START-UP

Before proceeding with this section make certain all plumbing connections are airtight and leak free.

Flow rates should not exceed 70 GPM maximum. Use of an external bypass is necessary at 70 GPM

and above. Minimum flow rate is 20 GPM.

• Turn filter pump time clock to the ON position and set filter pump hours. For initial heating, the pool

heater and filter pump may need to run continuously until your desired temperature is reached. After

initial heating is achieved, the heater will run only to maintain your desired temperature.

• Turn power supply to heater ON.

• The control panel will light up and display either OFF or the actual pool water temperature.

• Select POOL or SPA and set your desired water temperature by scrolling either up or down.

• Select P_S and scroll up or down to select POOL or SPA mode.

• If your programmed water temperature is above the actual water temperature, the red HEAT ON LED will

light up indicating HEAT mode. The fan will start, and then the compressor will start.

NOTE: Each time the compressor turns off, it is protected by a 3 minute anti-cycling delay.

Initial Heating

Initial heating may require you to run your heater and filter pump continuously for at least 24 hours,

or more, depending on the following factors:

• Temperature difference between actual water temperature and desired water temperature.

• Size of pool.

• Ambient air temperature, the cooler the air temperature the longer the heating time.

• Heat loss (evaporative, convective, radiative and conductive).

• A pool cover / solar blanket may reduce initial heating time by up to 50 percent.

Reducing Heat Loss - Pool Cover / Solar Blanket

We highly recommend the use of a pool cover / solar blanket. Covering your pool is the single most cost

effective means of reducing heat costs from 50 to 70 percent. Heating a pool without a cover is like heating

a house without a roof. They also reduce the amount of maintenance costs. By reducing evaporation,

covers reduce the quantity of chemicals needed.

Because evaporation accounts for about 70 percent of pool heat loss, the beneficial effect of using a pool cover /

solar blanket can be dramatic.

Wind Speed Reduction

Reducing wind velocity at the water surface reduces convective and evaporative losses. Fences, trees, hills, or

tall hedges close to the pool perimeter are effective windbreaks. Locate these obstructions to take maximum

advantage of their effectiveness as windbreaks, without shading the pool surface from the sun.
