Prepare the IMV assembly for removal
DANGER – Serious damage to health / risk to life. Preparation for
removing the IMV should include shutting in the measurement sensor
and disconnecting the high and low input lines or manifold connections.
Depending on company policy, other steps may be required but are
outside the scope of this document. Complete all requirements before
continuing.
The following are general guidelines. Adjust these steps according to the specific site
requirements. To remove the IMV assembly:
1.
Shut in the measurement sensor:
a.
Using the manifold high/low control valves, equalize the pressure to the
IMV.
b.
Using the high/low tap valves, close off both lines. These two valves
connect the meter run high/low output lines to the µFLO.
c.
Vent the manifold to atmosphere using the vent valve.
d.
Completely disconnect the high/low manifold lines from the IMV.
2.
Rotate the enclosure, if necessary, to allow removal of the IMV:
a.
Using a 1/2 inch socket with ratchet, loosen the µFLO enclosure mounting
clamp bolts and rotate the enclosure a sufficient distance to allow removal
of the IMV, approximately 11 inches (28 cm).
CAUTION – Equipment damage. When rotating the enclosure, be
careful to not stress or damage the wires and cables connected through
the enclosure access points.
b.
After rotation, tighten the clamp bolts to hold the µFLO in place.
