WARNING Avoid explosion hazard. Never use a flammable, combustible, or toxic gas to
purge this instrument. The purge gas must be free of oil and other reactive materials. Heat
from the source or from laser absorption may ignite flammable gases or reactive materials
in purge gas. Use only dried air or nitrogen to purge your instrument.
To install a purge kit
1. Install the regulator valve and either a 1/4-inch male fitting or a 3/8-inch female fitting
on the purge gas source. (Choose a 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 from the purge kit. Wrap the reducing nipple with pipe tape
before you install it, and use an 11/16-inch open-ended wrench to tighten the
connection.
