Water Chemistry Requirements

Chemical imbalance of the water supply may affect efficiency and cause severe damage to the appliance and associated equipment. Water quality must be professionally analyzed to determine whether it is necessary to treat the water. Various solutions are available to adjust water quality. Adverse water quality will affect the reliability of the system. In addition, operating temperatures above 135oF will accelerate the build-up of lime scale and possibly shorten appliance service life. Failure of an appliance due to lime scale build-up, low pH, or other chemical imbalance IS NOT covered by the warranty. The water must be potable, free of corrosive chemicals, sand, dirt, and other contaminates. It is up to the installer to ensure the water does not contain corrosive chemicals or elements that can damage the heat exchanger. Potable water is defined as drink able water supplied fromutility or well water in compliance with   maximum contaminant levels (40 CFR Part 143.3). If the water contains contaminants higher than outlined by the EPA, water treatment is recommended and additional, more frequent maintenance may be required. If you suspect that your water is contaminated in any way, discontinue use of the appliance and contact an authorized technician or licensed professional.

Water pH between 6.5 and 8.5

•  pH levels below 6.5 can cause an increase in the rate of corrosion. pH of 8.5 or higher can potentially cause lime scale build-up
•  Maintain water pH between 6.5 and 8.5. Check with litmus paper or have it chemically analyzed by a local water treatment company.
•  If the pH is not between 6.5 and 8.5, consult a local water treatment company for solutions.

Hardness less than 12 grains (200 mg/L)

•  Hardness levels above the required amounts can lead to limescale build-up throughout the system. Water below 5 grains/gallon (85 mg/L) may be over softened.
•  Consult local water treatment companies for unusually hard water areas (above the required amounts) or for other treatment solutions if water is being over softened (below 5grains/gallon [85 mg/L]).

Chloride concentration less than 100 ppm (mg/L)

•  Do not fill appliance or operate with water containing chlorides in excess of 100 ppm (mg/L).

•  Using chlorinated fresh water should be acceptable as levels are typically less than 5 ppm (mg/L).

•  Do not connect the appliance to directly heat swimming pool or spa water.
  Total Dissolved Solids (TDS) less than 500 ppm (mg/L)

•  Total dissolved solids are minerals, salts, metals, and charged particles that are dissolved in water.

• The greater the amounts of TDS present, the higher the corrosion potential due to increased conductivity in the water.

•  If using softened water to fill the appliance, it is still possible to have high TDS. This water can be corrosive. Consult local water treatment companies for other treatment solutions to reduce this affect.

NOTE: To promote appliance service life, it is strongly recommended to follow the maintenance procedures in this manual
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.

 Anode Rod

This water heater is equipped with an anode rod. Anode rods are sacrificial components that counteract water chemistry to minimize
or eliminate tank corrosion. The anode rod should be inspected at least annually and replaced as necessary to prolong tank life. Have the supply water quality professionally analyzed, as local water conditions will influence the duration for inspection and replacement of the anode rod. The use of a water softener may increase the speed of anode
consumption. More frequent inspection of the anode is needed when using softened or treated water. Water with high sulfate and/or mineral content can produce a rotten
egg odor in heated water. Consult a water treatment specialist for potential remedies.
NOTE :
Do not remove the anode rod from an operating water heater. Operating the water heater without the anode rod will shorten the life of the tank and VOID the warranty.
NOTE:
If anode rods are rapidly consumed water chemistry should be tested by a qualified technician. Corrective action should betaken to prevent the premature failure of the water heating system. Operating the water heater with fully consumed anode rods will shorten the life of the tank and VOID the warranty.
CAUTION
Hydrogen gas is produced in a hot water system served by this heater that has not been used for a long period of time (two [2]weeks or more). Hydrogen gas is extremely flammable. To reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system. When hydrogen is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. There should be no smoking or open flame near the faucet at the time it is open.

Piping

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.

1. 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 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.
2.  Connect the hot water line to the connection marked “HOT” on the top of the water heater.
3. Ensure the T&P Valve is installed in the opening provided near the top of the heater.
4.  Ensure the drain valve is installed in the opening provided near the

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 with in 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 there lief 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 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

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 inl et 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.

