American Water Heater 318281-000 사용자 설명서

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 shut-down

period. Once the solar water heater is drained close the

hot water faucet.

ELEMENT

In some water areas, scale or mineral deposits will build up

on heating elements. This build up may 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

Replacement elements must (1) be the same voltage and

(2) no greater wattage than listed on the model and rating

plate affi xed to the solar water heater.
1. Turn OFF the electrical supply to the solar water heater.
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 take off the access panel

and remove the insulation.Disconnect the wires from the

heating element terminals.

4. Use and element wrench to 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 9. Fill

the tank completely with water, BEFORE you turn on the

electric supply.

ANODE

Each water heater contains at least one anode rod, which

will slowly deplete (due to electrolysis) prolonging the life

of the water heater by protecting the glass-lined tank from

corrosion. Adverse water quality, hotter water temperatures,

high hot water usage, hydronic heating devices, and water

softening methods can increase the rate of anode rod

depletion. Once the anode rod is depleted, the tank will

start to corrode, eventually developing a leak.

Certain water conditions will cause a reaction between the

anode rod and the water. The most common complaint

associated with the anode rod is a “rotten egg smell”

produced from the presence of hydrogen sulfide gas

dissolved in the water. IMPORTANT: Do not remove this rod

permanently as it may void any warranties. A special anode

rod may be available if water odor or discoloration occurs.

NOTE: This rod may reduce but not eliminate water odor

problems. The water supply system may require special

filtration equipment from a water conditioning company to

successfully eliminate all water odor problems.

Artificially softened water is exceedingly corrosive because

the process substitutes sodium ions for magnesium and

calcium ions. The use of a water softener may decrease

the life of the water heater tank.

The anode rod should be removed from the water heater

tank every 3 years for inspection. NOTE: artificially softened

water requires the anode rod to be inspected annually.

The following are typical (but not all) signs of a depleted

anode rod:
• The majority of the rod’s diameter is less than 3/8”.
• Significant sections of the support wire (approx. 1/3 or

more of the anode rod’s length) are visible.
If the anode rod shows signs of either or both it should be

replaced. NOTE: Whether re-installing

or replacing the anode rod, check for

any leaks and immediately correct if

found.
In replacing the anode:

Turn off power supply to the water

heater.
Shut off the water supply and

open a nearby hot water faucet to

depressurize the water tank.
Drain approximately 5 gallons

of water from tank. (Refer to

“Draining and Flushing” for proper

procedures). Close drain valve.
Remove old anode rod.

Use Teflon® tape or approved pipe

sealant on threads and install new anode rod.
Turn on water supply and open a nearby hot water

faucet to purge air from water system. Check for any

leaks and immediately correct any if found.
Restart the water heater as directed in this manual.

See the Storage Tank Repair Parts section for anode

rod location.

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.
WATER HEATER SOUNDS

1. The solar water heater is equipped with an immersion

heating element for fastest recovery. If the solar water

heater occasionally makes noises this is not a defect or a

safety hazard.

2. Lime or scale has accumulated on the heating element

causing a hissing sound. Element scale removal can be

accomplished by using vinegar or by scraping.
