2. If you are installing the metal cap and adapter ring (see Figure 7 on page 10), 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 adapter (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 (
P/N 312020-
952) onto the riser adapter 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 11).

A
A = 10" 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., 16").
Split-Ring Collar
(P/N 576008-617)
required if probe
