Mag Probe Installation
A = 10" minimum for global mag
plus/mag plus
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., 16").

2. If you are installing the metal cap and adapter ring (see Figure 18 on page 25), 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 adaptor (Phil-Tite M/F 4X4 or equivalent) at the top of the riser, do so
following the manufacturer's instructions. Next screw the adapter ring from the Veeder-Root kit (
952) onto the riser adaptor by hand until the gasket contacts the sealing surface. Then use a torque wrench at-
tached to an appropriate strap wrench (K-D Specialty tools nylon strap oil filter wrench, or equivalent) and tight-
en 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 22).
Use bushing and body of grip
fitting supplied with probe and
Adaptor nut supplied with
AST kit.
