VENT MODE
Note: the gauge will not display atmospheric pressure.
The pump will automatically go into vent mode when the pump is turned on.

vacuum setting on an application and vent the system.
All programs are quickly accessible in VENT mode by pressing the numeric keypad for each
program number.

AUTO MODE
Press AUTO button or Vacuum Control knob in MANUAL mode to enter AUTO mode
AUTO mode gives you precise control of the vacuum setting via Up/Down arrows, Numeric
Keypad and the Vacuum Control knob. The bottom right of the display shows the set vacuum
setting. The initial vacuum setting must be set via the numeric key pad and enter button. Once
the initial value has been entered the Up/Down arrows, Numeric Keypad and the Vacuum Control
knob will all allow precise vacuum control in AUTO mode. The only exception is when the users
switches from MANUAL mode to AUTO by pushing the Vacuum Control knob
(see MANUAL mode).
MAXIMUM VACUUM MODE

MAXIMUM VACUUM mode closes the valve and sets the pump to the maximum vacuum level.
To adjust the vacuum level in MAXIMUM VACUUM mode you can press the MANUAL mode
button and use Vacuum Control knob to open/close the variable valve (see manual mode) or press
the Anti-BUMPING/FOAMING button to decrease the vacuum level by several torr.
Note: Selecting MANUAL mode while in MAXIMUM VACUUM sets the unit in MANUAL
mode with the valve in the closed (maximum vacuum) position.
