Section 2: System Installation Standard System Mounting Figure 5 2. In order to satisfy NEC requirements you must connect a ground wire from the grounding lug located on the enclosure leg to a properly installed ground rod, located adjacent to the system enclosure. *Resistance to ground must be less than 1 Ohm. To assure proper system operation this ground should not be a shared ground with any other equipment. 1. Bolt down the system enclosure to a concrete slab using the mounting holes (9/16”) provided in the bottom of each leg of the enclosure. Recommended bolt/stud sizes for mounting the...

Section 2: System Installation Standard System Connections Required field connections to place the 7300G into operation are as follows: 1. Connect the solar panel cable to the system power supply, sps-12, figure 6. Note: the solar panel should be mounted free of obstructing shade and should be facing south in the northern hemisphere or facing North in the southern hemisphere. 1a. *If your system was ordered with the optional LPS120/240 power supply, AC power should be connected in accordance with explosion-proof code via a termination junction box (not shown) to be attached to the conduit provided...

Section 2: System Installation CAUTION: 6. 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 Service Department at; 800.653.9435 or 281.362.6500. 3. Connect the odorant supply source to the odorant inlet mainfold with the recommended 1/4” stainless If a heater option was specified with this odorizer,...

Section 2: System Installation The NJEX SkidMount Series of odorization systems is a total system approach to odorization. These systems are completely factory assembled, tested, and delivered requiring only three field connections to be fully operational. The NJEX SkidMount Systems offer all the advantages of our standard 7300G Systems plus the added benefit of an onboard odorant storage tank. The configuration allows for a total systems approach to odorization. The SkidMount Systems come standard with an electronic level indicator factory connected to the N-300G controller. The controller has...

Section 2: System Installation • Bulk Odorant Filter, figure 12, provides primary odorant filtration between the storage tank and the NJEX-7300G. The bulk odorant filter is preinstalled inside the system enclosure attachment to the odorant source is via a bulk filter manifold equipped with 1/4” FNPT connection located on the back of the system enclosure. • Mechanical Interconnect Cable, figure 12, provides the connection between the system control enclosure and the electrical components located in the mechanical section. • Expansion Tank, figure 13, provides a closed loop system for pressure...

Section 2: System Installation Skid System Mounting Figure 15 1. Prepare a concrete slab that exceeds the NJEX skid length and width dimensions by at least 12”. 2. When moving the system into place follow these lifting guidelines: a. Lift containment skid systems using all four eyebolts on the corners of the skid. b. Lift rail skid systems from the bottom of the skid by forklift or other supportive device. c. Do not move a system with liquid in the odorant tank. d. Do not lift a system by the tank lugs, these lugs are designed only for the weight of the empty tank. CABINET Either Either Single...
