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 POL or SPA and set your desired water temperature by scrolling either up or
down.
•
If your programmed water temperature is above the actual water temperature, the fan and
compressor will start once the time delay is satisfied.
NOTE: Each time the compressor turns off; it is protected by a 5 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.
Evaporation accounts for about 70 percent of pool heat loss, the beneficial effect of using a
pool cover or 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 the
obstructions to take the maximum advantage of their effectiveness as windbreaks, without
shading the pool surface from the sun.
