DANGER! WATER TEMPERATURE SAFETY
SETTING
Safety is our pri mary goal when selecting
the water temperature. Any temperature
above 120°F can cause seri ous scal di n g or
death. Energy conservation is a factor to
be considered when selecting the water
temperature. Setting the water heater’s
thermostat to a lower setting will allow a
higher flow rate and use less energy.

INTRODUCTION
SuperGreen Tankless hot water heaters do not store water like a conventional tank-type
water heater. It contains multiple high powered quartz heating tube elements that are
capable of heating water “on-demand” and continuously as needed , so you wi ll never h ave
to worry about running out of hot water again.
The unit’s working principle and designs are simple. When the power is turned on, the
microprocess or will check t he temperature sensor and curr ent leakage sens or, if there ar e
no errors, the hot water generator is ready to work.
The performance of the products listed are dependent on incoming water temp, water flow
rate, and set temperature of the thermostat. In order for it to function properly it must be
matched by location, application, and unit size. As it requires no venting, all units can be
installed literally anywhere that is convenient for the owner.
This product should be installed indoors only. An outdoor installation is permitted as long as
it is mounted in a suitable enclosure that protects it from all-weather elements including
freezing. Freezing of the unit may result in permanent damage and will void the warranty.
Unit Operation:
When you open the hot water valve, the flow sensor activates at a minimum water flow. The
flow sensor sends the information to the temperature controller to begin modulating the
heating elements to heat the water as it passes through the quartz heating tubes and to
maximize efficiency.
If the wat er fl ow rat e exce eds th e m axi mu m h ea ti ng capacity of the unit, the unit will reach
a maximum achievable tempe rature based on f low rate and un it size. When a red uction in
the excessive flow rate is made, the unit will achieve the set point temperature.
When the fixture is closed, the demand stops, the flow sensor sends information to the
controller to turn off the power to the quartz heating elements. The unit remains in it
standby mode until the demand for the hot water is needed.
Unit Freezing:
In case of fr eezing, pl ease wait for th e complete defrosting of the unit before using. Verify
this by running water through it before turning on the power. Activating unit while still
frozen will damage the heaters internal components and void the warranty.
Maintenance:
This unit requires no maintenance. To extend unit service life, it is recommended to use an
inlet pre filter, check and clean it periodically. This is an additional part from the internal
screen included with the unit. Do not attempt to open the case to make adjustments,
repairs, or for any reason. Opening of unit will void all warranties and could result in serious
injury or property damage.
Included Parts List:
• Electric water heater
• Water (adjust) valve
• Wall Mount bracket
• Screws

INTERFACE
When you open the hot w ater valve , the flow se nsor activa tes at a minimum
water flow. The flow sensor sends the information to the temperature
controller to be gin modulating the heating elements to heat the water as it
passes through the quartz heating tubes and to maximize efficiency.
If the water flow rate excee ds the maximum he ati ng ca pac i ty o f the unit , the
unit will reach a maximum achievable temperature based on flow rate and
unit size. When a reduction in the e xcessive flow rate i s made, the unit w ill
achieve the set point temperature.
When the fixture is closed, the demand stops, the flow sensor sends
information to the controller to turn off the power to the quartz heating
elements. The unit r emains in it standby mo de until the demand for the hot
water is needed.
