Care and cleaning of the water heater.
Draining the Water Heater
CAUTION: Shut off power to the water heater before draining water.
DANGER: Before manually operating the relief valve, make certain no one will be exposed to the hot water released by the valve. The water drained from the tank may be hot enough to present a scald hazard and should be directed to a suitable drain to prevent injury or damage.
In order to drain the water heater, turn off the cold water supply. Open a hot water faucet or lift the handle on the relief valve to admit air to the tank.
Attach a garden hose to the drain valve on the water heater and direct the stream of water to a drain. Open the valve.
Routine Preventative Maintenance
WARNING: Disconnect all power to unit before starting maintenance. Failure to do so can cause electrical shock resulting in severe personal injury or death.
DANGER: Before manually operating the relief valve, make certain no one will be exposed to the danger of coming in contact with the hot water released by the valve. The water may be hot enough to create a scald hazard. The water should be released into a suitable drain to prevent injury or property damage.
NOTICE: If the temperature and pressure relief valve on the hot water heater discharges periodically, this may be due to thermal expansion in a closed water system. Contact the water supplier or your plumbing contractor on how to correct this. Do not plug the relief valve outlet.
Properly maintained, your water heater will provide years of dependable
It is suggested that a routine preventive maintenance program be established and followed by the user.
It is further recommended that a periodic inspection of the electronic control, heat pump and wiring should be made by service personnel qualified in electric appliance repair.
Most electrical appliances, even when new, make some sound when in operation. If the hissing or singing sound level increases excessively, Contact a qualified installer or plumbing contractor to inspect.
IMPORTANT: See "DANGER on left". At least once a year, lift and release the lever handle on the temperature pressure relief valve, located on the side of the water heater, to make certain the valve operates freely. Allow several gallons to flush through the discharge line to an open drain.
It is recommended to clean the filter on top of the heat pump every month. Clean by washing with mild detergent and water. Dry and replace over discharge fan. Remove the filter by lifting up on the handle at front of the heat pump and lifting it off the air discharge fan. See Figure on right.
A water heater’s tank can act as a setting basin for solids suspended in the water. It is therefore not uncommon for hard water deposits to accumulate in the bottom of the tank. It is suggested that a few quarts of water be drained from the water heater’s tank every month to clean the tank of these deposits.
Rapid closing of faucets or solenoid valves in automatic water using appliances can cause a banging noise heard in a water pipe. Strategically located risers in the water pipe system or water hammer arresting devices can be used to minimize the problem.
