PUTTING IT INTO SERVICE
PUTTING IT INTO SERVICE
3�1 Preliminary warnings
The initial start-up of the heat pump must be carried out
by the Service Centre.
The customer must be present when the appliance is test-
ed and informed of the contents of the manual and proce-
dures. After commissioning, the manual and the warranty
certificate must be handed over to the customer.
Before start-up, all work (electrical and plumbing connec-
tions, filling and venting of air from the plant) must be
completed.
Remove any dirt or debris from the inside of the appliance,
especially chips, wire pieces and screws.
Make sure that:
• all safety conditions have been met
• the unit has been properly secured to the supporting sur-
face or wall
• the minimum technical clearances have been respected
• the hydraulic connections have been made according to
the instructions in the manual
• the hydraulic plant has been filled and vented
• the shut-off valves of the hydraulic circuit are open
• the general power supply cables are of a suitable
cross-section area, capable of supporting the overall draw
of the unit
• the earthing was performed correctly
• the electrical connections have been established correctly
• all electrical connections are properly secured and all ter-
minals properly tightened
• the voltage is within a tolerance of 10% of the rated volt-
age of the unit
• the power supply of the three-phase models has a maxi-
mum unbalance between phases of 3%
• all control wires are connected and all electrical connec-
tions are firmly in place
• the mesh filter is installed and clean
Operating the unit without the water filter installed and
clean is forbidden.
Preliminary warnings for R32
The unit uses environmentally friendly R32 refrigerant gas,
with a Global Warming Potential (GWP) = 650. Do not re-
lease R32 gas into the atmosphere.
R32 refrigerant gas is slightly flammable and odourless.
Do not place flammable objects (spray cans) within 1 me-
tre of the air outlet.
All precautions concerning the treatment of the refriger-
ant must be observed following the regulations in force.
Avoid proximity to sources of ignition in continuous oper-
ation (open flames, gas appliances, electric stoves, lighted
cigarettes, etc.).
Do not use any means to speed up the defrosting process.
Smoking in the vicinity of the appliance is prohibited.
Using a mobile phone near the appliance is prohibited.
Perform the following checks:
• carry out safety checks to ensure that the risk of combus-
tion is minimised
• avoid working in confined spaces
• delimit the area around the workspace
• ensure safe working conditions around the area by con-
trolling flammable material
Leak detection
The use of combustion fluid detectors, e.g. a halide torch
or other detection system using an open flame, is forbid-
den.
Follow the instructions below for leak detection:
• use electronic detectors to detect flammable refrigerants
• check that the detectors are properly calibrated before
use
• calibration operations must be carried out in an area free
from refrigerant
• make sure that the detector is not a potential source of
combustion and that it is suitable for the refrigerant used
• all open flames must be removed if a leak is suspected
• in the event of a leak requiring brazing, it is mandatory
to recover all the refrigerant from the system or isolate it
(by means of shut-off valves) in a part of the system away
from the leak
The use of silicone sealant may affect the effectiveness of
some types of leak detectors.
