Installation Instructions
Threaded Version
1. Before inserting the device into its mounting connection, check to ensure the
threads are matching, to avoid damaging them.
2. Simply screw the device into the process connection, and hand tighten, or use a
wrench. A torque of 40 N m (30 ft.lbs) is recommended
Flanged Version
See
Flanged Horn with extension
on page 14,
Raised-Face Flange per EN 1092-1
on page
16, and
Flat-Face Flange
on page 17, for dimensions.
1)
To equalize pressure and keep the liquid level in the bypass constant with the liquid
level in the vessel.
WARNING: For pressure applications, it will be necessary to use PTFE
tape or other appropriate thread sealing compound, and to tighten the
process connection beyond hand-tight.
Note: There is no limit to the number of times a device can be rotated without damage.
