6.3 Insertion Procedure for FTMD
1.
Verify that the Flo-Tap insert-retract
mechanism are in the position as shown in Fig.
13.
2. Verify that the Flo-Tap instrument valves {8} are
fully closed and that the unit isolating valve {2}
is fully open (Fig. 13 and 14).
3. Initiate probe insertion by rotating the drive
nuts {10} clockwise as viewed from the top,
using ratchet wrench. The nuts must be
tightened alternately, about two turns at time to
prevent binding resulting from unequal loading.
Continue this procedure until probe contacts the
opposite side of the pipe or end support
(FTMD-26)
4. Inspect the packing gland for evidence of
leakage. If the unit was ordered with high-
temperature gland, additional adjustment may
be required at this time.

5. Connect instrument lines to the instrument
valves and to the appropriate meter, recorder,
transmitter or controller.
6. Open the Flo-Tap instrument valves {8}. Then
purge or bleed the connecting lines and readout
equipment as required.
6.4 Retract Procedure for FTMD
1. Fully close the Flo-Tap instrument valves {8}.
Then, if required, depressurize and disconnect
the instrument lines.
2. Loosen slightly packing gland {6+7} before
proceeding with retraction.
3. Retract the Flo-Tap by rotating the drive nuts
{10} clockwise as viewed from the top, using
ratched wrench. The nuts must be turned
alternately, about two turns a time, to prevent
binding resulting from unequal loading.
Continue this procedure until the probe is fully
retracted as shown in Fig. 14.
