check unit data plate to make sure you have the proper model, before installing
GENERAL INFORMATION
The information in this manual was prepared to assist in the proper installation, operation,
maintenance and service of your new heat pump pool heater Please read the entire manual
and follow all instructions Improper installation and use can result in damage to the heater,
unsatisfactory operation, and may void the warranty Retain this manual for quick reference
INSTALLATION
When selecting a location consider the following:
• Heater must be located outdoors
• Minimum of 24” of clearance on access / service side of heater
• Minimum of 18” of clearance on all three air intake sides of heater
• Minimum of 48” of clearance for air discharge (top of unit)
• The heater should sit on a solid level surface sufficient above grade to prevent water from
entering it, and allowing condensate to drain from base
• The length of water piping and electric should be kept to a minimum to avoid capacity loss
and decreased efficiency
WATER FLOW & CONNECTIONS
Water connections are made at the rear of the heater Both water in and out are labeled at the
water connections LEFT REAR = WATER IN and RIGHT REAR = WATER OUT
2” unions are supplied and are made to accept 2” rigid PVC pipe NOTE: unions can be used
for quick drainage of your heater and winterizing
• Heater must be piped downstream from filter in the pool return line
• Inline chlorinators must be piped downstream from heater A check valve should be
installed between the heater and chlorinator to prevent drain back of the chlorine when
the pump is off A chemical trap may also be piped at least six (6) inches above the
height of the chlorinator

seconds of inactivity and the new set point will be stored
• When the spa water temperature falls 1º F below the set point, the control will energize spa
heating mode (compressor) after the time delay has expired
• During heating once the water temperature reaches the set point, the compressor turns off
CHEMICAL USE
Water quality must be checked regularly and maintained within recommended limits at all times
Failure to maintain the proper water quality will greatly reduce the life of your heater
• Never add chemicals directly into skimmer
• Automatic chlorinators must be piped downstream from the heater A check valve must be installed
between the chlorinator and heater to prevent raw chlorine from draining back into the heater A chemical
trap may be piped at least six (6) inches above the chlorinator See piping diagram B
Always maintain the followin water quality requirements:
PH LEVEL 7.4 to 7.8
CHLORINE CONCENTRATION 1 to 5 PPM
TOTAL AL YALINITY 100 to 200 PPM
CALCIUM HARDNESS 100 to 300 PPM

10
START-UP
Before proceeding with this section make certain all plumbing connections are airtight and leak free
Flow rates should not exceed 70 GPM maximum Use of an external bypass is necessary at 70 GPM
and above Minimum flow rate is 20 GPM
• Turn filter pump time clock to the ON position and set filter pump hours For initial heating, the pool
heater and filter pump may need to run continuously until your desired temperature is reached After
initial heating is achieved, the heater will run only to maintain your desired temperature
• Turn power supply to heater ON
• The control panel will light up and display either POOL – HEAT OFF or the actual pool water
temperature
• Select POOL TEPERATURE SETPOINT or SPA TEMPERATURE SETPOINT and set your desired
water temperature by scrolling either up or down
• If your programmed water temperature is above the actual water temperature and the 5 minute time delay
is satisfied the compressor will start
NOTE: Each time the compressor turns off; it is protected by a 5 minute anti-cyclin delay.
INITIAL HEATING
Initial heating may require you to run your heater and filter pump continuously for at least 24 hours, or
more, depending on the following factors:
• Temperature difference between actual water temperature and desired water temperature
• Size of pool
• Ambient air temperature, the cooler the air temperature the longer the heating time
• Heat loss (evaporative, convective, radiative and conductive)
• A pool cover / solar blanket may reduce initial heating time by up to 50 percent
Reducin Heat Loss - Pool Cover / Solar Blanket
We highly recommend the use of a pool cover / solar blanket Covering your pool is the single most cost
effective means of reducing heat costs from 50 to 70 percent Heating a pool without a cover is like heating
a house without a roof They also reduce the amount of maintenance costs By reducing evaporation,
covers reduce the quantity of chemicals needed

