V. Initial Start-Up and Check
1 . Verify that the
Power
lamp is ON and that the pool/spa pump is running and circulating
properly.
2.
Verify that the control panel
Heat-Remote-Cool
switch is in the
Remote
(OFF) position; see
the figure.
3.
Turn the control switch to Heat
and
to turn the pool system ON. Raise the thermostat setting
above the current water temperature. The fan and compressor should start up and run
simultaneously.
NOTE: The heat pump will be OFF when the Remote position is selected on the Heat-Remote-Cool
selector switch and there is no remote control system attached.
4.
Allow the heat pump to operate for a few minutes to stabilize operating pressures and to
allow various component temperatures to normalize.
5.
Verify that the discharge air temperature is approximately 8° - 10° cooler than the air entering
the unit when heating.
A. Heating Mode
Whether heating or cooling, the unit is designed to operate up to 24 hours a day.
1.
Set the
Heat/Cool
switch on the control panel to
Heat
mode
2.
Rotate the thermostat control knob to the desired water temperature. Whenever the setting on
the thermostat control knob is above the actual water temperature, the fan will run.
NOTE: Whenever the unit is turned OFF, and turned back ON the fan will start but the compressor will not
restart for approximately 5 minutes. This delay protects the compressor.
Heating Confirmation
- After a few minutes of operation,the unit will begin heating. Again,
discharge air temperature should be 8° - 10° cooler than the air entering the unit when heating.
Initial Heating
- Check the water temperature and note the time. A heat pumps warms slower but
more economically than other heaters. The rate of heating depends on 3 factors:
How many pounds of water to be heated (10,000 gallons = 83,300 pounds of water).
How many degrees the water needs to be heated. It takes 1 BTU to heat 1 pound of water 1°.
How many BTUs the water loses. The warmer the air, the less time it takes to heat the water.
NOTE: Use a pool blanket to reduce BTU loss. Also turn off all fountains, sprays
and other water features.
Initial heating time (operating 24 hours per day) may vary from 2 days to 1 week. After initial
heating, operating time is reduced to match heat loss.
