9981-078 and 9981-160 Chamber Bowl Assembly Instructions
Chamber's opaque "bowl" can be
swapped out with the clear bowl from the
8100-104C Long-Term Chamber, and vice
versa. Upgrade packages (9981-078 and 9981-160) are also
available from LI-COR that contain all of the hardware
required to upgrade either chamber. The upgrade(s) require
only a 3/8" combination wrench and an 11/32" combination
wrench or nut driver. Follow these instructions to change
the chamber bowl on the 8100-104 or 8100-104C:
1. Make sure that the chamber drive column is in the
"Park" position before starting. If the chamber is not
parked, press the OPEN/CLOSE button twice to park.
2. Use the 11/32" wrench or nut driver to remove the two
hex nuts that secure the cable/tubing assembly to the
side of the motor housing, as shown in Figure 2. Un-
screw the nut and disconnect the thermistor cable
(Figure 2).
3. Use the 3/8" wrench to remove the arm mounting nuts
and washers (Figure 3). Remove the arm assembly.
4. For storage, reinstall the flat washer, split washer, and
hex nut on each of the PEM studs on the underside of
the arm assembly you removed in Step 3.
