Draining and Flushing
The water heater should be drained if being shut down during freezing temperatures. It is recommended that the tank be drained, and fl ushed every 6 months to remove sediment which may buildup during operation. To drain the tank perform the following steps:
1.Disconnect the electrical power to the water heater.
2.Open a hot water faucet until water is no longer hot.
3.Close the cold water inlet valve and open a hot water faucet.
4.Connect a hose to the drain valve and terminate it to an adequate drain.
5.Open the water heater drain valve and the nearest hot water faucet. Allow all the water to drain from the tank. Flush the tank with water as needed to remove sediment.
6.Close the drain valve and completely refill the water heater tank.
7.Reconnect electrical power to the water heater.
If the water heater is going to be shut down for an extended period, the drain valve should be left open.
Heating Element Replacement
WARNING
Electric Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
Replacement heating elements must be of the same style and voltage/wattage rating as the ones presently in the water heater. This information can be found on the fl ange or terminal block of the element or on the water heater data plate.
1.Disconnect the electrical power to the water heater.
2.Drain the water heater as directed in the “Draining and Flushing” section.
3.Remove the access cover(s). Fold up the insulation from the heater element(s). Remove the plastic thermostat cover from the thermostat(s) making sure to disengage the attachment point from the thermostat.
4.Disconnect the electrical wires from the heating element(s) by loosening the screws (Figure 13). Remove the
