To close the stop valve
1 Remove the stop valve cover.
2 Insert a hexagon wrench into the stop valve and turn the stop
valve clockwise.
3 When the stop valve cannot be turned any further, stop turning.
4 Install the stop valve cover.
Result: The valve is now closed.
To handle the service port
▪ Always use a charge hose equipped with a valve depressor pin,
since the service port is a Schrader type valve.
▪ After handling the service port, make sure to tighten the service
port cover securely. For the tightening torque, refer to the table
below.
▪ Check for refrigerant leaks after tightening the service port cover.

NOTICE
Precautions when making knockout holes:
▪ Avoid damaging the casing.
▪ After making the knockout holes, we recommend you
remove the burrs and paint the edges and areas
around the edges using repair paint to prevent rusting.
▪ When passing electrical wiring through the knockout
holes, wrap the wiring with protective tape to prevent
damage.
15.2.3 To protect against contamination
Seal the piping and wiring intake holes using sealing material (field
supply), otherwise the capacity of the unit will drop and small
animals may enter the machine.
15.2.4 To remove the pinched pipes
WARNING
Any gas or oil remaining inside the stop valve may blow off
the pinched 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 Make sure that the stop valves are fully closed.
2 Connect the vacuuming/recovery unit through a manifold to the
service port of all stop valves.

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,
disconnect the charge hose and close the service ports.
5 Cut off the lower part of the liquid-, gas-, and high pressure/low
pressure gas stop valve pipes along the black line. Use an
appropriate tool (e.g. a pipe cutter).
