Piping Installation When Piping is on the Right Side
See the Electrical System Installation section for information on how to con-
nect the communication / connection (power) wiring from the outdoor unit.
1. Align the center of the refrigerant piping and corresponding connection
as shown.
2. Place a couple of drops of refrigerant oil on outside of the flare before
assembling.
Do not add any contaminants. Tighten the flare nut
initially by hand.
3. Finish tightening the flare nut with a torque wrench until the wrench
clicks. Follow torque guidelines in the“Tightening the Flare Nuts”
procedure later in this section.

tightening follows the arrow on the wrench.
4. Bundle the refrigerant piping, drain hose, and communication / con-
nection (power) cable together. Ensure that the drain hose is located
at the bottom of the bundle.
If using a conduit for the power wiring / communications cable, see
below.
Positioning the drain hose at the top of the bundle can cause condensate to

1. Prop indoor unit away from wall bracket.
2. Guide communication / connection (power) cable insulation into the conduit.
Check local, state, and federal codes when choosing a conduit size.
For systems with wiring greater than 130 feet, see the “Communication / Connection (Power) Cable Specifications from Out-
door Unit to Indoor Unit” in the Electrical System Installation section for information.
3. Attach conduit using the liquidtight 3/4 inch elbow connector.
4. Reassemble the indoor unit properly onto the wall bracket.
5. If conduit is not used, see pages in this section for refrigerant piping, condensate drain, power wiring / communication
cable bundling information.
6. To protect the piping, condensate drain, and conduit from the elements, add a lineset cover from the indoor access hole to
the outdoor unit.
