VACUUM LEAK DETECTOR VL ..

 

 

18/07/2019 

- 13 - 

6.4.1  Extent of the test 

(1)  If necessary, discuss the tasks to be carried out with the person responsible on-site. 

(2)  Heed the safety instructions regarding contact with the stored products present. 

(3)  Monitoring and emptying the condensate traps if necessary (6.4.2). 

(4)  Testing the probe if appropriate (chapter 6.4.3) 

(5)  Check the free passage of air in the interstitial space (chapter 6.4.4). 

(6)  Test the switching values with the interstitial space (chapter 6.4.5). 

Alternatively: test the switching values using the test device (chapter 6.4.6). 

(7)  Test the lift of the vacuum pump (chapter 6.4.7). 

(8)  Check tightness of the leak detection system (chapter 6.4.8). 

(9)  Set up operating state (chapter 6.4.9). 

(10) A qualified person must fill out a test report confirming function and operational safety. 

6.4.2  Checking and emptying the condensate traps if necessary 

(1)  If there are shut-off cocks on the interstitial space, close these. 

(2)  Three-way valve 20 and 21 to position IV to ensure aeration of the connecting lines. 

(3)  Open condensate traps and empty them. NOTE: Condensate traps can contain storage 

product(s), make sure you take suitable precautions. 

(4)  Close condensate traps. 

(5)  Three-way valves 20 and 21 to position I. 

(6)  Open shut-off cocks on the interstitial space. 

6.4.3  Testing the probe 

(1)  If there are shut-off cocks on the interstitial space, close these.  

(Not applicable when the probe is installed separately from the leak detector. Also applica-
ble for section (2) and section (6)) 

(2)  Three-way valve 20 in position IV, thus aeration of the connecting line. 

(3)  Remove probe and check reaction in storage products or water. 

(4)  Establish optical and audible alarm signal on the leak detector. Press the "mute" button if 

necessary. 

(5)  Clean/dry and insert the probe. 

(6)  Move three-way valve 20 to position I and open the shut-off cocks. 

6.4.4  Checking the free passage of air in the interstitial space 

(1)  Connect the measuring gauge to three-way valve 21, then position III. 

(2)  Three-way valve 20 to position IV, thus aeration of the interstitial space. 

(3)  Determine the drop in pressure on the measuring gauge. If there is no drop in pressure, 

establish the cause and eliminate it. 

(4)  Three-way valve 20 and 21 to position I. 

(5)  Remove measuring gauge.
