GENERAL SAFETY
The “Eemax ProAdvantage” heater is specifically designed to take in cold or hot water and
heat it up to a maximum of 140F (60C). To obtain optimum performance and energy savings,
the unit should be located as near as possible to the point of use. The unit is supplied with
1/2” compression fittings.
THIS UNIT HAS ONE DEDICATED INDEPENDENT 120V, 208V,240V OR 277V
CIRCUIT. USE CORRECTLY RATED WIRESAND CIRCUIT BREAKERS.
U.L. 499, 18.4. THE RATING OF THE BRANCH-CIRCUIT OVERCURRENT
PROTECTIVE DEVICE SHALL BE 150% OF THE RATING OF THE PRODUCT.
DO NOT USE SPACE SAVING BREAKERS.
WARNING
IMPROPER INSTALLATION,ADJUSTMENT, ALTERATION, SERVICE, OR MAINTENANCE,
MAY CAUSE DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. REFER TO
THIS MANUAL FOR ASSISTANCE OR CONSULT THE LOCAL ELECTRIC UTILITY FOR
FURTHER INFORMATION.
FAILURE TO GROUND THE SYSTEM MAY RESULT IN DEATH OR SERIOUS INJURY.
WARNING
WARNING
WATER HEATERS ARE EQUIPPED FOR ONE VOLTAGE ONLY: THIS WATER HEATER IS
EQUIPPED FOR THE VOLTAGE DISPLAYED ON THE MODEL RATING PLATE. DO NOT
USE THIS WATER HEATER WITHANY OTHER VOLTAGE OTHER THAN THE ONE
SHOWN ON THE MODEL RATING PLATE. FAILURE TO COMPLY WITH THIS MAY RESULT
IN DEATH, SERIOUS BODILY INJURY, AND/OR PROPERTY DAMAGE. IF YOU HAVE ANY
QUESTIONS OR DOUBTS CONSULT EEMAX OR YOUR LOCAL ELECTRIC COMPANY.
WARNING
HAZARD OF ELECTRICAL SHOCK! BEFORE REMOVING THE COVER OR SERVICING THE
WATER HEATER, MAKE SURE ALL ELECTRICAL SOURCES TO THE WATER HEATERARE
TURNED “OFF”. FAILURE TO DO THIS MAY RESULT IN DEATH, SERIOUS BODILY INJURY,
OR PROPERTY DAMAGE.
NOTE: THIS UNIT HAS ONE DEDICATED INDEPENDENT ELECTRICAL POWER
CIRCUIT CONNECTION.

DISCONNECT THE POWER CIRCUIT BEFORE SERVICING.
DO NOT SOLDER PIPES WHILE THE UNIT IS INSTALLED
(serious damage to the electronic flow switch will result).

I. MOUNTING THE UNIT
1) The unit should be mounted as close to the point of use as possible.
Do not install the heater above a faucet or “point of use” because the siphoning effect may
drain the heater which can cause premature element burn out. If the unit must be installed at
a higher elevation, you must install spring loaded check valves on both the inlet and outlet of
the water heater.
2) This unit must only be mounted in a vertical position with the water fittings positioned at
the bottom of the unit. Mounting other than in the vertical position will cause element burn
out and permanent damage to the water heater.
3) The cold water inlet is on the right hand side and the hot water outlet is on the left hand side
as marked by the fittings of the unit. Under NO circumstances can these be reversed.
4) Leave a minimum of 8” above the unit for easy replacement of the element.
5) The heater should be fixed to the wall using all four mounting holes of the backplate. (Fig.1)
Use an appropriate fastener for the weight. For the unit to be mounted against hollow walls,
we suggest using steel wall anchors with the correct grip range, and #10-32 screws at a
minimum.
NOTE: The heater should be installed below the level of all hot water outlets serviced by this
heater. Otherwise install spring loaded check valves on both the inlet and outlet.
NOTE: PRESSURE AND TEMPERATURE RELIEF VALVE
These units are not required by UL to have a Pressure and Temperature Relief
Valve (PTRV). You should check with local codes to find out if one is required in your
area. If local codes require the use of a temperature and pressure relief valve it
should be installed on the outlet hot water pipe before the outlet ball valve.

