1. Directions to bring out the pipes
The local interunit piping can be connected either forward or to the
sides (taken out through the bottom) as shown in the following figure.
When passing out through the bottom, use the knock hole in the bottom frame.
Precautions when knocking out knock holes
• Open knock hole in the base frame by drilling the 4 concave around
it with a 6 mm bit.
• Be sure to avoid damaging the casing
• After knocking out the holes, we recommend you remove any burrs
and paint them using the repair paint to prevent rusting.
• When passing electrical wiring through the knock holes, protect the
wiring with a conduit or bushings, making sure not to damage the
wiring.
2. Removing Pinch Piping
WARNING
Any gas or oil remaining inside the stop valve may blow off the pinch
piping.
Failure to observe the instructions in procedure below properly may
result in property damage or personal injury, which may be serious
depending on the circumstances.
Use the following procedure to remove the pinched piping:
1. Remove the valve cover and make sure that the stop valves are
fully closed.

3. Recover gas and oil from the pinched piping by using a recovery
unit.
CAUTION
Do not vent gases into the atmosphere.
4. When all gas and oil is recovered from the pinched piping discon-
nect the charge hose and close the service ports.
5. Cut off the lower part of the gas and liquid stop valve pipes along
the black line. Use an appropriate tool (e.g. a pipe cutter, a pair of
nippers)
WARNING
Never remove the pinched piping by brazing.
Any gas or oil remaining inside the stop valve may blow off the pinched
piping.
6. Wait until all oil is dripped out before continuing with the connection
of the field piping in case the recovery was not complete.
