C. PLUMBING & WATER CONNECTIONS
8. PLUMBING & WATER CONNECTIONS FOR ABOVE OR BELOW WATER LEVEL
If you install the heat pump above or below the pool or spa water level by more than 3 feet, the internal
water pressure switch may be effected by the static pressure of the pool water. In some cases it
may be necessary to eliminate the internal water "PRESSURE" switch and install a water "FLOW"
switch. The water flow switch is not effected by changes in water pressure but only water movement.
We suggest installing a 2", Grid Brand Model 20 flow switch and disabling the internal water pressure
switch. Plumb in the flow switch as shown here. Then run a TWO wire insulated cable from the flow
switch into the heater and attach to the existing water pressure switch leads located on the heater's
logic board, behind the low voltage service panel and wire as shown below.

D. WINTERIZING PROCEDURES
1. LIGHT-FREEZE CONDITIONS
(Air temperature does not remain below 32ºf for more than 4-hours)
In the event your heater will not be used for an extended period, it is recommended pool water
be allowed to circulate through the heater during normally scheduled filtration cycles. If light
freeze conditions are expected, adjust water pump controls for continuous operation throughout
the light freeze episode. Moving water will not freeze under light-freeze conditions. Remain
aware of abnormal climatic conditions; use "hard-freeze" instructions
(Below) if freezing conditions will exceed 4-hours.
FAILURE TO PROPERLY WINTERIZE HEAT PUMP MAY RESULT IN SERIOUS
EQUIPMENT DAMAGE. FREEZE DAMAGE IS NOT COVERED UNDER THE
HEAT PUMP WARRANTY. FAILURE TO HEED THE FOLLOWING CAN RESULT IN
DAMAGE TO EQUIPMENT AND/OR PROPERTY.
