AWARNING
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 iine, and (2) the water
manually discharged will not cause any property
damage or bodiiy 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.
LOWER THERMOSTAT
The adjustment dial can be turned clockwise {/' \) to
increase the temperature setting or counter clockwise
{jT ^) to decrease the temperature setting.
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.
AWARNING
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-
