Behaviors that

Directions that
must be noted.
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 water pressure in
direct proportion to the height. An additional pressurizer may be required.
Please clean the glass vacuum tubes before the winter comes. Keep their surface clean to
maintain heat collection efficiency.
where it's very cold in the winter, we recommend you select our optional solar
energy heater controller with anti-freeze function.
In the area
Warning! Improper operation of the following may lead to personal injury or even death!
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
Personnel other than professional
maintenance staff are prohibited
from repairing, maintenance,
dismantling or altering the water
heater without authorization.
Caution! Improper operation of the following may lead to personal injury or even death or property loss!
- -Suggestions
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.
The water heater is equipped with a
special venting pipe and overflow pipe.
To ensure normal operation, \never refit
or plug their outlets. Otherwise the water
tank will shrink.
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.
The
temperature of the hot water delivered
may not satisfy your requi rement. If there
is no electric heating as an auxiliary
energy source, it may be unable to be
used normally.
Water shall be fed in early morning or at
night when the sunlight is insufficient.

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 glass vacuum tubes can withstand
a low temperature of -70 when they
are not filled with water. When the
auxiliary heating device is not to be used,
on continuous cloudy days in winter or
when the tubes are covered by snow, be
sure to keep the water tank full of water
and replace the cold water in the tank
frequently (every 2 days). Otherwise the
water retained in the tank will cause the
vacuum tubes to break.
When the heater with auxiliary electric
heating function is used, ensure the
auxiliary electric heater and electric
heating accompanying strap are in OFF
state.

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.
Please see the related paper in the frame package for the diagram of the frame and
packing list.
1.Unpacking the tank, rip off the protection film.Uninstall the nut and cushion.
2.Place tank onto tank bracket cradle,inserting protruding bolts into holes,fasten with nuts.
1.Pipe fitting is connected to water pipe with
asolderless connection.
2.Overflow pipe and water inlet pipe both use
solderless structure. To install, use a wrench to
secure the water tank pipe head. In ordertoavoid
damaging the seals, do not rotate water tank pipe
head and do not apply force along the axial direction
of the pipe.
3.When installing the water inlet and outlet pipe,first
use a wrench to secure the water tankpipe head,
then unscrew the plastic cap and use inner ratchet
teeth to directly connect tothe PEX pipe. Before
installation, check that the gasket ring of the water
inlet and outlet pipe is intact.
Notice:
1.Rip off the protection film after installationto avoid the destroy of the tank,and please
do not use the sharp tool.
2.Leave nuts loose since some adjustment may be necessary after fitting tubes.
3.When assembling the water tank, keep the center line of the vacuum tube connecting
holes parallel with the diagonal pillar of bracket.
4.The inlet and outlet of the water tank can be also used as the drain.
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.

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 instructions

Diagram of pipeline installation
The diagram subjectto GV150REMB isfor
reference only.
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. Do not install a valve in the overflow
pipeline to ensure that the flood signal can be sent out rapidly and accurately.
5. 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.
6. The installation project should be confirmed by our professional service personnel when
installing several sets of the series of the products.
Connection of water supply pipes when the solar
water heater coexists with other water heaters
Please install another non-return valve
on the cold and hot water pipes
respectively if the solar heater coexists
with other water heaters so as to avoid
accidents caused by water returned to
the solar water tank through hot water
pipe due to high pressure in the tanks.
