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,

AWARNING

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, d sh 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 I state law requiring a certain temperature water at I the hot water tap, then you must take special pre- I cautions. In addition to using the lowest possible I

temperature settingthat sattsfies 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- tacturers instructions for installation of the valves,

Before changing the factory setting on the thermo- stat, read the "Temperature Regulation" section in this manual,

AWARNING

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 cover or remove operating instructions, and safety related warning labels and materials affixed to the water heater,

AWARNING

At the time of manufacture this water heater was pro- vided with a combination temperature-pressures relief valve certified by a nationally recognized testing labo- ratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas

IShutoff Devices for Hot Water Supply Systems, and the latest edition of ANSI Z21.22 and the code require- ments of ASME. If replaced, the valve must meet the

requirements of local codes, but not lessthan a combi- nation 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 by a nationally recognized test- ing laboratory that maintains periodic inspection of production of listed equipment or materials.

The valve must be marked with a maximum set pres- sure not to exceed the marked hydrostatic working pressure of the water heater (150 Ibs./sq. in.) and a discharge capacity not less than the water heater

(Electric heaters - watts divided by 1000 x 3415 equal BTU/Hr. rate.)

inputYour localratejurisdias shownctional authority,on the modelwhile mandatingrating platethe. use of a temperature-pressure relief valve complying

with ANSi Z21.22 and ASME, may require a valve model different from the one furnished with the water heater.

Compliance with such local requirements must be sat- isfied by the installer or end user of the water heater with a locally 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'sdesignated 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 open- ing must not be blocked or reduced in size under any

circumstances. Excessivelength, 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 provid-

ed. To prevent bodily injury, hazard to life, or property damage, the relief valve must be allowed to discharge water in quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage.

The Discharge Pipe:

•Must notbe smaller in size than the outlet pipe size I

of the valve, or have any reducing couplings or I other restrictions.

:Must not be plugged or blocked.

Must be of material listed for hot water distribution.

of both the temperature-pressurerelief valve, and

• Must be installed so as to allow complete drain ge the discharge pipe.

• Must terminate at an adequate drain.

• Must not have any valve between the relief valve and tank.
