14.2.5 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.
14.2.6 Using the stop valve and service port
To handle the stop valve
Take the following guidelines into account:
▪ The gas and liquid stop valves are factory closed.
▪ Make sure to keep all stop valves open during operation.
▪ Do NOT apply excessive force to the stop valve. Doing so may
break the valve body.
To open the stop valve
1 Remove the stop valve cover.
2 Insert a hexagon wrench into the stop valve and turn the stop
valve counterclockwise.
3 When the stop valve cannot be turned any further, stop turning.
4 Install the stop valve cover.
Result: The valve is now open.
To fully open the Ø19.1~Ø25.4 mm stop valve, turn the hexagonal
wrench until a torque between 27 and 33N•m is achieved.
Inadequate torque may cause leakage of refrigerant and breakage of
the stop valve cap.
NOTICE
Pay attention that mentioned torque range is applicable for
opening Ø19.1~Ø25.4mm stop valves only.
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 stop valve cover
▪ The stop valve cover is sealed where indicated by the arrow. Do
NOT damage it.
▪ After handling the stop valve, tighten the stop valve cover
securely, and check for refrigerant leaks. For the tightening
torque, refer to the table below.
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.

14.2.7 To remove the spun pipes
WARNING
Any gas or oil remaining inside the stop valve may blow off
the spun piping.
If these instructions are NOT followed correctly it may
result in property damage or personal injury, which may be
serious depending on the circumstances.
Use the following procedure to remove the spun 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.
