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.
