Introduction
Installation Considerations
WARNING: This pool/spa heat pump pool heater is
an electromechanical machine that incorporates a
ressurized refrigerant gas in a sealed system.
p
ONLY trained and qualified service personnel are
uthorized to install or service this equipment.
a
Without proper training and knowledge of such
equipment, any attempt to install or service the unit
could result in serious injury or even death.
This manual contains important information on the
use, maintenance and troubleshooting of your new
heat pump pool heater. This unit must be properly
installed, maintained and operated for optimal performance.
This heat pump pool heater is an extremely efficient,
economical machine designed specifically for swimming pool heating. It is similar in design and operation
to a typical residential air conditioning system. The unit
employs a hermetic motor/compressor operating in a
refrigeration cycle to extract heat from ambient air and
deliver it to the circulating pool water.
As with all heat pump pool heaters, compared to other
types of heaters such as gas or oil-fired, this heat
pump pool heater has lower heating capacity on a
BTUH/hr basis. As a result, it will be required to operate longer to accomplish the desired results. It may, at
certain times, operate as much as 24 hours per day.
However, this should not be of concern to the owner,
because the unit is designed to operate continuously.
Even though it may operate continuously for many
hours, it will still heat the pool with greater economy
than other types of fossil fuel heaters.
Place a cover or blanket over the pool at night and
other non-use periods. This will keep evaporation, the
cause of main heat loss, to a minimum, and will greatly reduce pool heating costs. During warmer weather,
the cover may be required only at night.
WARNING: Do not install the unit within 3 ft of
ossil fuel burning heaters. Air intake along the
f
sides of this heat pump pool heater could disturb
the combustion process of the unit, and could
cause damage or personal injury.
• Mount the unit on a level, sturdy base, preferably a
concrete slab or blocks. The size of the base should
be at least 3 ft by 3 ft.
• You must install the 4 black rubber sound isolation pads (each 2 inches square) that ship with
the unit. The pads are shipped in a bag with the
unions, gaskets and the I&O manual. Install pads
under the 4 corners of the unit to reduce vibration and sound transmission to the base.
CAUTION: The unit’s supporting base must be high
enough to keep it completely free of standing water
at all times.
Situate the heat pump pool heater carefully to minimize installation costs while providing maximum
efficiency of operation, and to allow adequate service
access, as follows:
• For unrestricted air intake and service access,
position each side of the unit at least 1 ft (30 cm)
from walls, pipes and other obstructions.
WARNING: This unit is designed for outdoor installation; DO NOT install it in an enclosed area such as
a shed or garage.
• Recirculation of cold discharge air back into the
evaporator coil will greatly reduce the unit’s heating capacity and efficiency.
• This unit features an ‘up-flow’ discharge for quiet
operation. Air is pulled up through the evaporator
coil and discharged through the top grill. Allow at
least 5 ft (1.5 m) clearance above the unit for unrestricted air discharge. DO NOT install the unit
under a porch or deck. Refer to Fig. 1.
• To minimize water piping, locate the unit as close
as possible to the existing pool pump and filter.
• If the location of the heat pump pool heater is
below the water line of the pool, the water pressure switch might need to be adjusted or an
external water flow switch might be needed.

Fig. 1: Installation Clearances
• Irrigation water should be directed away from the
heat pump pool heater-water spray can damage
the heat pump pool heater.
• Rain water run offs- the heat pump pool heater
can withstand normal rain. Install rain gutters to
prevent direct steams of rain water to the heat
pump pool heater.
• It is important to keep the area next to the heat
pump pool heater clear of shrubs, bushes and
chemicals containers. They could prevent air from
circulating fully through the heat pump pool heater,
and will affect the operation of the heat pump pool
heater or damage the heat pump pool heater.
• When installed in areas where freezing temperatures can be encountered, drain the water circuit
to prevent possible freeze-up damage. See the
Freeze Protection Section.
• For high wind installation requirements, refer to
the diagram on page 8.

applicable state and local codes. Wiring diagrams are
located on pages 21 through 26.
NOTE: Refer to the National Electrical Code, Article
680, for general requirements for swimming pools
and equipment, and to Article 440 for special considerations necessary for circuits supplying hermetic
refrigeration motor/compressors.
