- Head Loss – 30 GPM = 1.5 PSI, 70 GPM = 8.2 PSI
PLEASE NOTE –
If minimum flow rates are not met, heat pump performance is reduced and
performance will suffer. Internal safety devices may deactivate the heat pump
with the following errors:
l Operate water filtration devices per manufacturer’s specifications. Dirty
filters can cause a reduction of water flow to the heat pump. An increase of
7-10 psi (48 to 69 kPa) higher than the clean filter pressure typically
reduces flow rates. This requires the filter to be cleaned or back-washed.
l Keep baskets free of debris. A large quantity of debris in the pump and
skimmer baskets can reduce water flow.
l Check for improper valve settings. A partially closed valve after the
filter, or a full-open bypass around the heat pump, will cause insufficient
water flow through the heat pump.
l The maximum static pressure (or operating pressure) is 50 psi (345 kPa).
These specifications relate to the heat pump only.
l Code-specified whole system turnover rates must be satisfied.

water through loose plumbing connections may result in damage to circulation
pump, pool and spa structures, and other equipment.
Light Freeze Conditions
A light freeze is when the ambient air temperature falls below 32 degrees
Fahrenheit (0° C) for less than 8 hours. Typically during light freeze
conditions circulating (or moving) water will not freeze. Temporarily activate
the filter pump for continuous operation during light freeze conditions.
Hard Freeze Conditions
A hard freeze is when the ambient air temperature falls below 32 degrees
Fahrenheit (0° C) for more than 8 hours. In areas where this condition is
prevalent and sustained, the heat pump MUST be winterized for hard freeze
conditions. Follow the correct procedure depending on the type of heat
exchanger found in the heat pump.

1. Disconnect the plumbing to the heat pump at connection unions (removal is
counterclockwise).
2. Allow water to drain completely from the heat pump. Expect to see a lot of
water drain out at first, and then a small amount to continue to drain out
over a long period.
3. After heat pump has fully drained, partially reconnect plumbing connection
unions. 4. Winterizing is complete. 5. When ready to use the heat pump again,
hand-tighten connection unions. Reconnect electrical
power, and set the operating mode on the heat pump. Activate the filter pump.

NOTICE
Failure to heed the following may result in damage to equipment.
l Service by unauthorized personnel will void the heat pump warranty.
FLOW LED is off
ISSUE Low or no water detected.
RESOLUTION
1. Confirm the filter pump is on. 2. If a multiple-speed filter pump is being
used, run at a higher speed to determine if the error persists. Do
not exceed the maximum flow rate for your model. 3. Confirm water is not being
diverted away from the heat pump.
l See “Water Flow Rates” on page 9.
DEFROST LED is on
ISSUE The heat pump has sensed the evaporator coil is icing up.
RESOLUTION
PASSIVE DEFROST
When ice starts to form on the coil, the compressor will stop operating while
the fan continues to operate.
l When the coil’s temperature rises above 38° F, the compressor is restarted
and heating resumes. l If the coil’s temperature remains below 38° F, the
compressor will remain off.

FAULT LED is rapidly blinking (Control panel unresponsive) ISSUE The heat pump
firmware needs to be reloaded on the control board. RESOLUTION
1. If the heat pump is connected to a PoolSync® WI-FI controller and is
connected to the internet, the heat pump will automatically perform a firmware
recovery.
2. If no PoolSync® WI-FI controller is connected, the heat pump will require
service from a qualified technician.
FAULT LED is blinking 1 time ISSUE The refrigerant system’s high-pressure or
low-pressure switch is showing as open. RESOLUTION Determine if an
insufficient amount of water is being supplied to the equipment.
1. Confirm the filter pump is on. 2. If a multiple-speed filter pump is being
used, run filter pump at a higher speed. Do not exceed maximum flow
rate for the model. 3. Confirm water is not being diverted away from the heat
pump.
l See “Water Flow Rates” on page 9. 4. The water pressure switch may be
incorrectly calibrated. See “Adjusting Water Pressure Switch” for more
information.
FAULT LED is blinking 2 times ISSUE The heat pump has locked due to five high-
pressure or five low-pressure faults during one call for heating. RESOLUTION
1. Deactivate power to heat pump, wait five seconds, then reactivate power to
the heat pump to clear error. 2. Troubleshoot the high-pressure issue causing
the error. See “FAULT LED is blinking 1 time” above.
FAULT LED is blinking 3 times ISSUE Incoming water temperature exceeded 110° F
and the unit is locked with a high temperature fault. The heat pump will not
operate until incoming water temperature drops to 100° F or lower. RESOLUTION
1. Determine if another heat source (gas heater, solar heater, etc.) is
heating water being sent directly to the heat pump. This situation will need
to be corrected before continuing.
2. Rule out an incorrect reading from the water temperature sensor. Verify
existing water temperature with an accurate thermometer. If heat pump’s sensor
is inaccurate, the water temperature sensor may require replacement.

