SERVICING
Routine servicing
- To ensure the correct operation of the ins-
tallation, it is necessary to have preventive
maintenance of the indoor and outdoor units
carried out by qualified personnel.
General installation
- Carry out a visual inspection of the complete
installation in service.
- Check the general cleanness of the instal-
lation, and check that the condensate
evacuations are not blocked, particularly on
the indoor unit, before the summer season.
- Check the condition of the tray.
OUTDOOR UNIT
Coolant system
- Clean the heat exchanger using a special
product for aluminium-copper heat
exchangers, and rinse with water. Do not use
hot water or steam, as this could cause the
pressure of the coolant to increase.
- Check that the surface of the aluminium fins
of the heat exchanger is not damaged by
impacts or scratches, and clean with an
appropriate tool if necessary.
Electrical section
- Check that the main power supply cable is
not damaged or altered in such a way as to
affect the insulation
- Check that the interconnecting cables
between the two units are not damaged or
altered, and that they are correctly
connected.
- Check the earth connection.
INDOOR UNIT
- In order for the installation to operate
correctly, it is essential to regularly clean the
air filter located in the intake of the indoor
unit.
- When clogged, the filter reduces the air flow
through the heat exchanger of the indoor
unit, which in turn reduces the efficiency of
the installation and inhibits the cooling of the
fan motor.
- Check the cleanness of the indoor heat
exchanger.
CAUTION
BEFORE CARRYING OUT ANY OPERA-
TION ON THE EQUIPMENT, CHECK
THAT THE ELECTRICAL POWER
SUPPLY IS SWITCHED OFF AND THAT
IT CANNOT BE SWITCHED ON
INADVERTENTLY.
