  1. Only use the product for gases for which it was designed.
  2. Only use the product in the specified limit values for pressure and withdrawal quantity.
  3. Usage for another type of gas or outside the limit values is prohibited and constitutes misuse.

WARNING

warning

Noise emission

When working on pressurised pneumatic supply, significant noise emission can occur. Acute and chronic loss of hearing may result.

  1. Never perform work on the pressurised pneumatic supply without hearing protection.
  2. Only replace the silencers when the supply is unpressurised.

WARNING

warning

Displacement of atmospheric oxygen

In the event of inert gas leaks, displacement of atmospheric oxygen may occur. Danger of suffocation!

  1. The operator must ensure adequate ventilation and airing in all rooms with gas installations and monitor the oxygen content.

WARNING

warning

Cross-contamination

Cross-contamination of the control air with process gases can result in the control unit being damaged.

  1. Ensure that cross-contamination of the control air line is prevented.

The solenoid valves require a supply of clean dry air or nitrogen filtered to 10μm, at max. 5.5 bar. This is connected via a 4mm push-in fitting on the base of the device as indicated on the label. Any exhaust from the solenoid valves is vented internally and excess pressure build-up is vented to atmosphere via an IP65 breather on the base of the unit.
