  • Page 3: General Information

    GENERAL INFORMATION This water heater must be installed in accordance with local codes. In the absence of local codes, install this water heater in accordance with national or regional requirements. The best efficiency and longest product life is obtained only when the water heater is installed, adjusted and operated in accordance with these Installation and Operating Instructions.

  • Page 4: Installation

    General Information continued- A sacrificial anode(s) is used to extend tank life. Removal of any anode, for any reason, will shorten the products useful life. In areas where water is unusually active, an odor may occur at the hot water faucet due to a reaction between the sacrificial anode and impurities in the water.
  • Page 5 Locating The Water Heater continued- Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical vapors. Examples of some typical compounds that are potentially corrosive are: spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium or sodium chloride, waxes and process chemicals.

  • Page 6: Water Connections

    Water Connections NOTE: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY VALVE. After shutting the main water supply valve, open a faucet to relieve the water line pressure to prevent any water from leaking out of the pipes while making the water connections to the water heater.
  • Page 7 Water Connections continued- WARNING For protection against excessive temperatures and pressure, install temperature and pressure protective equipment required by local codes, but not less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the Requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22, and the Standard...
  • Page 8 Water Connections continued- WARNING Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system.
  • Page 9 Water Connections continued- Water temperature over 125°F (52°C) can cause severe burns instantly or death from scalds. Children, disabled and elderly are at highest risk of being scalded. Review this instruction manual before setting temperature at water heater. Feel water before bathing or showering.
  • Page 10 Water Connections continued- The hot and cold water connections are identified on the top of the water heater. Connect the hot and cold water lines to the installed nipples using unions. Install a listed temperature-pressure relief valve in the opening on the top of the water heater.

  • Page 11: Electrical Connections

    Electrical Connections Before any electrical connections are made, be sure the water heater is full of water and the manual shut-off valve located in the cold water supply line is open. If the heating elements are not completely immersed in water at all times, they will be damaged (burned-out) if energized for even a short period of time.

  • Page 12: Amperage Chart

    Electrical Connections continued- Heating Elements To replace heating elements, disconnect power to the water heater, drain tank and replace element. To remove a heating element, use a 1 1/2” screw type element wrench that is usually available at places where plumbing supplies can be obtained.

  • Page 13: General Operation

    Failure of the element(s) due to dry-firing is not covered by warranty. When the switch is closed, the operation of this electric water heater is automatic. The water heater thermostat(s) are preset to the “HOT” setting to provide a water temperature of approximately 140°F (60°C) or below in order...

  • Page 14: Thermostat Adjustment

    Thermostat Adjustment CAUTION Before adjusting thermostat(s), turn off power supply to the water heater. The temperature of the water can be changed by adjusting the thermostat(s). Before any work is done on the water heater, disconnect all power to the water heater by opening the switch at the main electrical circuit breaker or fuse box.

  • Page 15: Maintenance

    MAINTENANCE IMPORTANT The water heater should be inspected at a minimum of annually by a qualified service technician for damaged components. DO NOT operate this water heater if any part is found damaged. Shut off the electric power whenever the water supply to the water heater is off.
  • Page 16 Maintenance continued- 3. At least once a year, check the combination temperature and pressure relief valve to insure that the valve has not become encrusted with lime. Lift the lever at the top of the temperature-pressure relief valve several times until the valve seats properly without leaking and operates freely. WARNING When lifting lever of temperature-pressure relief valve, hot water will be released under pressure.
  • Page 17 Maintenance continued- Contact your local plumbing supplier or plumbing professional for replacement parts or contact the company at the address displayed on the rating plate of the water heater. For faster and better service, please provide the part name, model, and serial number(s) of the water heater(s) when ordering parts.
