AINTENANCE AND CLEANING
For safety reasons before carrying out any maintenance or cleaning
operation, switch off the unit turning the selection switch to "Stop"
and the power supply switch on position 0 (OFF).
Maintenance
Be careful during any maintenance operation; you could get injured
by some metal parts; use protective gloves.
The units do not require any particular maintenance operation: only
the periodical cleaning of the air filter should be carried out.
It is necessary to carry out a running in period of 100 hours in order
to eliminate all mechanical friction.
The starting up must be carried out at the maximum speed.
For good operation of the units follow the instructions below:
■ keep the air filter clean;
■ do not pour liquids into the unit;
■ do not introduce metal parts through the air outlet grill.
■ keep the air inlet and outlet free at all times.
Each time the machine is turned on after being idle for a long
period, ensure there is no air in the heat exchanger.
Before using the unit for air conditioning, check that:
■ condensate drainage is performed correctly:
■ the heat exchanger fins are not obstructed by deposits of dirt.
If necessary clean the fins with low pressure compressed air
or steam without damaging the fins.
Cleaning
Clean the filter at least once a month and in any case before using
the unit (before the heating or the air conditioning season).
For cleaning the air filter proceed as follows (figure 7)
■
model FWV
turn the screws that secure the filter to the cover cabinet 90° and
remove the filter,
■
model FWL
remove the air filters that are inside the intake grids located on
the front panel of the cover cabinet,
■
concealed model FWM
reach the unit through the inspection panel and remove the filter,
turning the locking brackets 90°,
■
clean the filter with lukewarm water, or in case of dry dust, clean
the filter with compressed air,
■
reassemble the filter after having it dried up.
It is recommended to replace the air filter yearly, and to use original
spare parts. The unit model name is stated on the nameplate located
on the side panel of the basic unit.
To clean the unit cabinet proceed as follows:
■ use a soft cloth;
■ do not pour any liquid on the unit, as this could cause
electrical shocks or damage the components inside it;
■ do not use any aggressive chemical solvents; do not use
very hot water to clean the air outlet grill.
