Operational Instruction Manual
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.
Model: IR-3000, 4000, 6000, 8000 Electric Tankless Hot Water Generators Please read through the manual before installment and operation
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.
WARNING: THIS PRODUCT MUST BE INSTALLED AND SERVICED BY A LICENSED ELECTRICIAN AND PLUMBER, OR A PROFESSIONAL SERVICE TECHNICIAN AND/OR IN ACCORDANCE WITH ALL LOCAL CODE. IMPROPER INSTALLATION AND/OR OPERATION, OR INSTALLATION BY AN UNQUALIFIED PERSON CAN CAUSE PROPERTY DAMAGE, SERIOUS BODILY INJURY OR EVEN DEATH. GENERAL SAFETY RULES: This appliance must be properly grounded.
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.
