Maintenance
IMPORTANT
BEFORE CARRYING OUT MAINTENANCE OR CLEANING OPERATIONS MAKE SURE THE UNIT POWER SUPPLY IS DIS-
CONNECTED. ANY ORDINARY OR EXTRAORDINARY MAINTENANCE OPERATION MUST BE CARRIED OUT BY SPECIA-
LIZED AND AUTHORIZED PERSONNEL IN ORDER TO ENSURE COMPLIANCE WITH THE SAFETY REGULATIONS IN
FORCE.
N.B.
The unit switch on button placed on the frontal panel of the unit do NOT exclude the electrical voltage to all the circuits
contained inside the electrical panel of the unit. Always make sure that the power supply lines (of the heat pump and of
the integrative electrical heaters) are disconnected at the start before carrying out any maintenance operation.
This section is extremely important for the efficient operation of the unit during the years. A few operations carried out periodi-
cally can avoid the need to call specialized personnel. The operations to be carried out do not require particular technical kno-
wledge and consist of simple checks of the components of the unit.
Contact an authorized service center if maintenance is required.
Structure
To prevent noises and strange vibrations to rise make sure that the various steel parts are well fastened together and that the
inspection panels are properly fixed to the unit.
In case of oxidation, treat with paints, suitable to avoid or reduce the problem, the parts of the unit affected.
Hydraulic plant
Visually check that the hydraulic plant is leaks free and is pressurized. Verify there is no air in the circuit (acting on the air vents).
Verify that the filters in the plant are clean.
Electrical plant
Verify that the power supply cable that connects the unit to the distribution panel is not affected by cuts, cracks or alterations that
could compromise the insulation. Contact an authorized service center if maintenance is required. After a first period of time from
the first start up and at every stop or seasonal start up carefully check that each electrical connection is well fixed.
