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, 3 wire cable (2 wire plus
ground) of the appropriate size suitable for up to 75 degree C and protected by the correctly rated
circuit breaker. Refer to the chart on page 7.
FAILURE TO GROUND THE SYSTEM MAY RESULT IN SERIOUS INJURY, DEATH
AND/OR PROPERTY DAMAGE.
1) Power cable entry to the heater should be made
through one of the “knock-out” holes located on the
back plate or top/bottom ends of the unit. Use the
appropriate strain relief fitting.
2) The power leads are to be secured to the L1 and
L2 or L and N connectors on the terminal block or
relay. The ground lead is to be secured to the GND
connector on the block or the green ground wire
with the wire nut.
