FIGURE 6
ROTATING CIRCUIT BREAKER
• Remove the indoor coil.
• Rotate the circuit breaker(s) (if in the horizontal right position) 180° (see instructions for
rotating breaker(s) that follow).
IMPORTANT: To comply with certification agencies and the National Electric Code,
units with circuit breaker(s) on vertical units must have circuit breakers installed so that
the breaker switch "on" position and marking is up and, "off" position and marking is
down.
- To turn breaker(s): Rotate one breaker pair (circuit) at a time starting with the one on the
right. Loosen both lugs on the load side of the 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 white plastic tab with hole away from breaker until
breaker releases from mounting opening (see Figure 6).
- 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 insula-
tion 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 white tab with hole away from breaker while setting that
side of breaker into opening. When breaker is in place, release tab, locking circuit break-
er 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.
WARNING
The RXHB-17, RXHB-21, or RXHB-24 combustible floor base is required when
certain units are applied downflow on combustible flooring. Failure to use the
base can cause a fire resulting in property damage, personal injury or death.
See clearances for units requiring a combustible floor base. See the accessory
section in this manual for combustible floor base RXHB-.
