYSTEM
7.1 Operating test (the first ignition must be done
in Cooling mode)
Before starting the test, make sure that the following tasks have been
completed correctly:
- Piping;
- Connection of power cables;
- Correct correspondence of the indoor and outdoor unit;
- Top up coolant (if necessary);
- Make sure that all the shut-off valves are completely open;
- Check that the voltage supplied to the outdoor unit and to the indoor
units is 230V.
- To perform the test in Cooling mode, set the minimum temperature to
16°C.
- To perform the test in Heating mode, set the maximum temperature
to 30°C.
- First test each indoor unit one at a time both in Cooling mode and in
Heating mode, then test the simultaneous operation of all the indoor
units.
- After running the unit for 20 minutes, measure the delta T of the indoor
unit.
Note:
If the room temperature is below 16°C it is not possible to perform the
operating test in Cooling model using the remote control; in the same
way, if the room temperature is higher than 30°C, it is not possible to
perform the operating test in Heating mode.

7. CHARGE AND TEST OF THE SYSTEM
7.2 Draining and filling
the refrigerating circuit with R 32
- The operations indicated below must be carried out only after discon-
necting the air conditioner from the power supply.
- The outdoor unit holds a refrigerant R 32 charge suitable for pipelines up
to 5 meters in length.
- Do not mix any substance other than the specified refrigerant R 32 into
the refrigeration cycle.
- When refrigerant gas leaks occur, ventilate the room as soon and as
much as possible.
- R 32 , as well as other refrigerants, should always be recovered and
never be released directly into the environment.
- Use a vacuum pump for R 32 exclusively. Using the same vacuum
pump
for different refrigerents may damage the vacuun pump or the unit.
- To use tools (manometric group, flexible and it pumps empty) exclusively
devoted to working fittings with refrigerant
R 32
- Do not substitute or mix one gas with another, as they are not compat-
ible.
- For and R 32 charge, it is imperative to introduce the refrigerant in
liquid phase.
7.1.1 Vacuum and charge procedure
- Tighten the unions (Fig. A) as indicated at page 6.3.
- Connect a vacuum pump to the service connection 3(fig. A), via a set
of portable pressure gauges.
- Keep it running until a vacuum of 1 mBar or below has been reached, if
the pump is fitted with a vacuum gauge, or for at least 25 minutes if a
vacuum gauge is not available..
- Close the valve on the set of gauges connected to the pump, and turn
the pump off.
- If the pressure gauge set is fitted with a vacuum gauge, wait at
least 5 minutes, then check that the vacuum in the system has been
maintained. If not, look for the cause of the leak.
- For pipelines longer than 5meters, it is necessary to fill the circuit, using a
measuring cylinder or an electronic balance, with a quantity of R 32 liquid
phase proportional to the size and length of the pipes used, as shown in
the following table page 11.

After the addition of any refrigerant gas charge which may be necessary:
- Remove caps B(Fig. A) and with the appropriate key open the valves (it
is good practice to open them all the way, then close them by a half of a
turn).
- Put caps B(Fig. A) back on and tighten them.
- Check for possible leaks at the unions with a refrigerant gas leak
detector.
- Disconnect the equipment used from the union 3(fig A) and close the
service connectors, refitting their caps tightly.
7.1.2 Precautions when adding refrigerant
- Fill from the liquid pipe in liquid form.
- Precautions when adding R32. It is a mixed refrigerant, so adding it in
gas form may cause the refrigerant composition to change, preventing
normal operation.
- Before filling, check whether the cylinder has a siphon attached or not.
(lt should have something like “liquid filling siphon attached” displayed on
it.)
Fig. A
Filling a cylinder with an attached siphon
Stand the cylinder upright when filling.
There is a siphon pipe inside, so the cylinder need not
be upside-down to fill with liquid.
Filling other cylinders
Turn the cylinder upside-down when filing .
Check the type of refrigerant to be used on the machine namiplate.
