This heater is protected with an overheat protection failsafe that switches the heater off
automatically if it senses that it is about to overheat.
An example of this would be due to total or partial obstruction of the inlet vents.
In this scenario, disconnect the mains power to the heater and wait 30 seconds for it to cool
down. Once the heater has cooled down, remove any obstruction from the inlet vents.
Switch it back on as described earlier in the manual.
After the heater has been switched on, the heater will operate normally. If the problem
persists, please contact your supplier for assistance.
Before undertaking any cleaning or maintenance on the heater, disconnect it from the power
supply.
For cleaning it is recommended to use a soft moist rag and neutral detergent. Do not use an
abrasive cloth or substances which could affect the appearance of the heater.
Check that the hot air outlet and the inlet vents are free of dust and dirt.
During cleaning, be careful not to touch the heating elements.
In case of breakdown and/or poor functioning of the heater, disconnect the heater from the
power supply and contact your supplier.
NOTE: As a result of continual improvements, the design and specification of the heater
may differ slightly to the unit illustrated on the packaging.
Ducasa heaters require very little maintenance.
The surfaces of the heater must not be cleaned with an abrasive product or those containing
granular substances. We recommend regular cleaning with PH neutral products.
In order to clean the heater, it is recommended that the electric power is switched off.
