3 Installation and operation
Valve core installation:
5/16 „-20 (1/4“FL) Valve core connection (Fig. 1A)
1. Insert the new valve core.
2. Tighten the shaft connection nut to the valve body.
3. Turn valve lever in the direction of flow so the shaft can go through the body.
4. Push the shaft forward and immediately tighten the locking nut to the shaft connection nut.
5. Turn the shaft clockwise until the valve core is installed completely.
6. Loosen the looking nut and back up the shaft.
7. Once the valve core is in place, pull the shaft back and close the valve.
8. Remove the shaft from the valve body.
9. Slowly open the valve knob to assure the valve core is in place. If the valve is not in place,
the pressure in the system will dissipate quickly. If so, quickly close the valve and try again.
Charging system without valve core
The system can be“quick charged“after removal of the valve core. Using manifold gauge set
with valve lever in closed position, connect the correct charging hose to the valve (FIG 2A) Open
the valve and charge the system. After charging, close the valve and disconnect the hose. Proceed
with valve core installation.
