4.Close and lock the electrical control panel door.

5.Turn on the main electrical power to the water heater.

6.Temperature control and contactor operation should be checked by allowing the water heater to come up to temperature and shut off automatically.

7.The water heater is now ready continuous normal operation.

SHUTDOWN PROCEDURE

Draining the Water Heater

1.Turn off the main electrical power to the water heater. If the power disconnect point is out of sight, lock it in the open (“OFF”) position and tag to prevent unexpected application of power.

2.Turn the valve in the water heater’s cold water supply to the closed or “OFF” position.

3.Turn the valve in the water heater’s hot water outlet to the closed or “OFF” position.

4.Manually open the temperature and pressure relief valve to remove any pressure from the storage tank.

CAUTION: Any water discharged from the manually opened relief valve may be hot

and cause a scald injury.

5.Allow the system to cool and then open the drain valve to empty the storage tank. It will be necessary to manually hold the temperature and pressure relief valve in the open position to break the vacuum in the tank and allow it to vent and drain. Insure that the water heater drain is routed to a properly sized floor drain to allow the water to be removed from the tank. If a floor drain is not available, a hose may be attached to the water heater drain to take the water outdoors.

6.The water heater is now shut down and ready for service or maintenance.

7.Follow the filling and start up procedure to place the water heater back into service.

MAINTENANCE

Listed below are items that must be checked to insure safe reliable operations. Verify proper operation after servicing.

WARNING:

HAZARD OF ELECTRICAL SHOCK – Before opening the access panel to perform service on any electrical component, 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:

Label all wires prior to

disconnection

when servicing controls.

Wiring errors can cause improper and dangerous operation.

TEMPERATURE AND PRESSURE

RELIEF VALVE OPERATION

The temperature and pressure relief valve(s) should be manually operated at least once a year. A relief valve that fails to completely reseat after manual operation and continues to discharge water must be immediately replaced with a new, properly sized, temperature and pressure relief valve.

The relief valve(s) should be installed in the vertical position and mounted in the tapping provided in the storage tank. No valve should be placed between the relief valve, and the water heater. To prevent water damage, the discharge from the relief valve must be piped to a suitable floor drain for disposal when relief occurs. No reducing couplings or other restrictions shall be installed in the discharge line. The discharge line shall allow complete drainage of the valve and line. The discharge line from the relief valve
