INSTALLER / CONSUMER RESPONSIBILITIES

GENERAL

The Eemax “Three Phase Thermostatic DI” water heater is specifically designed to take in

cold or pre-heated De-ionized water and heat it to temperatures suitable for commercial
washing, sluicing or processing up to a maximum temperature of 180 F (82 deg. C). To
obtain optimum performance and energy savings, 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 will be damaged by excessive heat, do not solder

any pipes that are in contact with the heater.
Also ensure pipes are clear of installation debris before fitting the heater, otherwise the flow

switches could jam in the “on” position. The unit must be connected to its own individual electric

circuit protected by a suitably rated four pole breaker. The maximum voltage which can be
applied across any heating module is 277 volts.

WARNING

Improper installation, adjustment, alteration, service or maintenance can cause DEATH,
SERIOUS BODILY INJURY OR PROPERTY DAMAGE. Refer to this manual for
assistance or consult the local electric utility for further information.

The unit is supplied with compression pipe fittings suitable for direct coupling to standard

1/2 “ piping. There is no need for additional screwed fittings.

WARNING

Failure to ground the system may result in death or serious injury.

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.

5) The heater should be fixed to the wall using screws in the four mounting holes at each corner
of the backplate.

6) The unit should be installed in the plumbing system in such a way that there is no tendency
for the unit to be starved of water: for example: by an excessive draw-off of cold water just
before the unit. Also do not fit an unrestricted hot water draw-off point below the heater as
this will tend to empty the heater by siphoning.

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.
