Caution
Please do not use the hot water in the
heater for drinking or similar purposes.
To guarantee effectiveness, do not feed
water to the heater several times within
one day in case of insufficient sunlight
exposure.
The source of the energy for the water
heater is solar energy, so it may be
incapable of being used normally under
cloudy, rainy and snowy weather
conditions due to the failure to reach
desired water temperature because of
insufficient sunlight exposure.
Caution
Warning
Warning
Warning
The glass vacuum tube shall not be
exposed for a long period without water
inside after installation to avoid the
shortening of the service life. If it cannot be
used immediately, it shall be covered.
Make sure of the smooth ventilation of the
air pipe. It is strictly prohibited to block the
outlet of the air pipe to avoid the collapse of
the water tank under suction.
Water shall be fed in early morning or at
night when the sunlight is insufficient. The
water feeding after sunlight exposure of the
glass vacuum tube will cause an explosion
of the pipe.
-Suggestions-
The water heater is non-pressurized, gravity-fed water heater relying on the height
difference of the water tank and point of use to supply hot water with the outgoing wate
r
pressure in direct proportion to the height. An additional pressurizer may be required.
Do not touch glass vacuum tube, pipes and
valves for supplying hot water during use to
avoid being burned.
Please feel the water temperature by hand
before use to make sure of proper water
temperature while in use

Frame assembly
Please see the related paper in the frame package for the diagram of the frame and
packing list.
Frame fastness
1. For horizontal water heaters, it is recommended to fix the feet of the heater onto the
foot foundation with embedded iron parts or make a concrete brick with expansion
bolts and then fix the feet of the heater to the expansion bolts.
2. Adjust the height of the frame by the hard waterproof cushion to keep the horizontal
tank and each foot evenly weighted.
Notice:
1. Make sure that the feet all closely contact the supporting floor without foot suspension to
avoid damage of the product due to frame deformation.
2. Please use the steel wire to firmly fasten the tank and frame if in a location where typhoons
frequently occur.
3. The water heater shall be stably and firmly installed to avoid severe damage or accident
due to harsh weather conditions.
Tank installation
1. Unpack the tank, remove the nuts and cushions fixed on the bolts on both ends of the tank.
2. Insert the bolts at the bottom of the tank into the long hole in the tank support of the frame,
apply the cushions and nuts.
3. Remove the sensor wound around the tank and install it onto the sensor hole on the tank.
Non-welding pipe ends
1. Pipe fittings are connected with the
pipe by a non-welding method.
2. During installation, use a wrench to
fasten the tank pipe end. Do not rotate
the tank pipe ends and do not apply
any force along the axial direction of
the fittings to avoid damage of the seal
ring.
3. When installing the overflow pipe, use
a wrench to fasten the overflow pipe
end of the tank, screw off the plastic
cap and connect the PEX pipe by
means of internal threads. Check
whether the seal ring of the overflow
pipe is in good condition before
installation.
Notice:
1. Rip off the protection film after installation. by Do not use a sharp tool.
2. The heater is assembled by means of bolt connections and nut fasteners. Tighten the nuts
after the unit assembly is finished.
3. When assembling the water tank, keep the center line of the vacuum tube connection
holes parallel with the diagonal post of the frame.
4. The inlet and outlet of the water tank can be also used as the drain.

Installation of vacuum tubes
1. Keep the tubes out of the sunlight before assembling the tubes to avoid being burned.
2. Place the air seal ring around the vacuum tubes (Figure A);
3. Insert the tubes into the seal ring with even pressure and a twisting motion. The resultant
force direction shall be consistent with the axial direction of the vacuum tubes;
4. Place the tubes into the tail support of the frame (Figure B) and then fix the tube onto the
tail base (Figure C);
5. Insert the tube into the seal ring at the depth of around 1cm, push the air seal ring to the
water tank hole for sealing (Figure D);
6. While assembling, install one tube on each end of the heater tank respectively first, so that
the heater tank and frame are positioned as a whole.

Notice:
1. Check whether the seal rings in tank holes are sufficiently installed and whether the
sealing location is clean and free from foreign matters and damage.
2. Place the bevel of the air seal ring downwards, and then put it onto the open end of the
tube with a clearance of around 10cm from pipe end. Make the pipe end wet before
insertion for easy assembly.
Installation of electric heater and Operation instructions
Wiring of electric heater
1. Unscrew the four screws on the terminal box cap, take out the cap and remove the
bonding clamps.
2. Put the power cables of 3X1.0mm2 across the seal ring of the bushing. Connect wires
according to the wiring map of the electric heater. Link the brown or red power cable onto
the “L” location identified as a live wire, yellow or green wire onto the identified as the
grounding wire, and the blue wire onto the “N” location identified as a neutral wire.
Afterwards, fix the power cables by bonding clamps and fastening the cap by screws.
Instructions for usage
1. Use proper sockets compatible with the plugs. Do not plug in or unplug the electric heater
frequently to avoid danger due to poor contact and burnt plugs or sockets caused by
damage of plugs and sockets
2. Please unplug the water heater before use to avoid electric shock.

Diagram of pipeline installation
Precautions on pipeline installation
1. Any alteration to the structure of the solar water heater may cause problems in use.
2. There are five ways to connect the water pipe to the room: flue, vent hole, through-hole in
the wall, pipe well for solar pipes and embedded sleeves, wherein the former three types
are commonly used. Before installation, the installation staff will consult the entry form and
installation location of the pipe in a comprehensive way and in consideration of your
convenience. A slope in the through-wall must be ensured during pipeline layout, and
sealing shall be guaranteed to prevent the entry of rain or odors.
3. Keep the smoothness of the air pipe to prevent the blockage of impurities, which may lead
to collapse and deformation of the water tank under suction when using water.
4. To avoid the return of water in the tank, a non-return valve shall be installed at the joint of
the water upward/downward pipes and the tap water.
5. The installation project should be confirmed by our professional service personnel when
installing several sets of the series of the products.

Operation instructions
1) Keep the mixing valve (for hot water)
and the mixing valve (for cold water)
closed before using water.
2) Open the mixing valve (for hot water) to
let water spray from the nozzle while
using water, and open the mixing valve
(for cold water) to regulate the water
temperature if the water is too hot.
3) Confirm that the manual valve and
mixing valves are all off after using
water.
Improper operation of the water
heater may lead to serious burns.
When using the heater, do not make
the water outlet of the nozzle aim at
the body, mix the cold and hot water
before use.
