Check to See that the Mounting Hardware is Level and Square If it’s not, use a
rubber mallet to lightly adjust the hardware and recheck

Verify that the ODF Dimension Matches What is Listed in the QIG The ODF is the dimension from outside pipe diameter to face of flange
485

Verify that the ODF Dimension Matches What is Listed in the QIG The ODF is the dimension from outside pipe diameter to face of flange
For Threaded Flo-tap the dimension from the pipe OD to the top of the threadolet is called LMH:485 Sensor Size 1: 1.38-in. (35 mm)485 Sensor Size 2: 1.56-in. (40 mm)485 Sensor Size 3: 2.06-in. (52 mm)

Attached the Full Port Valve to the Mounting HardwareThreaded Flo-tapFirst, thread the guide nipple into the mounting then thread the valve
Flanged Flo-tap
The valve stem should be in-line with the pipe so it will not interfere with the insertion rods
The valve must be a full port valve to allow the Annubar to pass through the valve into the pipe

Drill the Hole by Using a Hot Tap Drilling Machine
Tag with correct drill hole size attached to the Annubar
Guide Ring in Rosemount Supplied Mounting Hardware

After the Hole is Drilled, Retract the Drill Past the Valve and Close the ValveVent drilling machine and remove the per manufacturers
and site proceduresThreaded Flo-tap Flanged Flo-tap
Remember that the hot tap drilling machine is under pressure and exposed to the process fluid

Attach the Fully Retracted Flo-tap Assembly to the Valve
Flanged Flo-tap – Use a hoist strap and crane if needed

To Retract the Annubar – Loosen the Retraction Limiting Nuts
Retraction Limiting Nuts (Same as Insertion Drive Nuts)

Other Installation Considerations During insertion, the rods can twist and the top
plate and support can come out of alignment.– Makes insertion difficult– Hit the top plate with a rubber to put them back in-line
