Steps

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”, “COOL”, “HEAT”, 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.

SECTION 4 - MAINTENANCE

POOL CHEMISTRY

Maintain pool water with the following chemical levels. Commercial applications may vary from depending on locale. All values show in PPM (Parts Per Million).

Chemical	Pool	Spa
Chlorine	1 to 3 parts per million (PPM)	1.5 to 3 PPM
Bromine	1 to 3 PPM	3 to 5 PPM
pH	7.4 to 7.8 PPM	7.2 to 7.8 PPM
Total Alkalinity	80 to 140 PPM	80 to 120 PPM
Calcium Hardness	200 to 400 PPM	200 to 400 PPM
Total Dissolved	1,000 to 2,000 PPM	1,500 to 2,000 PPM

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.
