VACUUM LEAK DETECTOR

(4) Close condensate traps.

(5) Three-way valves back to the operational setting.

(6) Re-open the cocks closed under No. (1).

7.3.2 Continuity test of the interstitial space

The continuity test checks that an interstitial space is connected to
the leak detector and that it has sufficient continuity for an air leak to
cause an alarm.

(1) Connect test measuring instrument to the spout of the three-way

valve 21 and rotate the tap by 180°.

(2) For pipes:

Open test valve at the end away from the leak detector. If there
are several pipe interstitial spaces, the test valves are to be
opened one after another at each end away from the leak detec-
tor.

For tanks:
Rotate three-way valve 20 by 90° (clockwise) so that the suction
line and thus the system are ventilated.

(3) Note underpressure loss on the measuring instrument. If there is

no pressure loss, locate and rectify the cause.

(4) Restore operating position of the three-way valves and remove

test measuring instrument.

7.3.3 Testing the switching values with the interstitial space

(1) Connect test measuring instrument to the spout of the three-way

valve 21 and rotate the tap by 180°.

(2) For pipes:

If several pipe interstitial spaces are connected via a manifold, it
is recommended that all interstitial spaces except one be shut off.
Open test valve at the end away from the leak detector.

For tanks:
Rotate three-way valve 20 by 90° (clockwise) so that the suction
line and thus the system are ventilated.

(3) Determine the switching values for "Pump ON" and "Alarm ON"

(with visual and, if available, audible alarms). Note values.

(4) If appropriate, activate “Acoustic alarm”.

(5) Turn three-way valve 20 back or close test valve and determine

“Alarm OFF” and “Pump OFF” switching values. Note values.

(6) The test is considered to have been passed if the measured

switching values are within the indicated tolerance range.

(7) Open previously closed shut-off cocks.

(8) Restore operating position of the three-way valves and remove

test measuring instrument.
