Water Chemistry
(Corrosive water voids all warranties)
For your health and the protection of your pool equipment, it is essential that your water be chemically
balanced. The following levels must be used as a guide for balanced water.
• Occasional chemical shock dosing of the pool or spa water should not damage the heater providing
the water is balanced. However, it is highly recommended that the heat pump pool heater is isolated
via shut off valves before any aggressive chemical treatment.
• Automatic chemical dosing devices and salt chlorinators are usually more efficient in heated water.
Unless controlled, they can lead to excessive chlorine level which can damage your heater.
• Further advice should be obtained from your pool or spa builder, accredited pool shop, or chemical
supplier for the correct levels for your water.

Warnings — Pay Attention to These Terms
This manual, as well as the pool/spa heat pump pool heater itself, contains ANSI-approved product safety signs
and labels. Please read these signs and labels, as they convey important safety information about hazards that
may be potentially present in and around the heat pump pool heater.
CAUTIO : Elevated water temperature can be
hazardous. he U.S. Consumer Product Safety
Commission has these guidelines:
1. Spa water temperatures should never exceed
104°F (40°C). A temperature of 100°F (38°C) is
considered safe for a healthy adult. Special cau-
tion is suggested for young children.
2. Drinking of alcoholic beverages before or during
spa or hot tub use can cause drowsiness which
could lead to unconsciousness and subsequently
result in drowning.
3. Pregnant Women Beware! Soaking in water over
102°F (39°C) can cause fetal damage during the
first three months of pregnancy resulting in the
birth of a brain-damaged or deformed child.
Pregnant women should stick to the 100°F (38°C)
maximum rule.
4. Before entering the spa or hot tub, users should
check the water temperature with an accurate
thermometer; spa or hot tub thermostats may err
in regulating water temperatures by as much as
4°F (2.2°C).
5. Persons with a medical history of heart disease,
circulatory problems, diabetes, or blood pressure
problems should obtain a physician's advice
before using pools or hot tubs.

Introduction
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 per-
formance.
This heat pump pool heater is an extremely efficient,
economical machine designed specifically for swim-
ming 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
TUH/hr basis. As a result, it will be required to oper-
ate 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
main 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.
Installation Considerations
Situate the heat pump pool heater carefully to mini-
mize 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.
• This unit features an ‘up-flow’ discharge for quiet
operation. Air is pulled up through the evaporator
coil and discharged through the top grille. Allow at
least 5 ft (1.5 m) clearance above the unit for unre-
stricted air discharge. D N T install the unit
under a porch or deck. Refer to Fig. 1.
Recirculation of cold discharge air back into the
evaporator coil will greatly reduce the unit’s heat-
ing capacity and efficiency.
• To minimize water piping, locate the unit as close
as possible to the existing pool pump and filter.
• Irrigation water should be directed away from the
heat pump pool heater - irrigation water spray can
damage the heat pump pool heater.
• Rain water run offs- the unit is designed to operate
outdoors and can be exposed to rain. However,
rain water run off falling directly onto the unit can
cause damage and/or shorten the life of your unit.
This may also void your warranty. Install rain gut-
ters or rain diverters on your roof if the unit is
installed in a position where contact with rain run
off may occur.
WAR I G: This pool/spa heat pump pool heater is
an electromechanical machine that incorporates a
pressurized refrigerant gas in a sealed system.
ONLY trained and qualified service personnel are
authorized to install or service this equipment.
Without proper training and knowledge of such
equipment, any attempt to install or service the unit
could result in serious injury or even death.
WAR I G: D n t install the unit within 3 ft f
fssil fuel burning heaters. Air intake al ng the
sides f this heat pump p l heater c uld disturb
the c mbusti n pr cess f the unit, and c uld
cause damage r pers nal injury.
• M unt the unit n a level, sturdy base, preferably
a concrete slab. The size of the base should be at
least 3 ft by 3 ft - slightly larger if hurricane tie down
straps are installed. See page 8 for more details.
CAUTIO : The unit’s supporting base must be high
enough to keep it completely free of standing water
at all times.
WAR I G: This unit is designed for outdoor instal-
lation; D N T install it in an enclosed area such as
a shed or garage.
OTE: Hurricane tie down brackets, tie down
screws, 2 x union halves, 2 x 45-degree PVC
elbows, the printed warranty and the I&O manual are
located in an accessory box mounted on the pallet
beside the heater inside the packaging. DO NOT
throw away without removing all components.

