INTERVAL MAINTENANCE OPERATIONS

Frequency*	Maintenance operations
1000 h⁽¹⁾	Clean filters (inlet filters, air inlet filter).
4000 h⁽¹⁾ or 6 months⁽²⁾	Clean the vacuum lines, the valves and the gauges with alcohol - Dust the electronic boards and the fans. Partial maintenance of the analyzer cell. Clean the analyzer cell with alcohol (this cleaning may be necessary in case of general internal contamination creating insulating deposits).

BASICS OF HELIUM VACUUM TEST

Detector switched on («I»): wait until stand-by mode.
Connect the leak detector to the part or installation to be tested.
Start a cycle.
Wait Helium signal stabilization.
With a spray probe, spray Helium around the part or installation to be tested: start from the top.
Leak value measured and test result (accepted or rejected) according to the reject threshold display.
Stop the cycle.