11
Because evaporation accounts for about 70 percent of pool heat loss, the beneficial effect of using a pool
cover /solar blanket can be dramatic
Wind Speed Reduction
Reducing wind velocity at the water surface reduces convective and evaporative losses Fences, trees, hills,
or tall hedges close to the pool perimeter are effective windbreaks Locate these obstructions to take
maximum advantage of their effectiveness as windbreaks, without shading the pool surface from the sun
Defrost Cycle
The heat pump pool heater has automatic defrost When the outdoor temperature drops below 40 °F, frost
may start to form on the evaporator coil Frost buildup will be heaviest on humid days when the
temperature is between 35-40° During the defrost cycle, the display will show “DEFROSTING” to
indicate that the unit is defrosting During this time the fan is running and the compressor is inactive
Internal Protection Analyzers
The heater is equipped with internal devices to monitor and protect the integrity of the unit Should an
abnormal condition occur, these devices will interrupt the operation of the unit and may display the
appropriate code on the control panel
• LOW WATER FLOW: Indicated by “FLO”, “HIGH REFRIGERANT PRESSURE”, or “3 HPS
STRIKES LOCKOUT” on the control panel The heater is designed to run efficiently above twenty
(20) GPM If there is insufficient water flow, the unit will shut down, protecting the compressor
The usual causes for these conditions are a dirty pool water filter, a restriction in the return line
(i e skimmer), or improper valve positioning
• NO WATER FLOW: Indicated by “LOW FLOW” on the control panel When the filter pump is off,
or if the water flow to the heater is interrupted during the heating mode, the internal water pressure switch
will shut down the unit When normal water flow resumes, the heater will automatically restart itself
• Other analyzer codes include: “FL3”, “LP3”, “LP”, “dPO”, “PO”, “dPC”, “Pc”, “PLE”, “CSE” and
“SPi”
The TROUBLESHOOTING CHECKLIST on page 11 goes into detail on these analyzers codes

MAINTENANCE
WARNING: DISCONNECT ELECTRICAL POWER TO UNIT BEFORE STARTING ANY
MAINTENANCE TO PREVENT SERIOUS INJURY FROM SHOCK.
Protectin your Heater
• Keep your pool filter system clean and free of restrictions to ensure proper water flow
• Check water chemistry regularly Misuse of chemicals will cause permanent damage to
your heater and other pool equipment Manufacturers can void warranties for damage as a
result of poor water quality
• Free airflow is essential Keep the evaporator coil clean and free of weeds, leaves, glass
clippings, dirt and other debris that will decrease the airflow Keep fences and shrubs away
from air inlets (sides and back of heater)
• Frequent rinsing of the evaporator with fresh water will remove build up from its surface
Always spray the coil gently with a regular garden hose being careful not to bend aluminum
fins
• Regular cleaning of the cabinet will improve its appearance and extend the life of the
finish
Winterizin
When the heater is exposed to freezing temperatures, it is essential that all water within the
unit be properly drained When water freezes, it expands, damaging piping
• Turn thermostat settings to OFF Turn filter pump to OFF
• Turn power to unit OFF (i e pull disconnect or turn circuit breaker OFF)
• Disconnect water inlet and outlet unions at the back of the unit Be careful not to lose
rubber o-rings
• Flush the heater piping out with fresh water to remove any residual chemicals
• Use low-pressure air or vacuum to remove water that has accumulated inside the piping of
the heater
TROUBLESHOOTING CHEC LIST
• Check to see that the electrical power is on Reset breakers, or replace fuses if necessary
• Check to be sure the electric control panel is set properly The desired temperature must be
set above
the actual pool or spa temperature for the heater to run
• Check to make sure the evaporator coil has enough clearance and that there are no
restrictions to its airflow
• Certain ambient air conditions may cause the heater to go into defrost mode, displayed on
the control panel as “AIR DEFROSTING” or “REVERSE CYCLE.”
