NOTE: The minimum distance between the 
outdoor unit and walls described in the 
installation guide does not apply to airtight 
rooms. Be sure to keep the unit unobstructed 
in at least two of the three directions (M, N, P) 
(See Fig. 5.10)

Notes On Drilling Hole In Wall
You must drill a hole in the wall for the  
refrigerant piping, and the signal cable that will 
connect the indoor and outdoor units.  
1. Determine the location of the wall hole 
based on the location of the outdoor unit.  
2. Using a 65-mm (2.5”) core drill, drill a hole 
in the wall.  
NOTE: When drilling the wall hole, make 
sure to avoid wires, plumbing, and other 
sensitive components. 
3. Place the protective wall cu in the hole. 
This protects the edges of the hole and will 
help seal it when you nish the installation 
process.

Drain Joint Installation
If the drain joint comes with a rubber seal
(see Fig. 5.12 - A ), do the following:
1. Fit the rubber seal on the end of the drain joint 
that will connect to the outdoor unit.
2. Insert the drain joint into the hole in the base 
pan of the unit.
3. Rotate the drain joint 90° until it clicks in place 
facing the front of the unit.
4. Connect a drain hose extension (not included) 
to the drain joint to redirect water from the 
unit during heating mode.
If the drain joint doesn’t come with a rubber 
seal (see Fig. 5.12 - B ), do the following:  
1. Insert the drain joint into the hole in the base 
pan of the unit. The drain joint will click in 
place.
2. Connect a drain hose extension (not included) 
to the drain joint to redirect water from the 
unit during heating mode.
