MAINTENANCE
Shut off the electric power whenever the w ater supply to the w ater
heater is off. Shut off the electric power and water supply, drain the
heater completely to prevent freezing whenever the building is left
unoccupied during the cold weather months. In order to insure efficient
operation and long tank life, drain the w ater heater at least once a
month through the drain valve until the water runs clear. Failure to do
this may result in noisy operation and lime and sediment buildup in the
bottom of the tank. Check the temperature-pressure relief valve to
insure that the valve has not become encrusted w ith lime. Lift the lever
at the top of the valve several times until the valve seats properly
without leaking and operates freely.

technician at the minimum periodic intervals suggested below. In some
installations, the maintenance interval may be more frequent depending
