The 8100-104 Long-Term Chamber's opaque "bowl" can be swapped out with the clear bowl from the 8100-104C Long-Term Chamber, and vice versa. Upgrade packages are also available from LI-COR that contain all of the hardware required to upgrade either chamber. The upgrades requires 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:
- 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.
- 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 below.
- Unscrew the nut and disconnect the thermistor cable.
- Use the 3/8" wrench to remove the arm mounting nuts and washers.
- Remove the arm assembly.
- For storage, reinstall the flat washer, split washer, and hex nut on each of the PEM studs on the underside of the arm assembly.
- Remove the mounting hardware from the underside of the new arm assembly.
- Place the arm assembly into position on the mounting flange and install the flat washer, split washer, and hex nut finger tight.
- The nuts should be tight enough to hold the arm flat against the mounting flange, but should still allow some lateral movement.
- Adjust the position of the arm assembly so that the bowl is centered over the gasket.
- When centered, tighten the mounting nuts.
- Use the cable clamps provided to attach the cable/tubing assembly to the motor housing.
- Note that the dust cap connector is placed under the lower cable clamp.
- Plug in the thermistor cable and tighten the nut.
