SAFETY PRECAUTIONS

Have the installer show you the location of the circuit breaker and how to shut it off if necessary. Turn off the circuit breaker if the water heater has been subjected to overheating, fire, flood, physical damage or if the ECO fails to shut off.

• Read this manual entirely before installing or operating the water heater.
• Use this appliance only for its intended purpose as described in this Use and Care Manual.
• Be sure your appliance is properly installed in accordance with local codes and the provided installation instructions.
• DO NOT attempt to repair or replace any part of your water heater unless it is specifically recommended in this manual. All other servicing should be referred to a qualified technician.

Installing the water heater

The location chosen for the water heater must take into consideration the following:
Local Installation Regulations
This water heater must be installed in accordance with these instructions, local codes, utility codes, utility company requirements or, in the absence of local codes, the latest edition of the National Electrical Code. It is available from some local libraries or can be purchased from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269 as booklet ANSI/NFPA 70.

NOTICE: DO NOT install the water heater in attics where the temperature may exceed 150°F (66°C).

Location

• Locate the water heater in a clean dry area as near as practical to the area of greatest heated water demand. Long uninsulated hot water lines can waste energy and water.
• Place the water heater in such a manner that the upper electronic control and the lower access panels can be removed to permit inspection and servicing such as removal of elements or checking controls.
• The water heater and water lines should be protected from freezing temperatures.
• DO NOT install the water heater in outdoor, unprotected areas.
• Make certain the floor underneath the water heater is strong enough to sufficiently support the weight of the water heater once it is filled with water.

CAUTION: The water heater should not be located in an area where leakage of the tank or connections will result in damage to the area adjacent to it or to lower floors of the structure. Where such areas cannot be avoided, it is recommended that a suitable catch pan, adequately drained, be installed under the water heater.

NOTICE: Auxiliary catch pan MUST conform to local codes.
Catch Pan Kits are available from the store where the water heater was purchased, or any water heater distributor.

Inspect Shipment
Inspect the water heater for possible damage. Check the markings on the rating plate of the water heater to be certain the power supply corresponds to the water heater requirements.

Thermal Expansion

• Determine if a check valve exists in the inlet water line. Check with your local water utility. It may have been installed in the cold water line as a separate back flow preventer, or it may be part of a pressure reducing valve, water meter or water softener. A check valve located in the cold water inlet line can cause what is referred to as a “closed water system”. A cold water inlet line with no check valve or back flow prevention device is referred to as an “open” water system.
• As water is heated, it expands in volume and creates an increase in the 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 water heater flows back into the city main where the pressure is easily dissipated.
• A “closed water system”, however, prevents the expanding water from flowing back into the main supply line, and the result of “thermal expansion” can create a rapid and dangerous pressure increase in the water heater and system piping. This rapid pressure increase can quickly reach the safety setting of the relief valve, causing it to operate during each heating cycle. Thermal expansion, and the resulting rapid and repeated expansion and contraction of components in the water heater and piping system can cause premature failure of the relief valve, and possibly the heater itself. Replacing the relief valve will not correct the problem!
• The suggested method of controlling thermal expansion is to install an expansion tank in the cold water line between the water heater and the check valve (refer to the illustration below). The expansion tank is designed with an air cushion built in that compresses as the system pressure increases, thereby relieving the over pressure condition and eliminating the repeated operation of the relief valve. Other methods of controlling thermal expansion are also available. Contact your installing contractor, water supplier or plumbing inspector for additional information regarding this subject.

NOTICE: DO NOT apply heat to the HOT or COLD water connections. If sweat connections are used, sweat tubing to adapter before fitting adapter to the water connections on heater. Any heat applied to the water supply fittings will permanently damage the dip tube and/or heat traps.
NOTICE: This electric water heater is not intended to be used with Eemax or similar water temperature boosting products.

Water Supply Connections
Refer to the illustration below for suggested typical installation. The installation of unions or flexible copper connectors is recommended on the hot and cold water connections so that the water heater may be easily disconnected for servicing if necessary. The HOT and COLD water connections are clearly marked and are 3/4″ NPT on all models. Install a shut-off valve in the cold water line near the water heater.

