Safety Instructions
WARNING
Improper installation, adjustment, alteration, service or maintenance can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Refer to this manu- al for assistance consult your local utility or call Maytag Customer Service at 1-800-788-8899 for an authorized servicer for further information.
WARNING
HAZARD OF ELECTRICAL SHOCK! Before removing any access panels or servicing the water heater, make sure the electrical supply to the water heater is turned “OFF”. Failure to do this could result in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.
WARNING
HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/mentally handi- capped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special pre- cautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve, should be used at the hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores. Follow manu- facturers instructions for installation of the valves. Before changing the factory setting on the thermo- stat, read the “Temperature Regulation” section in this manual.
WARNING
INSULATING JACKETS: When installing an external water heater insulation jacket on an electric water heater:
•DO NOT cover the temperature-pressure relief valve.
•DO NOT put insulation over the access covers or any access areas.
•DO NOT remove operating instructions, and safety related warning labels and materials affixed to the water heater.
•DO obtain new warning and instruction labels from Maytag for placement on the jacket directly over the existing labels.
WARNING
Do not use this appliance if any part of it has been under water. An electrical short or malfunction could occur. The water heater should be replaced.
WARNING
At the time of manufacture this water heater was pro- vided with a combination temperature-pressures relief valve certified by a nationally recognized testing labora- tory that maintains periodic inspection of production of listed equipment or materials, as meeting the require- ments for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, and the current edition of ANSI Z21.22 • CSA 4.4 and the code require- ments of ASME. If replaced, the valve must meet the requirements of local codes, but not less than a combina- tion temperature and pressure relief valve certified as meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 • CSA 4.4 by a nationally recog- nized testing laboratory that maintains periodic inspec- tion of production of listed equipment or materials.
The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 lbs./sq. in.) and a discharge capacity not less than the water heater input rate as shown on the model rating plate. (Electric heaters - watts divided by 1000 x 3412 equal BTU/Hr. rate.)
Your local jurisdictional authority, while mandating the use of a temperature-pressure relief valve complying with ANSI Z21.22 • CSA 4.4 and ASME, may require a valve model different from the one furnished with the water heater.
Compliance with such local requirements must be satis- fied by the installer or end user of the water heater with
alocally prescribed temperature-pressure relief valve installed in the designated opening in the water heater in place of the factory furnished valve.
For safe operation of the water heater, the relief valve must not be removed from it’s designated opening or plugged.
The temperature-pressure relief valve must be installed directly into the fitting of the water heater designated for the relief valve. Position the valve downward and provide tubing so that any discharge will exit only within 6 inches above, or at any distance below the structural floor. Be certain that no contact is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet, or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve.
No valve or other obstruction is to be placed between
the relief valve and the tank. Do not connect tubing directly to discharge drain unless a 6″ air gap is provided.
To prevent bodily injury, hazard to life, or property dam- age, the relief valve must be allowed to discharge water in quantities should circumstances demand. If the dis- charge pipe is not connected to a drain or other suitable means, the water flow may cause property damage.
The Discharge Pipe:
•Must not be smaller in size than the outlet pipe size of the valve, or have any reducing couplings or other restrictions.
•Must not be plugged or blocked.
•Must be of material listed for hot water distribution.
•Must be installed so as to allow complete drainage of both the temperature-pressure relief valve, and the discharge pipe.
•Must terminate at an adequate drain.
•Must not have any valve between the relief valve and tank.
