VIII. Summer Shutdown
If you do not plan to use the pool heat pump during the summer months, secure and protect it as follows:
1.From the control panel, turn the control switch to Remote (OFF).
2.Turn the heat pump power switch to OFF.
3.Leave the valves set the way they are unless additional circulation is required. DO NOT stop all flow through the heat pump.
4.IMPORTANT: Remember to reset the valves before the next heating season, or the heat pump will not operate properly.
IX. Freeze Protection
If the pool 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 remove the internal drain plug. Use air pressure to remove water from the bypass assembly and heat exchanger.
4.Leave the drains open until the unit is started in the spring.
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 would have to be drained anyway, or freeze damage could result.
X. Maintenance
The following maintenance procedures are designed to keep your heat pump operating at a high level of reliability. Maintenance should be performed on a periodic basis to prevent system failures and performance degradation.
A. Air Coil Cleaning - Efficient system operation depends on free circulation of air through the thin and

WARNING
Shut OFF electricity to the heat pump.
