SAFETY INFORMATION
IT IS IMPORTANT TO COMPLETELY READ AND UNDERSTAND THE
INSTALLATION PROCEDURES BEFORE CONTINUING THE
INSTALLATION.
FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN
PROPERTY DAMAGE, SERIOUS BODILY INJURY, OR DEATH.
THIS PRODUCT SHOULD BE INSTALLED BY A LICENSED ELECTRICIAN
AND PLUMBER IN ACCORDANCE WITH ALL NATIONAL, STATE, AND
LOCAL ELECTRICAL & PLUMBING CODES.

DANGER! WATER TEMPERATURE
SAFETY SETTING
Safety is our primary goal when
selecting the water temperature.
Any temperature above 120°F can
cause serious scalding 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.

User Manual.

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 will never have 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 microprocessor will check the temperature sensor and current
leakage sensor, if there are 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 water flow rate exceeds the maximum heating capacity of the unit, the
unit will reach a maximum achievable temperature based on flow rate and
unit size. When a reduction 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 freezing, please wait for the 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.

MOUNTING YOUR WATER HEATER
1. Leave a minimum of 6” to both sides and 12” on the top and bottom of
the unit for clearance and maintenance. A minimum clearance of 24" in
front of the unit must be provided for safe removal of the front cover, for
installation, advanced troubleshooting, and service if required.
2. Mount the electric hot water generator securely to the wall with six (6)
screws. The two (2) mounting brackets located at the top and bottom of
the unit with eyelet holes.
3. This unit must only be mounted in a vertical position with the electrical
and water fittings located at the bottom of the unit.
4. Avoid installing the hot water generator in a corrosive environment, as
this may cause damage to the electronic components.
5. Installation of the hot
water generator must be
in accordance with all
National and Local codes
having Jurisdiction and
installed by a Licensed
Contractor.

PLUMBING INSTALLATION
CAUTION: Breaker must remain off until installation is complete.
Step 1: Flush cold water line to clear any debris before connecting to unit.
Step 2: Install a shut off valve and pre filter (Not Supplied) to prevent any
particles entering the unit that may clog or damage the internal parts.
Step 3: Using flexible lines only, connect the Cold Water line to the water
heater inlet labeled with a blue ring. Connect furnished Water Valve to the
water heater outlet labeled with a red ring. Connect the HOT WATER outlet
line to the Water Valve. DO NOT Solder any fittings to unit. This will damage
internal sensors and components and void the warranty. Use flexible lines
and screw fittings only to unit. A TP valve is not required in most
jurisdictions. Verify your local codes accordingly and if required install on
outlet side only.
Step 4: Verify all fittings are tight and secure. Open hot water source and
allow water to run though the water heater for at least 1 to 2 minutes. This
will purge the air from the water lines and must be performed prior to
turning on the power at the unit. This is a Mandatory step to prevent
Damage to Heating Elements.
Verify all connections are free of leaks.

Step 1: Remove cover of the water heater carefully and locate the electrical
disconnect breaker on the bottom left hand corner facing the unit.
Step 2: Use the correct wire gauge that meets all NEC or country of
installation guidelines based on the size of the breakers used to feed the unit
and the length of the wire run. Then run the set of wires from the home’s
main panel to the tankless water heater. A separate ground conductor is
required. (See above chart for minimum wire size) This minimum wire size is
based on maximum of 50’ of length.
Step 3: Connect the wires to one two-pole breaker (see wiring diagram).
Use a green wire for the ground ONLY.
Step 4: Verify all connections are tight and secure. Verify the correct breaker
size. Verify the ground conductor size and connection per applicable codes.

IR-3000 – IR-8000 Wiring Diagram:

How to calibrate your hot water using water valve
1. Make sure all electrical wires and water pipes are properly installed.
Check the power requirement for each model. Before start up, check that all
connections are secure and fittings are tight. Confirm that all air has been
purged from the system.
2. Turn power on and verify the unit set temp (SV) is 105-110 degrees.
Open tub faucet. The water begins to heat and the current temperature is
shown in the display. Dial the Gate Valve on the Hot Side Only to calibrate
your hot water vs the flow rate. Ideally, you will gain a higher flow rate by
lowering the set temp as water moves through the water heaters quartz
elements faster. If hotter water is required, simply raise the set temp and/or
slow the water flow rate to meet your temperature needs.
3. Calibrate using Gate Valve (water valve) at hot outlet and choose a
desirable temperature by pressing the up or down buttons and adjusting the
gate valve until you have a comfortable water temperature and flow rate.
Never use the cold inlet valve to adjust flow. This will restrict water from
flowing in and cause damage to the heating elements.
4. Turn off water and unit is set.
