• Choose position of piping hole according to the direction of

the outlet pipe. The position of the piping hole should be
just slightly lower than the wall-mounted frame. (Shown in
figure #1).

• Open pipe hole with diameter of

2 1/6” on selected outlet

pipe position. For smooth drainage, pitch the pipe hole on
wall slightly downward to the outdoor side with a gradient of
5-10O – (Shown in Figure #2).



Note:

• Attend to dust prevention by taking safety measure while

drilling.

• Plastic expansion screw set not included.

3. Outlet Pipe

• Pipe can be led out in the direction of right, rear right, left or

rear left – (Shown in Figure #3 below).

• When selecting leading out pipe (from left or right), cut out

corresponding hole on bottom (Shown in Figures 4 below).

4. Indoor Unit Pipe Connect

• Aim pipe to the corresponding bellmouth (Shown in Figure

#5 below).

• Pre-tighten union nut by hand.
• Use following torque table as reference below. Use double

wrench technique on union nut and pipe joint. Tighten the
union nut with torque wrench (Shown in Figure #6).

• Use insulation tape to wrap indoor pipe and joint of

connection pipe (Shown in Figure #7 below).

Refer to the following table for wrench moment of force:

5. Install Drain Hose

• Connect drain hose to outlet pipe of indoor unit. (Shown in

Figure #8 below).

• Bind the joint with tape (Shown in Figure #9 below).



Note:

• Prevent condensation by adding insulation to indoor

drain hose. (Shown in Figure #10 below).

• Plastic expansion screw set not included.

5. Connect the Pipe of Indoor Unit

(1) Aim the pipe joint at the corresponding bellmouth.(As show
in Fig.5)
(2) Pretightening the union nut with hand.
(3) Adjust the torque force by referring to the following sheet.
Place the open-end wrench on the pipe joint and place the
torque wrench on the union nut. Tighten the union nut with
torque wrench.(As show in Fig.6)
(4) Wrap the indoor pipe and joint of connection pipe with
insulating pipe, and then wrap it with tape.(As show in Fig.7)

6. Install Drain Hose

(1) Connect the drain hose to the outlet pipe of indoor unit.(As
show in Fig.8)
(2) Bind the joint with tape.(As show in Fig.9)

4. Outlet Pipe

(1) The pipe can be led out in the direction of right, rear right,
left or rear left.(As show in Fig.3)

(2) When selecting leading out the pipe from left or right, please
cut off the corresponding hole on the bottom case.(As show in
Fig.4)

(2) Open a piping hole with the diameter of Φ2 3/16(Φ2 3/4)
inch on the selected outlet pipe position.In order to drain
smoothly, slant the piping hole on the wall slightly downward to
the outdoor side with the gradient of 5-10°.(As show in Fig.2)
