oils, or any other obstruction to airflow will reduce
performance.
• Is the pool blanket/cover being used?
U
nblanketed 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 or control panel Power
lamp 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. On analog
units, all 3 lamps should be illuminated and the fan
should begin to run.
• 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.
• Is the Heat Light or Heat Demand lamp 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.
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.
Service Call Verification
NOTE: The Raypak Service number is 800-260-2758.
Before you make a service call, first determine if the
p
roblem 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 or the Power lamp on
the control panel still does not light, contact 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.
• If the Water Flow lamp (analog models) on the
control panel still does not light, and water is circu-
lating in the pool, verify that all valves are
positioned correctly.
Time Clock Adjustment
Verify that the time clock is set to permit the unit to run
long enough to heat properly.
NOTE: The MANUFACTURER IS NOT RESPON-
SIBLE for these adjustments.
