Read and understand these instructions thoroughly before attempting the installation or service of this water
heater. This heater must be used to heat water only and be in a location where it is not subject to freezing
temperatures. If a water softener is used, the softener must be well-maintained and in good working order.
Any maintenance issues with a water softener could be detrimental to the operation or longevity of your
Eemax tankless water heater. The manufacturer is not liable for any damages resulting from improper
installation or misuse. The warranty of this water heater will depend upon the proper installation according
to these instructions. Refer to the warranty card packaged with this heater.
This installation must conform to the latest requirements of the National Electrical Code and all applicable
state and local codes. This information is available through your local authorities. You must understand and
comply with these requirements before beginning this installation. Eemax recommends your heater be
installed by a licensed plumber and electrician. User instructions for the unit controls start on page 6.
This unit is not required by UL 499 to have a Temperature and Pressure relief valve (T&P). You should check
