3 Clean the pump chambers with lint free cloth.
Ensure all particulate matter is removed. Best
cleaning results will be achieved by removing
all valves (see pages 109, 112) and the
capillary. Inject solvent into each chamber.
5 Reassemble the pump head assembly (see
"Reassembling the Pump Head Assembly" on
page 129). Reset the seal wear counter and
liquimeter as described in the User Interface
documentation.
