If the supply cable is damaged, it must be replaced by the manufacturer, by a service
agent or a similar qualified person.

7. Cleaning, Maintenance and Storage

Regularly wipe the enclosure using a soft sponge or cloth. For very dirty parts, use a sponge wetted
with lukewarm water and a mild detergent, then dry using a clean cloth.
Keep air inlet and fan free from dust and dirt. To clean inner parts, gently blow compressed air through
air inlet.
Regularly inspect the power cable: if worn, cracked or damaged have it replaced by technical service.
Before storing the heater, make sure it is perfectly cool and dry. Cover the unit with a plastic bag, put it
in its packing box and store it in a dry, ventilated place.
Before starting any maintenance task, shut down, unplug and let the heater cool down
for at least 15 minutes.
Do not attempt any electrical repair yourself. If the heater needs service or repair,
contact a qualified technician.
Do not use a faulty unit unless a qualified technician has inspected and repaired it.
When cleaning, make sure that water does not enter the unit.
Do not open the enclosure to clean the inner parts. Do not spray water into the heater.
Never use solvents, gasoline, toluene and similar aggressive chemicals to clean the
heater.
The following checks BY QUALIFIED PERSONNEL ONLY are recommended before every
seasonal use:
Nozzle

dirt. Replace nozzle if necessary.
Air Filters
