SAFETY INFORMATION

WARNING – Read, Understand, and Follow all Instructions in this manual and on the equipment. Failure to follow instructions can cause death, severe injury and/or serious property damage.

WARNING – Suction Entrapment Hazard. Suction in suction outlets and/or suction outlet covers which are,

damaged, broken, cracked, missing, or unsecured can cause death and/or severe injury due to the following entrapment hazards:

Hair Entrapment- Hair can become entangled in suction outlet cover.

Limb Entrapment- A limb inserted into an opening of a suction outlet sump 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- A negative pressure applied to a large portion of the body or limbs can result in an entrapment.

Evisceration/ Disembowelment - A negative pressure 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 knuckle to be caught in an opening of a suction outlet cover resulting in mechanical entrapment.

WARNING - To Reduce the risk of Entrapment Hazards:

o When outlets are small enough to be blocked by a person, a minimum of two functioning 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 measured from near point to near point.

o Dual suction fittings shall be placed in such locations and distances to avoid “dual blockage” by a user.

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

o The maximum system flow rate shall not exceed the flow rating of as listed on Table 1.

o Never use Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or not attached. o Replace damaged, broken, cracked, missing, or not securely attached suction outlet components immediately. o In addition two or more suction outlets per pump installed in accordance with latest ASME, APSP Standards and

CPSC guidelines, follow all National, State, and Local codes applicable.

o Installation of a vacuum release or vent system, which relieves entrapping suction, is recommended.

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 frequently and replaced at least every seven years or if found to be damaged, broken, cracked, missing, or not securely attached.

CAUTION – Components such as the filtration system, pumps and heater must be positioned so as to prevent their being used as means of access to the pool by young children. To reduce risk of injury, do not permit children to use or climb on this product. 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.

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

hazardous pressure during start up, normal operation, and after pump shut off. Stand clear of circulation system equipment during pump start up. Failure to follow safety and operation instructions could result in violent separation of the pump housing and cover, and/or filter housing and clamp due to pressure in the system, which could cause death, severe personal injury and/or property damage, 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 instructions could result in violent

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 – Risk of Electric Shock. All electrical wiring MUST be in conformance with applicable local

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. 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. 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 mm2) [No. 6 AWG (13.3 mm2) for Canada] solid copper bonding wire to the 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.

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.

INSTALLATION

This manual contains instructions for installation, operation, maintenance, troubleshooting, and parts lists for the proper operation of the swimming pool heaters. Manufacturer strongly recommends that the installer read the manual before installing the swimming pool heater. If after reviewing the manual any questions remain unanswered, contact the factory or local representative. Following heater installation, the installer should leave all manuals with the consumer for future reference.

NOTICE: The installation instructions are intended for the use of a qualified technician, specifically trained and experienced in the installation of this type of heating equipment. Some states or provinces require that installer be licensed. If this is the case in the state or province where heater is located, the contractor must be properly certified.

SPRINKLER HEADS: The heater is designed to handle the wettest weather conditions that are typical of rain and high humidity. Sprinkler heads force high-pressure water into the unit from the side at an odd angle. Make sure there are no sprinkler heads near the heater that will spray on or into the unit. Many sprinkler systems are connected to a well system, whose water is high in minerals, Sulphur, salt and other aggressive contaminates, that will leave a buildup on the unit and electronics causing corrosion and shortens life.

NOTICE: Damage from sprinkler interaction is not covered under the warranty agreement. Make sure that sprinklers are placed at a sufficient distance away so that normal wind will not carry the mist to the heat pump.

NOTICE: If located in an oceanfront area, the heat pump should be placed out of direct spray of sand and salt. This will clog, damage, and corrode the unit. You may also consider protecting the unit by creating a physical barrier outside of the minimum clearances between the unit and the prevailing beachfront wind. Damage caused by sand or salt spray is not covered by the warranty.

THE USE OF A POOL COVER IS RECOMMENDED. A pool cover reduces heat loss, conserves chemicals, lowers the load on filter systems and may provide a valuable safety feature

EQUIPMENT INSPECTION: On receipt of the heater, inspect the heater carton(s) for damage. If any carton(s) is damaged, note it when signing for it. Remove the heater from the carton(s) inspect it and advise the carrier of any damages at once.

NOTICE: Do not drop the heater from a pickup truck tailgate to the ground. This may damage the heater. NOTICE: The heat pump must not be tipped or transported on its side as evaporator “oil logging” may occur.

MATERIALS NEEDED FOR INSTALLATION

Installer is responsible for providing all external to unit electrical supplies. Extra hardware items may also be required for anchoring. Additional plumbing items needed:

For in ground installations: 2 inch PVC pipe Schedule 40 and 2 inch fittings and components as follows:

2 inch Isolation Valves		qty(3)
	2 inch Check Valve	qty(1)
	2 x 2 x 2 PVC Tee’s	qty(2)

NOTICE: Pipe fittings such as reducers, tees, and elbows cause pressure to drop as water flows through them. Plan the plumbing layout carefully, using as few fittings as possible to connect your heat pump. See pad plumbing layout in the WATER PIPING section for further direction.

LOCATING THE HEAT PUMP:

The installation location of the heat pump is very important for its efficient operation. The heat pump will perform more efficiently when placed in direct sunlight with ample air intake and the avoidance of air re-circulation. Locate the pool heater in an area where its condensation will not result in damage to the area adjacent to the heater or a nearby structure.

NOTICE: DO NOT install the heat pump in a fully enclosed space (i.e. garage, shed etc.). Such an installation will void its warranty

All criteria given in the following sections reflect minimum clearances. However, each installation must also be evaluated on prevailing local conditions such as proximity and height of walls and public access areas.

OUTDOOR INSTALLATION AND SERVICE CLEARANCES The heater must be installed outdoors such that the installation and service clearances shown in Table3 and Figure3 are maintained. Additional installation requirements are as listed;

1.Level surface for proper draining.

2.Suitable electrical supply line. See rating plate on the heat pump units for electrical specifications. A junction box is not needed at the heat pump; connections are made inside the heat pump electrical compartment. Minimum wire size to be selected per NEC based on unit MCA.

3.Electric disconnect switch that will interrupt all power to the unit. This switch MUST be within line of sight of the heat pump

4.Do not install in a location where growing shrubs may in time obstruct a heater’s air flow areas (sides or top).

5.Do not install the heater where water spray from ground level can contact the heater. The water could damage coil or reach the controls causing electrical damage.

6.Do not install under a deck.

7.Do not install within 24in of any outdoor HVAC equipment.
