NITROGEN GENERATORS
INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
5. OXYGEN MONITORING
Note: In hazardous applications where the oxygen content is critical (i.e., blanketing explosive
chemicals or packaging food for extended shelf life), an oxygen monitor and/ or trace oxygen
analyzer should be used in conjunction with safety interlocks and/or alarm systems to assure
proper nitrogen purity levels at all times.
If an oxygen analyzer is needed, Parker Model 72-730NA, which has built-in alarms for connection
to external relays, may be used. This oxygen analyzer has all the controls necessary to assure safe
and accurate monitoring of the oxygen concentration in a process stream. It can be easily installed
on top of the nitrogen generator and connected to the outlet nitrogen line using appropriate fittings.
6. INSTALLATION
All installation, operation, and maintenance procedures should be performed by suitable
personnel using reasonable care.
6.1 Moving
The Parker N2-120, N2-160, and N2-240 Nitrogen Generators are shipped on a wooden skid.
Use a lifting device designed for moving skidded products to move the generator to its installation
location. Gently move the generator from the skid to its final installation position. Secure to floor
if desired. If a future move is required, the generator should be returned to a skid and moved as
detailed above. For moves over short distances, the generator may be slid on its supporting base
or moved using a two-wheeled moving device.
