Before You Begin
1. Install the three WPLLD modules below in the TLS-350 Series Console following instructions shipped with each
module. If these modules are not installed, the console will not be able to accept inputs from the WPLLD system.
-
Wireless PLLD Communication Module (Part no. 847490-309)
-
Wireless PLLD AC Interface Module (Part no. 847490-209)
-
Wireless PLLD Controller Module (Part no. 847490-208)
IMPORTANT! WPLLD modules are not interchangeable with PLLD modules.
2. A 1-1/2” socket is recommended for installing the SwiftCheck
™
valve in small manways (24”).
3. If you are running 0.1 gph or 0.2 gph tests, be sure you have purchased the Software Enhancement Module which
provides this capability. IMPORTANT! If the correct hardware for precision line leak testing is also not
installed, the system will not detect leaks less than 3.0 gph. In this situation, the system will always pass 0.2 and
0.1 gph tests, but the results will not be valid.
4. Ensure that the submersible pump is properly grounded per the manufacturer’s instructions.
5. Ensure that there is at least 4 inches clearance above the submersible pump capacitor housing to allow room to install
the WPLLD components.
6. Ensure that you have UL-classified, non-toxic pipe sealant suitable for the fuel(s) involved.
System Description
The WPLLD System performs 3.0 gph leak tests following each dispense. If the appropriate software enhancement
module is installed, the WPLLD System also allows line tests at full pump pressure for highly accurate 0.2 and 0.1 gph
tests. Since WPLLD executes these tests automatically, there is no need for separate annual line leak testing.
Table 1-1 shows required kits and check valves for WPLLD operation, by pump type. Table 1-2 through Table 1-5 list
the contents of the five WPLLD system kits and Table 1-7 lists the contents of the Non-Vented SwiftCheck Valve kit.
