AERATOR SUPPLIED IS .5GPM/ 1.9LPM
To ensure the optimal temperature output and overall performance of your tankless water heater an aerator
supplied with heater should be installed.

PROPERLY SIZE YOUR AERATOR TO PREVENT SCALDING
7- GENERAL OPERATING INSTRUCTIONS
Operating your new tankless water heater is similar to using any traditional water heating system. However, it is
very important that you carefully read all of the setup procedures and operating instructions and tips to ensure
the maximum performance and energy savings from your new water heater. We recommend that all members
of the household read these General Operating Instructions.
How your new water heater works:
This tankless water heater differs from a conventional storage water heater as it does not store hot water, but
heats water as it flows through the heater.
The temperature of the hot water delivered by the heater depends on the wattage of the heating element,
temperature of the incoming cold water and the water flow rate through the water heater.