II. PLUMBING HOOK-UP
1) The unit is supplied with ½” compression fittings (Figure 2a ).
2) DO NOT USE PIPE DOPEAND DO NOT SOLDER TO THE INLET OR OUTLET.
3) Take care to ensure that the pipes are correctly aligned with the inlet and outlet bosses
in order to avoid excessive stress on the heater body molding.
NOTE: When soldering pipe joints remove heater from the wall. Serious damage can occur
if any soldering is done while pipes are connected to the heater.
Run water through the supply pipe to remove all debris from the pipe before
connecting the heater. Failure to do so could cause damage to the flow switch.
4) Install isolating valves (full flow ball valve type) on both inlet and outlet pipes. This allows unit
to be isolated for maintenance purposes. (Fig. 2b)
5) When all plumbing is complete, fully check the system for water leaks at all the plumbing
connections. If any leaks are present take corrective action. Then fully open both inlet and
outlet BALL VALVES, run the hot water outlet fed by this heater for a minute or two, until the
water flow is continuous, free from “gulping” and from all visible air pockets.
NOTE:
ALL MOUNTING AND PLUMBING MUST BE COMPLETE BEFORE YOU
PROCEED WITH ELECTRICAL HOOK-UP.
TEST THE INSTALLATION FOR LEAKS BEFORE CONNECTING THE
ELECTRICAL SUPPLY.

III. ELECTRICAL HOOK-UP
WARNING
BEFORE DOING ANY WORK ON THE UNIT BE SURE THE
BREAKER IS “OFF” TO AVOID ANY DANGER OF SHOCK.
“Eemax ProAdvantage” heaters are manufactured to the following specifications:
The L1, L2, or N should be connected to the slots in the contactor marked L1 and L2.
(see Fig 2b). The ground lead must be connected to the stud marked GND.
GROUND MUST BE BROUGHT TO THE “GROUND” AT THE CIRCUIT BREAKER PANEL.
Use a dedicated circuit with appropriate wiring and circuit breaker configuration which is
dictated by the power requirements of the unit. (see Table 1 and Fig 3)

IMPORTANT
BEFORE SWITCHING “ON” THE POWER AT THE MAIN CIRCUIT BREAKER PANEL
MAKE SURE THAT THE HOT WATER CIRCUIT IS FREE OF AIR POCKETS OR ELSE
PREMATURE FAILURE OF THE ELEMENT WILL OCCUR. TO DO THIS OPEN ALL HOT
WATER OUTLETS ONE AT A TIME FOR A MINUTE OR TWO UNTIL THE WATER FLOW
IS CONTINUOUS AND FREE FROM “GULPING” AND FREE FROM VISIBLE AIR POCKETS.
1) Open fully both inlet and outlet valves at the heater. (see Fig 2b)
2) Open any hot water outlet in the system. If the outlet is a “single lever” mixer type turn to the
hottest position. Run for one minute to clear all the air from the system.
3) Slowly close OUTLET ball valve until the water flow from the faucet just starts to reduce.
NOTE: This process has two effects. One, any air in the system will be purged out. Two, the
heater unit will be pressurized up to the supply pressure. This will prevent the elements from
having air pockets when energized.
4) At this point you may energize the hot water heater. Once energized the Thermostatic control
touch pad display on the front cover will illuminate. This is where and when you will program
your desired temperature.(see Fig 4)
NOTE: Unit will display the programmed temperature, not the actual outlet temperature
IV COMMISSIONING YOUR HEATER

To trouble shoot the display board, shut off power to the unit. Press and hold all three buttons,
and re-energize the unit. If display board is working properly, the word “Yes” will display. If the
board has a fault it will display “No” and you should call technical support for a replacement.

TROUBLESHOOTING
SYMPTOM “A”: NO HEAT, INDICATOR LIGHT –OFF
1) ELECTRIC SUPPLY IS OFF
Ensure the breaker is properly connected to the contactor. (see Fig 2b)
Check the main circuit breaker and reset it to “on”. (see Fig 3)
2) NO OR LOW WATER FLOW
Ensure that the minimum flow rate to switch on your heater is met.
Minimum flow rate = 0.70 gallons per minute. Check that the inlet filter screen is clear from
any debris. This is located in the brass inlet boss. (see Fig 2a)
3) WATER CONNECTIONSARE REVERSED
Cold water inlet = right side, hot water outlet = left side.
4) ELEMENT BURNED OUT
TURN OFF THE MAIN CIRCUIT BREAKER!
Using an ohmmeter test the resistance of the heating element
across the two threaded termination rods on top of the element.
The resistance reading should be 4-15 ohms. If the resistance
is much greater than this value, call Eemax for a replacement element.
SYMPTOM “B”: LOW OR NO HEAT, INDICATOR LIGHT - ON
1) WATER FLOW TOO HIGH
Reduce the water flow by adjusting the outlet ball valve.
2) INCORRECT POWER SUPPLY
Make sure that the unit is connected to the voltage supply specified on the rating label on
the front cover of the unit.
3) ELEMENT BURNED OUT
TURN OFF THE MAIN CIRCUIT BREAKER!
Repeat the steps from paragraph 4 above.
