Spring Start-Up
If your heat pump has been winterized, perform the following steps when starting the system in the Spring:
1. Uncover the heat pump and inspect the top and sides for any debris or structural problems.
2. Connect the water inlet and outlet unions located on the lower front panel of the heat pump.
3. Turn on the filter pump to supply water to the heat pump. Open the filter air bleeder and circulate water
through the system long enough to bleed all the air out of the pool system. Check for leaks in and around
the heat pump.
4. Turn on the electrical power to the heat pump at the main breaker panel.
Inspection and Service
Pentair Water 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.
Owner Inspection
Pentair Water 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. Use a deflector
if needed.
5. 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.
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. Ensure that condensate run-off is properly directed away from the equipment pad to keep it from
undermining the pad.
4. Ensure that condensate water does not puddle inside the heat pump.
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.
