GENERAL To obtain optimum performance and energy savings from your Eemax heater, the unit should be located as near as possible to the point of use. The unit must only be installed in a vertical position with the inlet and outlet at the bottom. The power is activated by individual electronic flow switches located in each of the three heating modules. These modules will be damaged by excessive heat; do not solder any pipes that are in contact with the heater.
PAGE 4
MOUNTING THE UNIT 1) The unit should be mounted as close to the point of use as possible. 2) This unit must only be mounted in the vertical position with the water fittings located at the bottom of the unit. Mounting other than in the vertical position WILL cause element burn out. 3) The cold water inlet is on the right hand side and the hot water outlet is on the left hand side. Under NO circumstances can these be reversed. 4) Leave a minimum of 8” above the unit for easy replacement of the elements.
PAGE 5
PLUMBING HOOK-UP 1) The unit is supplied with ½ “ compression fittings. DO NOT USE PIPE DOPE AND DO NOT SOLDER PIPE TO THE INLET OR OUTLET. 2) 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 manifold. 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.

ELECTRICAL HOOK-UP WARNING HAZARD OF ELECTRICAL SHOCK! BEFORE BEGINNING ANY WORK ON THE INSTALLATION, MAKE SURE THE ELECTRICAL SUPPLY TO THE HEATER IS TURNED “OFF”. FAILURE TO DO THIS COULD RESULT IN DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. WARNING WATER HEATERS EQUIPPED FOR ONE VOLTAGE ONLY: CHECK THE RATING PLATE ON THE FRONT OF THE UNIT. DO NOT USE THIS WATER HEATER WITH ANY VOLTAGE OTHER THAN THE ONE SHOWN ON THE MODEL RATING PLATE.
PAGE 7
COMMISSIONING YOUR HEATER 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 premature failure of the heating element will occur. To do this open all hot water fixtures one at a time for several minutes until the water flow is continuous and free from “gulping” and from visible air pockets. 1) With inlet and outlet BALL VALVES fully open, turn on a hot water outlet. 2) Run for 3 minutes.
PAGE 8
TROUBLESHOOTING SYMPTOM: NO HEAT - INDICATOR LIGHT OFF 1) ELECTRIC SUPPLY IS OFF Turn on the main circuit breaker. 2) NO OR LOW WATER FLOW Ensure that the minimum flow rate to turn on your heater is met, for this figure refer to page 2 of this manual. Also check that the inlet filter screen is clear from any debris. 3) WATER CONNECTIONS ARE REVERSED Cold water inlet = right side, hot water outlet = left side.
