Using a Conduit
1. Remove the rubber stopper on the indoor unit. Pass the power
wiring / communications cable through the conduit, the conduit
mounting plate, and to / through the control panel of the indoor
unit.
2. Tighten the conduit and the conduit mounting plate together.
3. Connect the power wiring / communications cable to the indoor
unit terminal block.
4. Screw the conduit mounting plate to the indoor unit.
• If the distance between the outdoor unit and indoor unit is greater
than 131 feet, connect the power wiring and communications
cable separately (i.e., a conduit cannot be used).
• For systems with wiring greater than 130 feet, see the "Commu-
nication / Connection (Power) Cable Specifications from Outdoor
Unit to Indoor Unit" earlier in this section for information.
