(1) The refrigerant piping can be installed in four directions
(front, right, bottom or rear side) as shown in Figure 2.1.
Make a knockout-hole in the front side pipe cover or bottom
base to pass the pipe through the hole. After removing the
pipe cover from the unit, punch out the holes following the
guide line with a screwdriver and a hammer.
Then, deburr the holes and attach insulation (Field-supplied)
for protection of cables and pipes.
(a) Front and Right Side Piping Work
Select the correct knockout size depending on
the size of liquid and gas piping, power wiring, or
communication wiring.
The liquid or gas piping can be connected from “A”
part.
NOTES:
•
Protect cables and pipes from the edges of the
cover with insulations, etc. (Field-supplied).
•
“B” part is for communication cable.
But conduit hole is recommended. (refer to
Section 2.15.2 “Electrical Wiring Method”)
(b) Bottom Side Piping Work
After removing bottom of the knockout-hole, perform
piping.
NOTE:
Prevent the cables from coming into direct contact with
the piping work.
(c) Rear Side Piping Work
After removing the rear side piping cover, punch out “C”
hole along the guide line.
NOTES:
•
Protect cables and pipes from the edges of the cover
with insulations, etc. (Field-supplied).
•
“D” part is for communication cable.
But conduit hole is recommended.

NOTICE
For the right side and rear side piping work, secure enough space for the piping.
(2) Be sure to attach the piping cover to prevent rain water from entering the unit. Completely seal the
penetration parts of the pipes with field-supplied insulation in order to prevent rain water from entering
the conduit.
To make it easier to attach the piping cover, cut the lower side guide line of the piping cover.
(3) Use a pipe bender or an elbow (Field-supplied) for bending work while connecting pipes.
