Water Chemistry
(Corrosive water voids all warranties)
For your health and the protection of your pool e uipment, 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 isolat-
ed 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.
CAUTI N: 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.

service work is done with gauges and equipment
suitable for R-410A.

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
BTUH/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
cause of main heat loss, to a minimum, and will great-
ly reduce pool heating costs. uring 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.
• Recirculation of cold discharge air back into the
evaporator coil will greatly reduce the unit’s heat-
ing 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 unre-
stricted 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.
WARNING: 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.
WARNING: Do not install the unit within 3 ft of
fossil fuel burning heaters. Air inta e along the
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 blac rubber sound iso-
lation pads (each 2 inches square) that ship with
the unit. The pads are shipped in a bag with the
unions, gas ets and the I&O manual. Install pads
under the 4 corners of the unit to reduce vibra-
tion and sound transmission to the base.
CAUTI N: The unit’s supporting base must be high
enough to keep it completely free of standing water
at all times.
WARNING: This unit is designed for outdoor instal-
lation; DO NOT install it in an enclosed area such as
a shed or garage.

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 tempera-
tures can be encountered, drain the water circuit
to prevent possible freeze-up damage.
• For high wind installation requirements, refer to
the diagram on page 8.
Electrical Connections
Refer to the unit rating plate below the control panel for
precise power requirements for your unit, and for
ampacity and over-current protection requirements.
All wiring must be in accordance with the National
Electrical Code, NFPA No. 70, latest edition, and all
applicable state and local codes. Wiring diagrams are
located on pages 32 through 33.
• 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 up-
sizing requirements necessary due to wiring
distances. Always satisfy applicable codes and
standards.
• Electrical installation should be done by a licensed
electrician only.
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 19 of this manual, for installa-
tion information.
N TE: 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.

Water Connections
1. Connect the heat pump pool heater in the return
water line between the filter and the pool/spa. See
the lumbing Diagrams beginning on page 28.
2. Connect the filter outlet to the fitting marked
WATER IN at the bottom front of the unit.
3. Connect the fitting marked WATER OUT to the
return piping to the pool/spa. Unit inlet/outlet con-
nection fittings are 2-inch PVC unions.
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. In cold weather (freeze zone) areas, shutoff valves
(ball or gate type) must be installed at the unit inlet
and outlet to facilitate service and cold weather
drain-down.
5. Operate the pump and check the system for leaks.
6. rain plugs are located on each union fitting as
shown in Fig. 3 for draining the system during win-
terizing.

N TE: While it is possible to mount the upper union
with the drain plug vertically, Raypak has determined
that installing both unions with the drain plugs facing
down as shown in Fig. 3 provides for the best drain-
ing of the system.
CAUTI N: When the drain plugs are removed for
draining the system, ensure that they are stored in a
safe place for re-installation when needed to restart
the system.

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:
• MENU/SET – Scroll through available menus
and set changed values (MENU)
• U – Increase values in the Adjust menu
• DOWN – Decrease values in the Adjust menu
The display uses a 2-line, 16-character backlit Liquid
Crystal isplay (LC ) 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
minutes after any button press. Use the LC 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/COOL models, the options available by
pressing the MENU/SET (MENU) button are POOL
HEAT, POOL COOL, POOL AUTO, SPA, TIME SPA
and OFF. The cooling setpoint can be adjusted in the
range of 50F to the Cooling eadband value below the
Heating setpoint. This allows use in Plunge Pools.
Adjust the cooling setpoint accordingly.
The control board is equipped with a red status LE
on the back of the board which flashes at a “heartbeat”
of 2Hz while operating normally. The control board is
also equipped with a green LE (next to the commu-
nications jack) on the back of the board which will
flicker to indicate active communications when con-
nected to another system.
Upon initial application of power, the HPPH control
briefly sets all segments on the LC at power-up. On
a normal power-up, the control displays the current
software revision and the model type configuration
(HEAT ONLY, POWER EFROST or HEAT/COOL) on
the LC for 2 seconds and then resumes the user
selected mode it was in before power was interrupted.
The configuration for these units should be
HEAT/COOL.
Setpoints are read from non-volatile memory. If the
self diagnostic check indicates corrupted values,
“EEPROM Fault” is displayed on the LC 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
EFROST, or HEAT/COOL) before any device opera-
tion is enabled. Installation in these models requires a
model type of HEAT/COOL to be selected.
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) 3-way
valve control (Yes or No), (2) Pump control (Yes or No
and then what type of control – 4-speed control or vari-
able speed control), 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 each installation desires.
Once programming is completed, the control is ready
for operation.
WARNING: Install a check valve and/or a Hartford
loop AFTER the heat pump pool heater and
BEFORE any chlorinating devices. Install any auto-
matic chemical feeders AFTER the heat pump pool
heater. Improper installation of any type of auto-
matic chemical feeders can result in serious
damage to, or premature failure of, the heat
pump pool heater and will void the heat pump
pool heater warranty.

