Eemax requires an inlet Y-strainer be installed for
unit debris protection and warranty coverage.
Eemax also commends 2 unions, 2 full flow ball valves
and two drain plugs be installed for future
serviceability. These components are supplied by
others. (See photo to right.)
Run water through the cold water inlet pipe to purge
it of any debris before making final plumbing
connections to the heater.
3) ELECTRICAL HOOK-UP
BEFORE BEGINNING ANY WORK ON THIS INSTALLATION, BE SURE THAT THE
ELECTRICAL BREAKER IS “OFF” AND THAT ALL MOUNTING AND PLUMBING
WORK HAS BEEN COMPLETED PER THESE INSTRUCTIONS.
This heater must have its own independent circuit using insulated, UL listed wire conductors of the
appropriate size suitable for up to 75° C and protected by the correctly rated circuit breaker.
See chart on next page.
Before starting any electrical work VERIFY there is no
power at the heater before proceeding !
The power conductors are to be secured to the L1, L2
and L3 connectors on the terminal block. The ground
is to be secured to the GND connector to the right of
the terminal block.
FAILURE TO GROUND THE SYSTEM MAY RESULT IN SERIOUS INJURY,
DEATH AND/OR PROPERTY DAMAGE.
