MAINTENANCE

For safety reasons before carrying out any maintenance or cleaning operation,
switch off the unit turning the speed selection switch to "Stop" and the power
supply switch to 0 (OFF).
Be careful during any maintenance operation: you could get injured by some
metal parts therefore use protective gloves.
The fan coils FA 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 fan coils FA 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 conditions, check that:
- condensate drainage is performed correctly:
- the heat-exchanger fins are not obstructed by deposits of dirt. If necessary clean
the unit with low pressure compressed air or steam without damaging the fins.
9 CLEANING
For safety reasons before carrying out any maintenance or cleaning operation
switch off the unit turning the speed selection switch to "Stop" and the power
supply switch to 0 (OFF).
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:
- remove the air filter as shown in figure 6 page 19;
- clean the filter with lukewarm water , or in case of dry dust, with compressed air;
- reassemble the filter after having dried it up.

the 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 and damage
