2.15 Flanged Models FPD350.(H6/H7/H8).E1

Warning. Flanged models FPD350.(H6/H7/H8).E1 are
designed for 'Hot-Tap' installation. Observe all relevant
safety precautions for drilling into pressurized pipelines, and
ensure the process material does not exceed the Torbar's
specified pressure and temperature limits.
Install the Torbar as follows:
1. Install the flanged pipe fitting (stand-off) – see Section
2.18, page 24.
2. Referring to Fig. 2.14:
a. Fit isolation valve

in accordance
instructions.
c. Drill a 6 mm (0.24 in) pilot hole in the process pipe at
the marked position, then drill to the appropriate size
– see Table 2.8.

Note. The gear retraction handle is supplied loose
and can be fitted to either side of the gears.
However, ensure the handle is fitted so that the
Torbar is inserted when the handle is turned
clockwise.
n. Optional geared retraction assembly only – turn
the integral handle clockwise until the Torbar
contacts the opposite side of the process pipe.
o. Fully tighten packing gland bolts
Torbar does not turn. Check for leaks.
