Mag Probe Installation
UST/AST Tank - Dedicated Riser
1.
Turn Off power to the console.
2.
Remove any sludge from the bottom of the tank.
3.
Check that floats, boot, and cable are assembled correctly on probe.
4.
Gently slide the float(s) to the bottom of the probe shaft before lifting the probe canister. Carefully lower the
probe shaft into the riser pipe until the boot rests on the bottom of the tank [See Figure 15 for UST installation
or Figure 16 for AST installation].
CAUTION! Handle probes carefully. Striking or dropping the probe will result in loss of calibration and could
cause permanent damage.
UST RISER CAP ATTACHMENT
1.
If you are using the one piece cap (see Figure 9 on page 15), push the end of the probe cable through the
cord grip bushing and nut on the cap, leaving a minimal amount of slack between the probe and cap. Screw
the cap onto the riser by hand until the gasket first contacts the pipe. Then lightly tap the cap with a hammer
to tighten it an additional 3/4 turn. Go to Step 3.
2.
If you are installing the metal cap and ring (see Figure 10 on page 16), screw the ring onto the 4-inch riser
until the gasket contacts the pipe, then use a pipe wrench to tighten it an additional 3/4 turn. Using UL-
classified pipe sealant (suitable for the fuels involved), screw the cord grip fitting into the tapped hole. 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 (P/N
312020-
952) onto the riser adaptor by hand until the gasket contacts the sealing surface. Then use a torque wrench
attached 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 17).
3.
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 (see Probe Field Wiring on page 28).
AST RISER CAP ATTACHMENT
1.
If you are using the one piece cap (see Figure 9 on page 15), push the end of the probe cable through the
cap and cord grip bushing, leaving a minimal amount of slack between the probe and cap. Screw the cap onto
the riser by hand until the gasket first contacts the pipe. Then lightly tap the cap with a hammer to tighten it an
additional 3/4 turn. Discard the cord grip nut and attach the Adaptor Nut from the AST kit to the cap (see
Figure 8 on page 14). Tighten the Adaptor Nut until the cable is held firmly. Go to Step 3.
2.
If you are installing the metal cap and ring (see Figure 10 on page 16), screw the ring onto the 4-inch riser
until the gasket contacts the pipe, then use a pipe wrench to tighten it an additional 3/4 turn. Using UL-
classified pipe sealant (suitable for the fuels involved), screw the cord grip fitting into the tapped hole and
tighten. Place the cord grip bushing in the fitting. Discard the cord grip nut and loosely screw the Adaptor Nut
from the AST kit onto the cord grip fitting (see Figure 8 on page 14). Push the cable through the metal cap,
bushing, and Adaptor nut, then clamp the cap onto the ring. Make sure there is a minimal amount of slack
between the probe and cap, then tighten the Adaptor Nut until the cable is held firmly.
3.
Next assemble the liquidtight connectors on both ends of the flexible conduit as shown in Figure 8. Push the
cable through the flexible conduit assembly and into the J-box. Connect the flexible conduit assembly to the
