4.) Remove other in-line leak detection equipment before installing the LSU300 Auto-Learn LLD
5.) Apply UL Classified Gasoline/Oil resistand teflon pipe dope thread sealant to the threads of the
LSU300 Transducer and use a 2-3/8 inch open-end wrench to install it in the Leak Detector Port of
the STP housing (see Figure 2-2)
6.) Apply UL Classified Gasoline/Oil resistand teflon pipe dope thread sealant, assemble, and install the
supplied Needle Valves in the Line Pressure Test Port of the STP and close all Needle Valves (see
Figure 2-2)
7.) Install Couplings, threaded Rigid Metal Conduit (RMC), and Explosion/Weather Proof Junction
Boxes (J-Boxes) in the STP sumps (see Figure 2-2).
8.) Install threaded RMC and EYS fittings along with Transducer Cables (Belden #9365) from LS300
console to the Explosion/Weather Proof J-Boxes (have the licensed electrician splice the cables
together. If this wiring is Intrinsically Safe it MUST NOT be run with any Explosion Proof wiring or
other non-Intrinsically Safe wiring!).
9.) After all LSU300 Leak Sensing Units (transducers) have been installed, check to see that all Needle
valves are closed, and that the system is ready to be pressurized to check for the absence of leaks.
10.) After the installation is checked and all personnel are clear, have the electrician turn on power at the
Power Panel for the STP (Submerged Turbine Pumps and Dispensers).
11.) Turn on the STP at the dispenser (do not deliver product) and check for leaks at each Sump... if
there are any leaks, immediately turn off power, lockout and tag at the Power Panel, use absorbent
rags to clean up the product spills and dispose of properly, and repair the leak(s) and repeat step 10
and step 11 until no leaks remain.
13.) Clean areas where the Danger Labels will be placed so the adhesive backing will stick to a dry
surface that is clean and free of petroleum.
14.) Cleanup and dispose of installation materials, petroleum absorbent and waste material in
appropriate containers.
15.) Stick the supplied Danger Labels (PN: 240-1175) to clean dry areas near
Dispenser Fuel Filters, Pump Controllers, and on the Cable of the
LSU300 Transducer and on the STP housing.
