CAUTION
This tank, as all tanks, will eventually leak. Do not install without adequate drainage provisions where water flow will cause damage. Note: normal condensation from a tank may appear to be a leaking tank.
The tank will work better if you keep the hot water runs short. You will also get hot water faster and with less heat loss.
The illustration shows the correct valves and fittings that you will need to install the tank. Threaded (3/4”) water connections are supplied through the tank top.
WATER PIPING
This tank is design certified to be used with a potable water system. When connecting water piping with solder joints use only lead free solder.
WARNING
HOTTER WATER CAN SCALD: Water heating tanks are intended to produce hot water. Water heated to a temperature which will satisfy clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirmed, or physically handicapped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, some type of tempering device, such as a mixing valve, should be used at the hot water taps used by these people or at the tank.
WARNING
This tank shall not be connected to any heating systems or component(s) previously used with a
If this tank is also used for space heating applications, all piping and components connected to the tank shall be suitable for use with potable water.
This appliance has been design certified as a solar booster tank complying with Standards for Safety - UL174. The particular application of this appliance described (above paragraph) may be subject to review and approval by local code officials.
WARNING
Toxic chemicals such as used for treatment of boilers or non- potable water heating appliances shall never be introduced into a potable water space heating system.
WARNING
When the system requires water at temperatures higher than required for other uses, a means such as a mixing valve shall be installed to temper the water for those uses in order to reduce scald hazard potential. Mixing valves are available at plumbing supply or hardware stores. Follow manufacturer’s instructions for installation of these valves.

1.Buy the fittings that you need to connect the pipes. Remember that you have to connect both the hot and cold water pipes.
2.Apply a light covering of pipe joint compound to each outside thread before making connection.
3.Connect the cold water supply pipe to the cold water inlet of your tank as follows:
a.Look at the top cover of the tank. The hot and cold connections are marked there.
b.A
c.If using copper tubing, solder tubing to an adapter BEFORE you attach the adapter to the cold water inlet. DO NOT solder the cold water supply pipe directly to the cold water inlet connection. It might harm the dip tube.
d.The cold water supply line must have a
4.Use a union to connect the hot water supply pipe to the tank’s hot water outlet.
CAUTION
Operating an empty or partially filled tank will result in damage to the tank.
If a tank is installed in a closed water system; such as one having a back flow preventer, check valve or water meter with check valve in the cold water supply line, means shall be provided to control thermal expansion. Contact the water supplier or local plumbing contractor on how to control this situation.
WARNING
INSTALLATION IN RESIDENTIAL GARAGES: The tank must be located and/or protected so it is not subject to physical damage by a moving vehicle.
FILLING THE GEOTHERMAL STORAGE
TANK WITH WATER
1.Close the tank drain valve. The drain valve is on the lower front of the tank.
2.Open the cold water supply to the tank. NOTE: THIS VALVE MUST BE LEFT OPEN WHEN THE TANK IS IN USE.
