Frequently Asked Questions - ES025A3G WESTINGHOUSE

How to fill the water heater before first use?

Open the cold water supply valve to fill the tank, then open a hot water faucet to purge air. Once water flows steadily, close the hot water faucet. Check for leaks before plugging in the unit.

Why doesn't the indicator light turn on?

The indicator may be defective or the high temperature switch may have tripped. Check the reset button (section 7.2). If the light remains off but water heats, the bulb may be burned out.

How to adjust the water temperature?

Turn the knob on the front cover clockwise to increase temperature (max 145 °F) or counterclockwise to decrease (min 55 °F). A lower setting is more economical and reduces the risk of scalding.

What to do if brown or rusty water comes out of the faucet?

This indicates a worn anode and possible tank corrosion. Inspect and replace the anode (section 6.1). Also check the tank for signs of leaks.

How to drain the water heater?

Turn off the power supply. If the unit is connected with flexible hoses, turn it over a sink to empty the water. For a complete drain, remove the heating element (section 5.4).

How often should the anode be inspected?

At least once a year. A worn anode (pitted, rusted or absent surface) must be replaced to prevent tank corrosion. Failure to do so may void the warranty.

How to reset the high temperature switch?

Unplug the unit and remove the cover. Press firmly on the reset button (Fig. 9, [B]) with the tip of a pen. A click indicates reset. Reconnect and check operation.

What to do if the water heater leaks?

Check the water connections and T&P valve. Inspect the heating element gasket. If the tank leaks, contact customer service under warranty (if applicable). Replace the anode if necessary.

How to descale the heating element?

Remove the element (section 5.4) and soak it in white vinegar or a descaling solution. Rinse with fresh water and baking soda, or gently brush when dry with a non-metallic brush.

Why does hot water escape from the T&P valve?

This may be due to thermal expansion in a closed system. Install a diaphragm expansion tank of at least 0.5 gallon on the cold water line. Never block the valve.

Unclench the plastic shell in the back of water heater before hanging it, then align the two hanging holes on the back of the water heater with the two hooks of the water heater bracket and pull down with force to make the hanging holes hang into the hook.

CAUTION

The appliance must be hung securely to prevent personal injury and property damage from falling.

Floor mounting

• Heater can sit on floor. When the water heater is placed on the floor, additional reinforcement is required

3.2 Pipe connections

• Connect the cold water inlet pipe to the inlet tapping (marked with a blue ring).
• Ensure a isolation valve is installed on the cold water supply to the water heater.
• Connect the hot water outlet pipe to the outlet tapping (marked with a red ring).

CAUTION

To reduce the risk of excessive pressures and temperatures in this water heater:

Install the supplied temperature and pressure protective equipment required by local codes but not less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas Shut-off Devices for Hot Water Supply Systems,ANSIZ21.22.

The supplied temperature and pressure relief valve is marked with a maximum set pressure (150 psi) that does not exceed the marked maximum working pressure of the water heater.

Install the valve in the opening provided and marked for this purpose in the water heater.
- Orient it or provide tubing so that any discharge from the valve will exit within 6 inches above, or at any distance below, the structural floor, and cannot contact any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances.

NOTICE Wrap the

Wrap the Teflon tape around the threaded opening of the pressure relief valve at least 15 times (approximately 1.2 meters in length) in order to prevent water leakage.

Wrap at least 15 times

Teflon tape

NOTICE

Wrap at least 8 turns (approximately 25.2 inches (65~cm) ) of Teflon tape around the threaded opening of the hose connector.

National Plumbing codes may require a drain pan for the water heater installation. Failure to install one is the sole responsibility of owner and/or installer. Reference UPC (Uniform Plumbing Code), or IPC (International Plumbing Code).

3.3 Closed system thermal expansion

Periodic discharge of the temperature and pressure relief valve or failure of the element gasket may be due to thermal expansion in a closed water supply system. The water utility supply meter may contain a check valve, backflow preventer or water pressure reducing valve which will create a closed water system.

During the heating cycle of the water heater, the water expands causing pressure inside the water heater to increase.

The temperature and pressure relief valve may discharge hot water under these conditions which results in a loss of energy and a build-up of lime on the relief valve seat.

The temperature and pressure relief valve may discharge hot water under these conditions which results in a loss of energy and a build-up of lime on the relief valve seat.

