Service and Maintenance (cont’d)
Temperature-Pressure Relief
Valve Operation
The temperature-pressure relief valve must be manually
operated at least once a year.
TEMPERATURE-PRESSURE
RELIEF VALVE
DISCHARGE PIPE
Failure to install and maintain a new properly listed
temperature-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-pressure 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.
Thermostat Adjustments
The upper and/or lower thermostat(s) have been factory
set at HOT (approximately 120°F) to reduce the risk of
scald injury.
The upper and/or lower thermostat(s) are adjustable if a
different water temperature is desired. Read all warnings in
the “Temperature Regulation” section before proceeding.
NOTE: It is not necessary to adjust the upper
thermostat. However, if it is adjusted above the factory
set point of 120°F (HOT) it is recommended that it not
be set higher than the lower thermostat setting.
To adjust the temperature setting for both upper and lower
thermostats, proceed as follows:
1. Turn “OFF” the electric power to the water heater at the
junction box.
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.
Anode Rod Inspection
The anode rod is used to protect the tank from
corrosion. Most hot water tanks are equipped with an
anode rod. The submerged rod sacrifices itself to
protect the tank. Instead of corroding the tank, water
ions attack and eat away the anode rod. This does not
affect the water’s taste or color. The rod must be
maintained to keep the tank in operating condition.
Anode deterioration depends on water conductivity, not
necessarily water condition. A corroded or pitted anode
rod indicates high water conductivity and should be
checked and/or replaced more often than an anode rod
that appears to be intact. Replacement of a depleted
anode rod can extend the life of your water heater.
Inspection should be conducted by a qualified service
technician, and at a minimum should be checked
annually after the warranty period.
