CLEANING AND MAINTENANCE
CAUTION! Before carrying out any cleaning or maintenance work, disconnect the
unit from the mains electricity supply!
ROUTINE MAINTENANCE
The user is duty bound to have all maintenance operations carried out by trained and
qualified personnel only. If the unit has to be dismantled, protect hands with work gloves.
Monthly checks:
- Ensure that the fan impellers are clean. If they are dirty, clean them by suction so as not
to damage them.
- Check the whole of the electrical part and in particular that the electrical connections are
tight.
Yearly checks:
- Check the whole of the electrical part and in particular that the electrical connections are
tight.
- Check the tightness of all the bolts, nuts and whatever else may be loosened by the
constant vibrations of the unit.
- Check the motor for dust, dirt or other impurities. Periodically check that the motor works
without unusual vibrations or noise and that the fan inlet is not obstructed, which could
otherwise leading to overheating of the windings.
- Check the fans for dirt or any foreign matter.
CLEANING THE AIR FILTER
The unit is fitted with an air filter on the fan inlet. During normal operation the filter holds
back impurities in the air.
The filter should be cleaned periodically to keep its filtering properties and the airflow to
the fan unchanged.
It is advisable to clean the filter at least once a month, proceeding as follows.
1. Take out the filter.
2. Place the filter on a flat, dry surface and remove the accumulated dust with a vacuum
cleaner.
3. Wash the filter with water and detergent (no solvents).
4. Leave the filter to dry in a ventilated place in the sun.
5. Replace the filter when it is perfectly dry.
Please clean the air filter every working season of the unit or more frequently
considering the unit activity.
Contact a firm specialised in differentiated waste disposal; it is the only way to be certain
of correct recycling and thereby contribute to protection of the environment.

N.B.: the filter may also be taken out from the side or from the top.
WHAT TO DO IF...
There is little outflowing air?
-
Incorrect speed setting on the control panel (select the right speed).
-
Clogged filter (clean the filter)
-
Obstruction of the airflow on the intake or delivery line (remove obstruction).
The motor does not turn? Check that
-
The power supply is switched on;
-
The switches or thermostats are in the correct operating position;
-
There is no foreign matter jamming the rotation of the fan.
The unit does not heat/cool as before? Check that
-
The filter and the coil are clean;
-
No air has entered the water circuit by bleeding from the relative valve;
-
The installation is correctly balanced;
-
The boiler/chiller is in proper working order.
DISMANTLING THE UNIT
This unit is made to last for many years. Qualified personnel are needed to dismantle it
in all safety. The first operation to be carried out before dismantling the unit is to disconnect
it once and for all from the electricity supply.
This unit has been made using recyclable materials (copper, aluminium, brass, plastic)
and assembled by screws and push-fits to make separation of the parts easy.
