Owner Inspection

Pentair recommends that you inspect your heat
pump on a continual basis and especially after
abnormal weather conditions. The following basic
guidelines are suggested for your inspection:
1. Make sure the front of the unit is accessible
for future service.
2. Keep the top and surrounding areas of the
heat pump clear of all debris.
3. Keep all plants and shrubs trimmed and away
from the heat pump.
4. Keep lawn sprinkler heads from spraying
on the heat pump to prevent corrosion and
damage.
5. If the unit is installed under a roof edge, install
a gutter or diverter to prevent excessive water
and debris from pouring down into the unit.
6. Do not use this heat pump if any part has
been under water. Immediately call a qualified
professional technician to inspect the heat
pump and replace any part of the control
system which has been submerged.
The heat pump will produce condensation
(water) while in operation. The heat pump base is
designed to allow the condensation to exit through
the bottom drain port when the unit is running.
The condensation will increase as the outdoor
air humidity level increases. Check the following
at regular intervals to ensure proper condensate
drainage:
1. Visually inspect and clear the bottom drain
ports of any debris that could clog the ports.
2. Keep the top air flow discharge and air flow
intake area clear of debris so the air flow
though the heat pump is not restricted. The
cooler discharge air from the top should not
accumulate and be drawn into the side air
intake coils.
3. Be sure the condensate run-off is properly
directed away from the equipment pad to keep
it from undermining the pad.
4. Be sure the condensate water does not
puddle inside the heat pump. To be sure it is
condensate water, check for the absence of
chlorine.
During normal operation, the heat pump
produces three to five gallons of condensate
per hour. If condensate drainage is above this
range during operation or if water continues
to drain from the base when the heat pump is
not in operation for more than an hour, a leak
in the internal plumbing may have occurred.
Call a qualified heat pump technician to
investigate the problem.

Professional Maintenance and Service

The maximum heat output and efficiency of a heat pump is
dependent upon the quality and performance of the major
components used. Equally important are the environmental
conditions (for example, air temperature, humidity, water
temperature, and wind).
To maintain maximum performance and efficiency, keep
the air coil clean from dirt and debris. It is recommended
to clean your air coil once a year by flushing the coil with
compressed air or hosing off the coil with a garden hose.
Care should be taken to not bend the coil fins as this will
restrict the airflow and lower your heat pump performance.
Compressed air can also damage the heat pump coil. DO
NOT USE A PRESSURE CLEANER ON THE UNIT.
The heat pump should be maintained at least once a year by qualified personnel to maintain maximum performance
and efficiency. The unit should be powered off during
maintenance.
