This appliance must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This appliance is equipped with a cord having an equipment grounding conductor and a grounding plug.
CARE AND USE
The plug must be plugged into a three pin receptacle that is properly installed and grounded in accordance with all local codes and ordinances. Have a licensed electrician check for ground continuity of the electrical supply system to insure proper grounding of the water heater.
Property Damage: Hydrogen gas can be produced in a hot water system served by this 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 connected to the hot water system be opened for several minutes before using any electrical appliance. If hydrogen is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. There should be no smoking or open flame near the faucet at the time it is open.
Personal Injury: “Insulation Blankets” are available for external use on electric water heaters. But are not recommended by InSinkErator.
If you choose to ignore our recommendations and install an insulated blanket on this heater you must adhere to the following precautions in order to prevent serious injury or death to yourself or others: (1)The junction box, external wiring, thermostats or heating elements on electric water heaters must not be covered; (2)The
Property Damage: To reduce the risk of excessive pressures and temperatures in this water heater 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.
Temperature and Pressure Relief Valve. This valve must be marked with a maximum set pressure not to exceed the marked maximum working pressure of the water heater. Install the valve into an opening provided and marked for this purpose in the water heater, and orient it or provide tubing so that any discharge from the valve will exit only within 6 inches above or at any distance below the structural floor and cannot contact any live electrical part. This discharge opening must not be blocked or reduced in size under any circumstances.
Check the metal tag on the relief valve and compare it to the heater’s rating plate. Pressure rating of relief valve must not exceed the working pressure shown on the rating plate of the heater and the A.G.A. hourly Btu rated temperature steam discharge capacity of the relief valve shall not be less than the input rating of the heater. No valve is to be placed between the relief valve and tank. Do not plug the relief valve.
The drain line connected to the valve must not contain a reducing coupling or other restriction and should terminate near a suitable drain to prevent water damage during valve operation. Discharge line shall be installed to allow complete drainage of both the valve and line. Do not thread, plug or cap the end of the drain line.
ADJUSTING THE THERMOSTAT
Heating element has a thermostat which is factory set at 120˚F (49˚F) unless specified differently by
state requirements.
■Turn off the heater electrical supply.
■Unplug power cord.
■Remove front panel.
■Move temperature indicator on thermostat to desired temperatures.
■Replace panel, plug in power cord and turn on heater electrical supply.
A
Personal Injury: The consumer
product safety commission recommends temperatures of
130˚F or lower setting the temperature higher will increase the risk of scald injury.
Property Damage: Because the
high limit operates only when abnormally high water
temperatures are present, it is important that a service agent be contacted to determine the reason for the high limit operation before resetting the high limit.
SEASONAL STORAGE/DRAINAGE
Anytime the water heater is not used for extended periods of time, unplug and drain unit. If it is below freezing you will need to unplug the unit and drain it.
■Disconnect power from unit.
■Turn on “hot” faucet until water runs cool.
■Shut off cold water supply to heater.
■Leave hot faucet open to bleed off water pressure.
■Remove drain screw from
■Drain water from tank into suitable container.
■Leave the drain screw open during shut down.
■Close hot water faucet.
■To place back in working order, follow filling instructions.
MAINTENANCE
Periodically drain the tank to help prevent sediment buildup. See draining instructions.
The temperature and pressure relief valve should be checked periodically to ensure it operates properly. Lift the level at the top of the valve to see if the valve opens and closes properly.
Personal Injury: The water
passing out of the valve during this check may be extremely hot.
Collect discharge in appropriate containers.
WHAT TO DO IF SOMETHING GOES WRONG
Check the things you can do yourself:
■Be sure water heater is plugged firmly into appropriate receptacle or is properly electrically connected in some other manner.
■Be sure fuses and circuit breakers are in good order.
■Reread instruction booklet to assure that you are using correct operation procedure.
■Many unnecessary service calls result in the service agent doing what the owner can do for himself.
