GENERAL SAFETY

The “Eemax Series Two” heater is specifically designed to take in cold water
and heat it to temperatures suitable for normal domestic usage up to a maximum of 140 F
(60 C). 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 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 while pipe is connected
to the heater (serious damage to the electronic flow switch will result).

Also, ensure that the pipes are clear of installation debris before fitting the heater.

THIS HEATER MUST HAVE TWO DEDICATED INDEPENDENT
CIRCUITS, USING CORRECTLY RATED WIRES AND CIRCUIT

BREAKERS.

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
