Agilent Pump G7112B

Warning: Liquid dripping into the electronic compartment of your module can cause shock hazard and damage the module

Note: A solution of 70 % isopropanol and 30 % water might be used if the surface of the module needs to be disinfected.

Did you use a soft cloth slightly dampened with water, or a solution of water and mild detergent?

Did you avoid using organic solvents for cleaning purposes?

Did you ensure not to use an excessively damp cloth during cleaning?

Did you drain all solvent lines before opening any connections in the flow path?

Preparations: Switch off the pump at the main power switch.

CAUTION: Damage of the pump drive - Never start the pump when the pump head is removed.

NOTE: Both pump head assemblies use the same internal components. In addition, pump head A is fitted with the purge valve. The following procedure describes the removal and disassembly of pump head A (left). For pump head B (right) proceed in the same way and skip steps that deal with the purge valve.

Disconnect the capillaries at the back of the purge valve holder, the pump head adapter and the tube at the active inlet valve. Beware of leaking solvents.

Using a 4 mm hexagonal key stepwise loosen and remove the two pump head screws.

Unplug the active inlet valve cable from the connector.

Remove the pump head assembly from the module.
