Dionex ICS-1000, ICS-1100, ICS-1500, ICS-1600, ICS-2000, and ICS-2100 DO NOT OVERTIGHTEN FITTINGS. Overtightening a fitting can restrict the tubing ID, which can cause damage to the system. The split-cone ferrules shown here are especially sensitive to overtightening. Tighten these fittings fingertight only and then tighten them slightly more only if they leak. - Page 6 Preventive Maintenance Instructions Figure 2.

The piston does not come off as part of the pump head assembly because it is captured by a magnetic retention system. To remove the piston after removing the pump head: hold the shaft of the piston (near the base), tilt the piston slightly, and pull the piston away from the pump.
- Page 12 Preventive Maintenance Instructions Removing the Piston Seal from the Head 1. If this is the primary pump head, install a 10-32 fitting plug (P/N 042772) on the outlet check valve. Tighten the plug. 2. If this is the secondary pump head, install a 10-32 fitting plug (P/N 042772) in both the inlet and outlet ports.
- Page 13 Dionex ICS-1000, ICS-1100, ICS-1500, ICS-1600, ICS-2000, and ICS-2100 Reinstalling the Head and Piston Thermo Fisher Scientific recommends reinstalling the head and piston as a single assembly, so that the piston centers itself onto the magnetic follower. 1. Hold the assembled spacer and guide with the drain tubes aligned vertically and press the spacer into the head until it is flush with the indented surface of the head.
- Page 14 Preventive Maintenance Instructions 2. If the O-ring is removed with the valve knob in Step 1, pull the O-ring off the end of the knob (see Figure 9). If the O-ring is not removed with the valve knob, insert a thin object (for example, the bent end of a paper clip) into the cavity in the pump head and carefully extract the O-ring.
