Instructions for Installation (cont’d)
*See illustration on page 8 for mixing valve usage.
The illustration shows the attachment of the water piping to
the water heater. The water heater is equipped with
3 ⁄
4
inch
water connections.
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 Maytag Customer Service at
1-800-788-8899 for an authorized servicer on how to con-
trol this situation.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adaptor to the cold water inlet connec-
tion. 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 permanently 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
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 sup-
ply or hardware stores. Follow manufacturers instruc-
tions 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.
