OPERATION PRINCIPLE How the Eemax Tankless Water Heater Works Operating the new Eemax tankless water heater is similar to using any traditional water heater system. However, it is very important that all of the set-up procedures and operating instructions are carefully read to ensure maximum performance and energy savings from the water heater. The Eemax tankless water heater does not store hot water like a conventional tank-type water heater.
MOUNTING THE HEATER TO THE WALL Please follow the mounting instructions as appropriate to your installation. Eemax recommends the heater be installed close to the point of use. CAUTION This heater must be installed in a location where it is not subject to freezing temperatures, unless supplied with factory installed freeze protection Make sure the brass fittings are at the bottom of the heater. No other heater orientation is permitted.
ELECTRICAL HOOKUP Eemax recommends your heater be installed or serviced by a licensed plumber and electrician. WARNING Before beginning any work on this installation, BE SURE THAT THE ELECTRICAL BREAKER IS “OFF” AND THAT ALL MOUNTING AND PLUMBING WORK HAS BEEN COMPLETED PER THESE INSTRUCTIONS. This heater must have its own independent circuit using insulated, UL listed wire conductors of the appropriate size suitable for up to 90° C and protected by the correctly rated circuit breaker.

MONITORING & PREVENTIVE MAINTENANCE Recommended routine instrument readings and operation checking: Please note the instrument readings are performed during water heater operation. No readings are required when the unit is not being used.
CONTROL FEATURES CAUTION BEFORE USING THIS CONTROL, make sure all prior installation steps have been properly completed, electrical power is on and water is present in the heater. Push Button Flow Chart 1) The SETPOINT TEMP or ACTUAL TEMP screen can be selected for display as the home screen. Either of these screens will remain on the display when the backlight timer expires. SETPOINT TEMP120F 2) There is a 5-minute time delay built into the control.
8) From the LOAD PCT screen, one press of the RIGHT button will shift the display to the FLOWRATE screen. This shows the rate of flow of water through the heater. LOAD PCT 0% PWR FLOWRATE ??? GPM 9) From the FLOWRATE screen, one press of the RIGHT button will shift the display to the UNITS screen. This shows the units of measure in either the ENGLISH or METRIC systems. ENGLISH units are degrees Fahrenheit and gallons per minute. METRIC units are degrees Celsius and liters per second.
12) FAULTS are communicated through the LCD display. The display will switch from the SETPOINT screen to the FAULT screen and back again every 3 seconds. FAULTS indicate an undesirable condition and will immediately shut down the operation of the heater. If faults are appearing on your heater call Eemax Technical Support for assistance.

Choose the location for the enclosure's electrical conduit connection(s) based on the requirements on page 49, "Electrical Supply Requirements". Drill and deburr enclosure conduit fitting holes in the protected enclosure. Mount the fittings. Determine appropriate route for the enclosure electrical and power alarm signal conduit Measure, cut and thread conduit, check conduit fit to ensure proper seating. Fully ream all conduit.
Set-up Procedure Helpful Hints “Safe" pressure, for purposes of this manual, is defined To test the vent's operation, gently prod the vent flapper as a minimum .25 inch (6.4 mm) of water column. open with a soft pointed object, (example: eraser end of a pencil) ensuring that the vent valve works freely. On Regulator may be in the locked position upon arrival. To vertically configured vents, this can be accomplished adjust regulator, pull handle to outward position. from within the protected enclosure.
Operating Sequence WARNING Do not exceed “Safe” pressure with the Enclosure Pressure Control Valve. Operators must follow step-by-step sequence of the Start-Up Instructions Nameplate on the Protection System. Class I Purging Operation With the protective gas supply connected, enclosure power deenergized and alarm system energized (if utilized). 1. 2. 3. 4. 5. 6. Carefully read Start-Up Instructions on system. Check operation of the Enclosure Protection Vent (EPV-3) opening it manually several times.

System Maintenance Regular Maintenance Drain the Protection System Filter (if utilized) frequently and clean system with non-solvent cleaning agents only. Long Term Maintenance Calibrate the enclosure pressure indicator to 0 inches by venting the purge pressure reference port and the protected enclosure to atmosphere and adjusting the calibration screw in the lower center portion of the indicator’s face.
Optional Enclosure Heater 1) Attach heat tape and foam insulation to all lengths of inlet and outlet water piping that are exposed to freezing temperature. We recommend a rating of -30 degrees F at 10 miles per hour wind. Connect the heat tape to an independent source of electrical power. CAUTION Failure to attached heat tape and insulation to exposed inlet and outlet pipes will void the warranty.
Optional GFCI The optional GFCI consist of (A) Control Module and (B) Current Transformer. This control module has a LCD display indicating real-time measurements. The GFCI module is preset from factory to trip at 3.0 A. Test and reset functions are carried out automatically every 24 hours. To manual test the GFCI, press the test button for a minimum of 1.5 seconds. To reset a tripped GFCI, cycle the power of the unit.
