Service and Maintenance (cont’d)

Thermostat Adjustments

The upper and lower thermostats have been factory set at HOT (approximately 120°F) to reduce the risk of scald injury.

The upper and lower thermostats 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.

2.Take off the access panel, insulation block and pad.

3.The slotted adjustment (using a screwdriver) can be turned

clockwise () to increase the temperature setting or

counter clockwise () to decrease the temperature setting.

4.Replace the insulation block, pad and access panel.

5.Turn “ON” the power supply.

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 nec- essarily water condition. A corroded or pitted anode rod indi- cates 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.

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

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.

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

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.
