Note: Some underground storage tanks are ballasted
with water during construction. DO NOT use the
submersible pump to remove water from the tank.
The pump is designed for use with petroleum
products only, and pumping other uids will
seriously damage the unit. We do not recommend
immersing the pump in water, but, if this does
happen, immediately ll the tank with motor fuel
after the water is removed from the tank. Severe
corrosion takes place very quickly if the unit has
been submerged in water and is then exposed to
air. If the pump will not operate after gasoline is
put into the tank, remove the extractable portion,
remove the black plastic end cap from the pump
motor assembly (PMA), and turn the Allen screw
clockwise at the end of the PMA. This will break
free the PMA from any corrosion that may be
present. Reinstall the PMA end cap and the
extractable section into the pump housing.
Installer:
This instruction booklet MUST be left with the owner of the
service station at which the equipment is being installed.
Station Owner:
Retain these instructions for future use and provide them
to persons servicing or removing this equipment.
Installation Instructions
The piping and underground storage tank must be installed
using good standard industry practices. There are several
publications that can be used for reference, some of which
are:
Automotive and Marine Service Station Code, NFPA •
30A, Flammable and Combustible Code, NFPA 30, and
National Electrical Code, NFPA 70 (NEC), National Fire
Protection Association, Quincy, Mass.
Recommended Practices for Installation of Underground •
Liquid Storage Systems, The Petroleum Equipment
Institute, PEI / RP100, Latest Edition.
Recommended Practices for Installation of Aboveground •
Storage Systems for Motor Vehicle Fueling, The
Petroleum Equipment Institute, PEI / RP200, Latest
Edition.
Installation of Underground Petroleum Storage Systems, •
American Petroleum Institute, API Recommended
Practice 1615, Latest Edition.
Required Tools
Standard 3 / 4" drive ratchet wrench or breaker bar (no •
sockets required)
Standard at head screwdriver•
Wire cutter and stripper•
5 / 32" Allen wrench for securing set screw in telescoping •
pipe coupling (VL units only)
Pipe wrench (36" minimum) for tightening 4" Riser•
1 / 4" hex driver with socket and ratchet wrench, or 1 / 4" •
Allen wrench for attaching PMA
Measuring tape long enough to reach bottom of the tank •
from 30" to 70" above the tank
Note: All wiring must conform to applicable guidelines in
accordance with all federal, state, and local codes.
Failure to comply with all applicable guidelines
could result in an unsafe installation. Use the
following table for maximum wire length to wire
gauge ratios for submersible wiring:
Wire Size Maximum Run
10 gauge 650 feet
12 gauge 400 feet
14 gauge 250 feet
Preparation
1. Fill out the Warranty Registration Card and return
it to FE Petro.
Note: If your STP / IST does not operate correctly or
there are any questions concerning installation or
service, please contact FE Petro Technical Service
at (800) 225-9787.
2. Disconnect power to the submersible pump at the
electrical supply box (if already installed).
3. Tag and lock out electrical circuit breakers so they
are not turned on accidentally.
If installing xed length pump (non-•
variable) with PMA mounted, go to
“secure to tank” section.
If installing variable length pump •
continue with this section.
If installing xed length pump (non-•
variable) without PMA mounted,
complete “mounting PMA” section,
then go to “secure to tank” section.
