Cleaning the Unit
1. To ensure optimum performance, the unit
should be inspected every 6 months for build up
of dust or debri and washed every 12 months or
at periods determined by the level of
contamination experienced and according to the
following procedure.
2. Isolate the mains power supply.
3. Undo the four securing screws and remove
the connection spigot plate (Fig. 10).
4. Slide out the heat exchanger (Fig 10). The
heat exchanger should be washed in warm
soapy water and dry thoroughly.
5. Reassemble in reverse order ensuring the
heat exchanger is seated correctly.
6. Switch power supply on and check the
operation of the unit.
NOTE:
In heavy polluted internal
environments it is recommended that internal
grilles are fitted with simple washable filters
(ESG150). These filters should be removed
and washed on a regular basis (1-3 months)
or as conditions dictate.
