INSTALLATION
Indoor Unit Connections
Using a Conduit for Indoor Unit Wiring / Cable Installation
1. Indoor unit includes a conduit bracket that can be found in the accessory kit. Assemble the conduit and
bracket with a grommet and washer (field-supplied or included with the elbow connector).
2. Guide communication / connection (power) cable insulation into the conduit.
3. Attach the conduit / bracket assembly to the indoor unit using the screws found in the accessory kit.

4. To protect the piping, condensate drain, and conduit from the elements, add a lineset cover from the indoor access hole to the outdoor
unit.

Bundling
If a conduit or piping set cover is not used on the connection from the outdoor unit to the
interior, bundle both separately insulated refrigerant pipes, the drain hose, and outdoor
unit to indoor unit communication / connection (power) cable together with wide vinyl
tape.
1. Both piping must be fully and separately encased in insulation material: Overlap the
field installation piping insulation material and the indoor unit piping insulation mate-
rial.
2. Bind together the two pipes, using vinyl tape. Make sure there are no gaps during the
binding. Verify that any insulation material cutting lines are placed upward.
3. Bind together the two pipes, using narrow vinyl tape. Make sure there are no gaps
during the binding.
4. Continue to wrap the indoor unit pipe as connected to the outdoor connection pipe.
5. Using a wider vinyl tape, bundle the piping and drain hose together.
• Tape must be sufficient to cover the piping in order to fit into the rear piping housing
area at the back of the indoor units.
