Instructions for Installation (cont’d)

*See illustration on page 9 for mixing valve usage.

If a water heater is installed in a closed water supply system;

such as one having a back-flow preventer, check valve, water

meter with a check valve, etc. in the cold water supply; means

shall be provided to control thermal expansion. Contact the local

utility or call a Maytag Service Specialist at 1-800-365-0024 for

an authorized servicer on how to control this situation.

NOTE: To protect against untimely corrosion of hot and cold

water fittings, it is strongly recommended that di-electric

unions or couplings be installed on this water heater when con-

nected to copper pipe.

NOTE: The secondary anode rod/hot outlet nipple and the

cold inlet nipple are packaged separately with the water

heater. The above parts must be installed in the appropriate

HOT and COLD water connection locations.

The illustration shows the attachment of the water piping to

the water heater. The water heater is equipped with

⁄4 inch

water connections.

NOTE: If using copper tubing, solder tubing to an adapter

before attaching the adaptor to the cold water inlet connection.

Do not solder the cold water supply line directly to the cold

water inlet. It will harm the dip tube and damage the tank.

1. Look at the top cover of the water heater. The water outlet

is marked hot. Connect the hot water pipe to the hot water

outlet of the water heater.

2. Look at the top cover of the water heater. The cold water

inlet is marked cold. Connect the cold water pipe to the

cold water inlet of the water heater.

NOTE: Your water heater is super insulated to minimize

heat loss from the tank. Further reduction in heat loss can

be accomplished by insulating the hot water lines from the

water heater.

*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 per-

manently injured by hot water than others. These include

the elderly, children, the infirm, or physically/mentally

handicapped. 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 precautions. In addi-

tion 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 manufac-

turers instructions for installation of the valves. Before

changing the factory setting on the thermostat, read the

“Temperature Regulation” section in this manual.

T&P Valve and Pipe Insulation

Remove insulation for T&P Valve

and pipe connections from carton.

Fit pipe insulation over the

incoming cold water line and the

hot water line. Make sure that the

insulation is against the top cover

of the heater.

Fit T&P Valve insulation over valve. Make sure that the insula-

tion does not interfere with the lever of the T&P valve.

Secure all insulation using tape.
