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.
4. Check again to make sure the electrical supply is turned
“OFF” to the water heater. Then unplug the water heater
(cord set) or disconnect the electrical supply connection
from the water heater junction box.
1. Turn “OFF” electrical supply to the water heater.
FIGURE 2.
2. Turn “OFF” the water supply to the water heater at the water
shut-off valve or water meter.
FIGURE 3.
3. 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.
FIGURE 4.
FIGURE 5.
5. a. If you have copper piping to the water heater, the two
copper water pipes can be cut with a hacksaw
approximately 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 necessary.
Disconnect the temperature-pressure relief valve
drain line. 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.
FIGURE 6.
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
remaining 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 drain line. 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.

• Sensors mounted in the drain pan that turn off the water supply
to the entire home when water is detected in the drain pan.
• Water supply shut-off devices that activate based on the water
pressure differential between the cold water and hot water
pipes connected to the water heater.
INSULA TION BLANKETS
FIGURE 7.
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.
Locating the New Water Heater
Insulation blankets are available to the general public for
external use on electric water heaters but are not necessary
with this product. The purpose of an insulation blanket is to
reduce the standby heat loss encountered with storage tank
heaters. Your water heater meets or exceeds the National
Appliance Energy Conversation Act standards with respect to
insulation and standby loss requirements, making an insulation
blanket unnecessary.
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions below. Failure to follow
these instructions can result in fire, serious personal injury, or
death.
•
Do not cover the temperature and pressure relief (T & P)
valve with an insulation blanket.
• Do not cover the instruction manual. Keep it on the side of
the water heater or nearby for future reference.
• Do obtain new warning and instruction labels for placement
on the blanket directly over the existing labels.
T ypical Installation
Check all connections for leaks. Consult the local utility
company to examine installation for propriety and safety .
You should carefully choose an indoor location for the new
water heater, because the placement is a very important
consideration for the safety of the occupants in the building
and for the most economical use of the appliance. This water
heater is not intended for outdoor installation.
Whether replacing an old water heater or putting the water
heater in a new location, the following critical points must be
observed.
• The location selected should be indoors as close to and as
centralized with the water piping system as possible. This
water heater, as well as all water heaters, will eventually
leak. Do not install without adequate drainage provisions
so water flow will not cause damage.
Water heater life depends upon water quality, water pressure
and the environment in which the water heater is installed.
Water heaters are sometimes installed in locations where
leakage may result in property damage, even with the use of a
drain pan piped to a drain. However, unanticipated damage
can be reduced or prevented by a leak detector or water shutoff device used in conjunction with a piped drain pan. These
devices are available from some plumbing supply wholesalers
and retailers, and detect and react to leakage in various ways:
• Sensors mounted in the drain pan that trigger an alarm or
turn off the incoming water to the water heater when leakage
is detected.
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, shall be used at the hot water taps used by these people
or at the water heater. Mixing valves are available at plumbing
8
supply or hardware stores. Follow manufacturers instructions
for installation of the valves. Before changing the factory setting
on the thermostat, read the “Temperature Regulation” section
in this manual.
INST ALLA TION IN RESIDENTIAL GARAGES: The water heater
must be located and/or protected so it is not subject to physical
damage by a moving vehicle.
• The location selection must provide adequate clearances
for servicing and proper operation of the water heater.
The Convertible Lower Element
The Upper Element, is a conventional 3800 watt element which
only operates at its rated wattage on 240 volts. (See rating
plate on the water heater).
The Lower Element of the water heater can be converted from
operation at 3800 watts to 5500 watts on a 240 volt system.
Read and follow water heater warnings and instructions. If
after reading these instructions in this manual, you do not
understand any portion, call Maytag Customer Service at
1-800-788-8899 for an authorized sevicer.
FIGURE 8
WA TER HEA TERS EVENTUALL Y 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 length and width of at least 1 3/4 inches greater than
the water heater dimensions and must be piped to an
adequate drain.
Before making the conversion to 5500 watts, check the (1)
power supply . . . must be 240 volts, (2) wiring . . . 10 gauge
AWG @ Type TW, 60°C or equivalent, and (3) Circuit breakers
or fusing . . .capable of 30 amp loading. Also, the installation
must conform with this manual, local codes and electric utility
rules. Failure to comply can result in DEA TH, SERIOUS BODILY
INJURY , OR PROPER TY DAMAGE.
NOTE: Whether or not the element conversion is made the
model rating plate must be marked. Using a hard point ink
pen, check the appropriate block within the model rating plate,
which is located adjacent to the lower access panel.
