NOTE: The heat pump will be OFF when the Remote
position is selected on the Pool/Spa 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. If not, see Section IX, Troubleshooting.
Seasonal Start-Up or Annual Check
NOTE: At the beginning of the heating season, or whenever the pool water temper-
ature is to be raised several degrees, the pool pump and heat pump may need to
operate continuously for several days. During summer months, only a few hours
per day may be necessary, or none at all.
1. Remove leaves, pine needles, etc. from the evaporator coil. Clean the coil by gently applying
a mild solution of household liquid soap and water.
2. Gently rinse the coil with water; do NOT use high pressure.
3. Backwash or otherwise clean the pool filter. If necessary, clean the skimmer basket and pump
strainer.
4. Set the valves to assure proper water flow through the unit.
NOTE: If the pool pump and heat pump shut OFF before the water temperature is
raised to the desired level, you must lengthen the running time of both. To do this,
reset the time clock dial for the longer running time, or manually operate the pump
with the timer override switch. Since the heat pump capacity and efficiency are both
greater at higher ambient air temperatures, run time should be set to take
advantage of all daylight hours, when the air is generally warmer.
VI. Summer Shutdown
If you do not plan to use the heat pump during the summer months, secure and protect it
as follows:
1. From the control panel, turn the control switch to
Remote (OFF).
2. Turn the heat pump circuit breaker or disconnect switch to OFF.
3. Leave the valves set the way they are unless additional circulation is required. DO NOT stop
all flow through the heat pump.
4.
IMPORTANT: Remember to reset the valves before the next heating season, or the heat pump
will not operate properly.
