W602100880_A - Installation

1. Position the gauge to prevent vibrations. 

Note:

The gauge can be installed in any orientation. We recommend you install the gauge in a 

horizontal to upright position and use a seal with a centring ring and filter to prevent the influx 

of condensates and particles in the measurement chamber.

2. Install the gauge so that the buttons can be accessed with a pin for future 

adjustments.

3. Remove the protective lid and connect the gauge to the vacuum system.
4. Keep the protective lid.
