SERVICING AND MAINTENANCE.
WARNING:
THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED
FROM THE POWER SUPPLY DURING MAINTENANCE.
1. At intervals appropriate to the installation, the fan should be inspected and cleaned to ensure there is no build
up of dirt or other deposits.
2. Remove the Indoor Grille (See Section A : 2 for instructions) and wash in warm soapy water.
3. Wipe the shutter blades with a damp cloth until clean.
4. Replace the Grille.
The LoWatt fan has sealed for life bearings, which do not require lubrication.
