1. WARNINGS
Pay Attention to these Terms
ADANGER
AWARNING
ACAUTION
CAUTION
NOTE
CAUTION: Improper chemical content in a swimming
pool or spa can damage the heater. DO NOT add pool
chemicals to the skimmer. This will damage the heater.
Such damage will not be covered under warranty.
ALWAYS follow the product manufacturer’s directions
when adding any chemicals to your pool.
CAUTION: Elevated water temperature can be
hazardous. The U.S. Consumer Product Safety
Commission has these guidelines:
• 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.
• 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.
• 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.
• 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).
• 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.
• Persons taking medications which induce
drowsiness, such as tranquilizers, antihistamines,
or anticoagulants, should not use spas or hot
tubs.
AWARNING: These heaters are charged with R-410A
refrigerant. Ensure that all service work is done with
gauges and equipment suitable for R-410A.

NOTEDamaged caused by water chemistry outside
these guidelines will not be covered under warranty.

2. INTRODUCTION
AWARNING: This pool/spa heater is an
electromechanical machine that incorporates a
pressurized refrigerant gas in a sealed system. ONLY
trained and qualied 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.
3. INSTALLATION
CONSIDERATIONS
AWARNING: Do not install the unit within 3 ft (91 cm)
of fossil-fuel-burning heaters. Air intake along the sides
of this 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 (91 cm by 91 cm).
• You must install the 4 black rubber sound isolation
pads (each 2 inches square [5.1² cm]) 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.
AWARNING: This unit is designed for outdoor
installation ONLY; DO NOT install it in an enclosed area
such as a shed or garage.

(MODELS 6350HC AND

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.
12
NOTE: Heating is more ecient during warmer daylight
hours and cooling is more ecient during cooler night
time hours.
13. SYSTEM START-UP
page
14. 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 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: If the pool pump and 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 heater capacity and eciency 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.

Air Coil Cleaning

CAUTION: To clean the ns, spray gently with a garden
hose. DO NOT pressure wash. Doing so will bend the
ns, causing damage which will not be covered under
warranty.
Cabinet Care (optional)
AWARNING: Shut OFF electricity to the unit before
cleaning.
Unplug Condensation Drain Holes
18. TROUBLESHOOTING
NOTE: If the compressor fails to start when energized,
and there are no faults detected in the wiring, contact the
factory for the appropriate “Hard Start Kit.”
A. Unit Is Running, But Not Heating
Remember
that the heater only operates while the pool pump is
running.
NOTE: If the pool pump and 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 eciency 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.
B. Unit Is Not Running
NOTE: The heater will not run when the Remote position
is selected on the Pool/Spa selector switch and there is
no remote control system attached.