ods – factory default is 1. If a non-zero number of
pump periods is selected when the MENU button is
pressed, the control will prompt for On/Off times for
each of the selected number of pump periods.
Temperature Control
The control uses the appropriate Pool or Spa setpoint
as selected in the Operating mode. The heat demand
begins when the water temperature is 0.5F or more
colder (or 0.5F or more hotter in cooling mode) than
the setpoint.
Additional Features
Pump Control
The control is equipped to control the system pump
(particularly if it is a Raypak VSP pump). The control
provides for an output for a single speed pump (0.75A
@ 24VAC maximum) as well as an output for a vari-
able speed pump (10mA @12 V C). Four signals are
provided for selection of 4 discrete speeds for a vari-
able speed pump. The control can be configured to
provide a PWM signal on the speed1 output. The con-
trol will energize the pump at the requested speed for
each of the pump periods set in the program mode. If
a heat pump demand is present during a scheduled
pump operation, the pump runs at the override speed
(Speed 1) regardless of the scheduled speed. When
the pump is active because of scheduled operation
and there is no active heat demand, the control sets
the 3-ways valve outputs to the states set in the pro-
gram mode schedule.
Low Ambient ( utside) Lockout
The control is equipped with a Low Ambient Lockout
feature which will prevent the start of a new cycle if the
ambient temperature is lower than the programmed
value. This feature is accessed through the
Installer/Service Sub-menu as noted in Table , page
17. The default value is “OFF”, but the temperature
can be adjusted between 30F and 50F. This feature
can be enabled if it is desired to not operate the unit if
the temperature falls below this value. NOTE: This
feature will NOT stop the operation of an existing
cycle, it will only prevent operation of a new cycle.
An open outdoor temperature sensor (display will read
“Air Temp -46F”) will trigger an “Outside Lockout” error
if the Low Ambient lockout is enabled. An open or
shorted (display will read “Air Temp 282F”) outdoor
temperature sensor will also cause the control to shut
off the compressor regardless of if the Low Ambient
lockout is enabled.
Control Settings
The user can access these control settings by press-
ing and holding the MENU button for 5+ seconds. Any
changes to values are stored into the non-volatile
memory when the MENU button is pressed – which
also toggles to the next setting. Failure to press any
buttons for 60 seconds will cause the screen to revert
back to its previous operating mode screen. However,
the user mode can also be exited by pressing and
holding the MENU button for 5+ seconds.
If the control is in the temporary lockbox override when
the program mode is entered, the first prompt will be
“Reset PIN?”. The 2nd line will display “No”. Pressing
the UP or OWN buttons will toggle the 2nd line
between “Yes” and “No”. If the MENU button is
pressed while “Yes” is selected, the lockbox mode will
be cleared without needing to know the original PIN.
This step will be skipped if the control is not in the tem-
porary lockbox override mode.
Set Current Time
This allows setting of the current time. The time is fol-
lowed by an “A” or “P” for AM and PM respectfully. The
control has a 24-hour time clock – although it is NOT
a 7-day time clock. The time clock is used for control
of the pump periods.
C/F Display
This setting is used to define the units of measure for
all temperature readings. Fahrenheit is the default
value. You can change the setting to Celsius by tog-
gling the UP or OWN button and then pressing mode
to lock in the change.
Spa Max Temp
This setting is used to define the maximum tempera-
ture that the control can be set at for the Spa
operation. The range is 65F – 104F. The default value
is 102F.
Pool Max Temp
This setting is used to define the maximum tempera-
ture that the control can be set at for the Pool
operation. The range is 65F – 95F. The default value
is 80F.
Pump Periods
When the Pump Operation in the Installer’s Menu is
set to “4-Speed Enabled” or “Variable Enabled”, this
allows the setting of Pump Periods from this menu.
When setting this parameter, the control displays
“Pump Periods” on the first line of the display. The
number of pump periods (0 – 4) is displayed on the
center of the 2nd line. Pressing the UP or OWN but-