Fig. 1: Installation Clearances
• 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 tempera-
tures can be encountered, drain the water circuit
to prevent possible freeze-up damage. Refer to
Freeze Protection section on pg. 33 for proper pro-
cedures.
• If the location of the HPPH is below the water line
of the pool, the Water Pressure Switch (WPS) or
Water Flow Switch (WFS) might need to be adjust-
ed or an external WFS might be needed.
• For high wind installation requirements, refer to
the Fig. 3 on page 8.

OTE: Refer to the National Electrical Code, Article
680, for general requirements for swimming pools
and equipment, and to Article 440 for special consid-
erations necessary for circuits supplying hermetic
refrigeration motor/compressors.
WAR I G: This unit MUST be installed using flex-
ible conduit for supply wiring to the unit. This will
allow movement of the conduit whenever the junc-
tion box is removed for service - see instructions on
page 38.
This unit is pre-wired to work with external control sys-
tems, heat-on-demand options and other external time
clock overrides. Refer to the external control system’s
instructions, and page 29 of this manual, for installa-
tion information.
An earth ground lug is located to the right side of the
water connections.
Water Connections
1. Connect the heat pump pool heater in the return
water line between the filter and the pool/spa. See
the Plumbing Diagrams beginning on page 40.
2. Connect the filter outlet to the fitting marked
INLET/ENTREE at the bottom front of the unit.
3. Connect the fitting marked UTLET/S RTIE to
the return piping to the pool/spa. Unit inlet/outlet
connection fittings are 2-inch PVC unions.
CAUTIO : The heat pump pool heater inlet and
outlet connections are N T interchangeable. They
must be connected as instructed below.
OTE: The earth ground lug may be relocated to
the left side of the water connections as needed dur-
ing unit installation.
WAR I G:Improper installation of any type of
automatic chemical feeders can result in serious
damage to, or premature failure of, the heat
pump pool heater and may void the heat pump
pool heater warranty. Install a check valve and/or a
Hartford loop AFTER the heat pump pool heater and
EFORE any chlorinating devices. Install any auto-
matic chemical feeders AFTER the heat pump pool
heater.

HPPH Control Display
The HPPH display is viewable from outside of the
heater. All operation and settings of the HPPH control
are accomplished through the use of the 3 buttons of
the user interface. These buttons are labeled as fol-
lows (see Fig. 5):
• MENU/SET – Scroll through available menus
and set changed values (MENU)
• UP – Increase values in adjustible menus
• D WN – Decrease values in adjustible menus
The display uses a 2-line, 16-character backlit Liquid
Crystal Display (LCD) as the method for supplying
information. The backlight is normally off. The back-
light is on for 15 minutes after Power-Up and for 15
Water connections from the unit to the main return
line can be PVC pipe or flexible pipe approved for
the purpose and, in either case, should be at least
equal in size to the main pool/spa circulation pip-
ing.
4. Shut Off/Diverter valves, preferably three-way
valves which allows for a bypass route, on the
inlet and outlet lines of the HPPH are required if:
- water flow to the unit will exceed 60gpm
- to protect (completely bypass) the unit from
any harmful chemical treatments (i.e. Acid
wash, back-to-back super chlorinators, stain
treatments, etc.); or
- to be able to isolate the unit for
service/repair or freeze preparation and still
allow pool/spa circulation to continue
Please refer to the plumbing diagrams, starting on
pg. 40, for further instruction.
Please note that some municipalities do not allow
the use of a shut off valve on the effluent/outlet
side of any heating equipment, especially when
there is one on the inlet side. These entities typi-
cally instead allow a PVC tee and spring check
valve on the effluent/outlet side. This is allowed by
Raypak and can also double as your protection
from chemical feeders & chlorinators that our
downstream of the unit.
5. Operate the pump and check the system for leaks.
6. Drain plugs are located on each union fitting as
shown in Fig. 4 for draining the system during win-
terizing.

