Thank you for buying
a HEATPRO pool heat pump.
The HEATPRO pool heat pump is a self-contained unit designed specifically for
pool heating. Each component has been selected with care to achieve a high-
quality product in an effort to exceed all industry standards.
All HEATPRO pool heat pumps have an electronic board with service
analyzer, a titanium heat exchanger tube warranted for 10 years against
corrosion and a UV-resistant plastic cabinet that eliminates all maintenance
for life. All components are of superior quality, which presents you with an
effective, state-of-the-art technology heat pump.
Compared to other types of pool heaters, such as gas or oil-fired, the
HEATPRO pool heat pump has a lower heating capacity on a BTU/hr
basis. Therefore, it needs to operate for a longer time to accomplish the
desired results. Occasionally, it may be necessary to run the heat pump for
up to 24 hours per day. However, this should not be of concern to the owner
because the heater is designed to operate continuously. What’s more, despite
continuous operation, it will still heat the pool far more economically than other
types of heaters.
As with all pool heaters, you are advised to use a pool cover at night and when
the pool is not in use. The pool cover should be used if night temperatures are
15°F less than desired pool temperature. This will keep evaporation, the greatest
source of heat loss, to a minimum, thus greatly reducing the overall pool heating
costs. During warmer weather, the pool cover may not be required.

CAUTION
All electrical connections must be done by a qualified electrician and
according to the local electrical codes. Always cut off the unit’s main
power whenever the access panel is open or removed. Always install the
machine outdoors (unless otherwise approved by the manufacturer),
while respecting the minimal clearances needed for proper operation
and heating.
!
CAUTION
Proper pool chemistry is vital to the life of your heater. Pay particular
attention to the total alkalinity and TDS. It is highly recommended that you
have your pool chemistry checked often by an independent pool store.

OWNER’S MANUAL

Installation Instructions
Location
The placement of the pool heater is very important in keeping installation
costs to a minimum while providing for maximum efficiency of operation, as
well as allowing adequate access for service and maintenance.
The pool heat pump is designed for outdoor installation and should
not be installed in a fully enclosed area, such as a shed, garage, etc.
Recirculation of cold discharged air back into the evaporator coil will greatly
reduce unit heating capacity and efficiency.
The unit should be located as close as practical to the existing pool pump and
filter to minimize water piping. However, do not forget to provide a 24”clea-
rance at the very least all around your heat pump. The use of 90 degree bends
and short radius elbows in the water piping should be kept to a minimum.
Mount the unit on a sturdy base, preferably a concrete slab or a set of blocks.
The base should be completely isolated from the building foundation wall to
prevent the possibility of sound or vibration transmission into the building.
The size of the base should not be less than 36” x 36” (92 cm x 92 cm).
Air is pulled through the evaporator coil and
discharged through the top grille. A minimum
clearance of 72 inches should be allowed above
the unit for unrestricted air discharge. The unit
must not be installed under a porch. Any side of
the unit should be located at least 24 inches from a
wall or from any other obstruction for unrestricted
air intake and service access.

Water piping
The piping sequence is as follows: pool > pool pump > filter > heater > check
valve > chemical feeder > pool. Automated chlorine distribution systems, if
used, must be placed downstream of the heater to minimize harm to the pool
equipment. Use rigid PVC piping if possible (SCH40 or SCH80). All joints
should be glued with PVC glue. When the piping installation is complete,
operate the pool pump and check the system for leaks. Then, check the filter
pressure gauge to verify that there isn’t any indication of excessive pump
head pressure.
You can also make the connections using high-pressure flexible hose, but
make sure the hose can withstand high pressure. The installation of a heat
pump bypass is not necessary unless the water flow exceeds 75 GPM.
Note: Certain installations have valves which isolate the heat pump from the water circuit. If the heat exchanger
is deprived of water circulation for several days, high chlorine gas could cause excessive corrosion. If the disconnect
switch is turned off, be sure that the pool water is allowed to circulate through the unit, or is drained out of it.
Electrical
The wiring of your pool heat pump should be performed by a qualified
electrician in accordance with local requirements.
A properly-sized breaker and copper wire must be used.
Check the heat pump data label for required maximum breaker size.
The unit must always be powered off before opening the access panel.

OWNER’S MANUAL

Bonding
Because all metals have different electrical potentials, all metal and electrical
components of the pool system must be bonded together. This includes the
metal framework of the pool, the light, the pump, the filter (if made out of metal),
the heater, any automatic chlorine generator, and any other metal or electrical
equipment. On some older pools, this substructure bond wire may not exist.
In these cases, a 6 to 8 foot solid copper rod must be driven into the ground
near the equipment. All electric and metal components must then be bonded
to each other, and then to the copper rod.
CAUTION
!
1. A 1/3 lb check valve must be installed between
the heater and any automatic chlorine distribution
system (if used).
2. Any kind of automatic chlorine distribution system
must be installed after or downstream of the heat
pump.
3. The filter must be placed before or upstream from
the heat pump.
4. A bypass and shut-off should be installed on
all systems for ease of service, maintenance and to
balance the water flow. Bypasses must be installed
on any system with over a 3/4 HP pool pump.
(see FIG.3 for bypass plumbing)

Using an External Controller
To connect the electronic board in order to control it remotely, use the P_S
terminals on the right side of the board. Next, access the P_S menu and se-
lect the desired mode. In internal mode, POOL or SPA mode can be adjusted
by using this menu. In external mode, a normally open contact puts the board
in POOL mode and a closed contact puts the board in SPA mode. Therefore,
a board set to OFF in POOL mode and to 80 degrees in SPA mode can be
controlled with an external switch to heat up to 80 degrees.
Internal mode: Use the P_S mode on the main menu
External mode: • Open contact = POOL mode
• Closed contact = SPA mode
Control using a switch
To control the board using an external switch, follow these steps :
• Turn on the heat pump.
• Set POOL mode to OFF.
• Set SPA mode to the desired temperature.
• Access the setup menu.
• Select mode E (external) on the P_S menu.
• Run two J7 (P_S) terminal wires from the HPEC-003 board to the NO
switch terminals (see FIG.4).
• You can now control the operating mode by turning off the switch
(open = POOL, closed = SPA.)

OWNER’S MANUAL

Initial Startup
Before starting the pool heater for the first time, it is important to verify that
the breaker is in the ON position.
Also make sure that the water circulates freely and that the pool pump is activited.
Then, you will need to set the water temperature you desire. The fan will
immediately start. The compressor will start after a 3 to 4-minute delay.
When the compressor is running, the HEATING/CHAUFFAGE indicator located
on the right (see “Service Analyzer Control,” p. 13) should be lit. At initial startup,
it is normal for the unit to run 24 hours a day.
It is also normal to see water dripping from the holes at the base of the unit.
This is just condensation.
