Section 2: System Installation
Figure 14
CAUTION:
Excessive tubing lengths should be avoided. Installa-
tion of the NJEX Odorization system should be as close
to the point of injection and Odorant Storage Tank as
possible. Maximum tubing length should not exceed 4.5
meters with the tubing size maintained as indicated in this
manual. If longer tubing lengths are required consult YZ
Systems Technical Service Department at; 800.653.9435
or 1.281.362.6500.
3. Connect the pipeline port, the center 1/4” tubing
connector of the odorant discharge manifold to the
pipeline connection using a dielectric union,
figure 14.
4. Connect the regulated actuation gas source, of 5.2
Bar supplied by the NJEX system owner, to the NJEX
gas filter inlet fitting using a dielectric union,
figure 14.
• For pipeline pressures less than 13.8 Bar
a single cut regulator (Fisher 67 YZ P/N
#A3-0042 or similar) adjustable to provide
5.2 Bar to the linlet gas filter on the NJEX
enclosure should be acceptable.
• P/L pressure above 13.8 Bar need a dual cut
regulation provess:
1. Intall the primary regulator on the pipeline (Fisher
1301 YZ P/N A3-0274 or similar), and adjust it to
provide 10.3 Bar to the secondary regulator.
2. Intall the scecondary regulator at the inlet gas filter
on the back of the NJEX enclosure (Fisher 67 YZ
P/N A3-0042 or similar), and adjust it to provide
5.2 Bar to the NJEX system should be acceptable.
3. 3/8” Stainless Steel tubing shuld be used between
the two regulators.
• Dual pump enclosures, may require larger tubing be-
tween the regulators, and the secondary regulator may
need to have a larger orifice (Fisher 64 or simiar) if both
pumps run simultaneously.
Note:
In applications where the actuation gas supply has
high water content and /or a low hydrocarbon dew point,
additional actuation gas filtration or heating of the NJEX
system may be necessary. Bottled nitrogen can also be
used during cold operating conditions to avoid conden-
satioin in the actualtion gas supply line. Also an actuation
gas source pressure of 5.2 Bar should be adequate in
most installations.

Connect the pipeline port of the odorant discarge
manifold to the pipeline connection using a dielectric
union and check valve,
