Important Safety
Instructions

READ AND FOLLOW ALL
INSTRUCTIONS.

Safety Guidelines

This manual contains information that
is very important to know and
understand. This information is
provided for SAFETY and to PREVENT
EQUIPMENT PROBLEMS. To help
recognize this information, observe the
following symbols.

Warning indicates

a potentially
hazardous situation which, if not
avoided, could result in death or
serious injury.

Caution indicates

a potentially
hazardous situation which, if not
avoided, may result in minor or
moderate injury.

Notice indicates

important
information, that if not followed, may
cause damage to equipment.

Operating Instructions

• The water in a pool or spa should
never exceed 104ºF (40ºC). A water
temperature in excess of 104ºF is
considered unsafe for all persons.
Lower water temperatures are
recommended for extended use
(exceeding 10-15 minutes) and
young children.

• Excessive water temperatures have
a high potential for causing fetal
damage during the early months of
pregnancy. Pregnant or possibly
pregnant women should limit pool
or spa water temperatures to 100ºF
(38ºC).

• Alcohol, drugs, or medication
should not be used before or during
pool or spa use since their use may
lead to unconsciousness with the
possibility of drowning.

• Obese persons and persons with a
medical history of heart disease, low
or high blood pressure, circulatory
system problems, or diabetes should
consult a physician before using a
pool or spa.

• Persons using medication should
consult a physician before using a
pool or spa since some medication
may induce drowsiness while other
medication may affect heart rate,
blood pressure, and circulation.

• Prolonged immersion in hot water
may induce hyperthermia.
Hyperthermia occurs when the
internal temperature of the body
reaches a level several degrees
above the normal body
temperature of 98.6ºF. The
symptoms of hyperthermia include
dizziness, fainting, drowsiness,
lethargy, and an increase in the
internal temperature of the body.
The effects of hyperthermia
include: unawareness of impending
hazard; failure to perceive heat;
failure to recognize the need to exit
pool or spa; physical inability to exit
pool or spa; fetal damage in
pregnant women; and
unconsciousness resulting in a
danger of drowning.

• Because the tolerance of water
temperature-regulating devices
may vary as much as ±5ºF (±3ºC),
you should measure the water
temperature at several locations
using an accurate thermometer
before entering a pool or spa.

SAVE THESE INSTRUCTIONS.

Pool Chemistry and Warranty (PRO400 & PRO600)

Maintaining pool chemistry at
the correct levels is critical for
health and pool/spa equipment
reasons. Failure to maintain
industry recognized standards
for proper pool chemistry will
void your warranty on the

PRO400 & PRO600. This chart

contains the recommended
levels for a typical pool. If you
have questions about
maintaining your pool and its
chemistry, consult your local
APSP/NSPI pool professional or
call 877-278-2797 to talk to an
AquaPro representative.

Installation
Procedures

Unit Inspection

Inspect your unit very carefully before
installing. Make sure there has been no
damage to the evaporator fins or there
are no punctures or oil-soaked areas on
the box. This would indicate damage to
the refrigeration system and should be
rejected immediately.

THE UNIT MUST BE TRANSPORTED IN
THE UPRIGHT POSITION AT ALL
TIMES AND MUST NOT BE DROPPED
OR TAILGATED. DAMAGE TO THE
UNIT DURING TRANSPORTATION IS
NOT THE RESPONSIBILITY OF THE
MANUFACTURER.

Unit Location

Once the unit has been inspected and
cleared of any transportation damage,
it is now time to locate the pool
heater. It is very important to
understand the location of the unit for
the best performance of operation.

See Figure 1 for location
recommendations.

A minimum of 18” of clearance
between the evaporator coils and
shrubs, fences, walls, etc. must be
maintained for adequate air intake.

A minimum of 5’ of vertical clearance
between the top of the unit and any
roof overhang or other obstructions
must be maintained in order to
prevent the re-circulation of cold air
back into the evaporator coils. This is

to maintain the efficiency of the unit.
A minimum of 36” of clearance

between the front of the unit (access
panel area) and any obstruction must
be maintained to allow maintenance
on the unit when necessary.

The unit should be located on a solid
level surface, a minimum of 36”x 36”
for proper drainage.

Make sure any sprinkler heads are not
directly spraying water on the unit.
While heat pumps are made for an
outdoor environment, they are not
designed to have sprinkler water
constantly spraying them. NOTE: This

type of constant watering directly
on the unit can void your warranty.

Condensation drain holes are provided

3

in all units for adequate removal of
condensation and rainwater. ALL

UNITS WILL HAVE CONDENSATION.
THIS SHOULD NOT BE MISTAKEN
FOR A LEAK IN THE UNIT.

Plumbing

Where freezing weather is encountered,
the detachable connection/union
(provided on PRO1000) must be installed
immediately adjacent to the heater to
facilitate servicing and draining of the
heat exchanger. Draining is necessary

to prevent damage to the condenser
shell and coil due to the expansion
of freezing water.

The minimum water circulation
capacity flowing through the pool
heater is 25 gallons per minute and the
maximum capacity is 80 gallons per
minute.

Do not install a water shutoff valve in
the piping from the outlet of the pool
heater to the pool or spa. However, a
check valve that does not include a
shut-off feature may be installed for
convenience during servicing.

A check valve or Hartford Loop is
recommended between the unit and a
chlorinator. The chlorinator must be
downstream of the heat pump. Failure
to do so may void the warranty.

If you have an in-floor cleaning system,
please take note of any special
plumbing requirements to operate all
units effectively.

Figure 2 shows the recommended
installation layout.

CAUTION

that power to the unit is on. The
RED light indicates that the unit is
in heating mode.

• The RED light may become
illuminated prior to heater start up.
The RED light will become lit when
the thermostat knob is set at or
above the water temperature.

• The unit has a built in time delay

.
Every time the unit turns off there is
a five-minute time delay until the
unit may be restarted. The HEAT
light may turn on during this delay
cycle. Do not rotate the thermostat
knob during this time delay.
Rotating the knob during this cycle
may reset the time delay, causing
the unit to wait an additional five
minutes prior to startup.

Water Temperature Set
Point

• Temperature set point range is 45°F
to 107°F. Rotating the thermostat
knob clockwise will increase the
temperature set point, while
rotating counterclockwise will
decrease the temperature set point.

• A floating thermometer may be
placed in the pool or spa to monitor
water temperature.

• To initially calibrate the thermostat
to the desired set point, turn the

thermostat knob fully clockwise.
The unit will turn on and begin
heating after a possible five minute
time delay. Allow the unit to run
until pool or spa water reaches the
desired temperature. Slowly turn
thermostat knob counterclockwise
until the unit turns off. The unit will
now maintain this water
temperature, providing the
circulation pump is running.

Application
Guidelines

Maintenance

All heat pumps are designed for
outdoor use. However, some
maintenance is required to maintain
the full life of the heater and is
necessary to maintain your warranty.
Annual maintenance should be
scheduled to make sure blowing sand
or falling debris is removed from the
inside of the heater. Rinsing the coil
down monthly with low water pressure
will help keep the base of the unit clear
of debris. Do not use a high pressure
washer. This can cause damage to your
evaporator coils and will void your
warranty. It is recommended that a
licensed air conditioning specialist
perform the annual planned
maintenance on your heater.
