Cleaning/maintenance.
For optimum performance, the fan heater must be cleaned regularly. The fan heater is fitted with a removable front panel for fast and easy
cleaning, see photo 10. The interval between each cleaning depends on the environment the fan heater is used in.
Dust on the fan protective grille and on the water battery’s aluminium fins impedes the airflow and reduces its heat exchanging
performance. The water battery must therefore be kept clean. The fan cooling flanges also need to be kept clean, to obtain the lowest pos-
sible motor operating temperature.
1. Disconnect the power to the fan motor.
2. The lower eccentric lock is fitted with a screw (photo 11) to prevent opening of the front panel without a tool, and access to the rotating
fan blade. May be replaced by a lock.
3. Disengage both eccentric locks and rotate the front panel outward, see photo 12.
4. The opening angle of the front panel is limited by a stop (see photo 13), to prevent the flexible hoses from breaking. This function must
not be removed or modified.
Important! In ceiling mount installations, the removable front panel must be lowered carefully and must not be subjected to any
additional loads when open.
5. The removable front panel and rear are fitted with draining plugs for removing dirt and water during cleaning, see photo 14 and 15.
Catch the water under the heater in a bucket or similar container. Punch out the plugs using a tool and reinstall them following the
completed cleaning procedure.
6. Do not forget to reinstall the screw in the lower eccentric lock following the completed cleaning procedure.
