Ice Forming on the Heat Pump
Ice Forming on the Heat Pump
ISSUE
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.
RESOLUTION
Heat Only Units:
l
The heat pump may develop a fine layer of white frost on the outside coil before entering the defrost
mode. This is normal.
l
See " Displays Defrosting " on page 60.
l
If heavy ice (not frost) starts to build up, shut off the heat pump. Contact the installer or manufacturer.
l
If the ambient air temperature will be falling below 32° F (0° C) for more than 8 hours, winterize
equipment.
"Pool / Spa" Button Will Not Work
ISSUE
The "Pool / Spa" button is disabled if the following devices have been configured on the heat pump.
RESOLUTION
l
A 2-wire external controller.
l
A 3-wire external controller.
l
An external flow switch.
Water Coming From Heat Pump
ISSUE
The water may be normal condensation produced as a by-product of the heat pump's refrigeration
process.
The heat pump can produce up to 8 to 10 gallons (30 to 38 liters) of condensation per hour depending on
the humidity of the ambient air. Determine if the water is condensation or a possible leak.
RESOLUTION
1. Deactivate heat pump, leaving the filter pump on. After several hours, determine if the 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.