Control Lock Box Mode
The control is equipped with a Control Lockout feature
which is accessed by pressing and holding the MENU
and OWN buttons for 5 seconds. The user will be
prompted to enter a 3-digit code. A cursor flashes
under each digit in the 3 digit code when that digit is
being set. Pressing the UP or OWN buttons increas-
es or decreases the value and press the MENU button
to lock in that value. The cursor moves to the next digit
for setting. Once the last digit is selected (pressing
MENU) the display will ask to confirm the established
Lockout code. Pressing UP or OWN until “YES” is
shown and then press the MENU button to confirm this
Lockout code. NOTE: Record this Lockout code for
future reference.
Pressing any button when the control is in Lockout
Mode will prompt the user for the Lockout code. The
display will read “Control Lockout – Enter PIN 000”. If
the PIN is entered incorrectly, the display will show
“Invalid PIN”. Pressing any button will return the user
to the lockout code screen.
Entering the correct Lockout code will result in the dis-
play showing “Lockout Cleared” and the display will go
to the current operating state of the unit.
AUX Mode
The control has the capability to control two auxiliary
outputs for various external uses (rating is 0.75A @
24VAC max.). There are 4 selectable modes within
the Installer/Service Sub-menu for auxiliary mode con-
trol. These include: AUX OFF (default), AUX
OUTPUT, REMOTE OUT, and EXT HEAT. The control
allows setting ON and OFF times for these 2 auxiliary
outputs in the Installer/Service Sub-menu.
1. AUX OUTPUT – When AUX OUTPUT is selected,
the AUX1 and AUX2 outputs turn ON/OFF from the
time schedule loaded into the control at installa-
tion. Time schedules for each output are
independent of each other. If the OFF time is
before the ON time, the control will assume the
Aux output is to be energized over midnight. If the
time of day is not known due to a clock failure, the
AUX output schedules are not run.
2. REMOTE OUT – When REMOTE OUT is select-
ed, the AUX1 output is used to control another pool
heater. The AUX1 output energizes 10 seconds
after the first unit compressor and de-energizes
when the first unit compressor de-energizes.
AUX2 output is always off in this configuration.
3. EXT HEAT – When EXT HEAT is selected, AUX1
output is energized whenever there is a 1st stage
heat demand. This allows the use of a solar sys-
tem in conjunction with this unit and the control will
operate the solar system first and only bring this
unit on if the heating demand is NOT being met by
the solar system. AUX2 is always off in this con-
figuration.
The 2nd stage (HPPH) demand is initiated when
water temperature has remained more than 0.5F
colder than the heat setpoint for more than 2
hours, or when the water temperature is 1.5F or
more colder than the heating setpoint.
Remote Pool peration
The control displays “Remote Pool” on the first line of
the display while the 2nd line displays “Cool”, “Heat” or
“Auto”. Pressing the UP or OWN buttons toggles
between these values. Factory default is “Cool”. The
control uses the value selected when the MENU but-
ton is pressed to advance to the next item.
Pool Auto Mode
The control is equipped with a mode which will auto-
matically heat and cool the pool within the range of the
heating setpoint plus the Cooling eadband (2-10F
adjustable – default 6F) established in the
Installer/Service Sub-menu.
Fault History
The control is equipped to maintain fault history in the
Installer/Service menu. It will retain the last 10 faults
(starting with the most recent). If the fault history
exceeds 10 events, the earliest fault drops off when a
new fault occurs. NOTE: There is no time/date stamp
associated with each fault. This history is intended to
simply show what faults the unit has experienced.
When the “Faults Last” shows on the display, pressing
the UP button toggles to the most previous fault.
Pressing the UP button toggles through the recorded
faults. The faults are labeled on the first line of the dis-
play as Faults Last, Faults 2, Faults 3, etc.
Consecutive identical faults are only stored once.
Run Hours/Cycles
The control is equipped to monitor the number of run
hours of the unit and the cycles of operation. This is
accessible through the Installer/Service menu. These
values are not resettable. The “Run Hours” tracks the
number of hours that the compressor has been ener-
gized. This data is stored in non-volatile memory each
time the demand for heat is satisfied. Hours and min-
utes are stored, although only hours are displayed.
The “Cycles” tracks the number of times that the com-
pressor has been energized.

