BEFORE ATTEMPTING ANY INSTALLATION OR SERVICE OF THIS
HEATER, MAKE SURE THE ELECTRICAL POWER IS DISCONNECTED.
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN
SERIOUS INJURY, DEATH AND/OR PROPERTY DAMAGE.
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.
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
with local codes to find out if one is required in your area. If it is, it must be installed in the outlet hot water
pipe between the heater and the isolation valve.
This heater features a user friendly digital interface for ease of operation. Information is displayed through
a 16 character alpha numeric LCD and is controlled by 4 simple push buttons. The unit features silent
operation and internal diagnostics. The desired temperature can easily be set or altered as necessary. Once
the desired temperature is achieved, the control can be locked to avoid tampering.

E0: Excessive water flow detected
Corrective action: Using the OUTLET BALL VALVE, slowly reduce water flow until
the desired temperature is achieved. The temperature is proportional to the flow through the
heater; the lower the flow, the higher the temperature and vice versa.
Keep the INLET BALL VALVE fully “OPEN”. NEVER RESTRICT THE WATER
FLOW USING THE INLET VALVE.
E1: Inlet temperature too hot to generate heat
FAULT CODES:
F0: Thermistor out of range
