Chamber Pressure

If the Chamber Pressure is below 30 psig (2.1 bar):
Turn the flow control valve 1/8-turn counter clockwise, each injection cycle, until the

•
• The actuator may not be closing the ball valve completely or the ball valve may be
faulty.
If the flow control valve is open too far, it will cause high and/or erratic chamber
