M700 Helium Compressor 8 4 1 Removing Helium Contamination Helium contamination is usually indicated by irregular noisy or intermittent operation ratcheting and sometimes the seizure of the coldhead or cryopump drive mechanism This is caused by the accumulation of frozen contaminants within the compressor load and resulting in interference The source of the helium contamination is due to either e Inadvertent introduction of ambient air into the system o Use of helium with purity of less than 99 999 such as helium gas used for leak detection and welding e Minor contamination can usually be removed by running the coldhead or cryopump for several hours to trap the contaminants in the coldhead cryopump then shutting down the compressor and immediately removing the helium lines at the compressor Then allow for the coldhead cyropump to warm thoroughly and perform the helium cleanup procedures as outlined in the coldhead cryopump manual The steps to remove compressor decontamination 1 Set the helium regulator to whatever the compressor return pressure gauge reads i e 50 PSIG Attach the running purge fill fitting to the return Aeroquip Attach the helium charge line to the running purge fill fitting Loosely attach the running purge vent fitting to the supply Aeroquip Slowly tighten the running purge vent tool until helium is venting from the vent tool Open the regulator valve and watch the compressor pressure gauge The pres
