Inspection and Service

Air Energy™ Heat Pumps are designed and
constructed to provide long performance life when
installed and operated properly under normal conditions.
Periodic inspections are important to keep your heat
pump running safely and efficiently through the years.
6.4.1

Owner Inspection

Air Energy™ recommends that you inspect
your heat pump on a regular basis and especially after
abnormal weather conditions. The following basic
guidelines are suggested for your inspection:
1. Keep the top and surrounding areas of the heat
pump clear of all debris.
2. Keep all plants and shrubs trimmed and away from
the heat pump.
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. Ensure that condensate water does not puddle
inside the heat pump
3. Ensure that condensate run-off is properly directed
away from the equipment pad to keep it from
undermining the pad.
During normal operation, the heat pump produces
11 to 19 liters 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.
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. Keep all plants and shrubs trimmed away
from the heat pump.
Make sure the front of the unit is accessible for
future service. Keep lawn sprinkler heads from spraying
on the heat pump to prevent corrosion and damage. Use
a deflector if needed. If the unit is installed under a very
sharp roof pitch or under a roof without a gutter, a gutter
or diverter should be fitted to prevent excessive water
from pouring down into the unit.

Professional Inspection

Inspections performed at least once a year by a
qualified technician are required to maintain your heat
pump's safe and efficient operation. The following basic
safety checks must be performed:
1. Check for loose or broken wires and terminal
connections.
2. Check for bad or welded contacts on the
contactor(s).
3. Verify the pressure switch operation. Turn the heat
pump OFF. Disconnect the power to the pump
time clock, or turn the pump time clock to an OFF
position. Turn the heat pump back ON. The heat
pump must not come on.
4. Inspect the electrical controls, specifi cally the
following:
a. High and Low limits
b. Pressure switch
c. Temperature control
5. Inspect the evaporator coil for blockage and clean
as necessary.
6. Check for spider webs or debris in the condensate
drain; clean if necessary.
7. Conduct a normal operating cycle and observe that
the unit operates properly.
