WARNING
separation of pump and/or filter components. Strainer cover must be properly secured to pump housing with
strainer cover lock ring. Before servicing pool and spa circulation system, filters manual air relief valve must be in
open position. Do not operate pool and spa circulation system if a system component is not assembled properly,
damaged, or missing. Do not operate pool and spa circulation system unless filter manual air relief valve body is
in locked position in filter upper body. Never operate or test the circulation system at more than 50 PSI. Do
not purge the system with compressed air. Purging the system with compressed air can cause components to
explode, with risk of severe injury or death to anyone nearby. Use only a low pressure (below 5 PSI), high
volume blower when air purging the pump, filter, or piping.
WARNING
codes, regulations, and the National Electric Code (NEC). Hazardous voltage can shock, burn, and cause death
or serious property damage. To reduce the risk of electric shock, do NOT use an extension cord to connect unit
to electric supply. Provide a properly located electrical receptacle.
turn off power supply to the equipment. To reduce the risk of electric shock replace damaged wiring immediately.
Locate conduit to prevent abuse from lawn mowers, hedge trimmers and other equipment. Do NOT ground to a
gas supply line.

WARNING
Risk of Electric Shock. Failure to ground all electrical equipment can cause serious or fatal electrical shock
hazard. Electrical ground all electrical equipment before connecting to electrical power supply.
WARNING
– Risk of Electric Shock. Failure to bond all electrical equipment to pool structure will increase risk for
electrocution and could result in injury or death. To reduce the risk of electric shock, see installation instructions and consult a
professional electrician on how to bond all electrical equipment. Also, contact a licensed electrician for information on local
electrical codes for bonding requirements.
Notes to electrician: Use a solid copper conductor, size 8 or larger. Run a continuous wire from external bonding lug to
reinforcing rod or mesh. Connect a No. 8 AWG (8.4 mm
pressure wire connector provided on the electrical equipment and to all metal parts of swimming pool, spa, or hot tub, and metal
piping (except gas piping), and conduit within 5 ft. (1.5 m) of inside walls of swimming pool, spa, or hot tub.
IMPORTANT - Reference NEC codes for all wiring standards including, but not limited to, grounding, bonding and other general
wiring procedures.
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 cannot 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 hyperthermia.
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.
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 thermometer; 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 anticoagulants, 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
temperature 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.

F ail ure t o perc ei ve he at.

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.