Typical Installation

A new combination temperature and pressure relief valve, complying with the Standard for Relief Valves for Hot Water Supply Systems, ANSI Z21.22/CSA 4.4, is factory installed and must remain in the opening provided and marked for the purpose on the water heater. No valve of any type should be installed between the relief valve and the tank.

WARNING: The pressure rating of the relief valve must not exceed 150 PSI, the maximum working pressure of the water heater as marked on the rating plate.

Relief Valve

• The BTUH rating of the relief valve must not be less than the input rating of the water heater as indicated on the rating label located on the front of the heater (1 watt=3.412 BTUH).
• Connect the outlet of the relief valve to a suitable open drain so that the discharge water cannot contact live electrical parts or persons and to eliminate potential water damage.
• Piping used should be of a type approved for hot water distribution. The discharge line must be no smaller than the outlet of the valve and must pitch downward from the valve to allow complete drainage (by gravity) of the relief valve and discharge line. The end of the discharge line should not be threaded or concealed and should be protected from freezing. No valve of any type, restriction or reducer coupling should be installed in the discharge line.

WARNING: The tank must be full of water before heater is turned on. The water heater warranty does not cover damage or failure resulting from operation with an empty or partially empty tank.

To Fill the Water Heater

• Make certain the drain valve is completely closed.
• Open the shut-off valve in the cold water supply line.
• Open each hot water faucet slowly to allow the air to vent from the water heater and piping.
• A steady flow of water from the hot water faucet(s) indicates a full water heater.

Condensation

• Condensation can form on the tank when it is first filled with water. Condensation might also occur with a heavy water draw and very cold inlet water temperature.
• This condition is not unusual, and will disappear after the water becomes heated. If, however, the condensation continues, examine the piping and fittings for possible leaks.

CAUTION: The presence of water in the piping and water heater does not provide sufficient conduction for a ground. Non-metallic piping, dielectric unions, flexible connectors etc. can cause the water heater to be electrically isolated.

Electrical Connections

• A separate branch circuit with copper conductors, overcurrent protective device and suitable disconnecting means must be provided by a qualified electrician.
• All wiring must conform to local codes or latest edition of National Electrical Code ANSI/NFPA 70.
• The water heater is completely wired to the junction box inside jacket at the top front of the water heater. An opening for 1/2″ or 3/4″ electrical fitting is provided for field wiring connections.
• The voltage requirements and wattage load for the water heater are specified on the rating plate on the front of the water heater.

NOTE: Should this heater not be involved in a Demand Response Program, the EcoPort (CTA-2045) connections shown above will not affect the functionality or performance of the water heater.

The branch circuit wiring should include either:

1. Metallic conduit or metallic sheathed cable approved for use as a grounding conductor and installed with fittings approved for the purpose.
2. Non-metallic sheathed cable, metallic conduit or metallic sheathed cable not approved for use as a ground conductor shall include a separate conductor for grounding. It should be attached to the ground terminals of the water heater and the electrical distribution box.

NOTICE: This guide recommends minimum branch circuit sizing and wire size based on National Electric Code.
Refer to wiring diagrams in this manual for field wiring connections.

WARNING: If local codes require external application of insulation blanket kits the manufacturer’s instructions included with the kit must be carefully followed.

Insulation Blankets

• Insulation blankets, available to the general public, are for external use on electric water heaters. While not available on all models, the purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. To meet standards and/or requirements by the

• National Appliance Energy Conservation Act, with respect to insulation and standby loss, an insulation blanket may be necessary for some models. If a insulation blanket was included with your water heater, then your water heater will require an insulation blanket installed to ensure compliance with energy efficiency requirements.

• The manufacturer’s warranty does not cover any damage or defect caused by installation, attachment or use of
  any type of energy saving or other unapproved devices (other than those authorized by the manufacturer) into, onto or in conjunction with the water heater. The use of unauthorized energy saving devices may shorten the life of the water heater and may endanger life and property.

• The manufacturer disclaims any responsibility for such loss or injury resulting from the use of such unauthorized devices.

CAUTION: If local codes require the application of an external insulation blanket to this water heater, 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 relocate them on the exterior of 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 pressure and temperature relief valve.
• Inspect the insulation blanket frequently.

