Preparation and operation
Before you prepare a CH-A module for operation, prepare the sample manager and solvent
manager.
Before running samples, you must prepare the CH-A module for operation. To do so, perform
these tasks:
• Install the CH-A module onto the system stack.
• Install the APH assembly, make the column-tubing connections, and install the column.
Alternate:
Install the column-stabilizer assembly, make the column-tubing connections, and
install the column.
• Connect the power and signal interconnect cable between the sample manager and CH-A
module.
Notice:
To avoid damaging the electronic components of the sample manager and the
column heater, always power-off the sample manager before connecting or
disconnecting the column heater's interconnect cable.
• Configure the preheater setting in the console, and control the CH-A module using the
console or the method editor in the chromatography data software.
2.1 Column compartment installation
The CH-A module assembly comprises a rear enclosure that installs onto the sample manager's
chassis, and the column heater that installs within the CH-A rear enclosure. For a standard,
column compartment installation, both of these components are located above the sample
manager. If your system configuration requires a standard, column compartment installation,
perform these tasks:
• Remove the center chassis screw on the rear of the sample manager's chassis.
• Install the CH-A–to–SM retainer bracket onto the top side of the sample manager's chassis.
• Secure the CH-A to the sample manager's chassis.
2.1.1 Installing the CH-A onto the system stack
When properly installed onto the system stack, the CH-A is firmly secured to the top side of the
sample manager's chassis and is positioned so that any leakage from the column compartment
drains from left to right into the sample manager's upper drip tray. This placement also allows any