• Locate the equipment disconnect means within 3
feet of the heater’s electrical enclosure, or as
close to the heater as possible. Always satisfy
applicable codes and standards.
• In sizing power wiring, be especially aware of upsizing requirements necessary due to wiring
distances. Always satisfy applicable codes and
standards.
• Electrical installation should be done by a licensed
electrician only.

WARNING: Install a check valve and/or a Hartford
loop AFTER the heat pump pool heater and
BEFORE any chlorinating devices. Install any auto-
atic chemical feeders AFTER the heat pump pool
m
heater. Improper installation of any type of auto-
matic chemical feeders can result in serious
damage to, or premature failure of, the heat
ump pool heater and will void the heat pump
p
pool heater warranty.
Defrost Switch: Prevents heat pump pool heater
operation if ambient air temperature falls below a predetermined safe minimum (approximately 42° F).
Delay Timer: Prevents compressor from short cycling,
which could damage or destroy the hermetic
otor/compressor. Upon water temperature control
m
satisfaction, or other circuit interruptions, this solid
state device will prevent compressor restart for
approximately 5 minutes.
Controls & Indicator Lamps
(Analog Models)
Your analog heat pump pool heater incorporates safety controls and indicators to ensure its safe, reliable
operation (for models with digital controls, see page
11).
Water Pressure Switch: Prevents operation when the
pump is OFF. The unit requires 5 psi minimum pressure.
Water Temperature Control: Pool/spa water temperature is controlled by the heat pump pool heater
thermostat on the unit control panel, which contains a
switch and 2 thermostats, one for setting a heat spa
temperature and the other for a swimming pool temperature. The switch can operate an optional external
control system, or can switch between thermostats for
pool or spa.
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 system attached.
Refrigerant Low Pressure Control: Stops the compressor if refrigerant suction (low side) pressure falls
too low as a result of a malfunction, loss of charge or
extreme cold conditions.
Indicator Lamps: There are 6 indicator lamps located
on the unit control panel (see Fig. 3 below):
• Power (amber lamp): When lit, indicates power is
applied to the unit.
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 system attached.
• Water Flow (green lamp): When lit, indicates normal water flow.
• Heat Demand (green lamp): When lit, indicates
the actual water temperature is below the target
water temperature.
Fig. 3: Indicator Lamps — Analog Models

• Compressor Delay Active (amber lamp): Under
normal operation, when lit, indicates compressor
anti-short cycle timer is active. The fan will run but
the compressor will be OFF for 6 to 8 minutes.
4. Allow the heat pump pool heater to operate for a
few minutes to stabilize operating pressures and to
allow various component temperatures to normalize.
• Defrost Active (red lamp): When lit, indicates unit
s in defrost mode. Defrost mode occurs when ice
i
starts to form on the outside coil. The fan will continue to run but the compressor will stay OFF (not
heating) until weather conditions improve.
• Low Pressure (red lamp): When lit, indicates fail-
ure in the refrigeration circuit. When this lamp is
ON, service is required. Call for service assistance.
System Start-Up
1. Verify that the Power lamp is ON and that the
pool/spa pump is running and circulating properly.
2. Verify that the control panel Spa-Remote-Pool
switch is in the Remote (OFF) position; see Fig. 4
below.
3. Turn the control switch to either Pool or Spa to
turn the system ON and raise the thermostat setting above the current water temperature. At this
time the 2 green lamps should illuminate. The fan
and compressor should start up and run simultaneously.
5. Verify that the discharge air temperature is approxmately 8°–10° cooler than the air entering the unit.
i
If not, see the Troubleshooting Section.
Controls (Digital Models)
Your heat pump pool heater incorporates digital safety
controls and indicators to ensure its safe, reliable
operation (for models with analog controls, see page
10).
Water Pressure Switch: Prevents operation when the
pump is OFF. The unit requires 5 psi minimum pressure.
Digital Water Temperature Control: The pool water
temperature is controlled by the heat pump pool
heater’s digital control system, which gives you the
option of two settings: one for the desired spa temperature and the other for the desired pool temperature.
Additionally, as mentioned earlier, the unit is compatible with most ‘2-wire’ and ‘3-wire’ control/automation
systems.
