IMPORTANT
To comply with certification agencies and the National Electric Code for horizontal right
application, the circuit breaker(s) on field-installed electric heater kits must be re-installed per
procedure below so that the breaker switch "on" position and marking is up and, "off" position
and marking is down.
• To rotate breaker(s): Rotate one breaker set (circuit) at a time starting with the one on the
right. Loosen both lugs on the load side of the breaker. (Make sure that wires are identified and
are reinstalled into proper breaker).Wires are bundles with wire ties, one bundle going to the
right lug and one bundle going to the left lug.
• Using a screwdriver or pencil, lift blue plastic tab with hole away from breaker until breaker
releases from mounting opening.
• With breaker held in hand, rotate breaker so that "on" position is up, "off" position is down
with unit in planned vertical mounting position. insert right wire bundle into top right breaker
lug, ensuring all strands of all wires are inserted fully into lug, and no wire insulation is in lug.
• Tighten lug as tight as possible while holding circuit breaker. Check wires and make sure each
wire is secure and none are loose. Repeat for left wire bundle in left top circuit breaker lug.
• Replace breaker by inserting breaker mounting tab opposite white pull tab in opening, hook
mounting tab over edge in opening.
• With screwdriver or pencil, pull blue tab with hole away from breaker while setting that side
of breaker into opening. When breaker is in place, release tab, locking circuit breaker into
location in opening.
• Repeat above operation for remaining breaker(s) (if more than one is provided).
• Replace single point wiring jumper bar, if it is used, on line side of breaker and tighten
securely.
• Double check wires and lugs to make sure all are secure and tight. Check to make sure unit
wiring to circuit breaker load lugs match that shown on the unit wiring diagram.
When using the unit with electrical heater, the switch is used only for electrical heater on the
front of panel.
