Prior to any intervention in the appliance,
installation, start-up, use and maintenance,
the staff in charge of these operations
must be familiar with all the instructions
and recommendations appearing in the
appliance installation manual, likewise the
elements in the technical dossier of the
product.
The staff in charge of the appliance recep-
tion must carry out a visual control to verify
the damages which might have occurred to
the appliance during transport.
Installation of the appliance close to a
heat source, combustible and corrosive
materials or the air intake conduit of an
adjacent building is prohibited.
The appliance is to be installed, maintained
and repaired by qualied staff pursuant to
the demands of the guidelines, current

may fall and cause an accident.
Do not use any coolant other than R-407C.
The mixture of gases in the cooling cycle
can lead to damage or impaired perfor-
mance.
While connecting the outdoor unit, keep
the cabling conduit rigid. Faulty cable
tting can cause overheating, electrical
discharges or re at these connections.
Place the drainage hose in a suitable posi-
tion. An improperly tted hose will force
the water back to the room, thus damaging
the furniture.
During the appliance maintenance phase,
heat sources and cooling uids must be
controlled.
The system must always be earthed. If it is
not, this may lead to electrical discharges.
Prior to intervening the refrigeration circuit,
it is compulsory to stop the appliance for a
few minutes to reduce the compressor and
piping temperature, because during normal
functioning they may reach temperatures
exceeding 100ºC involve the risk of burns.
Any welding intervention is to be perfor-
med by qualied welders.

(1) The rate voltage of this product is monophase
(230V/1Ph/50 Hz) or triphase (400V/3Ph/50Hz).
(2) Perform wiring work in accordance with stan-
dards so that the room air conditioner can be
operated safely and positively.
4.8 ELECTRICAL WIRING
(1) Connect the connection cords  rmly to the
terminal block. Imperfect installation may
cause a re.
(2) If the indoor unit connection cord (to the
outdoor unit) and power supply are wired inco-
rrectly, the air conditioner may be damaged.
(3) Always connect the ground wire.
4.9 MAINTENANCE INSTRUCTIONS
- Never add oil to the appliance; the compressor
is lled with polyaldohol oil, a special oil which
cannot tolerate the presence of other oils.
- The instruments used for lling, pressure measu-
rements, emptying under vacuum and recovering
the uid, must be compatible and only used for
the R-407C uid.
- The weight of the refrigerant contained in the
storage bottle must be checked constantly. Do
not use it from the moment the remaining weight
is less than 10% of the total weight.
- In the case of a new charge do not use the char-
ging cylinder, use a balance and a dip pipe type
R-407C cylinder, charge the weight of R-407C as
per the value indicated on the unit’s identication
plate (for “split systems”, refer to the installation
instructions as the charge must consider the
length of the connecting lines).
- The charge must be undertaken in liquid phase.
- In the case of leakage, do not complete the
charge: recover the remaining refrigerant or
recycling and perform a total charge. Recovery,
recycling or the destruction of the uid must be
done in compliance with the laws in force in the
country concerned.
- If the refrigerant circuit is opened, you must
avoid the entry of air into the circuit as much as
possible, replace the lter drier and perform the
“vacuum operation” at a minimum level of 3.0
mbar (static).
4- OUTDOOR UNIT INSTALLATION
4.5 HEAT INSULATION ON THE PIPE JOINTS
- Put coupler heat insulator on the joints.
AIR PURGE
- Check if the piping connections are secure.
- Check that the stems of both 3- way valves are
closed fully.
- Operate the vacuum pump and start pump
down.
- Pump down the system for at least 15 minutes,
then check if the compound pressure gauge reads
- 100kPa (- 76 cm Hg, -1bar)
- At the end of pump down, close the low pressure
side gauge of the gauge manifold fully and stop
the vacuum pump.
- Slowly loosen the valve stem of the 3- way
valve.
- Firmly tighten both 3- way valves blank cap and
the charging port cap.
4.4 CHECKING THE PIPE CONNECTIONS FOR
GAS LEAKING
- For both the indoor and outdoor unit sides, check
the joints for gas leaking by the use of a gas
leakage detector without fail when the pipes are
connected.
ADDITIONAL CHARGE
- Refrigerant suitable for a piping length of 10 m. is
charged in the indoor unit at the factory.
- When the piping is longer than 10 m., additional
charging is necessary.
4.6 GAS LEAKAGE INSPECTION
