WINTERIZING
In areas where freezing conditions are a rare occurrence, allow the filtration system to run continuously throughout
the freeze period. Typically, during light freeze conditions, circulating (moving) water will not freeze. In areas where
freezing conditions are prevalent and sustained, the heat pump must be winterized as follows:
1) Disconnect all electrical power to the heater; turn off circulating pump.
2) At the two (2) connection unions, disconnect the plumbing to the heater (removal is counter-clockwise).
3) If your unit has an external drain plug, remove plug. This plug would be located at lower, front corner of
heater (position may vary between models). Allow water to drain out of the condenser. Replace the
winterizing plug by threading the plug in clockwise until just snug, then apply an additional 1/8 turn.
4) If no drain plug is found, unit is self draining from unions. Check online manuals for appropriate winterizing
procedures on heat pumps older than 2005.
5) To prevent insects and vermin from entering the plumbing during the winterized period, partially reconnect
the two (2) plumbing connection unions: couple each union one or two threads; this will permit condensation
to drain, but will prevent most insects and animals from entering the plumbing circuit.
START UP
To ready a winterized heat pump for use, simply retighten plumbing connection unions. Hand-tight is generally
sufficient.
Step 1: Select the "POOL / SPA" button to choose the thermostat to adjust.
Step 2: Select the "UP" or "DOWN" button to increase or decrease the desired set temperature.
Step 3: Once set, the current water temperature will be displayed. The Heat Pump will start to operate to meet
the desired temperature. Please note a time delay will be experienced if Heat Pump has just been
initialized. This delay is between 4 to 5 minutes.
Step 1: Confirm Heat Pump has power.
Step 2: Select the "MODE" button.
Step 2: Using the "UP" or "DOWN" arrow, select "ACH", "COO", "HEA", or "OFF". See section on Display for
"MODE" usage.
Step 1: Select the "MODE" button.
Step 2: Using the "UP" or "DOWN" arrow, select "OFF"
Please note – setting temperature below 45° F will also turn off Heat Pump.
Step 1: Select and hold down both the "UP" and "DOWN" arrow keys simultaneously until the Celsius /
Fahrenheit code (CF1) appears on the display.
Step 2: Select the "UP" or "DOWN" arrow to select "1" for Fahrenheit or "2" for Celsius.
Step 3: Allow display to time-out.
Select the "POOL / SPA" button.
