9. To ensure the correct operating pressure for the suppressor, either one or two
backpressure coil(s) (P/N 045877) must be installed between the cell outlet
and the regenerant reservoir inlet. The number of coils required depends upon
the application flow rate:
Application Flow Rate
Number of Required
Backpressure Coils
Less than 2 mL/min
2
2 mL/min or more
1
a.
For flow rates less than 2 mL/min, verify that two coils are installed.
b. For flow rates of 2 mL/min or more, remove one of the backpressure
coils.
NOTE Refer to the flier Backpressure Coil Pressure Test for
Dionex Suppressors (Document No. 031759)
(shipped with the suppressor) for details about
suppressor operating pressure requirements.
10. Connect the orange gas line from the eluent reservoir to the gas line on the air
regulator outlet.

Installing and Plumbing the Columns and Suppressor
NOTE This section provides brief installation and plumbing
instructions for the columns and suppressor. For
detailed installation information, refer to the column
and suppressor manuals provided on the Dionex
Reference Library CD-ROM (P/N 055405).
1. Remove the guard column, separator column, and MMS III suppressor from
their boxes. Remove the fitting plugs from the ends of each column and from
all ports on the suppressor. Discard the tubing that temporarily connected the
suppressor ports.
2. Plumb the guard and separator columns. Refer to the labels on the tubing, to
, and to the following instructions.
