Setting Up The Piston Seal Wash System; 3.13.1 Setting Up The System - Thermo Scientific Dionex ICS-5000+ Installation Instructions Manual

9. The DP/SP does not require pressurized eluent reservoirs. However,
Thermo Fisher Scientific recommends pressurizing reservoirs with
helium or nitrogen under the following circumstances:
•
When using eluents that are sensitive to contamination.
•
When combining aqueous and nonaqueous components (for example,
water and acetonitrile). Pressurizable reservoirs allow eluents to be
stored under a specific atmosphere.
NOTE
For instructions on how to pressurize eluent reservoirs, see

Setting Up the Piston Seal Wash System

Notes for DP Modules
•
The seal wash system is connected to the bottom pump (pump 1) at the
factory. To connect the seal wash system to the top pump (pump 2),
follow the replumbing instructions in
•
To operate a piston seal wash system for both pumps, order one of the
following options. Installation instructions are included with each kit.

3.13.1 Setting Up the System

1. Add ASTM Type I (or better) (18 megohm-cm) filtered and deionized
water to the seal wash reservoir (P/N 064155). The liquid level should be
between the Min. and Max. markers on the reservoir label. Do not
overfill the reservoir.

If an eluent reservoir will not be pressurized, make
sure that one of the ports in the reservoir cap is vented
to the atmosphere.
Dual-Serial External Seal Wash Kit (P/N 063518):
After installation of this option, the DP seal wash pump will
pump wash liquid from an external reservoir to pump 2, then to
pump 1, and out to waste.
Dual-Parallel External Seal Wash Kit (P/N 068661):
After installation of this option, wash liquid from an external
reservoir is pumped through each DP pump separately.
