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 3/4” NPT pipe connections. Under no circumstances use a blow

torch on pipe which is connected to the heater (serious damage to the electronic flow
switch will result). Carefully use Teflon tape, ensuring no debris enter the heater. Do not

use pipe dope.

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

FAILURE TO GROUND THE SYSTEM MAY RESULT IN DEATH OR SERIOUS INJURY.

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.

I. MOUNTING THE UNIT

1) The unit should be mounted as close to the point of use as possible. For example, directly
beneath the sink is ideal.

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.

2) This unit must only be mounted in a 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 and cause 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.
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 screws in the four mounting holes at each corner
of the backplate.
NOTE: The heater should be installed below the level of all hot water outlets serviced by this

heater.

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.