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.

Temperature and Pressure Relief Valve

For protection against excessive pressures and temperatures in this water heater, ensure temperature and pressure protective equipment is installed 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 / CSA4.4-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. The water heater ships with an installed T&P valve. DO NOT OPERATETHE WATER HEATER WITH THE T&P VALVE BLOCKED OR REMOVED! 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.

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 water way 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 THESE GUIDELINES COULD RESULT IN
  FAILURE OF RELIEF VALVE OPERATION, RESULTING IN POSSIBILITYOF 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 occurring 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 contract or 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 BUILDUPWHICH CAN RESULT IN PROPERTY DAMAGE, SERIOUSPERSONAL INJURY, OR Deerpath. Do not thread a cap or plug into the relief live or block relief valve outlet line under any circumstances! Explosion and property damage, serious injury, or death may result.

Scalding

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 to meet installation requirements.
•  Feel water before bathing or showering.
•  Use the mixing valve in accordance with the instruction provided by the manufacturer .Failure to 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 when ever using hot water to avoid scalding injury. Certain appliances such as dish washer sand automatic clothes washers may require increased water temperatures. By setting the thermostat onto his heater to obtain he increased water temperature required by these appliances you may create the potential for scald injury. To protect against injury, a mixing valve has been installed in the water heater. This valve will reduce point of used is charge temperatures by mixing cold and Hopwater in branch supplylines.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.

Warning
After install at Table ion, water heater outlet temperature MUST BE checked with a thermometer at a hot water outlet fixture.

• Finish installing the water heater. Ensure it is proper lypiped, powered, and full of water (purged of air).

• Power the water heater. Wait for the water heater to satisfy the thermostat set point and has finished heating.

•  Choose the hot water outlet fixture nearest to the water heater.

•  Open the outlet. Check the outlet temperature with a
  thermometer. NOTE: DO NOT check the outlet temperature with your hand.

•  Make a note of the temperature measured by the thermometer when it stops rising.
  NOTE: It may take some time for cooler water to clear the system.

•  Follow the instructions in this manual if thermostat or mixing valve need adjustment. Failure follow these instructions could result in property damage

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.
Applications
PIPING NOTES:

1. Minimum pipe size should match connection size. Upsize pipe accordingly if greater flow is required.
2. 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.
3. All circulators should have an integral flow check.
4. Drains and check valve between unit and storage tank will assist in purging air from system.
5. 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.
6. Mixing valve application is optional, but recommended to help prevent scalding.

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.

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

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. Use a flat head screwdriver to set temperature indicator to desired temperature. Replace insulation and the black access cover. Turn on power to the heater.

Prior to setting the valve, fill and purge the water heater and system. Ensure the system water valves are open. Power the water heater ON. Wait for the water heater to heat to the design temperature (set at the water heater thermostat). Only then proceed to adjusting the tank booster.

• STEP #1 – Open a hot water faucet in the system. Use a thermometer to measure the water temperature at the faucet. If the outlet water temperature needs to be adjusted, use a 3/16” Allen key to hold the mixing valve adjustment dial in place. Then use a 7/16” wrench to loosen the locking nut.

NOTE: Water must be flowing from a hot water faucet while adjusting the outlet temperature.

• STEP #2 – Use the wrench to support the locking nut and prevent it from rotating. Then turn the 3/16” Allen key clockwise to reduce the temperature, or counter-clockwise to increase the temperature. Measure the outlet water temperature at the hot water faucet. Adjust the valve as described until the desired temperature is reached.

• STEP #3 – After reaching the desired outlet temperature, use the 3/16” Allen key to hold the mixing valve adjustment dial in place. Then use a 7/16” wrench to tighten the locking nut. Make note of the set outlet temperature for future reference.
  

WARNING:
Risk of scald injury increases as you increase water temperature. Households with small children, disabled, or elderly persons may require a 120oF or lower temperature setting to prevent severe personal injury or death due to scalding.

Heating Element Replacement Procedure

WARNING:
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.

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.

• 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.
  

• 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.

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 #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.

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.
