DANGER!
Due caution must be taken while carrying out
maintenance: some metal parts may cause injuries; wear
protective gloves.
B
ATTENTION: maintenance may be performed exclusively
by specialised personnel. If any work needs to be done on
a unit that is working with hot water, it is advisable to shut
off the hot water (by means of the on-off valves) and allow
the fan to run for a few minutes until all the metal parts have

long time, check that there is no air in the heat exchanger.
The electric motor requires no maintenance since it has self-lu-
bricating bearings.
The routine maintenance operations to be performed on fan
heaters mainly concern the heat exchanger. It must be cleaned
to eliminate dust build-up, which tends to obstruct the spaces
between the fins, resulting in a decrease in the quantity of heat
exchanged.
This job may be done using jets of compressed air.
If grease has also deposited you can wash the fins, taking care
not to wet the electric motor and making sure the finned block
is thoroughly dried before starting the fan heater.

NOTE:
It is recommended to carry out these operations at
least once a year before the start of the heating season.
