Drain Joint Installation
Before bolting the outdoor unit in place, install the drain
joint at the bottom of the unit. (See Fig. 6.11)
Fit the rubber seal on the end of the drain joint that
will connect to the outdoor unit.
Insert the drain joint into the hole in the base pan of
the unit.
Rotate the drain joint 90° until it clicks inUP place
facing the front of the unit.
Connect a drain hose extension (not included) tothe
drain joint to redirect water from the unit during
heating mode.
NOTE: Make sure the water drains to a safe location
where it will not cause water damage or a slipping
hazard.

Notes Pn Drilling BHole Jn UIFWall
You must drill a hole in the wall for the refrigerant piping
and the signal cable that will connect the indoor and
outdoor units.
Determine the location of the wall hole based on the
location of the outdoor unit.
Using a 65mm (2.5JO) 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 cuff in the hole. This
XJMMprotect the edges of the hole and will help
seal itwhen you finish the installation process.
NOTE:The minimum distance between the outdoor
unit and UIFwalls described in the installation guide
does not apply to airtight rooms. Be suSe to keep the
unit unobstructed in at least two of the three
directions (M, N, P) (See Fig. 6.10)
CAUTION
7. CONNECT THE DRAIN PIPE
Install the indoor unit's drain pipe
The outlet has a PTI screw bread. Use sealing materials and
a pipe sheath (fitting) when connecting the PVC pipes.
Drainage test
Ensure that the drainpipe is unhindered.
In a newly built house, this test should be
performed before the ceiling is paved.
The drain pipe and the connections of the indoor unit must be
heat insulated or they will condense dew.
A hard PVC binder must be used for pipe connection. Make
sure there is no leakage.
Do not impose pressure on the side of the indoor unit pipes.
When the declivity of the downward drain pipe is greater than
1/100, prevent winding.
When pulled out transversely, the total length of the drain pipe
must not exceed 20 m. If a pipe is unusually long, install a prop
stand to prevent winding.
Refer to Fig. 7-1 for the installation of the pipes.
