Safety Instructions

A 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.

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 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 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 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 Shutoff 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 less than 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 oflisted 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 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 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'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 open ing 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 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.

Safety Instructions (cont'd)

AWARNING

WATER HEATERS EQUIPPED FOR ONE VOLTAGE

ONLY: This water heater is equipped for one type

voltage only. Check the rating plate near the bot tom access panel for the correct voltage. DO NOT

use this water heater with any voltage other than

the one shown on the model rating plate. Failure to

use the correct voltage can cause problems which can result in DEATH, SERIOUS BODILY INJURY. OR PROPERTY DAMAGE. If you have any questions or doubts consult your electric company.

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 ieast 1% 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.

Instructions for Installation

Removing the Old Water Heater

^^Turn “OFF” electrical supply to the water heater.

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.

a. If you have copper piping to the water heater, the two

copper water pipes can be cut vrith 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 conapletely 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 discharge pipe. 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.

A WARNING

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.
