The water may be normal condensation produced as a by-product of the heat pump's refrigeration process.
The heat pump can produce 8 to 10 gallons of condensation per day depending on the humidity of the ambient
air. Determine if the water is condensation or a possible leak.
Ice Forming on the Heat Pump
Why ice and frost appear:
1. When the heat pump operates, air is pulled into the unit and across the cold air coil.
2. As heat is removed from the air, moisture in the air will condense on the surface of the air coil (condensation).
3. Depending on the humidity level, when air temperatures are below 50°F this condensate can begin to freeze.
Forming frost then ice.
What to expect:
l
The heating of the pool or spa water continues while frost and ice develop.
l
The heat pump is designed to periodically enter a “defrost” stage to remove the accumulated frost and ice.
l
During the “defrost” stage, pool or spa heating is suspended till the end of the “defrost” cycle.
Troubleshooting:
1. The heat pump can be more efficient if used during warmer parts of the day. This heat gain can be retained during
the colder parts of the day by using a pool blanket.
2. If the heat pump forms sheets of ice that never go away during a cold season, conditions may not allow for proper
heat transfer. And the heat pump should be turned off.
3. If the ambient air temperature is warm and ice is appearing on the heat pump, turn off the heat pump. Service may
be required.
