Pressure; Vacuum - GE Druck PV 411A Manuel D'utilisation

Pressure

1 Turn the selector valve (7) fully clockwise (in) position.
2 Operate the scissor-action handles (5) to generate the approximate
pressure, allow time for thermal stabilization.
3 If necessary, use the volume adjuster (3) to adjust the required
pressure.
4 After attaining the required pressure operate the scissor-action
handles (5) to generate a higher pressure. Alternatively, vent the
pressure to atmosphere by slowly turning (anti-clockwise) the
selector valve (7) to the centre position.

Vacuum

1 Turn the selector valve (7) fully anti-clockwise (out) position.
2 Operate the scissor-action handles (5) to generate the approximate
vacuum, allow time for thermal stabilization.
3 If necessary, use the volume adjuster (3) to adjust the required
vacuum.
4 After attaining the required vacuum operate the scissor-action
handles (5) to generate a higher vacuum. Alternatively, vent
atmosphere into the vacuum by slowly turning (anti-clockwise) the
selector valve (7) to the centre position.
After completion, depressurize the pump and disconnect from the pipes and
