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.

Recommended Level(s) Fiberglass Pools Fiberglass Spas Other Pool & Spa Types

Water Temp. (Deg. F) 68 to 88 89 to 104 68 to 104

pH 7.3 to 7.4 7.3 to 7.4 7.6 to 7.8

Total Alkalinity (PPM) 120 to 150 120 to 150 80 to 120

Calcium Hardness (PPM) 200 to 300 150 to 200 200 to 400

Salt (PPM)

Free Chlorine (PPM)* 2 to 3 2 to 3 2 to 3

Total Dissolved Solids (PPM)

*Free Chlorine MUST NOT EXCEED 5 PPM!
** In salt water chlorinated pools, the total TDS can be as high as 6000ppm.

• Occasional chemical shock dosing of the pool or spa water should not damage the heater providing
the water is balanced.

• 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.

or substantial property damage if ignored.

WARNING:

CAUTION:

NOTE:

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.

CAUTION: Elevated water temperature can be
hazardous. The 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 cau­tion 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.

Indicates the presence of hazards or unsafe practices which could cause severe personal
injury, death or substantial property damage if ignored.

Indicates the presence of hazards or unsafe practices which could cause minor personal
injury or product or property damage if ignored.

Indicates special instructions on installation, operation, or maintenance which are important
but not related to personal injury hazards.

CAUTION: Improper chemical content in a swim­ming pool or spa can damage the heat pump pool
heater. DO NOT add pool chemicals to the skimmer.
This will damage the heat pump pool heater and
could void the heat pump pool heater warranty.
ALWAYS follow the product manufacturer’s direc­tions when adding any chemicals to your pool.

WARNING: These heat pump pool heaters are
charged with R-410A refrigerant. Ensure that all
service work is done with gauges and equipment
suitable for R-410A.

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.

Operating Instructions

The electronic board has the capability of memorizing
two different programmed temperature settings as fol-

ows (refer to Fig. 5):

l

For a pool, maximum 95°F (35°C)

•

• For a spa, maximum 104°F (40°C)

Controls

Your heat pump pool heater incorporates digital safety
controls and indicators to ensure its safe, reliable
operation.

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.

To Select Pool or Spa Mode

To have access to either one of these programs, press
the SET key until you see P _S and by pressing the
UP or DOWN key you can switch to POL or SPA.

To Increase the Desired Water
Temperature (Pool or Spa Mode)

Push the SET key until you see POL or SPA. The pro­grammed temperature will be displayed. Press the UP
arrow to increase the temperature setting one degree
at a time.

To Lower the Desired Water
Temperature (Pool or Spa Mode)

Push the SET key until you see POL or SPA. The pro­grammed temperature will be displayed. Press the
DOWN arrow to decrease the temperature setting one
degree at a time.

Once the control has been programmed to the desired
pool water temperature, the programmed temperature
will be displayed for approximately 5 seconds. Then
the digital display will display the actual pool water
temperature.

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 (5.5°-8.8°C) 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.

To make the Board a Pool ONLY Board, call 800­260-2758 for instructions.

To Select Temperature in °C or °F

Press the SET key until you see F _C. By pressing the
UP or DOWN key you can switch to °F or °C. Once the
temperature display mode has been programmed it
will be displayed for approximately 5 seconds, then
the digital display will return to the actual pool water
temperature in the mode that you have chosen.

10

Heat/Cool Operation

he Raypak Professional models come standard with

T
heat/cool operation. The heat/cool model is designed
to both heat and cool the pool. To select heat or cool
mode, push the SET key until H/C is displayed. Press
the DOWN arrow key to select heating (hea), or the
UP arrow key to select cooling (col). Set the desired
setpoint temperature as described earlier in this man­ual.

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.

NOTE: Once the control has been programmed to
the desired pool water temperature, the pro­grammed temperature will be displayed for
approximately 5 seconds. The digital display will
then show the actual pool water temperature.

NOTE: Remove the pool/spa blanket and turn on
any fountains, sprays or other water features to
speed cooling.

When the unit has been operating in the heating mode
for a few minutes, the discharge air temperature
should be 8°–10°F (4.5°–5.6°C) cooler than the air
entering the unit.

When the unit has been operating in the cooling mode
for a few minutes, the discharge air temperature
should be 8°–10°F (4.5°–5.6°C) warmer than the air

entering the unit.

NOTE: Heating is more efficient during warmer day­light hours and cooling is more efficient during cooler
night time hours.

1. Remove leaves, pine needles, etc., from the evap-

orator 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.

3. Backwash or otherwise clean the pool filter. If nec-

essary, 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.

System Start-Up

1. Verify that the Digital Board is displaying a temper­ature and the pool pump is running and water is
circulating properly.

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 (4.5°–5.6°C) cooler than the air
entering the unit. If not, see the Troubleshooting
Section.

Summer Shutdown

If you do not plan to use the heat pump pool heater
during the summer months, secure and protect it as
follows:

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.

11

Freeze Protection

Cabinet Care (optional)

f the unit is installed in a location subject to freezing

I
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.

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.

Maintenance

NOTE: The heat pump pool heater MANUFACTUR-

ER IS NOT RESPONSIBLE for maintenance
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

The stainless steel cabinet is designed for harsh out­door use and requires little care. However, you can
clean it if you wish.

WARNING: Shut OFF electricity to the unit before

leaning.

c

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.

Troubleshooting

If your unit does not operate, or simply does not heat
your pool water, Fault Codes on the front control
panel, can provide valuable clues as to what is wrong,
and may even indicate precisely what the problem is.
Always observe these codes before calling a service
representative. By reporting on the telephone the Fault
Codes that are showing, the service rep may be able
to solve the problem without the expense of a service
call.

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. Check the operation of the flow
switch.

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.

• Is the ejected air from the unit 8°–10°F

(4.5°–5.6°C) 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 inter-

nal 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.

12

• 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?

emember that the heat pump pool heater only

R
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.

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 unit 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.

• 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.

• 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?

• Is the Heat Light ON? If not, then the thermostat
setting is not higher than the temperature of the
water. Raise the thermostat setting.

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.

C. CONDENSATION SEEMS EXCESSIVE

Heat pump pool heaters can produce a large amount
of condensation (water) during operation. If you sus­pect 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.
For units in Canada, call 800-268-6966.

Before you make a service call, first determine if the
problem is:

• Warranty Service

• Unit operation (power supply, water flow, or time

clock adjustment)

NOTE: The MANUFACTURER IS NOT RESPON-
SIBLE for these adjustments.

B. UNIT IS NOT RUNNING

• Is the temperature display 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.

• 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.

Power Supply

• Verify that all circuit breakers are reset and work­ing properly.

• If the temperature display 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.

13

Time Clock Adjustment

Verify that the time clock is set to permit the unit to run long enough to heat properly.
