CLEANING

Your heater needs very little maintenance, but the following information will help you to keep it looking good and
working efficiently. All parts of the heater can be cleaned using a soft, damp cloth.
DO NOT attempt to clean the heater while the appliance is hot or operating.
DO NOT use solvents or abrasives to clean any parts.
WARNING
DO NOT spray aerosols in the vicinity of the heater whilst in operation.
DO NOT place articles on or against this heater.
DO NOT store flammable materials near this heater.
DO NOT remove any panels or attempt to carry out any service work other than that which is
mentioned in the Trouble Shooting Checklist "Trouble Shooting Checklist" on page 14.

Filters

The filters for this appliance are fixed to the inlets of the room air return. The build up of dust or other particles on
these filters reduces the air flow through the heater, reducing the efficiency, which can cause the appliance to shut
down. To stop this from occurring the filters will need regular cleaning.
Clean the filters with either a vacuum cleaner, a soft dry cloth, or a soft brush. NEVER attempt to clean filters with
water.

Filter blockages

When a build up is detected the blockage LED, located by the infra-red remote receiver window, will begin the
flash. Once the indicator is flashing, if no action is taken, the heater will shutdown to avoid overheating and error
code 14 will be displayed in the error display window.
