When the unit has been operating in the heating mode for
a few minutes, the discharge air temperature should be
8°–10°F (4.4°–5.6°C) cooler than the air entering the unit.
When the unit has been operating in the cooling mode for
a few minutes, the discharge air temperature should be
8°–10°F (4.4°–5.6°C) warmer than the air entering the unit.
NOTE:
Heating is more efficient during warmer daylight
hours and cooling is more efficient during cooler night
time hours.
13. SYSTEM START-UP
1. Verify that the Digital Board is displaying a temperature
and the pool pump is running and water is circulating
properly.
2. Verify that the Board is programmed so that the
desired temperature of the Pool and Spa is higher
than the displayed current water temperature.
3. Allow the heater to operate for a few minutes to
stabilize operating pressures and to allow various
component temperatures to normalize.
4. Verify that the discharge air temperature is
approximately 8°–10°F (4.4°–5.6°C) cooler than the
air entering the unit. If not, see"Troubleshooting" on
page

14. SEASONAL START-UP OR
ANNUAL CHECK
NOTE:
At the beginning of the heating season, or
whenever the pool water temperature is to be raised
several degrees, the pool pump and heater 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.
NOTE:
If the pool pump and heater 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 heater 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.
4. Set the valves to ensure proper water flow through
the unit.
15. SUMMER SHUTDOWN
If you do not plan to use the heater during the summer
months, secure and protect it as follows:
1. Turn the unit circuit breaker or disconnect switch to
OFF.
2. Leave the valves set the way they are unless
additional circulation is required. DO NOT stop all
flow through the heater.
3. IMPORTANT: Remember to reset the valves before
the next heating season, or the unit will not operate
properly.
16. FREEZE PROTECTION
If the unit is installed in a location subject to freezing
conditions, it is important to protect the water circuit from
freezing, just as should be done for the pump and filter.
System Drain-Down
1. Turn the unit circuit breaker or disconnect switch to
OFF.
2. With the pool pump OFF, close the external shutoff
valves and loosen the inlet and outlet water unions
to allow water to drain. Use a Wet/Dry Vac or air
pressure to remove excess water.
3. Loosely re-attach the unions.
4. Cover the unit with a waterproof cover.
Continuous Pump Operation
It is also possible in some areas to prevent unit freeze
damage by operating the pump continuously during
freezing weather. However, this results in significantly
higher pump operating costs. Further, if a sustained power
failure occurs, the unit MUST be drained anyway, or freeze
damage could result.
17. MAINTENANCE
NOTE:
The heater MANUFACTURER IS NOT
RESPONSIBLE for maintenance adjustments.
The following maintenance procedures are designed
to keep your unit operating at a high level of reliability.
Maintenance must be performed on a periodic basis
to maintain warranty coverage and prevent system
failures and performance degradation.
Air Coil Cleaning
Efficient operation depends on free circulation of air
through the thin and tightly-spaced fins of the evaporator
coil(s). The evaporator must be cleaned whenever it has a
buildup of dirt or debris.
