8 MAINTENANCE
For safety reasons, before carrying out any maintenance or
cleaning jobs, turn off the unit by moving the fan speed se-
lector to “Off” and putting off the main switch (0 position).
DANGER!
Due caution must be taken while carrying out
maintenance: some metal parts may cause injuries; wear
protective gloves.
The maintenance requirements of FWB-C ducted units are lim-
ited to periodic cleaning of the air filter and heat exchanger and
checks on the efficiency of condensate drainage.
Maintenance may be performed only by specialised
personnel.
Whenever starting up the unit after it has not been used for a
long time, check that there is no air in the heat exchanger.
The motor requires no maintenance since it has self-lubricating
bearings.
CLEANING THE AIR FILTER
Disconnect the unit from the power supply by setting the main
switch on 0 (OFF).
To clean the air filter proceed as follows:
1.
Access the unit via the inspection panel and take out the air
filter as shown in figure ( p. 141).
2.
If the filter is on the inside of the intake grille, remove the
latter and then proceed to carry out the steps described
below.
3.
Clean the filter with warm water or, in the event of dry dust
build-up, using compressed air.
4.
Allow the filter to dry and then fit it back in place.
Air filter dimensions, see figure: p. 88.
CLEANING THE HEAT EXCHANGER
It It is advisable to check the condition of the exchanger before
the start of every summer season to make sure that the fins are
not obstructed by dirt.
To access the heat exchanger, remove the outlet panel (whether
of the type with collars or a rectangular flange) and the drip tray.
On reaching the exchanger, clean it with compressed air or
low-pressure steam taking care not to damage the fins.
Before the start of every summer season, check the efficiency of
condensate drainage.
Adequate periodic maintenance will ensure save both ener-
gy and cost savings.