Fig. 4: Selector Knobs — Analog Models
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 system attached.
Fig. 5: Digital Water Temperature Control
Defrost Sensor: Prevents unit operation if ambient air
temperature falls below a predetermined safe minimum (approximately 42°–48°F, based on humidity).
The compressor will shut OFF but the fan will continue
to run.
Delay Timer: Prevents compressor from short cycling,
which could damage or destroy the hermetic
motor/compressor. Upon water temperature control
satisfaction, or other circuit interruptions, this solid
state device will prevent compressor restart for
approximately 5 minutes.

12
System Start-Up
. Verify that the Digital Board is displaying a temper-
1
ature and the pool pump is running and water is
circulating properly.
Summer Shutdown
f you do not plan to use the heat pump pool heater
I
during the summer months, secure and protect it as
follows:
2. Verify that the Board is programmed so that the
desired temperature of the Pool and Spa is higher
than the displayed current water temperature.
3. Allow the heat pump pool heater to operate for a
few minutes to stabilize operating pressures and to
allow various component temperatures to normalize.
4. Verify that the discharge air temperature is approximately 8°–10°F cooler than the air entering the
unit. If not, see the Troubleshooting Section.
Seasonal Start-Up or Annual
Check
NOTE: At the beginning of the heating season, or
whenever the pool water temperature is to be raised
several degrees, the pool pump and heat pump pool
heater may need to operate continuously for several
days. During summer months, only a few hours per
day may be necessary, or none at all.
1. Remove leaves, pine needles, etc., from the evaporator coil. Clean the coil by gently applying a mild
solution of household liquid soap and water.
2. Gently rinse the coil with water; DO NOT use high
pressure.
1. Turn the unit circuit breaker or disconnect switch to
OFF.
2. Leave the valves set the way they are unless additional circulation is required. DO NOT stop all flow
through the heat pump pool heater.
3. IMPORTANT: Remember to reset the valves
before the next heating season, or the unit will not
operate properly.
Freeze Protection
If the unit is installed in a location subject to freezing
conditions, it is important to protect the water circuit
from freezing, just as should be done for the pump and
filter.
System Drain-Down
1. Turn the unit circuit breaker or disconnect switch
to OFF.
2. With the pool pump OFF, close the external shutoff valves and loosen the inlet and outlet water
unions to allow water to drain. Use a Wet/Dry Vac
or air pressure to remove excess water.
3. Loosely re-attach the unions.
4. Cover the unit with a waterproof cover.
3. Backwash or otherwise clean the pool filter. If necessary, clean the skimmer basket and pump
strainer.
NOTE: If the pool pump and heat pump pool heater
shut OFF before the water temperature is raised to
the desired level, you must lengthen the running time
of both. To do this, reset the time clock dial for the
longer running time, or manually operate the pump
with the timer override switch. Since the heat pump
pool heater capacity and efficiency are both greater
at higher ambient air temperatures, run time should
be set to take advantage of all daylight hours, when
the air is generally warmer.
4. Set the valves to ensure proper water flow through
the unit.
Continuous Pump Operation
It is also possible in some areas to prevent unit freeze
damage by operating the pump continuously during
freezing weather. However, this results in significantly
higher pump operating costs. Further, if a sustained
power failure occurs, the unit MUST be drained anyway, or freeze damage could result.
13
Maintenance
Troubleshooting
NOTE: The heat pump pool heater MANUFACTUR-
R IS NOT RESPONSIBLE for maintenance
E
adjustments.
The following maintenance procedures are designed
to keep your unit operating at a high level of reliability.
Maintenance must be performed on a periodic
basis to maintain warranty coverage and prevent
system failures and performance degradation.
Air Coil Cleaning
Efficient operation depends on free circulation of air
through the thin and tightly-spaced fins of the evaporator coil(s). The evaporator must be cleaned
whenever it has a buildup of dirt or debris.
CAUTION: To clean the fins, spray gently with a
garden hose. DO NOT pressure wash. Doing so
will bend the fins and can void the warranty.
Cabinet Care (optional)
If your unit does not operate, or simply does not heat
our pool water, Fault Codes (digital models), or the
y
indicator lamps (analog models) on the front control
anel, can provide valuable clues as to what is wrong,
p
and may even indicate precisely what the problem is.
