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 unless supplied with factory installed freeze protection. 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.

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. User instructions for the

unit controls start on page 9.

Use Water Hammer Arrestors in applications with excess pipe lengths or fast acting

valves, neglecting to do so will damage the heater and void the warranty.

Use appropriate water conditioning to prevent water hardness in excess of 10 grains per

gallon. Also ensure that the pH level of the water is between 6.5 –7.5. Neglecting to do

so will damage the heater and void the warranty.

In accordance with NEC guideline, this water heater is designed for a contentious duty

cycle of 3 hours at 75% power output. Exceeding this rating could damage the heater

and void the warranty.

1) MOUNTING THE HEATER TO THE WALL

Your heater may or may not be installed in a NEMA 4/4X cabinet. Please follow the mounting instructions

as appropriate to your installation. Whenever possible, locate the heater as close to the point of hot water

use as possible. Time-to-temperature performance will improve the closer the heater is installed to the

point of use.

Make sure the brass fittings are at the bottom of the

heater and pointing “DOWN”. No other heater

orientation is permitted. Leave a service clearance of at

least 12” inches on the left and right sides of the heater.

SafeAdvantage: Install the heater with cabinet using the

supplied mounting feet following the instructions

provided with the cabinet. Be sure to use appropriately

rated fasteners to hold the cabinet/heater in place.

SpecAdvantage: Remove the cover by removing the

cover screws as indicated by the arrows (right) and

fasten the heater to the wall using the mounting holes

located at each corner of the back plate. Be sure to use

appropriately rated fasteners to hold the heater in place.
