Ariston ARI POU-06 Kullanım ve Bakım Kılavuzu

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.

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! To dissipate such gas

and reduce the risk of injury, it is recommended that the kitchen

sink hot water faucet be opened for several minutes before using

any electrical water heater connected to the hot water system.

If hydrogen is present, there will be an unusual sound, such as air

escaping through the pipe as water begins to flow. Do not smoke or

use an open flame near the faucet while it is open. Failure to follow

this warning could result in property damage, severe personal injury,

or death.

The maintenance activities described below are only to be performed

by the Installer / Qualified Service Provider. These maintenance

items should be performed during recommended annual service and

any service calls.

1. Ask the owner / user if there have been any issues with the water

heater. Diagnose any heater issues and repair / replace parts as

necessary.

2. Check the water heater and related plumbing for leaks. Repair any

that are found.

3. Check the area around the water heater for flammable liquids or

combustible materials. If any are found, remove from the area.

4. Check the heating element while the heater is in operation. If the

element is hissing / singing excessively, it may need to be cleaned.

Inspect the element and clean if necessary.

5. Inspect the Temperature and Pressure (T&P) Relief Valve. See

instructions below.

6. Turn power supply off to the water heater. Open the drain valve

and drain a few gallons of water from the tank to clear any hard water

deposits. Once complete, close the drain valve and restore power to

the water heater.

T&P Relief Valve Maintenance Instructions:

•

Annually: Certain naturally occuring mineral deposits may

adhere to the valve, blocking waterways and rendering the

valve inoperative. The T&P Relief Valve lever must be operated

to ensure the waterways are clear. If waterways are clear, hot

water will discharge from the valve. Take precautions to avoid

personal injury and property damage from contact with hot

water. Before operating lever, check to see that a discharge

line is connected to the valve, directing the flow of hot water

from the valve to a proper place of disposal.

•

Replacement of the valve is required if no water flows when

the lever is operated. Turn the water heater off until the valve

is replaced.

•

If water flows from the valve, drain a few gallons from the tank

to ensure the water flows freely.

•

At least once every three years: To ensure that the T&P

valve has not been affected by corrosive water conditions

and that the valve and discharge line have not been altered

or tampered with illegally, relief valves should be inspected,

and replaced, if necessary, by a licensed plumbing contractor

or qualified service technician.

Failure to comply with these guidelines could result in failure

of relief valve operation, and possibly result in substantial

property damage, severe personal injury, or death.

Leakage Checkpoints

A. *Condensation may be seen on pipes in humid weather or pipe

connections may be leaking.

B. The primary anode rod may be leaking.

C. Small amounts of water from the temperature / pressure relief

valve may be due to thermal expansion or high water pressure in

your area.

D. *The temperature / pressure relief valve may be leaking at the

tank fitting.

E. The element may be leaking at the tank fitting. Turn electrical

power "OFF", remove the access panels, insulation block, and pad.

If leaking is visible around the element, follow proper draining in-

structions and remove the element. Reposition or replace gasket on

element. Place element into opening and tighten securely. Then fol-

low "Filling the Heater" instructions, this manual.

F. Water from drain valve may be due to the valve being opened

slightly.

G. *The drain valve may be leaking from the tank fitting.

H. *Water in the water heater bottom or on the floor may be from

condensation, loose connections, or the temperature / pressure re-

lief valve. DO NOT replace the water heater until full inspections of

all possible water sources are determined and necessary corrective

steps have been taken.

NOTE: *To check the fitting threads, insert a cotton swab between

the jacket opening and fitting. If the cotton is wet, follow the drain-

ing instructions in the Maintenance section of this manual. Then re-

move the fitting. Put pipe dope or Teflon tape on the threads and

reinstall the fitting. Then follow "Filling the Heater" instructions, this

manual.
