IMPORTANT SAFETY INSTRUCTIONS

Before installing or servicing this electrical equipment, turn power supply OFF.

KEEP SAFETY LABELS IN GOOD CONDITION AND REPLACE IF MISSING OR DAMAGED.

WARNING – To reduce risk of injury, do not permit children to use or climb on the heater, pumps or

ﬁlters. Closely supervise children at all times. Components such as the ﬁltration system, pumps, and

heaters must be positioned to prevent children from using them as a means of access to the pool.

CAUTION – This heater is intended for use on permanently installed swimming pools and may also

be used with spas. 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. Astorable pool is

constructed so that it is capable of being readily disassembled for storage and reassembled to its original

integrity.

Though this product is designed for outdoor use, it is strongly recommended to protect the electrical

components from the weather. Select a well drained area, one that will not ﬂood when it rains. It requires free

circulation of air for cooling. Do not install in a damp or non-ventilated location.

WARNING – It is required that licensed electricians do all electrical wiring. Risk of

Electric Shock. Hazardous voltage can shock, burn, 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 outlet. All electrical wiring MUST be

in conformance with applicable local and national codes and regulations. Before work-

ing on this unit, turn off power supply to the heater.

WARNING – To reduce the risk of electric shock replace damaged wiring immediately. Locate conduit

to prevent abuse from lawn mowers, hedge trimmers and other equipment.

WARNING – Failure to bond to pool structure will increase risk for electrocution and could result in

injury or death. To reduce the risk of electric shock, the electrician must comply with installation in-

structions and must bond the heater accordingly. In addition, the licensed electrician must also conform

to local electrical codes for bonding requirements.

SAFETY INFORMATION

NOTES TO THE ELECTRICIAN:

Use a solid copper conductor, size 8 or larger. Run a continuous wire from external bonding lug to rein-

forcing rod or mesh. Connect a No. 8 AWG solid copper bonding wire to the grounding lug provided on the

heater and to all metal parts of swimming pool or spa, and to all electrical equipment, metal piping (except

gas piping), and conduit within 5 ft. (1.5 m) of inside walls of swimming pool or spa.

IMPORTANT -Reference NEC codes for all wiring standards including, but not limited to, grounding,

bonding and other general wiring procedures.

WARNING – Suction Entrapment Hazard.

Suction in suction outlets and/or suction outlet covers which are damaged, broken,

cracked, missing, or unsecured can cause severe injury and/or death due to the fol-

lowing entrapment hazards:

Hair Entrapment- Hair can become entangled in suction outlets.

Limb Entrapment- Alimb inserted into an opening of a suction outlet or suction outlet

cover that is damaged, broken, cracked, missing, or not securely attached can result in a

mechanical bind or swelling of the limb.

Body Suction Entrapment- Adifferential pressure applied to a large portion of the body or limbs can

result in an entrapment.

Evisceration/ Disembowelment - Avacuum applied directly to the intestines through an unprotected

suction outlet sump or suction outlet cover which is damaged, broken, cracked, missing, or unsecured

can result in evisceration (disembowelment).

Mechanical Entrapment- There is potential for jewelry, swimsuit, hair decorations, ﬁnger, toe or knuck-

le to be caught in an opening of a suction outlet or suction outlet cover resulting in mechanical entrap-

ment.

WARNING - To reduce the risk of entrapment hazards:

• When suction outlets are less than a 18” x 23” equivalent, a minimum of two function-

ing suction outlets per pump must be installed. Suction outlets in the same plane (i.e.

ﬂoor or wall), must be installed a minimum of three feet (3’) [1 meter] apart, as mea-

sured from near point to near point.

• Dual suction outlets shall be placed in such locations and distances to avoid “dual

blockage” by a user.

• Dual suction ﬁttings shall not be located on seating areas or on the backrest for such

seating areas.

• The maximum system ﬂow rate shall not exceed the ﬂow rating of any listed (per current revision of

ASME/ANSI A112.19.8) suction outlet cover installed.

• Never use the Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or

not securely attached.

• Replace damaged, broken, cracked, missing, or not securely attached suction outlet components im-

mediately.

• Install two or more suction outlets per pump in accordance with latest APSP (formally NSPI) Stan-

dards and CPSC guidelines. Follow all applicable National, State, and Local codes.

WARNING – Failure to remove pressure test plugs and/or plugs used in winterization of the pool/spa

from the suction outlets can result in an increase potential for suction entrapment as described above.

WARNING – Failure to keep suction outlet components clear of debris, such as leaves, dirt, hair, paper

and other material can result in an increase potential for suction entrapment as described above.

WARNING – Suction outlet components have a ﬁnite life, the cover/grate should be inspected fre-

quently and replaced at least every ten years or if found to be damaged, broken, cracked, missing, or not

securely attached.

WARNING – All suction and discharge valves MUST be OPEN when starting the circulation system.

Failure to do so could result in severe personal injury and/or property damage. All drains and suction

outlets MUST have properly installed covers, securely attached using the screws supplied with the cov-

ers. If screws are lost, order replacement parts from your supplier.

WARNING – Hazardous Pressure. Pool and spa water circulation systems operate

under hazardous pressure during start up, normal operation, and after pump shut off.

Stand clear of circulation system equipment during start up. Failure to follow safety

and operation instructions could result in violent separation of the pump housing

and cover due to pressure in the system, which could cause property damage, severe

personal injury, or death. Before servicing pool and spa water circulation system, all

system and pump controls must be in off position and ﬁlter manual air relief valve

must be in open position. Before starting system pump, all system valves must be set

in a position to allow system water to return back to the pool. Do not change ﬁlter

control valve position while system pump is running. Before starting system pump,

fully open ﬁlter manual air relief valve. Do not close ﬁlter manual air relief valve

until a steady stream of water (not air or air and water) is discharged.

