This solar water heater shall not be connected to any heating systems or component(s) previously used with a non-potable water heating appliance.

If this solar water heater is also used for space heating applications, all piping and components connected to the solar water heater shall be suitable for use with potable water.

This appliance has been design certified as a solar water heater complying with Standards for Safety - UL174 for the U.S. and can/csa-c22.2 No 110 F379.1 and F379.2 for Canada. The particular application of this appliance described (above paragraph) may be subject to review and approval by local code officials.

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.

Figure 3

The solar water heater 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 solar water heater. Threaded (3/4”) water connections are supplied through the tank top.

Figure 4

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 solar water heater as follows:

a.Look at the top cover of the solar water heater. The hot and cold connections are marked there.

b.A non-metallic dip tube is supplied to carry cold water from the tank top to the bottom. Be sure that it is in the cold water inlet.

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 shut-off valve and union.

4.Use a union to connect the hot water supply pipe to the solar water heater’s hot water outlet.

Operating an empty or partially filled solar water heater will result in damage to the tank.

If a solar water heater 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.

INSTALLATION IN RESIDENTIAL GARAGES

The solar water heater must be located and/or protected so it is not subject to physical damage by a moving vehicle.

FILLING THE SOLAR WATER

HEATER WITH WATER

1.Close the solar water heater drain valve. The drain valve is on the lower front of the solar water heater.

2.Open the cold water supply to the solar water heater.

NOTE: THIS VALVE MUST BE LEFT OPEN WHEN THE SOLAR WATER HEATER IS IN USE.

3.Fill the solar water heater until a constant flow of water runs out an opened hot water faucet. This will let out air in the solar water heater and the piping. Close the faucet after all air has been purged and the water comes out with constant flow.. You must not turn the electricity on until the solar water heater is full of water. IF ANY AIR IS LEFT IN THE TOP OF THE SOLAR WATER HEATER, THE TOP HEATING ELEMENT WILL BURN OUT IMMEDIATELY.

4.Check all the new water piping for leaks. Fix as needed.

WIRING OF ELEMENT

Determine voltage and wattage from the rating plate attached to the solar water heater. All external wiring, connection, and overcurrent protective devices must be provided and installed in accordance with the latest edition of the National Electrical Code, local codes, and local utility requirements. The solar water heater must be electrically “grounded” by the installer. A green ground screw has been provided on the solar water heater’s junction box.

The grounding electrode conductor shall be of copper, aluminum, or copperclad aluminum. The material shall be resistant to corrosion, and shall be of one continuous length without a splice or joint.

Rigid metal conduit, intermediate metal conduit, or electrical metallic tubing may be used for the grounding means if conduit or tubing is terminated in fittings approved for grounding.
