How long has the unit been operating? During ini-
tial pool heating in cold weather, it may require a
week to elevate the water temperature to a com-
fortable level. Normally, it takes about 4 days.
How many hours per day is the unit operating?
Remember that the heat pump pool heater only
operates while the pool pump is running.
Set the
time clock to permit 24 hour per day operation. After
the desired temperature is reached, return the unit to
normal operation of 8–10 hours per day.
•
Is airflow through the unit being obstructed?
Restrictions such as shrubbery, tall grass, dirty
coils, or any other obstruction to airflow will reduce
performance.
•
Is the pool blanket/cover being used?
Unblanketed pools can lose up to 10 degrees per
night compared to 4 degrees or fewer when a
blanket is used. Without a blanket, the total heat
gained during the day can be lost overnight.
•
Are rapid heat losses occurring in some other way,
such as high wind, spillage, rainfall, flow through
solar panels at night, or a high water table?
B. UNIT IS NOT RUNNING
•
Is the temperature display ON? If not, the circuit
breaker may be shut OFF or tripped. Reset the
breaker by switching it OFF, and then back ON.
Verify that the breaker is set and operating
properly before calling for service.
•
Is the thermostat setting and the Pool/Spa setting
correct? Verify that the temperature has been
properly set on the thermostat, and that it is
high-
er
than the current water temperature.
•
Have you waited approximately 5 minutes for the
time delay? After the unit has been running and
then shut OFF for any reason, there is a delay
before operation can begin again.
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 unit capaci-
ty 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 gen-
erally warmer.
•
Is the
Heat Light
ON? If not, then the thermostat
setting is not higher than the temperature of the
water. Raise the thermostat setting.
C. CONDENSATION SEEMS EXCESSIVE
Heat pump pool heaters can produce a large amount
of condensation (water) during operation. If you sus-
pect that the unit is leaking:
a.
Use a pool chemistry test kit to confirm there is no
chlorine in the condensation.
Or,
b.
Shut the unit OFF and leave the filter pump run-
ning to see if the water stops dripping. If the water
stops dripping, the unit is
not
leaking.
Service Call Verification
NOTE:
The Raypak Service number is
800-260-2758.
For units in Canada, call
800-268-6966
.
Before you make a service call,
first
determine if the
problem is:
•
Warranty Service
•
Unit operation (power supply, water flow, or time
clock adjustment)
Power Supply
•
Verify that all circuit breakers are reset and work-
ing properly.
•
If the temperature display still does not light, con-
tact the installing dealer, since it may be a power
problem requiring an electrician.
Water Flow
•
Verify that the pool filter is clean to provide good
flow.
•
Verify that valves are properly positioned to allow
adequate water flow through the unit.
NOTE:
The heat pump pool heater will not run when
the
Remote
position is selected on the Pool/Spa
selector switch and there is no remote control sys-
tem attached.
NOTE:
The
MANUFACTURER IS NOT RESPON-
SIBLE
for these adjustments.