WARNING: If the water heater has been subjected to flood, fire, or physical damage, turn off power and water to the water heater.
DO NOT operate the water heater again until it has been thoroughly checked by qualified service personnel.

Safety Controls
The water heater is equipped with a temperature sensor and temperature limiting control (ECO) that is located above the upper heating element in contact with the tank surface. If for any reason the water temperature becomes excessively high, the temperature limiting control (ECO) breaks the power circuit to the heating element. Once the control opens, it must be reset manually.CAUTION: The cause of the high temperature condition must be investigated by qualified service technician and corrective action must be taken before placing the water heater in service again.

To reset the temperature limiting control:

1. Turn off the power to the water heater.
2. Remove the user interface control and insulation.
3. Press the red RESET button located on power board and upper sensor assembly.
4. Replace the insulation and user interface control before turning on the power to the water heater.

Care and cleaning of the water heater

Draining the Water Heater

• CAUTION: Shut off power to the water heater before draining water.DANGER: Before manually operating the relief valve, make certain no one will be exposed to the hot water released by the valve. The water drained from the tank may be hot enough to present a scald hazard and should be directed to a suitable drain to prevent injury or damage.
• In order to drain the water heater, turn off the cold water supply. Open a hot water faucet or lift the handle on the relief valve to admit air to the tank.
• Attach a garden hose to the drain valve on the water heater and direct the stream of water to a drain. Open the valve.
• DANGER: Before manually operating the relief valve, make certain no one will be exposed to the danger of coming in contact with the hot water released by the valve. The water may be hot enough to create a scald hazard. The water should be released into a suitable drain to prevent injury or property damage.
• NOTICE: If the temperature and pressure relief valve on the hot water heater discharges periodically, this may be due to thermal expansion in a closed water system.
• Contact the water supplier or your plumbing contractor on how to correct this. DO NOT plug the relief valve outlet.

Routine Preventative Maintenance

• Properly maintained, your water heater will provide years of dependable trouble-free service.
• It is suggested that a routine preventive maintenance program be established and followed by the user.
• It is further recommended that a periodic inspection of the operating controls, heating element and wiring should be made by service personnel qualified in electric appliance repair.
• Most electrical appliances, even when new, make some sound when in operation. If the hissing or singing sound level increases excessively, the electric heating element may require cleaning. Contact a qualified installer or plumbing contract to inspect.
• At least once a year, lift and release the lever handle on the temperature pressure relief valve, located near the top of the water heater, to make certain the valve operates freely. Allow several gallons to flush through the discharge line to an open drain.
• A water heater’s tank can act as a setting basin for solids suspended in the water. It is therefore not uncommon for hard water deposits to accumulate in the bottom of the tank. It is suggested that a few quarts of water be drained from the water heater’s tank every month to clean the tank of these deposits.
• Rapid closing of faucets or solenoid valves in automatic water using appliances can cause a banging noise heard in a water pipe. Strategically located risers in the water pipe system or water hammer arresting devices can be used to minimize the problem.
• The anode rod should be removed from the water heater’s tank annually for inspection and replaced when more than 6″ of core wire is exposed at either end of the rod.
• Make sure the cold water supply is turned off before removing anode rod.

NOTICE: Refer to the Hydrogen Gas Caution in the Operating Instructions.

Extended Shut-Down

• If the water heater is to remain idle for an extended period of time, the power and water to the appliance should be turned off to conserve energy and prevent a build-up of dangerous hydrogen gas.
• The water heater and piping should be drained if they might be subjected to freezing temperatures.
• After a long shut-down period, the water heater’s operation and controls should be checked by qualified service personnel. Make certain the water heater is completely filled again before placing
  it in operation.

NOTICE: DO NOT remove the anode rod from the water heater’s tank, except for inspection and/or replacement, as operation with the anode rod removed will greatly shorten the life of the glass lined tank and will exclude warranty coverage.

Anode Rod

• This water heater is equipped with an anode rod designed to prolong the life of the glass lined tank. The anode rod is slowly consumed, thereby eliminating or minimizing corrosion of the glass lined tank.
• Water sometimes contains a high sulfate and/or mineral content and together with cathodic protection process can produce a hydrogen sulfide, or rotten egg odor in the heated water. Chlorination of the water supply should minimize the problem.