WARNING – Separation Hazard. Failure to follow safety and operation instruc-

tions could result in violent separation of pump components. Strainer cover must be

properly secured to pump housing with strainer cover lock ring. Before servicing

pool and spa circulation system, 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 air relief valve body is in locked position in ﬁlter upper body.

WARNING – Never operate or test the circulation system at more than 40 PSI.

WARNING – Fire and burn hazard. Motors operate at high temperatures and if they are not properly

isolated from any ﬂammable structures or foreign debris they can cause ﬁres, which may cause severe

personal injury or death. It is also necessary to allow the motor to cool for at least 20 minutes prior to

maintenance to minimize the risk of burns.

WARNING – Failure to install according to deﬁned instructions may result in severe personal injury or

death.

WARNING – The following “Safety Rules for Hot Tubs” recommended by the U.S. Consumer

Product Safety Commission should be observed when using the spa.

1. Spa or hot tub water temperatures should never exceed 104°F [40°C]. Atemperature of 100°F

[38°C] is considered safe for a healthy adult. Special caution is suggested for young children. Pro-

longed 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). Preg-

nant 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 physicians 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: drowsi-

ness, lethargy, dizziness, fainting, and an increase in the internal temperature of the body.

The effects of Hyperthermia include:

1. Unawareness of impending danger.

2. Failure to perceive heat.

3. Failure to recognize the need to leave the spa.

4. Physical inability to exit the spa.

5. Fetal damage in pregnant women.

6. Unconsciousness resulting in danger of drowning.

SECTION I. GENERAL INFORMATION

8SECTION II. CONSUMER OPERATION & MAINTENANCE

The heat exchanger in your Trane pool heater is made from the highest quality of copper and nickel (Cu-

pronickel) materials. The premium materials and the exacting processes used in the manufacture of the heat

exchanger is state of the art in pool heater design and manufacture. Yet, it remains vital that the heat exchang-

er be protected from damaging or corrosive chemicals, insufﬁcient water ﬂow or improperly balanced water

chemistry. Heat exchanger damage or failure resulting from improper ﬂow, improperly balanced pool water

or the improper addition of sanitizers into the water is NOT covered under the terms of your warranty.

The following factors are critical to heat exchanger protection. Follow these guidelines to help prevent

pre-mature damage or failure to your heater and heat exchanger.

1. WATER FLOW THROUGH HEATER

Water must be ﬂowing through the heater at the minimum rated ﬂow rate during operation. Check that

the pump is operating and the system is ﬁlled with water and purged of all air prior to starting the heater. The

minimum rated ﬂow rates are listed in Table 14 of the installation manual on page 25. Some installations may

require an adjustment to the water pressure switch for proper low-ﬂow protection. Test your system and if

necessary, adjust the water pressure switch as described in the installation manual on page 36.

2. POOL/SPAWATER CHEMISTRY

The chemistry balance and mineral content of swimming pool water changes daily due to the addition of

pool and sanitizing chemicals, bather loads, rain, runoff and the amount of sun - to name a few. Improper chem-

istry balance and mineral content can cause scaling and deposits to form on pool walls, in the ﬁltration system,

in the heat exchanger tubes and additionally can promote corrosive action to all metals in the water path. Chang-

ing spa water regularly and maintaining the correct chemical balance in your pool/spa will keep the pool/spa

safe and sanitary, and will help protect the heat exchanger. Use a 4-way pool/spa water test kit to check your

water frequently (at least weekly). Use the following guidelines to help protect your heater’s heat exchanger:

3. SKIMMER CHLORINATION

Placing chlorine or bromine tablets directly into the skimmer may result in high chemical concentrations

ﬂowing through the heater. DO NOT place chlorine or bromine tablets in the skimmer.

WARNING: Failure to Maintain Proper Water Chemistry May Cause

Premature Heat Exchanger Damage or Failure

MAINTAINING PROPER WATER CHEMISTRY

WARNING: If you smell gas in the appliance area or near the ﬂoor (PROPANE IS

HEAVIER THAN AIR AND HENCE SETTLES ON THE FLOOR), stop and follow

the instructions on the front cover of this manual. Since propane can accumulate in con-

ﬁned areas, extra care should be taken when lighting propane heaters.

ATTENTION: Do not use the heater below 40°F (4°C) temperature without adequate temperature protection.

WARNING: Do not ingest alcohol or drugs during use or prior to using pool, spa, or hot tub. Ingestion of such

intoxicants can cause drowsiness, which can lead to unconsciousness, and subsequently result in drowning.

4. CHLORINATOR INSTALLATION

Chlorinators must be installed downstream of the heater, and a check valve must be installed between the

heater and chlorinator to prevent high chemical concentrations from back ﬂowing into the heater. Make sure your

piping arrangement meets the chlorinator installation requirements shown in the installation manual on page 26.

5. BYPASS

Until water chemistry is properly balanced, and if your piping has a bypass valve installed for the heater,

open the bypass so that corrosive and potentially damaging water will not ﬂow through the heater and there-

fore the heat exchanger. Close the bypass valve once the water is properly balanced. Failure to close the

bypass valve when attempting to operate the heater will result in extensive damage to the heat exchanger.

Ensure water ﬂow through the heater is restored before operating the heater. A bypass feature is also advanta-

geous for service needs and for the ability to remove the heater from the water path when not heating. Refer

to page 25 in the installation manual for further information.