Always observe these codes (or lamps) before calling
a service representative. By reporting on the telephone the Fault Codes (or which lamps are ON or
OFF) that are showing, the service rep may be able to
solve the problem without the expense of a service
call.
NOTE: If the compressor fails to start when energized, and there are no faults detected in the wiring,
contact the factory for the appropriate “Hard Start
Kit.”
A. UNIT IS RUNNING, BUT NOT HEATING
• Is water flow through the unit adequate? Check
the unit for obstructions, such as a clogged filter
pump strainer, a dirty filter, or valves not positioned correctly.
The cabinet is designed for outdoor use and requires
little care. However, you can clean it if you wish.
WARNING: Shut OFF electricity to the unit before
cleaning.
Wash the cabinet with soap and water.
Unplug Condensation Drain Holes
The unit extracts humidity from the air as it passes
through the coil, similar to the way a cold drink outside
“sweats” on a hot day. This condensation drains from
the bottom of the unit.
1. Routinely check to be sure the condensation drain
holes in the base of the unit are not plugged with
dirt or debris.
2. If condensation becomes a problem, optional drain
pans are available from your heat pump pool
heater distributor or pool dealer.
• Is the ejected air from the unit 8°–10°F cooler than
incoming air? If so, the unit is extracting heat from
the air and transferring it to the pool.
• Is water condensing on the evaporator and internal copper pipes? This is also evidence of heat
removal from the air. When the air is cool with low
humidity, condensation may not be evident.
• How long has the unit been operating? During initial pool heating in cold weather, it may require a
week to elevate the water temperature to a comfortable level. Normally, it takes about 4 days.
How many hours per day is the unit operating?
Remember that the heat pump pool heater only
operates while the pool pump is running. Set the
time clock to permit 24 hour per day operation. After
the desired temperature is reached, return the unit to
normal operation of 8–10 hours per day.
14
NOTE: If the pool pump and heat pump pool heater
shut OFF before the water temperature is raised to
the desired level, you must lengthen the running time
of both. To do this, reset the time clock dial for the
onger running time, or manually operate the pump
l
with the timer override switch. Since the unit capaci-
y and efficiency are both greater at higher ambient
t
air temperatures, run time should be set to take
advantage of all daylight hours, when the air is generally warmer.
• Is airflow through the unit being obstructed?
Restrictions such as shrubbery, tall grass, dirty
coils, or any other obstruction to airflow will reduce
performance.
• Is the pool blanket/cover being used?
Unblanketed 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.
C. CONDENSATION SEEMS EXCESSIVE
Heat pump pool heaters can produce a large amount
f condensation (water) during operation. If you sus-
o
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.
Service Call Verification
NOTE: The Raypak Service number is 800-260-2758.
Before you make a service call, first determine if the
problem is:
• Warranty Service
• 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.
• Unit operation (power supply, water flow, or time
clock adjustment)
NOTE: The MANUFACTURER IS NOT RESPON-
SIBLE for these adjustments.
Power Supply
• Verify that all circuit breakers are reset and working 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 circulating in the pool, verify that all valves are
positioned correctly.
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 system attached.
Time Clock Adjustment
Verify that the time clock is set to permit the unit to run
long enough to heat properly.

Fault Code Meaning of Code
OFF The desired programmed temperature point is lower than 60°F (15°C).
Shortage of refrigerant gas in the unit or faulty low pressure control. The unit will show
P & LP3
L
LP3) after 3 LP faults and shuts down the unit and pool pump for protection. If this
(
occurs, you should call for service.
HP & HP6
Low water flow in the unit or faulty high pressure control. Check water flow/backwash. The
unit will show (HP6) after 6 HP faults. This will stop the unit for protection.
Possible causes:
• The filter is in backwash position.
• The filter pump is stopped.
FLo & FL3
• The filter is dirty.
• Shortage of water to pool pump.
• Water pressure switch must be adjusted or it is broken.
• The unit is in the protection mode and will show (FL3), press any key to restart the unit.
FL3 code will stop the unit and pool pump.
FS
Unit is in the defrosting cycle.
(The fan works but the compressor is stopped.)
