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 fl ow, 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 fi lter can be removed through the side by sliding it over the rail or downwards.
(See fi gure).
For downwards removal, remove the two profi les that support it (depending on the model)
which are under the fi lter guide rail and screwed onto the unit.
The fi lter should be cleaned with a vacuum cleaner or washed in soapy water.
The frequency for cleaning or changing the air fi lters 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.
SIDE REMOVAL
Remember that the Control Panel may program a notifi cation parameter, for cleaning or replacement of air fi lters depen-
ding on the number of hours of fan operation in the indoor section.

4.2.- FAULT DIAGNOSIS
DIRTY FILTER INDICATION
If the fi lters are dirty, the detector activates an alarm, but only if the fan is ON.
SMOKE DETECTOR
In this case it would initiate shutdown sequence the unit, fully close the return air damper and open the fresh air dam-
per up to 100% and send an alarm signal to the unit.
All the components derived from the recycling of the unit should be managed according local legislation, and have to be
classifi ed and separated while dealt by authorized waste manager or be left in local waste facilities.
Refrigerant fl uids, electronic boards, heat exchangers and the oil extracted from the refrigerant circuit, as well as the
oil recipients used must be recycled as hazardous waste according the local normative through an authorized waste
manager or be left in local waste facilities. The rest of the components considered as non-hazardous wastes must be
recycled according to the corresponding norms.
At the end of its life, the equipment should be recycled in local waste facilities or by an authorized waste manager.