To prevent this from happening, there are two recommendations:

• Install a diaphragm-type expansion tank that is suitable for potable water on the cold water supply line. A minimum 0.5 gallon expansion tank should be used.

Contact the local water supplier or plumbing inspector for information on how to control this situation. Do not plug the temperature and pressure relief valve.

4 Use

4.1 Starting and testing

CAUTION

DO NOT supply power to water heater until filled with water.

To fill the heater:

• Open supply valve for water heater to fill with water.
• Open hot water tap(s) supplied by the water heater to purge air out of the system. Once air is purged, close hot water tap.
  Visually check for any leaks.

Turning heater on

For models which are not fitted with a switch:

Supply power to the water heater by plugging in the power cord.

If the light does not come on, turn the control knob in a clockwise direction.

The light will come on until water temperature has reached the thermostat temperature setting. The light will come back on any time the water temperature inside the tank drops below the thermostat setting.

DANGER

If user's water pressure is high, TP valve may relieve pressure under high pressure during the heating process, water temperature will be over 145^ after pressure relief, which can cause severe burns instantly or death from scalds. Please take attention!

4.2 Temperature setting

To fill the heater:

The temperature of the hot water is adjusted by rotating the knob M (Fig.5) located on the front cover. Temperature range is 55 - 145^ .

5.3 Inspecting the anode rod

If the heater has been installed with flexible hoses:

The purpose of the anode rod (Fig. 8, [N]) is to protect the tank against corrosion. It is critical that the anode rod be inspected once a year to determine whether it requires replacement. To access the anode rod, the heating element must be removed (see Section 5.4 Removing the heating element). Upon inspection, the anode rod surface should appear smooth. If the rod surface appears pitted, bumpy, rusty, or if the rod is

missing completely, then it must be replaced.

To access the anode rod:

• Remove the heating element (see Section 5.4 Removing the heating element).

Original anode rod sizes

Length 4.72" Diameter 0.787"

Certain installations may require more frequent replacement of the anode rod:

recirculation applications
- poor water quality
galvanic/electrolytic corrosion
high flow applications

In the event of poor water quality, we recommends consulting a local water treatment professional for water treatment options. Always ensure the water heater is grounded. Damage resulting from poor water quality or failure to replace the anode rod is not covered under the manufacturer's warranty. For additional questions, please call Technical Service.

7 Troubleshooting

7.1 Fault Assessment and Troubleshooting

Problem Solution
Water does not get hot	Make sure the power supply is on and working.
	If light does not come on, check that the high limit reset button is pushed in; follow steps in section 7.1.
	If the indicator light works properly but temperature does not get hot at the tap, test for a plumbing crossover; shut off cold supply to heater and open hot water tap. There should be no water flowing. Any continued flow indicates a crossover which will effect the temperature and will need to be corrected.
	Call a qualified service technician to test the resistance of the heating element (8-10 ohms). Heating element should be replaced if readings are outside these values.
Light not on	If the light does not come on, but water gets hot, check for faulty bulb.
	Check high limit reset button; follow steps in section 7.2.
Brown water	Brown or rusty water indicates a "spent" anode rod and possible deterioration of the tank body. Inspect the tank for leaks. Check anode rod (see section on changing the anode rod).
Leaking	Check water fittings and T & P fitting on top of tank. Remove front cover and inspect heating element gasket.
	If tank is leaking call Fogatti Water Heating for warranty claim if still within warranty period.
	Check anode rod (see section on changing the anode rod).

7.2 Resetting High Limit Switch

Occasionally, the high temperature limit shut off device may trip the reset. This occurs when water temperature exceeds 190^ . The shut off device may also trigger from a power outage or electrical storm. To reach the thermostat:

• Disconnect power cord and remove installation cover.
  Firmly press reset button (Fig. 9, [B]) with the tip of a ball point pen or similar object.

Fig. 9

A click indicates the reset was tripped.

Reconnect power
IMPORTANT:
Check the operation of the thermostat: Turn temperature dial from high to low.
If the red light does not go off on low setting: Turn off power supply and call a service person to replace the thermostat.
If the red light does go off the thermostat is working well: Place dial setting to desired setting.

NOTICE

A lower setting is more economical and reduces the risk of scalding.

Replace cover plate.
