GENERAL INTRODUCTION
SUPERGREEN Tankless hot water generator IR-3000, 4000,
6000 and IR-8000 series are a new generation electric tankless hot
water generators. SUPERGREEN IR-series are the first electric
tankless hot water generators to utilize the patented
SUPERGREEN Logic to combine the efficiency of non-metallic
quartz heating elements together with the accuracy of a Fuzzy
Logic PID Temperature Controller to achieve temperatures within
+/-1° F. Our new hot water generators were designed for safety,
dependability, reliability and economy to provide maintenance-free
continuous hot water for many years, while being the most
environmentally friendly.
SUPERGREEN Tankless hot water generators 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.
SUPERGREEN Tankless IR-3000, 4000, 6000 and IR-8000 series
working principle and design are simple. When the power is turned
on, the microprocessor will check the temperature sensor and
current leakage sensor, if they are not errors, the hot water
generator is ready to work.
When you open the hot water valve, the flow sensor activates at a
minimum water flow of 0.5 GPM. The flow sensor sends the
information to the temperature controller to begin modulating the
heating elements to heat the water as it passed 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 (within
a few degrees of the set temperature). When a reduction in the
excessive hot water flow rate is made, the unit will achieve and
maintain 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. A convenience circuit
breaker is provided to manually turn ON/OFF the unit.

Symptom Probable cause Remedy
No hot water Electricity not on or
one of the supplies
has failed
Check electricity supply.
Plumbing crossover Test by turning cold water
supply off to the hot water
generator, then open hot
water at one of the outlet.
No water should flow, if
water is flowing then you
might have plumbing
crossover that needs to be
corrected for the unit to
operate properly.
Water flow rate is less
than required
minimum 0.5 GPM
Increase water flow rate.
The flow sensor is not
working
Turn off the power, open
the unit and verify the flow
sensor not obstructed by
debris.
Note: During normal
operation when water is
turned on, the 4 digits LED
on the circuit board inside
the hot water generator
should display the flow
rate.

VI. TROUBLESHOOTING GUIDE
II. PLUMBING CONNECTIONS
INLET AND OUTLET CONNECTIONS: The inlet and outlet
connections are clearly marked on the unit. They each have a 3/4”
NPT connector. The cold water inlet is on the right hand side and
the hot water outlet is on the left hand side. Under NO
circumstances can these be reversed, reverse cause the unit to be
inoperable.
ISOLATION VALVES: Install isolating valves (ball valve type) on
both inlet and outlet water line. This valve can be used to turn off
the water supply to the unit if it needs servicing or maintenance
purposes.
PRESSURE RELIEF VALVE: You should check the local codes to
find which type of PRV is required in your area. The use of one 3/4"
150 PSI pressure only relief valve must be installed on each hot
water generator on the hot water outlet before the outlet ball valve
with a drainage discharge tube installed in accordance of national
and local codes.
GATE VALVE: Must install at outlet, after Pressure Relief Valve to
calibrate the flow and hot water
FINAL MOUNTING AND PLUMBING INSTALLATION CHECKS:
1. Insure that the unit is securely fastened to a wall.
2. Check the system for water leaks at all the plumbing connections.
3. If a leak is present take corrective action and tighten all
connections as necessary.
4. After the unit has been plumbed, flush it with water to remove any
debris or loose particles.
5. Make sure that the unit is located in an area that is free from direct
contact with movable objects, such as doors, appliances and in
garage installations require proper mounting height and protection
from all motorized vehicles. Do not use unit as a means to support
piping.
6. Confirm that the proper wire size is used when installing the hot
water generator, as this may result in an unsafe electrical
condition.
7. Recommend that a drain pan is installed for attic or all other
installations within inside the conditioned living space to prevent
possible water damage.
8. Follow all installation clearances specified in this manual.
NOTICE: ALL MOUNTING AND PLUMBING MUST BE
COMPLETED PRIOR TO MAKING THE ELECTRICAL
CONNECTIONS.

ELECTRICAL SHOCK.
WARNING: THE UNIT MUST BE PROPERLY GROUNDED.
FAILURE TO GROUND THE SYSTEM MAY RESULT IN DEATH
OR SERIOUS INJURY.
REMOVE THE COVER: Remove the two (2) screws on both sides
of the unit and four (4) screws on the bottom of the unit and lift up
the front cover (carefully to avoid damage to the circuit breakers).

INSTALLING AND COMMISSIONING THE TANKLESS HOT
WATER GENERATOR:
I. MOUNTING THE UNIT
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.
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.
IV. COMMISSIONING YOUR ELECTRIC HOT WATER
GENERATOR
WARNING: OPEN HOT WATER FAUCET FOR A FEW
MINUTES UNTIL WATER FLOW IS CONTINUOUS AND ALL
AIR IS PURGED FROM WATER PIPES. THE UNIT COVER
MUST BE INSTALLED BEFORE THE CIRCUIT BREAKERS
ARE TURNED ON.
Turn ON the main circuit breakers to energize electrical power
to the unit.
Switch ON the built-in circuit breaker on the front of the unit.
Adjust the water temperature to the desired level using the key
on the temperature controller on the front cover of the unit.
(Factory default temperature setting @120°F)
To set temperature using the temperature controller:
Adjust temperature using UP/DOWN button.
1. Turn on hot water and wait 5-10 seconds until temperature
has stabilized.
2. Check the water temperature and make sure that it does not
feel too hot, and reduce if necessary.
3. The hot water generator is factory pre-set at 120°F. Raising
the temperature above 125°F is not according to the National
Plumbing Codes. For commercial or other heating applications
requires additional programming information from the factory
and may require the installation of a secondary safety device
or a tempering valve.
4. Your tankless hot water generator is now working in
AUTOMATIC OPERATION. When water flows through the
unit, the electric hot water generator will turn on to heat the
water to the set temperature. When the flow of water stops,
the electric hot water generator will shut off and remain on in
the standby mode.
V. MAINTENANCE
The SUPERGREEN tankless hot water generator requires no
maintenance other than to periodically check unit for leaks, and
clean any external brass ball valve Y- type filter as requires.
IMPORTANT NOTE: IF LEAKAGE OCCURRED DURING THE
OPERATIONS OF THE HOT WATER GENERATOR
Immediately, turn off the main breaker, shut off the hot water
generator inlet/outlet water valves and contact your professional
installation or service personnel for further support.
