MAINTENANCE
The maintenance operations to be carried out regularly on S80 series fan heaters
principally concern the heat exchanger which must be cleaned of dust residues,
which tend to obstruct the channels between the fins and reduce the amount of
heat exchanged.
The operation can be performed with compressed air jets.
If there are grease deposits, the fins can be washed. Take care not to wet the
electric motor and dry the finned unit thoroughly before starting the fan heater.
It is advisable to perform these operations at least once a year before the
beginning of the period when heating is required.
The electric motor does not requires maintenance as it is of the enclosed type with
self-lubricating bearings.
Each time the machine is turned on after being idle for a long period, ensure there
is no air in the heat exchanger.
It is necessary to be careful during maintenance operations: some metal parts
can cause injuries; wear protective gloves.
Maintenance may only be carried out by qualified personnel: contact your dealer
or installer.
For safety reasons, before performing any cleaning or maintenance operations,
turn off the unit by cutting the power by means of the mains switch.
