15.2 Connecting the refrigerant piping
15.2.1 Using the stop valve and service port
To handle the stop valve
Take the following guidelines into account:
▪ The gas, equalising and liquid stop valves are factory closed.
▪ Make sure to keep ONLY gas and liquid stop valves open during
operation. In case of multi outdoor unit system, also open
equalising stop valve.
▪ Do NOT apply excessive force to the stop valve. Doing so may
break the valve body.
To open the stop valve
1 Remove the dust cap.
2 Insert a hexagon wrench into the stop valve.
3 FULLY turn the stop valve counterclockwise and tighten until
the correct tightening torque value is achieved (see "Tightening
torques"[431]).
NOTICE
Stop valves need to be opened on torque specified in this
manual. It is not allowed to turn valve "a quarter turn" back
when opening it.
4 Install the dust cap.
Result: The valve is now open.
NOTICE
Reinstall dust cap to prevent aging of O-ring and risk of
leakage.
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.
