Cleaning the Unit
In addition to removing odours, providing fresh
air and recovering heat, this unit extracts
airborne impurities such as dust, dirt and
grease. These gradually build up and detract
from the efficiency and appearance of the unit.
To ensure optimum performance, the unit
should be cleaned every three to six months or
at periods determined by the level of
contamination experienced, and according to
the following procedure.
1. Isolate the mains power supply.
2. Remove the four securing screws from either
end of the cover.
3. Remove the cover.
4. Remove the heat exchanger from the unit.
5. Wash the heat exchanger in warm water
using a mild detergent and dry thoroughly.
Keep water away from all electrical components
and wiring within the unit.
If the filter cannot be cleaned, replacement is
recommended.
6. Reassemble in reverse order. The heat
exchanger should be repositioned with the ‘Top’
label facing the front and pointing upwards.
