GEOTHERMAL STORAGE T ANKS
INST ALLA TION • OPERA TION • MAINTENANCE
The storage tank is sold as a component part. It has been factory equipped with a booster element, and thermostat with high limit.
The tank is designed to store potable water within the limits listed on the rating plate and to supply domestic hot water up to the element’s heating capability.
If the tank leaks or the element fails to operate, all technical and warranty questions should be directed to the local dealer from whom the tank was purchased. If you are unsuccessful, please write to the company listed on the warranty sheet which came with the tank.
Instruction Manual
WARNING Improper installation, adjustment, alteration, service or maintenance can cause injury or property damage. Refer to this manual. For assistance or additional information consult a qualified installer , service agency or the local utility .
RATING PLATE
A rating plate identifying the manufacturer of the tank will be found above the drain valve. When referring to the tank, always have the information listed on the rating plate readily available.

INSULA TING JACKETS:
When installing an external insulation jacket on the tank:
• DO NOT cover the temperature-pressure relief valve.
• DO NOT cover the instruction manual. Keep it on the side of the water heater or nearby for future reference.
• DO obtain new warning and instruction labels from the manufacturer for placement on the blanket directly over the existing labels.
Failure to follow these instructions can result in serious personal injury or death.
THE MANUFACTURER OF THIS T ANK WILL NOT BE LIABLE FOR ANY DAMAGE DUE TO FAILURE T O FOLLOW THESE

TYPICAL INSTALLATION
Check all connections for leaks. Consult the local utility company to examine installation for propriety and safety.

INSTALLATION
WARNING
Never operate the electrical heating element without being certain the tank is completely filled with water . If any air is left in the top of the tank, the heating element will burn out.
LOCAL CODES
The installation of the tank must be in accordance with these instructions and all applicable local codes and electric utility requirements. In the absence of local codes, install in accordance with the latest edition of the National Electrical Code (NFPA-70).
TEMPERATURE-PRESSURE
RELIEF VALVE
WARNING
For protection against excessive pressures and temperatures in this water heater, install temperature-pressure protective equipment required by local codes, but not less than a combination temperature-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, the latest edition of ANSI Z21.22. This valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 lbs./sq. in.).
Install the temperature-pressure relief valve directly into the fitting of the water heater. Position the valve downward and provide tubing so that any discharge will exit only within 6 inches above, or at any distance below the structural floor. Be certain that no contact is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 15 feet, or use of more than two elbows can cause restriction and reduce the discharge capacity of the valve.
No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to discharge drain unless a 6” air gap is provided. To prevent bodily injury, hazard to life or damage to property, the relief valve must be allowed to discharge water in quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage.
The Discharge Pipe:
• Must not be smaller in size than the outlet pipe size of the valve, or have any reducing couplings or other restrictions.
• Must not be plugged or blocked.
• Must be of material listed for hot water distribution.
• Must be installed so as to allow complete drainage of both the temperature-pressure relief valve, and the discharge pipe.
• Must terminate at an adequate drain.
• Must not have any valve between the relief valve and tank.
When installing the temperature-pressure relief valve, use two or three turns of teflon tape or other suitable thread sealer around the threaded end of the valve.
FIGURE 2
WARNING
The temperature-pressure relief valve should be manually opened once a year. Caution should be taken to ensure that (1) no one is in front of or around the outlet of the temperature­pressure relief valve discharge line, and (2) the water manually discharged will not cause any bodily injury or property damage because the water may be extremely hot.
If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions, and replace the temperature-pressure relief valve with a new one.
WARNING
If the temperature-pressure relief valve on the appliance weeps this may be due to thermal expansion. The water supply serving this tank may have a check valve installed. Contact the water supplier or local plumbing contractor on how to control this situation. Do not plug the temperature­pressure relief valve.
LOCA TING THE GEOTHERMAL ST ORAGE T ANK
If you have a choice of where to install the tank, these ideas may help you decide.
1. Put the tank indoors as close as possible to where you use the most hot water. This tank is not intended for outdoor installation.
2. It is handy to have a floor drain, tub or sink nearby. That will make it easy to drain water from the tank. It is also a good place to end the drain line of the temperature-pressure relief (T & P) valve.
3. The tank or the pipes and the connections may, in time, leak. Put the tank in a place where a water leak will not damage anything.
4. You must not put the tank in an area where it might freeze. Y ou must turn off the electricity to the t ank before you drain it, to protect the heating elements.
5. Make sure that you are able to reach the drain valve and all access panels when the tank is in place. This will make it easy to service the tank.
6. The tank must be level before you begin the piping.
CAUTION
WA TER HEATERS EVENTUALLY LEAK. The installation of the
tank must be accomplished in such a manner that if the tank or any connections should leak, the flow of water will not cause damage to the area adjoining the water heater or to lower floors of the structure. When such locations can’t be avoided, a suitable drain pan should be installed under the tank. Such a pan should be no greater than 1 1/2 inches deep, have a minimum length and width of at least two inches greater than the tank dimensions and must be piped to an adequate drain.
