2 Proper usage
This equipment may be used as intended and indicated only.
Valve core removal:
5/16 „-20 (1/4“FL) Valve core connection
(Fig. 1A)
1. Turn valve lever in the direction of flow so the shaft can go through the body.
2. Connect the valve core to the serviceport of the system.
3. Push the shaft towards the service port. Slowly and carefully rotate the shaft left until the tip
of the shaft engages the body of the valve core and remove it with ca. 4 turn out.
4.
If the valve core is correctly removed, the shaft is automatically pushed outward by the
pressure in the system. If it does not travel outward, either there is no pressure in the system
or the valve core was not removed. This will allow removing the valve core without loosing
the pressure in the system.
Failure to close valve could cause injury and would result in a loss of refrigerant!
Make sure the shaft connection nut does not start to turn as you are turning the shaft.
This could cause the shaft connection nut to loosen and refrigerant would leak out!
5. Loosen and remove the shaft connection nut from the valve body.
6. Remove the damaged valve core.
