vii. ROUTINE MAINTENANCE
The ceiling assembly and the outside shroud
can be cleaned with a damp cloth. When
required, a mild detergent can be used.
Filters are made from long life non-allergenic
natural fibers which can be cleaned and
reused, and completely filter the circulated air
when the heat pump is in operation. If the
filters are not cleaned at regular intervals, they
may become partially clogged with lint, dirt,
grease, etc. A clogged filter will produce a loss
of air volume and may eventually cause an
icing-up of the cooling (evaporator) coil.
Cleaning and/or changing the filters:
1. Remove the two grilles from the ceiling
assembly by pulling the tabs on the grilles as
shown in the illustration.
2. Remove and clean or replace the two
filters. The filters should be washed in warm
water or vacuumed clean. The filters should
be inspected once a month and cleaned or
replaced as needed.
3. Re-install the filters and grilles in the ceiling
assembly.
IMPORTANT: Do not operate your heat pump
for extended periods of time without the filter
installed.
An even more serious condition occurs when
the heat pump is operated without a filter.
When this happens, the lint, grease, etc. that
are normally stopped by the filter are now
accumulating in the cooling coil. This not only
leads to a loss of air volume and a possible
icing-up of the cooling coil, but could, also,
result in serious damage to the operating
components of the heat pump.
NOTE: If the unit is operated in a dusty
environment, the filters should be inspected
and cleaned more frequently
