GENERAL

The Eemax “Three Phase Thermostatic” water heater is specifically designed to take in
cold or pre-heated  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 three pole breaker. The maximum voltage which can be
applied across any heating module is 208 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 rings and nuts suitable for direct coupling to standard
1/2 “ ( 5/8 “ outside diameter ) copper or plastic piping. There is no need for additional screwed
fittings and under no circumstances use a blow  torch on pipe which is connected to the heater
(serious damage to the electronic flow switch will result). Do not use pipe dope or Teflon tape.

WARNING

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