Dionex VP
Installation Instructions
1. Introduction
The Thermo Scientific Dionex
™
VP Vacuum Pump (Dionex VP) (see Figure 1) is
a dual-stage diaphragm pump capable of providing a continuous vacuum. The
pump is designed for use with a wide range of IC (ion chromatography)
applications, consumables, and accessories.
There are two modes of pump operation:
• In the manual control mode, the Dionex VP turns on and off when the user
presses a button on the rear panel.
• In the relay control mode, the Dionex VP turns on and off in response to a
signal from the relay output of a controlling device (for example, a Thermo
Scientific Dionex ICS-3000 Detector/ Chromatography Module). Relay
control must be programmed in the Thermo Scientific Dionex Chromeleon
®
Chromatography Data Management System.
When the pump is on, the
VACUUM ON LED on the front panel is lighted.
