4 Maintenance

The flow path components in Pump P-960 have a limited lifetime,
which depends on the flow rate, pressure and eluents used.

4.1

Periodic maintenance

WARNING!

Always disconnect the power supply before attempting to

replace any item on the unit.

WARNING! HAZARDOUS CHEMICALS.

Incorrectly fitted tubing

might loosen, causing a jet of liquid to spray out. This is especially
dangerous if using hazardous chemicals. Connect the tubing by first
inserting the tubing fully, then tightening the connector fingertight.

CAUTION!

Only spare parts approved or supplied by Amersham

Biosciences may be used for maintaining and servicing the pump.

Interval

Action (see procedures below)

Daily

General care

When required

Replace the O-rings in the connection part.

Clean the check valves. If necessary, replace the
O-rings or the check valves.
