LOCATION
The unit can be installed outside (if an outdoor kit installation has been ordered). If this is installed, air entry and exit ducts should
be fitted. The indoor unit should be assembled on bases that have been prepared beforehand. It should stand on absorbent and
anti-vibration material to avoid vibrations being transmitted to the structure of the building.
Always to be done through a common duct or plenum.

4.- MAINTENANCE
4.1.- PREVENTIVE MAINTENANCE
PREVENTIVE MAINTENANCE HELPS TO AVOID COSTLY REPAIRS, SO PERIODIC INSPECTIONS ARE REQUIRED:
GENERAL CONDITION OF THE HOUSING:
Fittings, paintwork, damage from knocks, rust spots, levelling and supporting, condition of the shock absorbers, if installed,
bolted on panels, etc.
- ELECTRICAL CONNECTIONS:
Condition of hoses, tightness of screws, earthing, current draw of the compressor and fans and checking that the unit is receiving
the correct voltage.
- COOLING CIRCUIT:
Check that pressure values are correct and that there are no leaks. Check that there is no damage to the pipe insulation,
that the state of the batteries is correct and that there are no material clogging the duct and obstructing the air flow, etc.
- DRAINS:
Check that water drains correctly and that the drain trays are clean.
- FAN:
Check that fans turn freely and in the correct direction without excessive noises.
- AIR FILTER :
The air filter can be removed through the side by sliding it over the rail or downwards.
(See figure).
For downwards removal, remove the two profiles that support it (depending on the model)
which are under the filter guide rail and screwed onto the unit.
The filter should be cleaned with a vacuum cleaner or washed in soapy water.
The frequency for cleaning or changing the air filters will depend on the quality air in the area (fumes, vapors, suspended dust
particles, etc.).
Remember that the metal grille should always be toward the inside of the unit.
Remember that the Control Panel may program a notification parameter, for cleaning or replacement of air filters depen-
ding on the number of hours of fan operation in the indoor section.
