Testing Procedures
Tester Setup with FX2 Series Models
HOSE CONNECTIONS
When installing the FXT onto a submersible pumping system with an FX2 Series LLD, care must be taken to
assure proper connection of the hoses. Only submersible pumps equipped with a tank test port allow the closed
loop testing method to work properly.
USE OF EXTENDER HOSES
Certain situations, such as pumps with a deep bury depth, may require ‘extender hoses’ with the FXT. The 5-foot
(1.5 m) hoses are available from V-R as an accessory. See “Parts Description & Replacement Parts List” on page
18.

This is a general overview of the procedure to properly install the FXT and how to set a leak rate at a given pump
pressure by utilizing Figure 2 (Standard pump example) and Figure 3 (the Red Jacket pump example).
