❖ Be sure to inspect the outside of the heat pump and remove
anything obstructing air entering or leaving the heat pump.
❖ What is the air temperature? Your heat pump may be in a
defrost mode. A Blue Defrost light will be on. This
indicates that the air temperature is too cold to support
heating. When the temperature warms up, the heat pump
will begin to heat your pool or spa. The Defrost light will
go off.
Heat Pump Not Running
❖ Is the Amber Power light on? If not, check and reset the
circuit breaker to the heat pump to insure that it is getting
power.
❖ Is the Green Flow light on? If not, is the pump supplying
water to the heat pump on? This pump must be running in
order for the heat pump to come on. If pump is on, check
that all valves are in their proper operating positions. Also
check the pool water filter, is it time to clean?
❖ Please note and remember that the heater will not re-start
for 5 minutes after it has been stopped for any reason.
❖ Your heat pump may be equipped with a Low Ref
(refrigerant) light, if on, call Aqua Cal for service at 1-800-
786-7751. Your heat pump may be equipped with a High
Ref (refrigerant) light, if on, see note under “Heat Pump
Going Off and On” below.
❖ If after checking all of the above, the heater still does not
come on, call Aqua Cal for service at 1-800-786-7751.
Water Leaking out of Heat Pump
(Is it a leak or natural condensation from normal
operation? Here’s how to find out).
❖ Shut your heat pump off leaving the water pump running.
In a couple of hours, there should be marked reduction in
the water around the bottom of the heat pump.
❖ If you believe that the heat pump is leaking, you can check
the water draining out the base of the unit for the presence
of the sanitizer that you are using for your pool. Take your
test kit and check a sample of the water for chlorine or
bromine. If the sample tests positive call Aqua Cal for
service at 1-800-786-7751. If the test is negative, the water
is probably condensate, unless you are using an ionizer or
ozone generator to sanitize your pool.
Low Ref Light On or Intermittently On
❖ If your heat pump is equipped with a red Low Ref
(refrigerant) light and it is “on” or intermittently comes on,
call Aqua Cal for service at 1-800-786-7751.
Heat Pump Going Off and On at Five Minute Cycles
❖ If equipped, is the red High Ref (refrigerant) light on or
briefly going on just before the heat pump shuts off? If so,
this is usually indicative of low water flow through the
unit. Check for improperly positioned valves or a dirty
filter. Correct this and the unit should operate. If not, call
Aqua Cal for service at 1-800-786-7751.
❖ Certain types of pool cleaners can also cause the heat
pump to cycle on and off. If you have a suction type of
cleaner plugged into your pool skimmer and it breaks the
surface when going up the walls of the pool, the air it sucks
into the filter line can cause the heat pump to shut off. If it
does, the heater will not restart for five minutes. Low water
levels in the pool or spa can also cause the surface
skimmer to suck in air causing the heat pump to cycle. Be
sure to maintain proper water levels.
