Table 3 – Electrical Specifications Including Corresponding Wattages / Voltages / Amperages
NOTE: In the State of California, the water heater must be braced, anchored, or strapped to avoid moving during an earthquake. Contact local utilities for code requirements in your area. Visit http://www.dsa.dgs.ca.gov or call 1-916-445-8100 and request instructions.
However, applicable local codes shall govern installation. For residential water heaters of a capacity of greater than 52 gallons, consult the local building jurisdiction for acceptable bracing procedures.

Check area around water heater. Remove any combustible materials, gasoline, and other flammable liquids.

DANGER
This water heater must not be located near flammable liquids such as gasoline, butane, liquefied propane, adhesives, solvents, paint thinners, etc., as the controls of this water heater could ignite these vapors and cause an explosion resulting in property damage, severe personal injury, or death.

If the water heater is to replace an existing water heater, check for and correct any existing system problems such as:
- System leaks
- Location that could cause the system and water heater to freeze and leak
- Incorrectly-sized expansion tank
This water heater must be installed vertical on a level surface.

C. Water Chemistry Requirements

CAUTION
Chemical imbalance of the water supply may affect efficiency and cause severe damage to the water heater and associated equipment. Westinghouse recommends having water quality professionally analyzed to determine whether it is necessary to install a water softener. It is important that the water chemistry on both the domestic hot water and central heating sides are checked before installing the water heater, as water quality will affect the reliability of the system. In addition, operating temperatures above 135oF will further accelerate the build-up of lime scale and may shorten the service life of the water heater. Failure of a water heater due to lime scale build- up, low pH, or other chemical imbalance IS NOT covered by the warranty.

Outlined below are water quality parameters that need to be met in order for the system to operate efficiently for many years. Water Hardness Water hardness is mainly due to the presence of calcium and magnesium salts dissolved in water. The concentration of these salts is expressed in mg/L, ppm, or grains per gallon as a measure of relative water hardness. Grains per gallon is the common reference used in the US water heater industry. Hardness expressed as mg/L or ppm may be divided by 17.1 to convert to grains per gallon. Water may be classified as very soft, slightly hard, moderately hard, or hard based on its hardness number. The minerals in the water precipitate out as the water is heated and cause accelerated lime scale accumulation on a heat transfer surface. This lime scale build-up may result in premature failure of the water heater.
Water that is classified as hard and very hard must be softened whl-026 Rev. 4.28.1 to avoid water heater failure.

CLASSIFICATION	MG/L OR PPM	GRAINS/GAL
Soft	0 – 17.1	0 – 1
Slightly Hard	17.1 – 60	1 – 3.5
Moderately Hard	60 – 120	3.5 – 7
Hard	120 – 180	7 – 10.5
Very Hard	180 and over	10.5 and over

If the hardness of the water exceeds the maximum level of 12 grains per gallon, the water should be softened to a hardness level no lower than 5 grains per gallon. Water softened as low as 0 to 1 grain per gallon may be under-saturated with respect to calcium carbonate, resulting in water that is aggressive and corrosive.

pH of Water
pH is a measure of relative acidity, neutrality, or alkalinity. Dissolved minerals and gases affect water pH. The pH scale ranges from 0 to 14. Water with a pH of 7 is considered neutral. Water with pH lower than 7 is considered acidic. Water with a pH higher than 7 is considered alkaline. A neutral pH (around 7) is desirable for most potable water applications. Corrosion damage and tank failures resulting from water pH levels of lower than 6 or higher than 8 ARE NOT covered by warranty. The ideal pH range for water used in a water heater is 7.2 to 7.8.

Total Dissolved Solids
Total Dissolved Solids (TDS) is a measurement of all minerals and solids dissolved in a water sample. The concentration of TDS is usually expressed in parts per million (ppm).
Water with a high TDS concentration will greatly accelerate lime and scale formation in the hot water system. Most high TDS concentrations precipitate out of the water when heated. This can generate a scale accumulation that will greatly reduce the service life of the water heater.
The manufacturer of the water heater has no control over water quality, especially TDS levels in your system. TDS in excess of 2000 ppm will accelerate lime and scale formation on the element or the heat exchanger. Water heater failure due to TDS in excess of 2000 ppm IS NOT covered by warranty.

Failure of a water heater due to lime scale build-up IS NOT covered by warranty.

Hardness: Less than 12 grains
Chloride levels: Less than 100 ppm
pH levels: 6 – 8
TDS: Less than 2000 ppm
Sodium: Less than 20 mG/L

CAUTION
Failure of electric elements due to lime scale build-up on the heating surface, low pH, or other imbalance IS NOT covered by the warranty.

