MAINTENANCE

GENERAL INSTALLATION

perform a visual inspection of the complete installation in operation.
Check the general cleanliness of the installation and check that the condensate evacuation pipes are not blocked,
particularly the evaporator coil pipe, before the summer season.
Check the condition of the condensate tray.
Check the condition and tension of the belt(s) of the indoor units if necessary.

REFRIGERANT CIRCUIT

Clean the air exchanger using a special product on the aluminium / copper pipe coils. Then rinse with water. Do
not use hot water or steam for cleaning as this could provoke a refrigerant fluid pressure rise.
Check that the aluminium fins on the heat exchanger coil have not been damaged by impacts or scratches and
clean them with an appropriate tool as required.
For the installation to operate correctly the air filter located at the level of the air treatment coil intake and on the
condenser must be cleaned regularly.
Cleaning intervals vary greatly depending on the level of impurities in the air. The filter should be replaced regularly.
A clogged filter causes a reduction in the air flowing across the heat exchangers, leading to a reduction in installation
output and hindering the cooling of the fan motor.
Check the cleanliness of the indoor coil.

ELECTRICAL CIRCUIT

Check that that the mains supply cable has not been damaged in any way that might cause a breakdown in insulation.
Retighten as required.
Check the earth connection.
Carry out the same checks on the cable(s) connecting the units.
This is not an exhaustive list. Other checks can be performed depending on the environment and the unit's operating
conditions.
BEFORE STARTING ANY WORK ON ThE UNIT, YOU MUST ENSURE ThAT ThE POWER SUPPLY IS
CUT OFF AND ThAT ThERE IS NO POSSIBILITY OF IT BEING ACCIDENTALLY
