3 UNPACKING THE PURIFIER
3.1 Handling
The level of performance depends upon the care and attention to the proper handling of the
purifier. Exposure to non UHP environments, and physical contact of sealing surfaces will
reduce the quality and life of the purifier.
The purifier should be packaged and stored in a clean, dry environment until used. Do not
open until the intended time of installation.
3.2 Unpacking and Inspection
Each purifier is backfilled with argon and sealed in a polyethylene bag. The ends of the
purifier are plugged with caps. Check the label on the outlet connection and verify the
application. “R” refers to rare gas applications.
• Remove packaging containers and materials such as boxes, crates, and cushioning
outside the clean area.
• Do not tear the polyethylene bag. Use a sharp instrument to cut the seal, taking care
not to damage the item inside the bag.
Retain the shipping documentation and packaging for future use (for example,
return of the purifier to Servomex for servicing or repair).
WARNING
Argon (Ar) is a simple asphyxiant. Exposure to atmospheres containing
less than 19.5% oxygen may cause suffocation. Refer to the chemical
supplier’s precautions and the material safety data sheet (msds) before
using.
WARNING
Strict adherence to uhp component handling procedure is required to
maintain the factory specifications.
CAUTION
