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.

Before fi lling the solar water heater with water, the pump
station storage tank loop must be connected to the water
heater. See "Filling The Storage Tank Loop" section of the
manual.
The solar water heater is equipped with top and side pump
station water loop connections. Cap or plug the connections
that are not used in your application.
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 and solar loop air vent 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 OR IN THE PUMP
STATION STORAGE TANK LOOP THE HEATING
ELEMENT WILL BURN OUT IMMEDIATELY.
4. Check all the new water piping for leaks. Fix as needed.
