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 (ref. Mag Probe Assembly Manual).
4.
Gently slide the float(s) to the bottom of the probe shaft before raising the probe. Carefully lower the probe
into the riser pipe until the boot rests on the bottom of the tank [See Figure 9 for UST installation or Figure 10
for AST installation].
WARNING! Handle probes carefully. Striking or dropping the probe will result in loss of calibra-
tion and damage to the probe.

UST RISER CAP ATTACHMENT
1.
If you are using the one piece cap (see Figure 6 on page 9), 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.
