System Start-Up
1. Verify that the Digital Board is displaying a temper-
ature 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 heat pump pool heater to operate for a
few minutes to stabilize operating pressures and to
allow various component temperatures to normal-
ize.
4. Verify that the discharge air temperature is approx-
imately 8°–10°F (4.5°–5.6°C) cooler than the air
entering the unit. If not, see the Troubleshooting
Section.
Heat/Cool Operation
The Raypak Professional models come standard with
heat/cool operation. The heat/cool model is designed
to both heat and cool the pool. To select heat or cool
mode, push the
SET
key until
H/C
is displayed. Press
the
DOWN
arrow key to select heating (
hea
), or the
UP
arrow key to select cooling (
col
). Set the desired
setpoint temperature as described earlier in this man-
ual.
When the unit has been operating in the heating mode
for a few minutes, the discharge air temperature
should be 8°–10°F (4.5°–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 (4.5°–5.6°C) warmer than the air
entering the unit.
NOTE:
Once the control has been programmed to
the desired pool water temperature, the pro-
grammed temperature will be displayed for
approximately 5 seconds. The digital display will
then show the actual pool water temperature.
NOTE:
Remove the pool/spa blanket and turn on
any fountains, sprays or other water features to
speed cooling.
NOTE:
Heating is more efficient during warmer day-
light hours and cooling is more efficient during cooler
night time hours.
Seasonal Start-Up or Annual
Check
1. Remove leaves, pine needles, etc., from the evap-
orator 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 nec-
essary, clean the skimmer basket and pump
strainer.
4. Set the valves to ensure proper water flow through
the unit.
Summer Shutdown
If you do not plan to use the heat pump pool 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 addi-
tional circulation is required.
DO NOT
stop all flow
through the heat pump pool heater.
3.
IMPORTANT:
Remember to reset the valves
before the next heating season, or the unit will not
operate properly.
NOTE:
At the beginning of the heating season, or
whenever the pool water temperature is to be raised
several degrees, the pool pump and heat pump pool
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.
NOTE:
If the pool pump and heat pump pool 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 heat pump
pool 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.
