VII. Freeze Protection
If the heat pump is installed in a location subject to freezing conditions, it is important to protect
the water circuit from freezing, just as should be done for the pump and filter.
System Drain-Down
1. Turn the heat pump circuit breaker or disconnect switch to OFF.
2. From the control panel, turn the control switch to Remote ( OFF).
3. With the pool pump OFF, close the external shutoff valves and loosen the inlet and outlet
water unions to allow water to drain. Use a Shop Vac or air pressure to remove excess water.
4. Re-attach the unions.
5. Cover the heat pump with a waterproof cover.
Continuous Pump Operation
It is also possible in some areas to prevent heat pump freeze damage by operating the pump
continuously during freezing weather. However, this results in significantly higher pump
operating cost. Further, if a sustained power failure occurs, the heat pump MUST be drained
anyway, or freeze damage could result.
VIII. Maintenance
NOTE: The heat pump MANUFACTURER IS NOT RESPONSIBLE for maintenance
adjustments.
The following maintenance procedures are designed to keep your heat pump operating at a high
level of reliability. Maintenance must be performed on a periodic basis to maintain warranty
coverage and prevent system failures and performance degradation.
A. Air Coil Cleaning - Efficient operation depends on free circulation of air through the thin and
tightly-spaced fins of the evaporator coils. The evaporator must be cleaned whenever it has a
buildup of dirt or debris.

2.
B. Cabinet Care (optional) - The cabinet is designed for outdoor use and requires little care.
However, you can clean it if you wish.

2. Wash the cabinet with soap and water.
