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
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 water
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
