Checking equipment –

Upon receiving equipment, check for signs of shipping damage. Pay particular attention to parts accompanying the pool heater which may show signs of being hit or otherwise being mishandled. Verify total number of pieces shown on the packing slip with those actually received. In case there is damage or a shortage, immediately notify the carrier.

Warranty –

Factory warranty (shipped with unit) does not apply to units improperly installed or improperly operated.

Experience has shown that improper installation or system design, rather than faulty equipment, is the cause of most operating problems.

1.Improper maintenance of pool water chemistry resulting in high water hardness and high alkalinity that results in a lime scale build up in the copper tube is not the fault of the equipment and is not covered under the manufacturer’s warranty (see Facts About Water Chemistry in the EnergyRite Service Manual).

2.Excessive pitting and erosion on the inside of the copper tube may be caused by too much water velocity through the tubes and is not covered by the manufacturer’s warranty (see Water Connections in the

EnergyRite Installation and Operation Manual).

Owner warning –

The information contained in this manual is intended for use by qualified professional installers, service technicians, or gas suppliers. Consult your local expert for proper installation or service procedures.

NOTICE

Consult and follow all local Building and

Fire Regulations and other Safety Codes that

 

 

 

apply to this installation. Consult a local gas

 

utility company to authorize and inspect all

 

gas and flue connections.

Your conventionally vented gas pool heater must have a supply of fresh air circulating around it during burner operation for proper gas combustion and proper venting.

WARNING Should overheating occur or the gas supply fail to shut off, do not turn off or disconnect

the electrical supply to the pump. Instead, turn off the manual gas control valve to the appliance at a location external to the appliance.

Prevention of freezing –

Heat exchangers and headers damaged by freezing are not covered by warranty.

Spa and hot tub safety –

Codes –

The following safety rules must be observed while operating spa or hot tub.

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.

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 102°F (39°C) can cause fetal damage during the first three months of pregnancy (resulting in birth of braindamaged or a deformed child). Pregnant women should observe 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°C).

5.Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure problems should obtain their physician’s advice before using spas or hot tubs.

6.Persons taking medications which induce drowsiness, such as tranquilizers, antihistamine or anticoagulants, should not use spas or hot tubs.
