1. LACGircunowcis _ HELIUM SNIFFER PROBES USER GUIDE OVERVIEW e When using a helium sniffer probe to test pressurized components or system ensure that there are no gross leaks in the system prior to pressurizing Gross leaks will allow the surrounding air or background to become contaminated with helium which lowers the sensitivity of the leak test e When venting helium from a pressurized test part do not vent in the same area where the testing is performed This will contaminate the surrounding air with helium USE OF PROBE TIPS The sniffer probe tip uses vacuum which can pull oil grease and other e When sniffing a part with multiple potential leak locations contaminants into the always begin sniffing near the bottom of the part and work line that may be harmful towards the top It may be necessary to repair leaks that are to the sniffer probe and found before proceeding Helium escaping from the part will leak detector Make sure rise and can give a misleading leak location the probe tip does not get plugged e When the ambient air is contaminated with helium a large fan can be used to exhaust the test area and provide clean air PROCEDURE 1 Connect Sniffer probe to Sniffer Test Port for the leak detector you are using For Alcatel leak detectors the sniffer port is located in the rear Refer to the leak detector user manual for instructions CAUTION Follow precautions to ensu2. re safe operation e Do not allow moisture to be drawn into the probe 2 Sniff leak test per the leak detector user manual i e Do not inhale helium gas instructions Helium is non toxic but may cause suffocation Lack of sufficient oxygen can cause serious injury or death Refer to Material Safety Data Sheet 3 While testing do not plug or contaminant the sniffer probe tip If the probe becomes plugged or dirty remove the clear tube and filter assembly from the tip Replace with a spare unit supplied with the sniffer probe Slide the clear tube over the stainless steel tube so the filter rests on the loop on the end of the probe tip T SPARE PARTS LIST PART NUMBER DESCRIPTION Tip Filter Assembly a i sP 01HS LMSA92125 0 Tip Replacement Assembly LSP 01A A A oaae tF w for assistance 3085 West Directors Row Salt Lake City UT 84104 Phone 801 486 1004 Fax 801 486 1007 info lacotech com www lacotech com CREATING VACUUM AND LEAK TESTING SOLUTIONS SMT 07 1004 revA2
