ROTATING CIRCUIT BREAKER
- 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.
• RXHB combustible floor base is used for all unit sizes. Unit must be centered on com-
bustible base in the width dimension (14
on the combustible floor base.)
DRIP LOOP: When installing the unit in down-flow or horizontal-right positions, make
sure that the wires coming from the motor form a proper drip loop. This allows water to
cascade off the lowest point of the wiring before it enters the motor head. This may
require cutting the wire tie and installing a new wire tie to form this loop.
WARNING
The RXHB-17, RXHB-21 or RXHB-24 combustible floor base is required
when some units with electric heat 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 com-
bustible floor base RXHB.
• Rotate unit into the downflow position, with the coil compartment on top and the blower
compartment on bottom.
• The set of coil rails must be moved for vertical down-flow and horizontal right applica-
tion. Remove the coil rail from the factory configuration (6 screws in all). Fastener clear-
ance holes will need to be drilled in the cabinet sides (proper hole locations are marked
with "dimples" for this purpose). Note that the shorter (no notch) coil rail must be mount-
ed on the left-hand side to provide clearance for the drain pan condensate connection
boss.
• Reinstall the indoor coil 180° from original position. Ensure the retaining channel is fully
engaged with the coil rail. (See Figure 6, Detail A.)
• Secondary drain pan kits RXBM- (or equivalent) are required when the unit is config-
ured for the horizontal position over a finished ceiling and/or living space. (See Section
14.0: Accessories - Kits - Parts.)
IMPORTANT: Units cannot be installed horizontally laying on or suspended from the
back of the unit.
