Excessive tubing lengths should be avoided. Installation
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 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 1.936.788.5593.
3. Connect the odorant supply source to the odorant inlet
manifold with the recommended 1/4" stainless steel
tubing,
figure 9. A tank isolation valve should be
incorporated between the storage tank and this
connection,
figure 9.
4. Connect the regulated actuation gas source, of 75 psi
(5.17 Bar) supplied by the NJEX system owner, to
the NJEX gas filter inlet fitting using a dielectric union,
figure 9.
Note: in applications 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
8300G system may be necessary. Bottled nitrogen can
also be used during cold operating conditions to avoid
condensation in the actuation gas supply line. Also, an
actuation gas source pressure of 75 psi (5.17 Bar)
should be adequate in most installations.
5. Connect the pipeline port of the odorant discharge
manifold to the pipeline connection using a dielectric
union and check valve,
figure 9.
6. If a heater option was specified with this odorizer, 120/
240 VAC electricity
refer to the heater wiring diagram,
page 105, should be connected to the electrical inlet
located on the lower side of the enclosure using 1/2"
conduit and appropriate pack off. Power requirements
for the heater are 1.67A for the 120VAC heater, and
.833A for the 240VAC heater. Each heater is a
thermostatically controlled 200Watt unit,
figure 10.
