UST Installation - Vapor Extractor Riser W/O Coupling Adapter
This type installation is usually a retrofit and is usually connected to the console via direct burial cabling. The site
should already be prepped (all digging, saw cutting, and jackhammering done) prior to Probe Installation (see
Figure 12 on page 13). A piece of flex conduit should be in place as shown to protect the cable.
1. Remove any existing hardware from the Vapor Extractor Riser so that it’s 4” NPT riser threads are exposed.
2. Use the extractor wrench tool (OPW Part Number: 89-0044) to remove the Ball Float Check Valve and
Extractor Cage inside the bottom of the 4” riser. Important! - Ball Float Check Valve and Extractor Cage may
be difficult to remove; use caution.
3. Remove any sludge from the bottom of the tank.
4. Assemble the probe floats, spacer rings, and cable as per the Mag Probe Assembly Manual.
5. Gently slide the float(s) to the bottom of the probe shaft. Important! - Handle probes carefully. Striking or
dropping the probe will result in loss of calibration and could cause permanent damage.
6. Carefully lower the probe into the riser pipe until the boot rests on the bottom of the tank.
7. Ensure that the cord grip nut on the new cap is loose so that the bushing can rotate freely.
8. Thread the probe cable through the bushing and nut on the cap, leaving a minimal amount of slack between
the probe and cap.
9. Install the cap onto the riser, threading it by hand until the gasket first contacts the riser pipe. Then lightly tap
the cap with a hammer to tighten it an additional 3/4 turn.
10. Splice the probe cable to the direct burial cable and seal following instructions shipped with the splice kit.
Observe polarity!
11. Bring the cable down the side of riser and secure into place with the tie wrap.
