Remove side panel of separations module
Some maintenance procedures, such as sample loop and needle and seal-pack
replacement, require that you remove the side panel of the separations
module to access internal components.
Note: This section only applies if you are using the column heater or column
heater/cooler option and need to remove that unit to access the side panel on
the separations module. If you are not using this option, consult the
appropriate maintenance item for side panel removal instructions.
