Instructions on installing the Electronic Pneumatics Control Board on a 6890 GC
This document provides instructions for installing an electronic pneumatics control (EPC) board, part number G1557A, onto an Agilent 6890 Gas Chromatograph. The guide includes a parts list and required tools, such as machine screws and electrostatic protection equipment.
The installation process involves preparing the gas chromatograph by unplugging power and cooling heated zones, removing specific covers like the pneumatics top cover and RFI cover, loosening rear panels with Torx screwdrivers, and finally installing the EPC board to restore operating conditions.
You need electrostatic protection such as a grounded wrist strap and a Torx T-20 screwdriver.
You must unplug the power cord to avoid a potentially dangerous shock hazard.
Three machine screws that are M4 x 0.7 x 12 mm long are required.