heat pump contains refrigerant under pressure. Repairs to the refrigerant
circuit must not be attempted by
untrained or unqualified individuals. Service must be performed only by
qualified HVAC technicians. Recover refrigerant before opening the system.
(missing or bad snippet)
l Service by unauthorized personnel will void the factory warranty.
Please perform the following troubleshooting. For further assistance, please
contact AquaCal. See “Contacting AquaCal AutoPilot, Inc.” on page 1.
Display Panel Not Responding
1. If the heat pump is controlled be an external controller, confirm the
external controller settings. See “Operating Heat Pump (With an External
Controller)”.
2. If the issue is still occurring, disconnect external controller from the
heat pump. Then check operation at heat pump.
l If display panel responds, the problem lies with the external controller or
its installation. Contact the manufacturer of the external control device.
Page – 26
3 – Troubleshooting
Heat Pump Not Running
1. Confirm equipment is receiving power. Is the heat pump display
illuminated?
l If not, confirm the main breaker (located at the power supply panel) and the
disconnect switch (located near the heat pump) are both turned on.
l Confirm the power switch on the heat pump’s display is set to on. l If the
display still does not illuminate, it is recommended that the heat pump
installer or electrician confirms heat
pump is receiving power.
2. Confirm thermostat is set correctly. See “Dial Control Panel”.
l When heating the water is desired, the thermostat should be set above the
current water temperature.
3. If an error code is displayed, diagnose and correct the cause of the code.
See “Fault Codes” on page 24. 4. If the heat pump is using an external
controller, the heat pump may not be set correctly at the external
controller.
l See “Operating Heat Pump (With an External Controller)”.
Heat Pump’s Tripping Breaker
1. Have an electrician confirm breakers are in good condition and properly
sized for the heat pump. 2. If a fault occurs immediately when the compressor
starts, a qualified technician should evaluate the system.
Heat Pump Won’t Shut Off
1. Confirm the heat pump has reached the desired temperature set on the
thermostat. The heat pump will continue to run until the set temperature is
reached.
2. If the heat pump is using an external controller, it may not be set
correctly.
l See “Operating Heat Pump (With an External Controller)”.
Heat Pump Is Running, Not Heating
1. If the heat pump is using an external controller, confirm it is set
correctly.
l See “Operating Heat Pump (With an External Controller)”. l If the heat pump
is still not running correctly with this device, contact the installer of the
external controller device
or the device’s manufacturer for further assistance.
3. Confirm thermostat is set to the desired water temperature. 4. Confirm
valves are correctly positioned to heat the correct body of water (either the
pool or the spa). If heating
a spa that overflows into a pool, confirm the spa is isolated when being
heated (not flowing into the pool). 5. Confirm heat pump is transferring heat
into the water.
l Measure the temperature of air discharge coming out of the heat pump fan. If
discharge air is between 8° to 10° colder than the outside ambient air, the
heat pump is moving heat into the water.
6. If an error code is displayed, diagnose and correct cause of code. See
“Fault Codes” on page 24. 7. Confirm that filter pump has a sufficient run-
time. The heat pump will not run (or heat the water) without water
flow. Heat Pump equipment will generally be set to run 24 hours a day in
commercial applications.See “Initial Heating Recommendations” on page 21. 8.
If heating a spa, deactivate air blower or venturi (if equipped) to allow for
quicker heating times. For pools, deactivate water features, such as slides,
waterfalls, or fountains to allow water to retain heat. Use of a liquid pool
blanket product can also compensate for excessive heat loss.
l See Available Accessories on page 22.for more information on liquid
blankets.
Ice forming on the heat pump When conditions are too cold for proper
operation, the heat pump will enter a defrost mode. This prevents ice from
building up on the evaporator coil.
Page – 27
3 – Troubleshooting
l The heat pump may develop a fine layer of white frost on the outside coil
before entering the defrost mode. This is normal.
l If heavy ice (not frost) starts to build up, shut off the heat pump. Contact
the installer or manufacturer. l If the ambient air temperature will be
falling below 32° F for more than 8 hours, winterize equipment.
Water Coming From Heat Pump The water may be normal condensation produced as a
by-product of the heat pump’s refrigeration process. The heat pump can produce
8 to 10 gallons of condensation per day depending on the humidity of the
ambient air. Determine if the water is condensation or a possible leak.
1. Deactivate heat pump, leaving the filter pump on. After several hours,
determine if water is still coming from the heat pump.
2. If using chlorine or bromine as a pool / spa sanitizer, test the water
around the heat pump using a test strip. If the test strip indicates that
chlorine or bromine is present, a leak may exist.
PLEASE NOTE If desired, a kit is available to re-direct condensation water
away from the heat pump. See “Condensation Drain Kit (# STK0202)” on page 22.
