in.(mm)
1 Position of refrigerant and drain piping
• The drain pipe can be cut midway to meet the on-site conditions.
A (Total length of flexible hose)
B Liquid pipe
C Gas pipe
D Drain hose
2 Determine the position of the knockout holes on the unit body.
s Cut the knockout holes using a saw blade or an adequate knife.
Take care not to damage other parts of the unit.
• Remove the corner box and drill a knockout hole. If a hole is made without remov-
ing the box, the drain hose could be damaged.
E Left-side piping
F Lower piping
G Right-side piping
H Knockout hole for left-side piping
I Corner box
J Knockout hole for lower piping
K Through hole for the remote controller's cable
L Knockout hole for right-side piping

2 Determine the position of the knockout holes on the unit body. (Fig. 4-6)
F For left-side piping
G For lower-side piping
H For right-side piping
• Make the knockout holes using a saw blade or an adequate knife.
Caution:
The side panel must be removed before drilling a knockout hole in it.
If a hole is made with the side panel in place, the refrigerant pipe within the unit
could be damaged.
