2.1 Regulation installation
and maintenance conditions
The appliance must be installed and the maintained
by an approved professional in accordance with the
prevailing regulations and code of practice, in particular:
- The legislation on the handling of refrigerants.
- Heating installation with oor heating system.
- Low voltage electrical installations - Rules.
2.2 Unpacking and reservations
2.2.1 Receipt
Carefully check, in the carrier's presence, the general
appearance of the appliances and check that the
outdoor unit is not laid on its side or back.
In the case of any dispute, state any appropriate
reservations to the carrier in writing within 48 hours and
send a copy of this letter to the After-Sales service.
2.2.2 Handling
The outdoor unit should not be laid on its side or back
during transport.
If not kept upright during transport, the appliance could
be damaged through displacement of the refrigerant
and deformation of the compressor suspension.
Any damage caused by transportation of the unit lying
down is not covered by the warranty.
If necessary the outdoor unit may be tilted only during
manual handling (to go through a door or use a staircase).
This operation must be conducted very carefully and
the appliance must be immediately restored to upright
position.
2.2.3 Containment of refrigerant circuits
All refrigerant circuits fear contamination from dust and
moisture. If such pollutants introduced into refrigeration
circuit, they can contribute to degrade the reliability of
the heat pump.
" It’s necessary to ensure correct containment
connections and refrigerant circuits (hydraulic
unit, outdoor unit).
" In case of subsequent failure and expertise, the
nding of the presence of moisture or foreign
objects into the compressor oil would lead to
systematic exclusion of warranty.
- Check upon receipt that the ttings and the refrigeration
circuit caps mounted on hydraulic unit and outdoor unit
are properly seated and locked (impossible to loosen
bare hands). If this is not the case, tighten them using
an against wrench.
- Check also that the refrigerant connections are sealed
(plastic caps or tubes crushed at the ends and soldered).
If the caps must be removed during installation (tubes
cut by example), put back them as soon as possible.
