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 Maytag Customer Service at 1-800-788-8899 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
connected 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
3
⁄
4
inch water
connections.
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 out-
let 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 accom-
plished by insulating the hot water lines from the water heater.

WARNING
HOTTER WATER CAN SCALD: Water heaters are intend-
ed to produce hot water. Water heated to a tempera-
ture 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 physi-
cally/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 tempera-
ture water at the hot water tap, then you must take
special precautions. In addition to using the lowest pos-
sible 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 manufacturers
instructions for installation of the valves. Before chang-
ing the factory setting on the thermostat, read the
“Temperature Regulation” section in this manual.
T&P Valve and Pipe Insulation
(on Selected Models)
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.
