Safety Instructions

AWARNING

Improper installation, adjustment, alteration, service

or maintenance can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Refer to this manu al for assistance consuit 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.

AWARNING

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

eople are more likely to be permanently injured by ot 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 sucn 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.

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

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.

AWARNING

At the time of manufacture this water heater was pro vided with a combination temperature-pressures relief valve certified by a nationally recognizeci 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 latest

edition of ANSI Z21.22 and the code requirements of ASME. If replaced, the valve must meet the require

ments of local codes, but not less than a combination

temperature and pressure relief valve certified as meet

ing the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 by a nationally recognized testing laboratory that maintains periodic inspection of production of list ed 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 Ibs./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 3415 equal BTU/Hr. rate.) Your local jurisdictional authority, while mandating the

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 satis fied 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'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 with in 6 inches above, or at any distance below the struc tural 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 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 suit able means, the water flow may cause property damме. 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.

Installation Instructions

Removing the Old Water Heater

^^Turn “OFF" electrical supply to the water heater. a.

Turn “OFF” the water supply to the

water heater at the water shutofif valve or water meter.

Attach a hose to the water heater drain valve and put the other end in a floor drain or outdoors. Open the water heater drain valve. Open a nearby hot water faucet which will relieve pressure in the water heater and speed draining.

If you have copper piping to the water heater, the two copper water pipes can be cut with a hacksaw approxi

mately four inches away from where they connect to the water heater. This will avoid cutting off the pipes

too short. Additional cuts can be made later if neces sary. Disconnect the temperature-pressure relief valve drain line. When the water heater is drained, discon

nect the hose from the drain valve. Close the drain

valve. The water heater is now completely disconnect

ed and ready to be removed.

b. If you have galvanized pipe to the water

heater, loosen the two galvanized pipes with a pipe wrench at the union in each line. Also disconnect the piping remain ing to the water heater. These pieces should be saved since they may be needed when reconnecting the new water heater. Disconnect the temperature-pressure relief valve drain line. When the water heater is drained, disconnect the hose from the drain valve. Close the drain valve. The water heater is now completely disconnected and ready to be removed.

AWARNING

The water passing out of the drain valve may be extremely hot. To avoid being scalded, make sure all connections are tight and that the water flow is directed away from any person.

Check again to make sure the electrical supply is turned “OFF” to the water heater. Then disconnect the electri cal supply connection from the water heater junction box.

A CAUTION

Mineral buildup or sediment may have accumulated in the old water heater. This causes the water heater to be much heavier than normal and this residue, if spilled out, could cause staining.

Instructions for Installation (cont'd)

Locating The New Water Heater

You should carefully choose an indoor location for the new water heater, because the placement is a very important con

sideration for the safety of the occupants in the building and for the most economical use of the appliance. This water heater is not intended for outdoor installation.

Whether replacing an old water heater or putting the water

heater in a new location, the following critical points must be observed.

1. The location selected should be indoors as close to and as

centralized with the water piping system as possible. This water heater, as well as all water heaters, will eventually leak. Do not install without adequate drainage provisions where water flow will cause damage.

A CAUTION

WATER HEATERS EVENTUALLY LEAK: Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow of water will not cause damage to the structure. For this reason, it is not advisable to install the water heater in an attic or upper floor. When such locations cannot be avoided, a suitable drain pan should be installed under the water heater. Drain pans are available at your local hardware store. Such a drain pan must have a minimum diam eter of at least IV« inches greater than the water heater diameter and must be piped to an adequate drain. Under no circumstances is the manufacturer or

Maytag to be held liable for any water damage in

connection with this water heater.

A CAUTION

INSTALLATION IN RESIDENTIAL GARAGES: The water

heater must be located and/or protected so it is not

subject to physical damage by a moving vehicle.

2. The location selection must provide adequate clearances for

servicing and proper operation of the water heater.