Part 3 – Piping

A. Plumbing
It is mandatory that all plumbing be done in accordance with federal, local, and state plumbing codes and practices. Failure to properly install the water heater WILL VOID the warranty. It is also necessary to use both thread tape and pipe sealing compound on all mechanical plumbing connections.
It is recommended to use unions on the hot and cold water connections to easily disconnect the water heater for servicing.

CAUTION
Dielectric unions or galvanized steel fittings must not be used in a system with this water heater. Doing so WILL VOID the warranty. It is recommended to use only copper, brass, or stainless steel fittings. Teflon thread sealant must be used on all connections.

Install a shut-off or check valve or both on the inlet connection on the top of the heater. Connect the cold water supply line to the shut-off valve or check valve. Refer to piping Applications, this manual.

CAUTION
Do not apply heat to the Hot or Cold water heater connections. If sweat connections are used, sweat tubing to the adapter before fitting adapter to the water connections on the heater. Any heat applied to the water heater connections will permanently damage the dip tube and/or heat traps. Damages due to improper installation practices ARE NOT covered by warranty.

Connect the hot water line to the connection marked “HOT” on the top of the water heater.
Install the T&P Valve in the opening provided near the top of the heater.
Install drain valve in the opening provided near the bottom of the heater.

B. Thermal Expansion

A check valve may be installed in the cold water inlet line as a separate backflow preventer, or may be part of a pressure reducing valve, water meter, or water softener. An “open water system” refers to a system without a check valve. A “closed water system” refers to a system with a check valve installed in the cold water inlet line.
As water is heated, it expands in volume and increases pressure within the water system. This action is referred to as “thermal expansion”. In an open water system, expanding water which exceeds the capacity of the system flows back into the city main where pressure is easily dissipated.
A closed water system prevents expanding water from flowing back to the city main. The resulting thermal expansion can rapidly increase pressure in the water heater and system piping. This rapid pressure increase can exceed the setting of the pressure relief valve, causing it to operate during each heating cycle, resulting in discharge from the T&P. This rapid and repeated expansion and contraction of components in the system can cause premature failure of system components, including the relief valve and possibly the water heater.
Replacing the relief valve will not correct thermal expansion. A potable hot water expansion tank is required to offset thermal expansion. Expansion tanks are designed with an air cushion built in that compresses as system pressure increases, thereby relieving the overpressure condition and eliminating repeated operation of the relief valve. This expansion tank should be installed in the cold water line between the water heater and check valve, and must be sized for the entire water volume of the hot water system. See piping Applications.
Other methods of controlling thermal expansion are available. Check with the local water utility to determine if a check valve exists in the cold water inlet line. Contact your installing contractor, water supplier, or plumbing inspector for additional information regarding thermal expansion.

C. Condensation
Condensation can form on the water heater when it is first filled with water, and may also occur with a heavy water draw and very cold inlet water temperature. This condition is not unusual and will disappear as the water becomes heated. However, if the condensation should continue, examine the piping and fittings for possible leaks.

D. Insulation Blankets

WARNING
If local codes require external application of insulation blanket kits, the manufacturer’s instructions included with the kit must be carefully followed.
In addition, pay careful attention to the following so as not to restrict the proper function and operation of the water heater:

Do not cover the operating or warning labels attached to the water heater or attempt to locate them on the exterior of the insulation blanket.
Do not apply insulation to the top of the water heater. This could interfere with the safe operation of the electrical junction box.
Do not cover the jacket access panel(s) to the thermostat(s) and heating element(s) or T&P valve.
Inspect the insulation blanket frequently.
Failure to follow these instructions could result in property damage, severe personal injury, or death.

E. Temperature and Pressure Relief Valve

For protection against excessive pressures and temperatures in this water heater, install temperature and pressure protective equipment as required by local codes, but not less than a combination T&P valve meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22B / CSA 4.4-M99 by a nationally recognized testing laboratory that maintains periodic inspection of production listed equipment and materials. This valve must be marked with a maximum set pressure not to exceed the marked maximum working pressure of the water heater. Install the T&P valve into the opening provided and marked for this purpose on the water heater. The T&P valve must be plumbed down so discharge can exit at least 6” above the structural floor. The relief line cannot be in contact with any live electrical parts.

WARNING

To avoid water damage or scalding due to relief valve operation:

Discharge line must be connected to relief valve outlet and run to a safe place of disposal. Terminate the discharge line in a manner that will prevent possibility of severe burns or property damage should the relief valve discharge.
Discharge line must be as short as possible and the same size as the valve discharge connection throughout its entire length.
Discharge line must pitch downward from the valve and terminate at least 6” above the floor drain, making discharge clearly visible.
The discharge line shall terminate plain, not threaded, with a material serviceable for temperatures of 375oF or greater.
Do not pipe discharge to any location where freezing could occur.
No valve may be installed between the relief valve and heater or in the discharge line. Do not plug or place any obstruction in the discharge line.
Test the operation of the relief valve after filling and pressurizing the system by lifting the lever. Make sure the valve discharges freely. If the valve fails to operate correctly, immediately replace with a new properly rated relief valve.
Test T&P valve at least once annually to ensure the waterway is clear. If valve does not operate, turn the heater “off” and call a plumber immediately.
Take care whenever operating relief valve to avoid scalding injury or property damage.

