Do not disassemble the pump head unless there is good reason

to believe that there is an internal leakage. A sign of leakage

is increasing pump rinsing solution volume. Always make sure

that sufficient spare components are available before attempt-

ing to replace a spare part.

example, some individual parts of the pump head can be as-

sembled incorrectly. Check the orientation of each part before
