Installing a purge kit

Purging your instrument protects the internal components from moisture and other
environmental contaminants by maintaining an internal atmosphere of dry air or nitrogen. If
your instrument is not already equipped to purge, you must install a purge kit. To install a
purge kit, use the following procedure.
Notice: We recommend that you maintain seal and desiccation and/or purge your instrument
at all times. Equipment damage due to failure to maintain seal and desiccation and/or purge is
not covered under the warranty. If you have questions about this requirement, contact us.
Time needed: 30 minutes or less
Tools needed: A 3/4 inch open-ended wrench
An 11/16 inch open-ended wrench
A shutoff valve (with a 1/4 inch male or 3/8 inch female fitting)
Pipe tape
Note: To order parts, contact us.
Note: For best results the purge gas should be dried to a dew point of -70 degrees C
(-94 degrees F) or below.
Warning: Never use a flammable gas to purge your instrument. The purge gas must be
free of moisture, oil, carbon dioxide and other reactive or infrared-absorbing materials. To
prevent laser damage, use only dried air or nitrogen to purge your instrument.
1.—Install a shutoff valve and either a 1/4 inch male fitting or a 3/8 inch female fitting on the
purge gas source. (Choose a shutoff valve and fittings that are appropriate for the purge
gas source.)
2.—If you used a 1/4 inch male fitting, proceed to the next step.
If you used a 3/8 inch female fitting on the purge gas source, install the 3/8 inch to 1/4
inch reducing nipple that was included with your purge kit. Wrap the reducing nipple with
Teflon pipe tape before you install it, and use an 11/16 inch open-ended wrench to tighten
the connection.
