Installation and Best Layout Practices
DUCT (HIGH STATIC) INDOOR UNITS
Using a Conduit
1. Remove the rubber stopper on the indoor unit. Pass the power wiring / communica-
tions cable through the conduit, the conduit mounting plate, and to / through the
control panel of the indoor unit.
2. Connect the power wiring / communications cable to the indoor unit terminal block.
3. Screw the conduit mounting plate to the indoor unit.
4. Tighten the conduit and the conduit mounting plate together.
If the distance between the outdoor unit and indoor unit is greater than 131 feet, connect
