Ret
raction/Removal Procedure
Caution:
For applications where the process media is pressurized to greater than 50 psig (3.5 barg), FCI retractor tool, part no.
026854-01, must be used to safely retract the probe from the process (does not apply to applications using the
medium pressure packing gland assembly with support rods). For applications where the process media is
pressurized to equal to or less than 50 psig (3.5 barg), the flow element can be safely guided by hand. When using
hands to restrain the retraction, be prepared for a rapid pressure impulse of the flow element. Check first that there
are no objects directly behind the flow element as the insertion probe may retract very quickly.
1. Manual Flow Element Retraction: Retraction by Hand (Pressure: 50 psig [3.5 barg] max.) or Using Med. Pressure Packing
Gland Assembly with Support Rods (Pressure: 500 psig [35 barg] max.)
a. Loosen the socket head cap screw on the side of the locking collar. See Figure 7 below.
Figure 7 – Packing Gland Locking Collar
b. Low Pr
essure (max. 50 psig [3.5 bar(g)]): Slowly loosen the packing nut until the insertion probe begins to retract. Use hands as
needed to help control the retraction. If the probe does not begin to retract itself, gently shake and pull the insertion probe until
the flow element has been fully retracted into the packing gland.
