5.5 Tightness test
EXCESSIVELY HIGH TEST PRESSURE
• Verify that the tightness test is performed with a test pressure of <600 mbar.
Failure to follow these instructions can result in equipment damage.
1. Verify tightness of the hose lines (without device) prior to connection to the
interstitial space.
2. Perform the tightness test with no more than 600 mbar.
- The connection lines can be considered to be tight if the pressure drop
within a period of 30 minutes is less than 20 mbar.
3. Connect the connection lines to the interstitial space of the tank after a
successful tightness test.
