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
K 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 dam-
ме.
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.
