Pmax Vacuum pressure P1 1. When ejector suction port is covered and made airtight, suction flow becomes zero and vacuum pressure is at maximum value (Pmax). 2. When suction port is opened gradually, air can flow through, (air leakage), suction flow increases, but vacuum pressure decreases. (condition P1 and Q1) 3.
Tighten the fixed orifice again and connect the pilot piping to port P1 using an M5 fitting.
Using a flat head screwdriver, remove the fixed orifice from port P1. 2. Install the fixed orifice facing in the opposite direction (external pilot). Install it carefully to prevent damage to the O-ring. 3. Tighten the fixed orifice again and connect the pi lot piping to port P1 using an M5 fitting.
