Screw the Wöhler SC 660 tightly onto the ex-
•
ternal thread of the connection valve so that
the circuit is closed again.
Screw in the blue knurled screw until the
•
Schrader valve of the measuring nozzle is
open.
After the measurement, unscrew the blue
•
knurled screw again so that the valve of the
measuring connection closes again and no re-
frigerant escapes when the Wöhler connection
valve is dismantled.
