Cleaning and maintenance of the fan motor

Must be carried out according to the separate instructions for the fan motor.

Cleaning of the water coil

For optimum performance, the fan heater must be cleaned regularly.

The interval between each cleaning depends on the environment the fan heater is used in.

Dust on the water battery’s aluminium fins impedes the airflow and its heat exchanging performance.

The coil must therefore be kept clean.

Important!

Do not forget to reinstall the lock washer and lock nut for equipotential bonding in the plate,

following the completed maintenance procedure.
