Mag Probe Installation
Reference manual number 577013-578 for additional installation instructions specific to ATEX requirements.
Each probe supplied by Veeder-Root is accom panied by a Mag Probe Assembly Guide. This assembly guide is used to
ready the Mag Probe for installation into the tank. Once you have assembled floats, spacer rings, and attached the probe
cable, install the Mag Probe. Figure 19 (UST tanks) and Figure 20 (AST tanks) illustrate Mag Probe tank installations.
SPECIAL INSTRUCTIONS FOR UST’S WITH METAL RISER CAPS
If you are installing the metal cap and adapter ring, screw the ring onto the 4” riser until the gasket contacts the pipe,
then use a pipe wrench to tighten it an additional 3/4 turn. Push the cable through the metal cap and cord grip, then clamp
the cap onto the ring.
At sites that require installation of a riser ad aptor (Phil-Tite M/F 4X4 or equivalent) at the top of the riser, do so
following th e manufacturer’s instructions. Next screw the adapter ring from the Veeder-Root kit (
P/N
312020-952) onto
th e rise r ada pto r by h a nd u nt i l th e g ask e t co n ta ct s th e sea l in g surf ac e. Th en use a torqu e w ren c h at t ach e d to an
appropriate strap wrench (K-D Specialty tools nylon strap oil filter wrench, or equivalent) and tighten the ring to 35 - 45
ft-lbs. Loosen the cord grip nut and push the cable through the metal cap and cord grip, then clamp the cap onto the ring
(see Figure 21).
Make sure there is a minimal amount of slack between the probe and cap, then tighten the cord grip nut until the cable is
held firmly. Push the end of the cable through the field J-box cord grip, then tighten that cord grip nut as well. Splice and
seal the wires in the J-box as shown in Figure 24 on page 27.

Concrete slab or packed
earth per NFPA 80
Riser pipe: 2-, 3-, or 4'' API schedule 40
depending on probe type (To prevent
erroneous probe readings, install probe
riser a minimum of 24'' from the submersibl
pump.)
Cord grip seals
Weatherproof junction box with 1/2" NPT
threads (16 cubic inch minimum)
14'' min. dia. manhole
Seal-off, epoxy seal per NFPA spec
Mag Probe
(rests on bottom)
Tank
A = 14" minimum for global mag
plus/mag plus probes. When
installing a probe longer than the
the tank diameter, increase this
minimum dimension to compensate.
(Example: a 7'-6'' diameter tank will
use an 8' probe, in which case you
must add 6" to minimum riser length
'A', i.e., 20").
