WHEN ABNORMALLY HIGH WATER TEMPERATURES ARE PRESENT, IT IS IMPORTANT THAT A QUALIFIED SERVICE AGENT BE CONTACTED TO DETERMINE THE REASON FOR OPERATION BEFORE RESETTING.
MAINTENANCE
DRAINING
If the solar water heater is to be shut off and exposed to freezing temperatures, it must be drained. Water, if left in the tank and allowed to freeze, will expand and damage the solar water heater.
1. Turn “OFF” the electrical supply to the solar water heater.
WARNING
Make sure the electrical supply to the solar water heater is turned OFF. Failure to heed this will result in the possibility of
DEATH, SERIOUS BODILY INJURY OR PROPERTY DAMAGE.
2.Open a nearby hot water faucet until the water is no longer hot, then turn off the cold water supply and open the drain valve, leaving the hot water faucet open.
3.The drain valve must be left open during the
ELEMENT
In some water areas, scale or mineral deposits will build up on heating elements. This build up will cause a rumbling noise. Follow the element replacement directions to remove the elements from the tank. Soaking in vinegar and scraping will remove the mineral deposit. Be careful not to bend the element.
ELEMENT REPLACEMENT
WARNING
Replacement elements must (1) be the same voltage and
(2)no greater wattage than listed on the model and rating plate affixed to the solar water heater.
1. Turn OFF the electrical supply to the solar water heater.
WARNING
Make sure the electrical supply to the solar water heater is turned OFF. Failure to heed this will result in the possibility of DEATH, SERIOUS BODILY INJURY OR PROPERTY DAMAGE.
2.Drain the solar water heater. Follow the directions for draining.
3.Take off the access panel and turn back the insulation. Disconnect the wires from the heating element terminals.
4.Remove the element and gasket. You should always use a new gasket when you replace the element.
5.Install new element.
6.Reconnect the wires as they were.
7.Fill the tank , following the filling directions on page 5. Fill the tank with water, BEFORE you turn on the electric supply.
ANODE
The anode rod is used to protect the tank from corrosion. Most hot water tanks are equipped with an anode rod. The submerged rod sacrifices itself to protect the tank. Instead of corroding the tank, water ions attack and eat away the anode rod. This does not affect the water’s taste or color. The rod must be maintained to keep the tank in operating condition.
Anode deterioration depends on water conductivity, not necessarily water condition. A corroded or pitted anode rod indicates high water conductivity and should be checked and/or replaced more often than an anode rod that appears to be intact. Replacement of a depleted anode rod can extend the life of your water heater. Inspection should be conducted by a qualified technician, and at a minimum should be checked annually after the warranty period
Sometimes bacteria and mineral action on the anode will make the water smell. Chlorination of water supply will get rid of the odor. Equipment for treating problem water is available at your local hardware store.
WARNING
Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable and explosive. To prevent the possibility of bodily injury under these conditions, open the hot water faucet for several minutes at the kitchen sink before any electrical appliances which are connected to the hot water system are used (such as a dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it is opened.
