C. Heating Element Replacement Procedure

If heating elements need replacement, it is very important to use the

same voltage, wattage, and construction. DO NOT replace heating

element with a generic heating element. Only Ariston heating

elements are approved for use with this water heater. Failure to

follow this warning will result in premature product failure and VOID

the warranty, and could result in severe personal injury or death.

STEP #1 - Turn off power to the water heater. Use a Phillips Head

screwdriver to remove the wires from the element.

Failure to disconnect the power from the water heater before

attempting heating element replacement will result in property

damage, severe personal injury, or death due to electric shock.

STEP #2 - Run hot water at a faucet in the system. When it runs cold,

shut off the faucet. Then shut off water at the main cold water inlet or,

if possible, valve off the water heater from the system. Drain the water

from the system, or just the water heater if it can be isolated from the

system.

Completely drain the water heater before removing and replacing a

heating element or elements. Failure to do so will result in a leakage

of water and property damage, and could possibly result in moderate

to severe personal injury or death.

Water drained from the water heater may be scalding hot. Take care

to avoid scalding. Wear gloves and safety glasses, and direct water to

a safe drainage location. Failure to comply with this warning could

result in property damage, severe personal injury, or death.

Step #3 - Remove the element with a 1 1/2" socket wrench or element

tool.

Step #4 - Inspect the removed element. Determine whether the

replacement element will need a square or circular gasket and washer.

Step #5 - Ensure thread and opening are completely free of debris. Use

a nylon brush to clear away any debris.

Figure 7 - Heating Element Detail

Step #6 - Put a small amount of NSF approved lubricant and sealant

on the appropriate gasket and/or washer for the installation. Put the

gasket and/or washer on the element.

Step #7 - Screw the element clockwise into the tank, and tighten with

the 1 1/2" socket wrench or element tool. Be sure gasket seats properly.

NOTE: Repeat Steps 3 - 6 as Necessary for Multiple Elements

Step #8 - Open the main cold water inlet. If the water heater has been

isolated from the system, open the valves. Refill the tank with cold

water. Open a hot water faucet high in the system to bleed any air

pressure from the system. Water will flow freely when air is completely

bled.

When filling the water heater, open a hot water tap to release air

in the tank and piping. The tank must be full of water before the

heater is turned on. Failure to ensure the water heater is full before

turning it on will result in damage to the water heater, and could

result in property damage, serious personal injury, or death. Such

damages ARE NOT covered by water heater warranty.

Step #9 - Pressure check the tank for leaks around element. If no

leaks are found, use a Phillips Head screwdriver to connect the wires

to the element.

Step #10 - Turn power back on to the water heater.

Failure to refill the tank before restoring power to the water

heater will result in damage to the heating elements and property

damage. Such damages ARE NOT covered by warranty.

Part 7 - Maintenance

Considerations

•

To avoid electric shock, disconnect electrical supply before

performing maintenance.

•

To avoid severe burns, allow heater to cool before

performing maintenance.

NOTE: In addition to the routine maintenance detailed in this

manual, this water heater should be inspected annually by a

qualified service technician to assure that all the equipment is

operating safely and efficiently. The owner should make necessary

arrangements with a qualified heating contractor for periodic

maintenance of the heater. Installer must also inform the owner

that lack of proper care and maintenance may result in a hazardous

condition, premature heater failure, and void the warranty.

Routine preventative maintenance ensure the water heater

operates safely and efficiently over its service life. The Owner / User

may perform the maintenance activities described below.

Monthly (Every two weeks in hard water locations)

It is recommended that a few quarts of water be drained from the

heater. This will flush sediment deposits from the bottom of the

heater and lengthen the heater's service life. Turn off power to

the heater during flushing operation, so the elements will not be

damaged.

Failure to shut off the heater when draining may damage the

heating elements. Operating a partially filled / empty water

heater could lead to damage from "dry-firing". Failures due to such

damage ARE NOT covered by warranty.

Water drained from the water heater may be scalding hot. Take

care to avoid scalding. Wear gloves and safety glasses, and direct

water to a safe drainage location. It is recommended to turn

power off to the water heater and run water at a hot water faucet

until it cools BEFORE draining water from the heater. Failure to

comply with this warning could result in property damage, severe

personal injury, or death.

To flush the tank, attach a hose to the field installed drain valve.

Close the cold water supply line shut-off valve. Open the drain valve

and hot water faucet(s) to vent heater while draining. Direct the flow

of water to a drain or bucket where it will not cause damage.

Flush until water runs clear to complete this operation. Close drain

valve and reopen the supply line shut-off valve. Close the hot water

faucet(s) once all air has been bled from the system (when water
