Throughout this document, safety signals have been placed where particular attention is
required.
ta`z WARNING - signals relate to personal safety.
CAUTION - signals promote avoiding damage to the equipment.
When installing and using your heat pump basic safety precautions must always be followed, including the
following:
AA WARNING - Failure to heed the following may result in injury or death.
o Installation and repairs must be performed by a qualified technician.
The heat pump contains refrigerant under pressure. Repairs to the refrigerant circuit must not be attempted by
untrained and / or unqualified individuals. Service must be performed only by qualified HVAC technicians.
Recover refrigerant before opening the system.
The heat pump utilizes high voltage and rotating equipment. Use caution when servicing.
o Electrical installation and service should be performed by a Licensed Electrician only.
Improper water chemistry can present a serious health hazard. To avoid possible hazards, maintain pool / spa

If water flow through the heat pump is reduced, performance will suffer and internal safety devices may
deactivate the heat pump with error codes HP and HP5, or (if equipped) an LP and LPS.
o Operate water filtration devices per manufacturer's specifications. Dirty filters can cause reduced water flow to the
heat pump. An increase of 7-10 psi higher than the clean filter pressure typically reduces flow rates. This requires
the filter to be cleaned or back -washed
° Keep baskets free of debris. Similar to a dirty filter, large volumes of debris in the pump and skimmer baskets can
reduce water flow.
o 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.
o The maximum static (or operating pressure) is 50 pounds -per -square -inch (PSI). These specifications relate to the
heat pump only. Code -specified whole system turnover rates must be satisfied.
4.1.c Adjusting Water (Flow Using AT (Delta.-T)
The Delta-T is the temperature difference between the water temperatures entering and leaving the heat
pump. The equipment can be fine-tuned for maximum performance by balancing water flow rates to
maintain an ideal AT.
o Installed Temperature / Pressure probes and ports are required to perform the following procedures.
• This adjustmcut procedure is to be completed with the unit in HER anode only; REH and CD® discharge
temperatures are not shown.
PLEASE NOTE -
Temperature /Pressure ports are required for all commercial applications.
They are strongly recommended (but not required) for residential installations.
1. Adjust heat pump thermostat to its lowest setting while in
HER mode.
2. Deactivate the water filtration pump.
3. Adjust valves to a halfway open position leading to the
heat pump.
4. Adjust valves to a fully open position leading away from
the beat pump.
5. Activate the pool water filtration pump.
6. Slowly turn the thermostat up until the heat pump
activates.
o After a four -minute delay, the heat pump
compressor will start.
7. With the heat pump running, confirm water filtration
pump is operating properly with adequate flow and no
short cycling. If needed, clean filters leading to the heat
Temperature / Pressure Port
(Shown with Probe)
pump.
8. Wait for water and refrigerant pressure to stabilize (approximately 5 minutes).
9. Adjust valves in the following order:
A. Adjust valve leading away from the beat pump to correct temperatures measured with a temperature
pressure probe.
B. Allow pressure to stabilize. Then check temperature again. Re -adjust valve leading away from the
heat pump as needed.
10. Mark valves at these positions for future reference.
Temperature differences are based on pool temperatures of 72° (+ or — 3° F). For water
temperatures outside this range, contact AquaCar Technical Support.

,_ 2 Cleaning Equipment
Cleaning and polishing your heat pump regularly can protect its appearance and longevity. More frequent
servicing may be required for heat pumps located in sandy or coastal areas where sand and salt spray can
become detrimental factors to equipment.
A WARNING - Failure to heed the following may result in injury or death.
Possible electric shock hazard - Deactivate power to all electrical devices on the pad when washing heat pump.
Do not restore electrical power until equipment is completely dry.
?! CAUTION - Failure to heed the following may result in equipment damage.
•Do not use a pressure cleaner to wash heat pump. Damage to heat pump components may result. If using a hose
end spray nozzle adjust spray pattern to low strength only.
o Do not spray water directly into the interior of the heat pump; damage to components may result.
• Do not use chemicals on the display panel.
Page -12
Cleaning
1. Wash outside cabinet using a low-pressure water hose. A high-pressure water stream will cause iamage to the
aluminum fins of the heat pump. This damage is not covered under product warranty.
2. While the heat pump is still wet, use an approved cleaning agent to clean the exterior of the heat pimp. Do not
use chemicals on the display panel.
3. Use a detergent -dampened cloth to wipe the heat pump's exterior cabinet.
4. Flush all exterior with fresh water using -a low-pressure water hose.

4.4 Winterfizing _ J
A WARNING - Failure to heed the following may result in injury or death.
o Deactivate all electrical power to heat pump before performing hard freeze procedures.
?`. CAUTION - Failure to heed the following may result in equipment damage.
o Failure to winterize heat pump may result in serious equipment damage. Freeze damage is not covered under the
heat pump warranty.
• While the plumbing connections are in the winterized condition (not fully tightened), it is imperative the pool
and spa water not be circulated through the heat pump. Loss of water through loose plumbing connections may
result in damage to circulation pump, pool and spa structures, and other equipment.
Light Freeze Conditions
There are two freeze conditions requiring heat pump attention. A light freeze is when the ambient air
temperature falls below 32 degrees Fahrenheit for less than 8 hours. Typically during light freeze conditions
circulating (moving) water will not freeze. Override time clocks and allow filtration system to run
continuously during light freeze conditions.
Surd Freeze Conditions
A hard freeze is when the ambient air temperature falls below 32 degrees Fahrenheit 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.
Rdentify Exchanger:
I. Deactivate all electrical power to heat pump.
2. Deactivate filter pump.
3. Remove front access panel.
4. Identify heat pump exchanger from illustrations in this section. Then follow procedure for that heat pump's
exchanger.

pool).
S. If an error code is displayed, determine and correct the condition causing the code. See "Fault Codes" on page
16.
6. Confirm heat pump is transferring heat out of the water.
Measure the temperature of air discharge coming out of Treat pump fan. If discharge air is Atween 80 to
10* warmer than outside ambient air (not coming out of heat pump), then the heat pump is moving heat
out of the water.
Confirm that filter pump has a sufficient run-time. The heat pump will not run (or cool the water) without
water flow. Heat Pump equipment will generally be set to run 24 hours a day in commercial appliations.See
"Initial Cooling Recommendations" on page 22.

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. If using chlorine or bromine as a pool / spa sanitizer, use a test strip in the water at heat pump to determine if
sanitizer is present. If sanitizer is present, a leak may exist.
2. Deactivate heat pump, leaving the filter pump on. After several hours, determine if water is still coming from
the heat pump.
