MAINTENANCE
For safety reasons before carrying out any maintenance or cleaning opera-
tion, switch off the unit turning the selection switch to "Stop" and the power
supply switch on position 0 (OFF).
Be careful during any maintenance operation; you could get injured by some
metal parts; use protective gloves.
The fan coils FC/NT do no 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 FC/NT 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 them.