with the drain plug vertically, the manufacturer has
determined that installing both unions with the drain
plugs facing down as shown in Fig. 4 provides for the
best draining of the system.

minutes after any button press. Use the LCD to setup
and monitor the operation of your heater.
If the membrane switch remains inactive for 180 sec-
onds (3 minutes), the screen will revert to the current
view.
On HEAT ONLY and POWER DEFROST models, the
options available by pressing the MENU/SET (MENU)
button are POOL HEAT, SPA, TIMED SPA and OFF.
On HEAT/COOL models, the options available by
pressing the MENU/SET (MENU) button are POOL
HEAT, POOL COOL, POOL AUTO, SPA, TIMED SPA
and OFF. The cooling setpoint can be adjusted in the
range of 50F to the Cooling Deadband value below the
Heating setpoint. This allows use in Plunge Pools.
Adjust the cooling setpoint accordingly.
Upon initial application of power, the HPPH control
briefly sets all segments on the LCD at power-up. On
a normal power-up, the control displays the current
software revision and the model type configuration
(HEAT ONLY, POWER DEFROST or HEAT/COOL) on
the LCD for 2 seconds and then resumes the user
selected mode it was in before power was interrupted.
Setpoints are read from non-volatile memory. If the
self diagnostic check indicates corrupted values,
“EEPROM Fault” is displayed on the LCD and opera-
tion is prohibited until setpoints are manually set.
If unit type has not been set (like during the replace-
ment of the HPPH control), the control prompts the
user to set the model type (HEAT ONLY, POWER
DEFROST, or HEAT/COOL) before any device opera-
tion is enabled.
Fig. 5: HPPH Control Display

Upon initial installation, there are several items that
must be defined and programmed depending on the
configuration and accessories intended to be con-
trolled by the HPPH control. These include: (1) Pump
control (Yes or No and then what type of control – 4-
speed control or variable speed control), (2) 3-way
valve control (Yes or No), and (3) Auxiliary control (Yes
or No and then what type – External Heat, Auxiliary
Output or Remote Output).
Once these choices are made, then additional infor-
mation relating to the establishing of pump periods,
pump speeds during each period and Return/Suction
Valve positions during each period must be deter-
mined and set in the control.
The options for the control can be very simple or very
detailed, depending upon the needs of the installation.
Once programming is completed, the control is ready
for operation.
The user may select one of several operating modes.
Each mode is selected by pressing the MENU (button
is labeled MENU/SET, but MENU is used in these
instructions for simplicity) button to cycle between the
modes. Each press of the MENU button selects the
next mode. There is no automatic increment from con-
tinually pressing the MENU button. In fact, continually
pressing the MENU button (for 3+ seconds) will move
the user into the USER Menu.
User Modes
For HEAT ONLY and POWER DEFROST models, the
mode selections are:
OFF – POOL HEAT – SPA – TIMED SPA.
On HEAT ONLY and POWER DEFROST models,
there are additional operational modes available as
noted below:
1. When POOL HEAT mode is selected, each press
of the UP or DOWN buttons will increase /
decrease the pool heating setpoint temperature.
Holding the UP or DOWN buttons down will speed
up the change of the temperature values.
2. When SPA mode is selected, each press of the UP
or DOWN buttons will increase / decrease the spa
setpoint temperature. Holding the UP or DOWN
buttons down will speed up the change of the tem-
perature values.
3. When TIMED SPA mode is selected, the display
will read “Up or Dn to Set”. This tells the user to
press the UP or DOWN buttons to set the desired

12
increments. The timer will start and the unit will
begin heating as necessary to maintain the Spa
setpoint temperature for this duration. At the end of
the timed period, the unit will automatically go to
the last operational state (POOL HEAT, POOL
COOL, POOL AUTO, SPA, or OFF). Once the unit
turns on, the display will toggle between the cur-
rent Spa water temperature and the current
operating state (“Heating” for example). Pressing
the MENU button will change the display to show
the time remaining on the timer. Press the MENU
button again to go back to the current status.
The control saves the setpoint changes in non-volatile
memory and begins using them for heat demand
decsions after both the UP and DOWN buttons have
been released for 2+ seconds.
