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.

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.

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.
