PPVS-INFUSION TEST PROCEDURES:
PPVS-Infusion Adjustment:
1. Connect the INJECT Output on the control
box to the PPVS supply port using 4 mm tube.
2. Connect the PPVS signal line to the pneumatic
Indicator on the control box.
3. Using the Vacuum Level Control adjust the
vacuum level Up/Down to determine the
vacuum pressure that the valve activates &
deactivates at. The indicator will signal red
when the valve is active.
4. To Adjust/Change the vacuum pressure at
which the valve activates use the 2.5 mm Allen
Key provided. Turn the adjustment screw
Clockwise to switch closer to atmosphere
(nearer to zero) and Anticlockwise to switch
down to -300mb (higher vacuum pressure).
Testing PPVS-Infusion for vacuum leak:
1. Load the PPVS valve into the Universal Insert
Adaptor port.
2. Connect the INJECT Output on the control
box to the PPVS supply port using 4 mm tube.
3. Connect the PPVS signal line to the pneumatic Indicator on the control box.
4. Using the Vacuum Level Control adjust the vacuum to the desired level.
5. Turn the Vacuum Isolator valve to the Closed position (horizontal) to lock the
vacuum level – if the vacuum level moves (leaks) down the seal in the valve is
not holding vacuum.
