USE OF SCANNER ACCESSORIES
Swivel Mount
The scanner swivel mount, P/N 60-1664-3 (NPT) (see Figure 10, Item A), is used to adjust the scan-
ner sighting angle after the scanner has been installed, The swivel mount is used as indicated in Fig-
ures 7, 8, and 9.
Heat Insulating Nipple
Heat Insulating nipple, P/N 35-127-1 (NPT), or P/N 35-127-3 (BSP) (see Figure 9, Item B), is used to
prevent heat transfer from the hot sight pipe to the scanner head as well as electrically isolate the
scanner from ground. The appropriate nipple (NPT or BSP) is shipped
with
the scanner.
Sealing Coupling with Quartz Window
The sealing coupling, P/N 60-1199 (see Figure 10, Item B), is used whenever a coupling or a seal is
required for scanner piping. The quartz window blocks furnace pressure, heat gasses and soot from
coming in contact with the scanner and contaminating the lens. The size is one inch U.S. standard
taper pipe thread (Schedule 40, 1” - 11
1
/
2
NPT). When the sealing coupling is used, a 1” “Y” fitting
must be used down stream of it for connection of a purge air supply (plug
3
/
8
” opening). See Figure 7
for piping with the sealing coupling, Item D.