FAILURE TO COMPLY WITH THE ABOVE GUIDELINES COULD RESULT IN FAILURE OF RELIEF VALVE OPERATION, RESULTING IN POSSIBILITY OF SUBSTANTIAL PROPERTY DAMAGE, SEVERE PERSONAL INJURY, OR DEATH.

RE-INSPECTION OF T &P RELIEF VALVES: T&P valves should be inspected AT LEAST ONCE EVERY THREE YEARS, and replaced if necessary, by a licensed plumbing contractor or qualified service technician to ensure that the product has not been affected by corrosive water conditions and to ensure that the valve and discharge line have not been altered or tampered with illegally. Certain naturally occuring conditions may corrode the valve and its components over time, rendering the valve inoperative. Such conditions can only be detected if the valve and its components are physically removed and inspected. Do not attempt to conduct an inspection on your own. Contact your plumbing contractor for a re-inspection to assure continued safety.

FAILURE TO RE-INSPECT THE T&P VALVE AS DIRECTED COULD RESULT IN UNSAFE TEMPERATURE AND/OR PRESSURE BUILD-UP WHICH CAN RESULT IN PROPERTY DAMAGE, SERIOUS PERSONAL INJURY, OR DEATH.

Do not thread a cap or plug into the relief valve or block relief valve outlet line under any circumstances! Explosion and property damage, serious injury, or death may result.

F. Scalding

WARNING

An ASSE 1017 or ASSE 1070 temperature limiting or mixing valve is recommended in installations servicing disabled or elderly persons, or children. Mixing valves can reduce but do not eliminate the risk of scalding.
To avoid scalding:

Set the water heater set point temperature as low as possible.
Feel water before bathing or showering.
If thermostatic valves are required, use devices specifically designed for such purpose. Install these devices in accordance with instructions provided by the manufacturer.

Failure to install a temperature limiting or mixing valve and follow these instructions could result in property damage, severe personal injury, or death due to scalds.

This water heater can deliver scalding water. Be careful whenever using hot water to avoid scalding injury. Certain appliances such as dishwashers and automatic clothes washers may require increased water temperatures. By setting the thermostat on this heater to obtain the increased water temperature required by these appliances you may create the potential for scald injury.

To protect against injury, install a mixing valve in the water system. This valve will reduce point of use discharge temperatures by mixing cold and hot water in branch supply lines. Such valves are available from your local plumbing supplier.
Table 1 details the relationship of water temperature and time with regard to scald injury and may be used as a guide in determining the safest water temperature for your applications.

G. Filling the Heater

Make certain that the drain valve is completely closed.
Open the shut-off valve in the cold water supply line.
Open the hot water faucets to allow air to vent from the heater and piping.
Allow sufficient time for the heater to completely fill with water.
Verify elements are installed correctly. Check for leaks.

CAUTION

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 could result in damage to the water heater and other property damages. Such damages ARE NOT covered by water heater warranty.

H. Applications

Westinghouse-WEC080C2X-Electric-Water-Heater-FIG-4

The following notes are applicable to all of the piping applications demonstrated on this page.

Minimum pipe size should match connection size. Upsize pipe accordingly if greater flow is required.
A thermal expansion tank suitable for potable water must be sized and installed within this piping system between the backflow preventer and the cold water inlet.
All circulators should have an integral flow check.
Drains and check valve between unit and storage tank will assist in purging air from system.
These drawings are meant to demonstrate system piping only. The installer is responsible for all equipment and detailing required by local codes. In Massachusetts, you must install a vacuum relief valve per 248 CMR.
Mixing valve application is optional, but recommended to help prevent scalding. See Part 3 for more information.

Part 4 – Wiring

CAUTION
Tank must be full of water before the power is turned on. Heating elements will be damaged if energized for even a short time while tank is dry. Failures due to “dry-firing” ARE NOT covered by warranty.

This unit is factory wired to a junction box on top of the water heater for field wiring connection. These heaters are equipped and wired for the maximum possible input allowable (see Table 3 for listing of inputs and amperage requirements). The voltage requirement and dedicated wattage load for the heater is specified on the rating label of the water heater. Consult your local power company to determine if your electrical service is adequate for the additional load of the heater.
Refer to the wiring diagrams for field connections. All wiring must conform to local code and the National Electric Code, and should be done by a qualified licensed electrician or the local electric utility. Grounding can be accomplished
by using approved conduit and fittings or other approved conductive material. A grounding wire is provided on the junction bracket. This grounding wire must be used in the installation.

