Technical Information
Ƹ
• 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:
