Maintenance

Clean the casing and the grill of the indoor unit either with
a vacuum cleaner or a rag soaked in a soft liquid detergent.
Do not use water to clean the indoor unit. Water may damage the internal
components and cause electrical discharges.
Filling the drainage siphon
So as to avoid having problems with the condensed water, we
recommend that, prior to start up and before the beginning of
each season, the drainage siphon be filled with water so as
to avoid air being sucked in through this tubing.
Discharge of the indoor units with ducts
The discharge of the indoor units equipped for ducts are
supplied without a protecting grill. When carrying out
maintenance services, keep this in mind.
In the case of installing an indoor unit with free discharge and equipped for
ducts, the outlet opening should be protected with a grill. The lack of this
protection could provoke damage caused by the fan turbine.
Cleaning the filters
14
CAUTION
Keep the battery filters in good condition, checking them at
least once a month. If the filters are dirty, air flow and
equipment performance are reduced.
Cleaning the outdoor unit
Dirt should not be allowed to accumulate in the outdoor
battery. It should be cleaned as frequently as needed,
with a brush, vacuum cleaner or detergent.
For safety reasons, make sure to turn the air conditioner off, and unplug
the power supply, prior to cleaning.
Check the outdoor unit periodically to see if the air inlet or outlet are
clogged by dirt or leaves, etc.
The internal coil and other components of the outdoor unit must also be
periodically cleaned. Contact your concessionary or maintenance service.
Checking the tension of the belts
The tension and wear of the belts of the motors should be
checked, and the belts changed if necessary. Before
carrying this operation out, disconnect the main supply
switch.
For safety reasons, make sure to turn the air conditioner off, and unplug
the power supply, prior to checking the fan motor belts.
