circulation system, filters manual air relief valve must be in open position. Do not operate pool and spa circulation system if a system compo-
nent 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 com-
pressed 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
Risk of Electric Shock.
-
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. Before working on any
electrical equipment, 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.
-
Electrical ground all electrical equipment before connecting to electrical power supply.

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 mm2) [No. 6 AWG (13.3 mm2) for Canada] solid copper bonding wire to the pressure wire connector pro-
vided 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.
-
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.
• 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.

All electrical wiring MUST be in conformance with applicable local codes, regulations, and the
Failure to ground all electrical equipment can cause serious or fatal electrical shock hazard.
Failure to bond all electrical equipment to pool structure will increase risk for electrocution and
To avoid hyperthermia the following "Safety Rules for Hot Tubs" are recommended by the U.S.
