Draining
The water heater should be drained if being shut down during
freezing temperatures. Also periodic draining and cleaning of
sediment from the tank may be necessary.
1. Before beginning turn “OFF” the electric power supply to
the water heater.
2. CLOSE the cold water inlet valve to the water heater.
3. OPEN a nearby hot water faucet and leave open to allow
for draining.
4. Connect a hose to the drain valve and terminate to an ade-
quate drain or outdoors.
5. OPEN the water heater drain valve to allow for tank
draining.
NOTE: If the water heater is going to be shut down and
drained for an extended period, the drain valve should be
left open with hose connected allowing water to termi-
nate to an adequate drain.
6. Close the drain valve.
7. Follow “Filling the Water Heater” instructions in the
“Instructions for Installation” section.
8. Turn “ON” power to the water heater.
WARNING
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.
CAUTION
Never use this water heater unless it is completely
full water. To prevent damage to the tank and heat-
ing element, the tank must be filled with water.
Water must flow from the hot water faucet before
turning “ON” power.

Service and Maintenance
Temperature-Pressure Relief
Valve Operation
The temperature-pressure relief valve must be manually oper-
ated at least once a year.
TEMPERATURE-PRESSURE
RELIEF VALVE
DISCHARGE PIPE
Failure to install and maintain a new properly listed tempera-
ture-pressure relief valve will release the manufacturer from
any claim which might result from excessive temperature or
pressure.
WARNING
The temperature-pressure relief valve must be
manually operated at least once a year. Caution
should be taken to ensure that (1) no one is in front
of or around the outlet of the temperature-pres-
sure relief valve discharge line, and (2) the water
manually discharged will not cause any property
damage or bodily injury. The water may be
extremely hot.
If after manually operating the valve, it fails to
completely reset and continues to release water,
immediately close the cold water inlet to the water
heater, follow the draining instructions, and
replace the temperature-pressure relief valve with
a new one.
WARNING
If the temperature-pressure relief valve on the
appliance weeps or discharges periodically, this
may be due to thermal expansion. Your water
heater may have a check valve installed in the
water line or a water meter with a check valve. Call
Maytag Customer Service at 1-800-788-8899 for an
authorized servicer. Do not plug the temperature-
pressure relief valve.