20
Compressor Start Delay
The control is equipped with a compressor start delay
to prevent short-cycling of the compressor. The con-
trol will not energize a compressor unless the
compressor has been off for at least 3 minutes. When
this situation arises, the display shall read “Comp Start
elay” until the timer clears and the compressor starts.
Minimum Run Time
To ensure proper operation of the compressor and
longest life, the control has a minimum run time for the
compressor of 3 minutes. If the setpoint is reached
within 3 minutes, the compressor will continue to run
for 3 minutes unless (1) the high pressure switch trips,
(2) the water pressure switch trips, (3) the high tem-
perature limit is reached, or (4) the user selects “OFF”
mode.
Defrost peration
The control is equipped with several defrost algorithms
depending on the configuration of the unit (HEAT
ONLY, POWER EFROST or HEAT/COOL).
On this HEAT/COOL model, the control initiates a
defrost cycle based on a programmed algorithm
involving current and baseline ambient temperatures,
and current and baseline coil temperatures when the
coil temperature drops below the “ efrost Temp” set in
the Installer/Service sub-menu. Factory default is 24F.
The control shuts off the fan and activates the revers-
ing valve so the hot refrigerant gas is directed to the
coil to defrost the coil. When the coil sensor sees tem-
peratures above the “ ef Terminate” value set in the
Installer/Service sub-menu, the unit returns to normal
operation.
3-Way Valve Control
The control is equipped to control system 3-way
valves. The control will set the 3-way valves to the
state requested when there is an active thermostat
demand for spa heat, pool heat or pool cool. This
takes priority over positions requested by Pump
Schedule operations. If the control also controls the
pump, the pump will shut off for 30 seconds before the
valves change state so as to not have to fight pump
head pressure during change of position. uring this
change, the display will show “Valve Chng elay”.
The 3-way valves are field installed to the #38-40 &
#41-43 terminals on the terminal strip inside the junc-
tion box of the unit. The initialization of the 3-way
valves is set in the Installer/Service sub-menu.
If the water pressure switch (or water flow switch) is
closed when the control needs to change the 3-way
valve position, the control displays “WPS Closed” and
waits indefinitely with the pump and compressor off
until the water pressure switch (water flow switch)
opens. After it senses the open switch, the control
switches the 3-way valves and resumes normal oper-
ation.
If no thermostatic demand is requesting operation and
the pump is being run from scheduled pump periods,
the control sets the 3-way valves to the states request-
ed in the pump period mode schedule.
When there is no demand for pump output because of
manually selected OFF mode, no thermostat demand
or no scheduled pump period, the control leaves the 3-
way valves in their last commanded state. Valve
outputs will not change until there is an active request
for them to be in a different state.
The rating of the control contacts is 0.75A at 24VAC
maximum.
Battery Back-up
The control is equipped with a battery to maintain con-
trol settings through power outages. This is located on
the upper right rear corner of the control. Replace as
necessary with a BR2032, 3V battery.
High Water Temperature Limit
The control is equipped with a high water temperature
limit which will shut off operation of the compressor if
either temperature sensor reads at or above 108F
(41C). The display will read “Hi Water Temp”. The
compressor will remain locked out until both sensors
are below 103F (40C) and the user presses the UP
button. The high temperature limit is active in all
modes of operation.
High Pressure Switch Lockout
If the high pressure switch opens, the control de-ener-
gizes the compressor output and the fan continues to
run for 15 minutes after the HPS opened and the dis-
play will show “Hi Press Trip”. If the high pressure
switch trips 7 times in a single cycle, the display will
show “Hi Press Lockout” and the unit will be locked out
of operation for 4 hours. The unit will automatically
reset after 4 hours or the lockout can be manually
reset by pressing the MENU button or cycling the
power. The high pressure switch must close for 3 sec-
onds for the control to recognize it as closed.
Low Pressure Switch Lockout
The control ignores an open low pressure switch for
the first 30 seconds after the compressor is energized.
If the low pressure switch opens for 3+ seconds any
time after this 30 second period, the compressor will
shut down and “Lo Press Trip” will show on the display.
