CAUTION –
These heaters are intended for use with permanently-installed pools and may be used with hot tubs and spas if so
marked. Do not use with storable pools. A permanently-installed pool is constructed in or on the ground or in a building such that it can-
not be readily disassembled for storage. A storable pool is constructed so that it is capable of being readily disassembled for storage and
reassembled to its original integrity.
WARNING
–
Risk of Hyperthermia.
To avoid hyperthermia the following
“Safety Rules for Hot Tubs” are recommended by the U.S.
Consumer Product Safety Commission.
1. Spa or hot tub 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. Prolonged immersion in hot water can induce hyperther-
mia.
2. Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness, which could lead to uncon-
sciousness and subsequently result in drowning.
3. Pregnant women beware! Soaking in water above 100°F [38°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 adhere 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 ther-mometer; spa or hot tub
thermostats may err in regulating water temperatures by as much as 4°F (2.2°C).
5. Persons taking medications, which induce drowsiness, such as tranquilizers, antihistamines or anti-coagulants, should not
use spas or hot tubs.
6. If the pool/spa is used for therapy, it should be done with the advice of a physician. Always stir pool/ spa water before entering
the pool/spa to mix in any hot surface layer of water that might exceed healthful temperature limits and cause injury. Do not
tamper with controls because scalding can result if safety controls are not in proper working order.
7. Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure problems should obtain
a physician’s advice before using spas or hot tubs.
8. Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above normal body tempera-
ture of 98.6°F [37°C]. The symptoms of Hyperthermia include: drowsiness, lethargy, dizziness, fainting, and an increase
in the internal temperature of the body.
The effects of Hyperthermia include:
Unawareness of impending danger.
Failure to perceive heat.
Failure to recognize the need to leave the spa.
Physical inability to exit the spa.
Fetal damage in pregnant women.
Unconsciousness resulting in danger of drowning.
DEFINITIONS:
Suction Outlet:
The Suction Outlet is a fitting, fitting assembly, cover/grate and related components that provide a means for water to exit the
pool and return into the pump circulating system. This fitting may also be referred to as the “Main Drain”
Bypass Valves:
A valve or series of valves that direct the pool water to flow or not flow through the heater.

Pressure measurement units:
Inches of Mercury (inHg)
is typically used with atmospheric pressure measurements.
Pounds per square inch (PSI)
is typically used with water “pressure”, “suction” or system measurements.
Inches of Water (inwc)
is typically used with gas or air pressure measurements
(1.0 inHg = .49 PSI = 13.5inwc)
