Refrigerant Piping

Drill a hole (65mm or 2-9/16 inches in diameter) in the spot indicated in the illustration below.

The location of the hole is different depending on which side of the unit the pipe is taken out.

For piping, see connecting the refrigerant pipe.

Allow adequate space around the pipe of the indoor unit for easier connection.
The suggested shortest pipe length is 2.5m or 98 5/16 inches. This is to avoid noise and vibration from the outdoor
unit.
Mechanical noise and vibration may occur depending on how the unit is installed and the environment in which it is
used.
Boring A Wall Hole and Installing the Wall Embedded Pipe
For walls containing metal studs or metal wall, be sure to use a wall embedded pipe and wall cover in the feed-
through hole.
Be sure to seal all the gaps around the pipes with caulking material to prevent water leakage.

Bore a feed-through hole of (65mm or 2-9/16 inches in diameter) in the wall in such a manner that it has a
downward slope toward the outside.

Insert a wall pipe into the hole.

Insert a wall cover into wall pipe.

After completing refrigerant piping, wiring, and drain piping, seal pipe hole gap with putty.
