Binary Solvent Manager maintenance procedures:
Maintenance

Replace the leak
sensor
Replace the mixer
Replace the pump
interconnect tubing
2
Replace the i Valve
cartridge
Frequency
As needed. For example, when the leak sensor is
damaged or an error message states the leak sensor
is not detected.
Replace as part of the annual scheduled routine
maintenance and, thereafter, as needed. The
typical failure modes are as follows:
• You see a visible leak.
• You see erratic retention times.
• The mixer assembly causes a high pressure
shutdown.
Replace as part of the annual scheduled routine
maintenance and, thereafter, as needed. The
typical failure modes are as follows:
• You see a visible leak
• The system exhibits a high pressure shutdown
and the pressure decays when the connection
after the tubing is broken.
Replace as part of the annual scheduled routine
maintenance and, thereafter, as needed. The
typical failure modes are as follows:
• Late eluting peaks are exhibited and/or after a
dynamic leak test was performed where the leak
rate is above the acceptable limit.
• The solvent manager exhibits a low or erratic
flow rate/ pressure pulsations.
• An intelligent intake valve error message occurs.
