Cleaning
In order to perform at its peak, the fan heater must be cleaned regularly.
Dust on the water coil’s aluminium fins reduces airflow and its heat exchanging performance.
The coil must therefore be kept clean, which can be done in one of the following ways:
1. Blowing with compressed air.
2. Steam cleaning.
3. Spraying or rinsing with water. If the fins are greasy, add a suitable detergent.
For options 2 and 3, the fan motor must be protected against the ingress of water. When cleaning, the fan heater
must be disconnected from the power supply, and the air deflector grille and cleaning cover removed.
Also clean the fan protective grille and the fan blades with a soft brush.
The interval between each cleaning depends on the environment the fan heater is used in.
