Water Chemistry
(Corrosive water voids all warranties)
or your health and the protection of your pool equipment, it is essential that your water be chemically
F
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!
• 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.

Warnings — Pay Attention to These Terms

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-407C refrigerant. Ensure that all
service work is done with gauges and equipment
suitable for R-407C.
3.
Pregnant Women Beware!
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.
6. Persons taking medications which induce drowsiness, such as tranquilizers, antihistamines, or
anticoagulants, should not use spas or hot tubs.

Introduction
WARNING: This pool/spa heat pump pool heater is
n electromechanical machine that incorporates a
a
pressurized refrigerant gas in a sealed system.
NLY trained and qualified service personnel are
O
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.
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.
Installation Considerations
ARNING: Do not install the unit within 3 ft of
W
fossil fuel burning heaters. Air intake along the
sides of this heat pump pool heater could disturb
the combustion process of the unit, and could
ause damage or personal injury.
c
• 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.
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.
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.

Fig. 1: Installation Clearances
• When installed in areas where freezing temperatures can be encountered, drain the water circuit
to prevent possible freeze-up damage. See the
Freeze Protection Section.
• 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.
• 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 upsizing 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 systems, heat-on-demand options and other external time
clock overrides. Refer to the external control system’s
instructions, and page 23 of this manual, for installation information.
