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 15’
(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 281.362.6500.

Note: In applications where the actuation gas supply
has a high water content and/or a low hydrocarbon dew
point, additional actuation gas ltration or heating of the
7300G 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.

120 / 240 VAC electricity refer to the heater wiring
diagram, page 106, should be connected to the
electrical inlet located on the lower side of the
enclosure using 1/2” conduit and appropriate pack
o. Power requirements for the heater are
1.67A for the 120VAC heater, and .833A for the
240VAC heater. Each heater is a thermostati cally
controlled 200Watt unit, gure 10. Dual unit enclo
sures may have dual heater elements. Values
provided are per heater element.
