Page 15: Chapter 4 - Installation
Installation Locate the 75-810 on a table top with the rubber feet on the surface. In this position, the gas in and out connections are on top and the purifier cartridge is in the correct vertical orientation which reduces gas channeling through the getter material. Connect the 75-810 fitting marked GAS IN to the source of carrier helium or argon. - Page 16 GOW-MAC Instrument Co.

Page 17: Chapter 5 - Operation
Operation Start Up The purifier should be purged with an inert gas (helium if -HE or argon if -AR model, minimum purity 99.99%) for at least 10 minutes before powering on. Apply continuous gas flow of 50 to 200 ccpm before and during initial activation. After the 10 minute purge period, switch on power to the 75-810. - Page 18 GOW-MAC Instrument Co.

Page 19: Chapter 6 - Maintenance & Servicing
Maintenance & Servicing Purifier Lifetime In order to maintain proper purification efficiency, do not exceed estimated lifetime of the purifier cartridge. The estimated lifetime (first impurity breakthrough) is 1 year at 400 °C operating temperature, 150 ccpm flowrate, and inlet gas purity of 99.999%. - Page 20 The operator should place a VCR® cap on the inlet and outlet fittings for sufficient precaution before disposal. It is then acceptable to deposit in an approved landfill, in accordance with local, state and/or federal regulations. When disposed of in this manner, the waste poses no known environmental problems.
