3.3.2 Weekly Maintenance
•
Check the tubing connected to the internal peristaltic pump. If the
tubing is crimped or blocked, replace it (rinse line: 2.06-mm (0.08-in)
ID Santoprene® tubing, P/N 064521; sample line: 0.64-mm (0.03-in)
ID Santoprene tubing, P/N 064825). Crimped or blocked tubing can
cause unexpected changes in the flow rate.
3.3.3 Monthly Maintenance
•
Clean the fluid path of the syringe pump to remove precipitates (for
example, salts) and eliminate bacterial growth. For instructions, see
Section 5.1 .
3.3.4 Periodic Maintenance
•
Clean the AS-HV external covers, spill tray, rack location mat, and
accessories with a damp soft cloth and diluted mild detergent.
•
When operating the syringe pump in the push mode, check the
backpressure to confirm that it is less than 0.41 MPa (60 psi). This
prevents damage to the distribution valve.
•
Replace the syringe pump inlet and outlet tubing and valve as
required. The frequency of replacement will depend on the duty
cycle, fluids used, and instrument maintenance.
