INSTALLATION WARNINGS
WARNING: Make sure that the power supply is disconnected before carrying out any work on
the unit.
WARNING: Wear appropriate personal protective equipment before carrying out any work on
the unit.
WARNING: The appliance must be reinstalled in accordance with national system regulations.
WARNING: Wiring and installation must only be performed by a qualified technician trained to
install, modify, extend and service the unit and perform safety and functionality tests.
WARNING: Install a device, master switch or electric plug that will allow all the power from the
appliance to be switched off.
WARNING: Use only copper pipes for refrigerant connections.
WARNING: For the connection between the units, use only annealed and deoxidized
copper pipe for conditioning and refrigeration and insulated with expanded
polyethylene of min. 8 mm.
The following information is essential for correct unit installation. However, the installer should
use his or her experience to install the unit according to specific requirements.
Do not install the unit in locations where there are flammable gases or acid or alkaline
substances that may irreparably damage the copper-aluminium heat exchangers or
internal plastic components.
Do not install the unit in offices or kitchens where oil vapours mixed with treated air
may settle on the exchange coils, reducing performance, or on the unit's internal
parts, damaging the plastic components. When installing or relocating the unit, be
sure to keep the refrigerant circuit free of air or substances other than the specified
refrigerant.
Any presence of air or other foreign matter in the refrigerant circuit will cause
increased system pressure or compressor failure, resulting in damage.
When installing or relocating the unit, do not charge refrigerant that does not
conform to that indicated on the nameplate or unidentified refrigerant. Otherwise, it
may cause abnormal operation or an accident.
When refrigerant needs to be recovered, in case of transfer or repair of the unit, make
sure the unit is operating in cooling mode. Then, completely close the valve on the
high pressure side (liquid valve). Approximately 30-40 seconds later, completely
close the valve on the low pressure side (gas valve), stop the unit immediately and
disconnect the power supply. The time for refrigerant recovery should not exceed 1
minute.
If refrigerant recovery takes too long, air can be sucked in and cause pressure
increase or compressor failure, resulting in injury.
During refrigerant recovery, ensure that the liquid valve and gas valve are completely
closed and the power supply is disconnected before disconnecting the connecting
pipe.
If the compressor starts to operate when the shut-off valve is open and the
connecting pipe is not connected, the air will be drawn in and will cause the pressure
to rise or the compressor to break, resulting in injury.
When installing the unit, make sure that the connecting pipe is firmly connected
before the compressor starts to run.
Prohibit installation of the unit where there may be a leak of corrosive gas or
flammable gas.
In case of gas leaks from the unit, explosions and other accidents may occur.
Do not use extension cables for electrical connections. If the electric cable is not
long enough, please contact an authorized local service center and ask for an
appropriate electric cable.
Inadequate wiring can cause electric shock or fire.
