SECTION III - SCHEDULED MAINTENANCE AND OPERATION

WARNING / CAUTION

Before performing any maintenance procedure, make certain power supply is OFF and cannot accidentally be turned on.

MAINTENANCE AND OPERATION

The heater is automatic in its operation. It will maintain water at the temperature setting of the thermostat. The heater should not be turned on without first making sure that the vessel is full of water and that all air has been released.

FREEZING

The vessel should be fully drained in the event the electricity has been turned off and if there is danger of freezing.

QUARTERLY INSPECTION

1.Monitor thermostat

a.Let water heater completely heat to a designated thermostat setting.

b.After thermostat satisfies (that is, when the thermostat actually clicks off), draw water from heater.

c.Compare water temperature of drawn water to the temperature setting of the thermostat when it satisfies. Normal variation between the two points is approximately + 5°F.

d.If these two readings do not coincide within acceptable tolerances and verification has been made of the accuracy of the temperature-reading gauge, replace the thermostat.

2.Lift test lever on relief valve and let water run through valve for a period of approximately 10 seconds. This will help flush away any sediment that might build up in water passageways.

3.Inspect element flange for leakage as follows:

a.Shut off Power Supply.

b.Remove element housing cover.

c. Visually inspect heating element gasket for evidence of leaks.

d.Rub finger around gasket that is between the heating element and tank flange for any evidence of moisture. If moisture is present or a water drip is observed, follow procedure outlined in Section V.

4.Check for loose electrical connections. Tighten as necessary.
