Maintenance
Ecotec Heat Pumps are designed for long life and
trouble free operation if installed and maintained
properly.
Make routine checks throughout the year to see
that the intake vents are not obstructed by snow,
ice or leaves. Clear snow or ice from the fan grill,
intake vents and from below the unit.
Cleaning
Care should be taken to keep the fins (evaporator
coil) and fan blades clean. Clean fin surfaces will
result in higher system performance and energy
efficiency.
Cleaning should be done every (6) months in
areas with poor air quality (high particulate
value).
Cleaning should be done every (12) months in
normal air quality environments.
Clean units using mild detergent and water.
Take
care not to damage or bend evaporator coils while
cleaning.
Care should be taken to keep the drain holes at the
base of the unit free of debris to ensure proper
condensate drainage. A drainage channel below
the drain holes is recommended to prevent
condensation build up around the base of the unit.
For sea side installation extra attention must be
given to cleaning the units to remove salt buildup
which will cause rusting. For high corrosive
environments we recommend
Marine Grade Heat
Pumps
which are specially designed for salt spray
environments.
(Marine Grade Heat Pumps are available as a
special order).
Risk of freezing
N
ote that the heat exchanger is located outdoors,
which involves a risk of freezing in the event of a
power failure.
Drain the heat exchanger when a power
failure longer than one hour in low
temperatures occurs (-1
C or lower).
The circulation pump must
never stop
when
the heat pump is running.
The circulation pump must operate even
when the heat pump has been stopped in
cold weather to prevent water from freezing
in pipes.
