3. Attach the lower clamp and tighten so that it remains in
place, but loose enough so that there is still room to place
the guide tab from the Jupiter between the inside of the
clamp and the outer diameter of the MLI chamber. See
Figure 1.
4. The upper clamp will need to be open to a large enough
diameter to be able to mount to the MLI as well as the
probe. The upper clamp should be positioned just above
the
3 ⁄
4
" NPT threads. See Figure 2.
5. Mount the Jupiter guide pin in the lower clamp and tighten.
If necessary, use strapping tape to temporarily hold in
place on the MLI. See Figure 1.
6. Position the upper clamp to attach the unit to the MLI
and tighten. See Figure 1.
7. Discard any tape temporarily holding the Jupiter to the
MLI.
1.4.2 Internal, Direct Insertion
Use caution when handling probes to ensure probe is not
bent during installation. A bend in the probe may prevent
float from traveling freely up and down the probe.
Caution: Do not rotate the Jupiter electronics enclosure or any
threaded fittings. Rotating the electronics enclosure will
void warranty and could cause damage to sensor cables.
NOTE: Direct Insertion models may be calibrated prior to installation
by positioning the float at the desired 4 mA & 20 mA points.
See Section 1.6 for calibration details.
1. Verify float will pass through vessel opening, if not, it will
be necessary to attach the float after the probe is installed.
2. Carefully insert probe into vessel and thread or bolt to the
mating connection as appropriate.
3. The float is held on the probe by a C-clip inserted into a
groove machined into the tip of the probe. The float is
attached or removed by removing and reinserting the
C-clip. See figure 3. To ensure proper float orientation, the
float is marked “Up
”. ©
