NJEX 610G / 610F ver.11-2023
Section 2: System Installation
Standard System Connections
Required field connections to place the 610G,
610F into operation are as follows:
1. Connect the regulated actuation gas source
(30-60 psi, 2.1-4.1 bar, by customer, refer to
) to the NJEX LVO gas filter
inlet.
NOTE:
At temperatures below 32ºF (0°C), condi-
tioning of the actuation gas supply may be required.
Where the actuation gas supply has a high water
content and/or a low hydrocarbon dew
point, additional actuation gas filtration or heating
of the actuation gas supply may be necessary.
Bottled nitrogen can also be used during cold
operating conditions to avoid condensation in the
actuation gas supply line. In addition, operation at
extreme temperatures will affect seal and o-ring
performance. To prolong the service of seals and o-
rings, adequate heat should be provided to maintain
an operating environment above 32ºF
(0°C).
2.
Connect the pump discharge valve fitting to
the pipeline connection.
Installation Guidelines
• We recommend that the tubing from the 610
NJEX LVO be adapted to 1/8” tubing before it
reaches the sight glass.
• A 50 psi in-line check valve should be located
just before the sight glass. (1/8” in-line C.V.
P/N A3-0438)
•
The sight glass should be fitted with a 1/4”
MNPT x 1/8”t bore through fitting (P/N A1-0283)
and 1/8” S.S. tubing extending through the bore
of the sight glass fitting until it just protrudes
from the 1/4” dripper point.

CAUTION:
Excessive tubing lengths should be avoided.
Installation of the NJEX LVO Odorization system
should be as close to the point of injection and
Odorant Storage Tank as possible. Maximum
tubing length should not exceed 15’ (4.5 meters)
with the tubing size maintained as indicated in
this manual. If longer tubing lengths are required
consult YZ Systems Technical Services at
800.653.9435 or 1.281.362.6500