WARNING
Be sure to ground the water heater. The preferred way to ground is with rigid metal conduit between the main panel and the water heater junction box with approved end fittings (check codes on the use of flexible conduit). If making a separate ground, a green ground wire is provided in the water heater junction box. Replace the junction box cover and insulation after you have made the wiring connections. Failure to follow these instructions could result in property damage, severe personal injury, or death.

Part 5 – Installation Checklist

Part 6 – Operation

CAUTION
Tank must be full of water before the power is turned on. Heating elements will be damaged if energized for even a short time while tank is dry. Failures due to “dry-firing” ARE NOT covered by warranty.

After water and electrical connections have been made and tank is filled with water, turn on power to the heater. The heater is now in operation.

A. Combination Thermostat and High Limit Control (ECO)
Each water heater is equipped with a combination Thermostat – High Limit Control (ECO). Thermostats are located above the heating elements. If for any reason the water temperature becomes excessively high, the ECO breaks the circuit to the heating element. Once the switch opens it must be reset manually. However, THE CAUSE OF THE OVER TEMPERATURE CONDITION MUST BE CORRECTED FIRST.

WARNING
The cause of the high temperature condition must be investigated by a qualified service technician and corrective action must be taken BEFORE placing the water heater back in service. Failure to do so could result in property damage, severe personal injury, or death.

B. Thermostat Adjustment and ECO Reset
There are two thermostats on dual element heaters. If temperature adjustment is necessary, TURN OFF POWER TO HEATER, remove black access cover and insulation. The thermostat protective cover SHOULD NOT be removed. Set temperature indicator to desired temperature. Replace insulation and the black access cover. Turn on power to the heater.

DANGER
Failure to disconnect the power from the water heater before attempting to adjust or reset the thermostat(s) will result in property damage, severe personal injury, or death.

IF YOU NEED TO ADJUST THERMOSTAT(S) OR RESET THE ECO (RED

Step #9 – If the water heater is operating properly and the water temperature is satisfactory, adjustment is complete.

WARNING
Risk of scald injury increases as you increase water temperature.

Failure to replace insulation or access cover could result in property damage, severe personal injury, or death.

C. Heating Element Replacement Procedure

WARNING
If heating elements need replacement, it is very important to use the same voltage, wattage, and construction. The element sheath must be incoloy and the hex plug must be made of stainless steel.

STEP #1 – Turn off power to the water heater. Use a phillips head screwdriver to remove wires connecting the element to the thermostat.
DANGER
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.
WARNING
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.
CAUTION
DO NOT replace heating element with a generic heating element. Only Westinghouse 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.
Step #3 – Remove the element with a 1 1/2” socket wrench or element tool.
Step #4 – Ensure thread and opening are completely free of debris. Use a nylon brush to clear away any debris.
Step #5 – Put a small amount of NSF approved lubricant and sealant on the O-Ring.
Step #6 – Screw the element clockwise into the tank, and tighten with the 1 1/2” socket wrench or element tool. Be sure O-ring seats properly.

NOTE: Repeat Steps 3 – 6 as Necessary for Multiple Elements Step #7 – 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.
WARNING
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 #8 – Pressure check the tank for leaks around element. If no leaks are found, connect wires from the element to the thermostat.
Step #9 – Turn power back on to the water heater.
CAUTION
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.

CAUTION
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.

WARNING
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 runs freely). Make certain that the heater is completely full of water before restoring power. Periodically (At least twice a year)
Check around the water heater and related plumbing for leaks. If the combination temperature and pressure relief valve discharges periodically, or water is leaking from around the heating elements, there may be a problem with your water system. DO NOT ATTEMPT TO REPAIR LEAKS YOURSELF! Contact a qualified service contractor for assistance.
Check the area around the water heater for flammable liquids or combustible materials. If any are found, remove from the area.

Vacation (Extended shut-off periods)
During extended mild or warm weather periods when hot water will not be in use, shut off the electric power to the tank. When hot water is needed again, restore power to the water heater.
During extended cold weather periods when hot water will not be in use and prone to freezing conditions, shut off electric power to the tank, close the supply line shut-off valve, open the drain valve and drain the water heater to a safe drainage location (as detailed previously). Once drained, close the drain valve. When hot water is needed again, restore the water supply to the tank. Once the tank is full, restore power.

WARNING
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.

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.

Ask the owner / user if there have been any issues with the water heater. Diagnose any heater issues and repair / replace parts as necessary.
Check the water heater and related plumbing for leaks. Repair any that are found.
Check the area around the water heater for flammable liquids or combustible materials. If any are found, remove from the area.
Check the heating elements while the heater is in operation. If the elements are hissing / singing excessively, they may need to be cleaned. Inspect the elements and clean if necessary.
Inspect the Temperature and Pressure (T&P) Relief Valve. See instructions below.
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.

WARNING
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.
