Ice Forming on the Heat Pump
When conditions are too cold for proper operation, the heat pump will enter a defrost mode. This
prevents ice from building up on the evaporator coil.
Heat and Cool Units (with Active Defrost or "Icebreaker"):
During freezing conditions, pool or spa heating will continue. Frost or ice may develop during the
l
"countdown" to the active defrost (up to 50 minutes). This is normal.
The heat pump will enter an "active defrost" stage to remove the accumulated frost and ice.
l
n During the active defrost period, the pool or spa will stop heating.
n Observe the heat pump after its active defrost cycle. If ice or frost remains when the unit goes back to
heating, deactivate the unit and call for service.
If the ambient air temperature is (or will be) falling below 32° F for more than 8 hours, winterize
l
equipment.
Water Coming From Heat Pump
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.
1. Deactivate heat pump, leaving the filter pump on. After several hours, determine if water is still coming from
the heat pump.
2. If using chlorine or bromine as a pool / spa sanitizer, test the water around the heat pump using a test strip. If
the test strip indicates that chlorine or bromine is present, a leak may exist.
PLEASE NOTE -
If desired, a kit is available to re-direct condensation water away from the heat pump.
See "Condensation Drain Kit (# STK0202)" on page 19.
