Tips for keeping your Agilent® UHPLC in good working order :
To keep the module case clean, use a soft cloth slightly dampened with water, or a solution of water and mild detergent. Avoid using organic solvents for cleaning purposes. They can cause damage to plastic parts.
To replace the inlet weaver, switch off pump at the main power switch, open the doors. Use an optional solvent shutoff valve or lift up solvent filters inside solvent bottles to avoid leakages. For easy access to the inlet weaver assembly, remove tubing connections between MCGV and degasser.
When disassembling your pump heads, seals must be exchanged and pistons must be cleaned in both primary and secondary pump heads.
When replace parts of the inline filter, the inline filter can be cleaned using the back-flush function in the user interface of your Agilent instrument control software. Only use the back-flush option, if an inline filter is installed.

Agilent® UHPLC Troubleshooting Tips:
If you diagnose a dynamic Leak > 30 μL/min or your Dynamic Leak Rate Test fails:
There might be air in the primary pump chamber. Check for air in the solvent inlet lines and the Tuning signal; Purge the lines, condition and if necessary prime the pump head.
There might be a leak in inlet valve. Check for moving air bubbles in tubing directly to the inlet valve. Purge the lines with water to remove dirt. Knock at the valve, clean it or replace it.
The outlet valve might not be properly assembled. Retighten the outlet valve and check the position of the gold seal.
You might have leaky piston seals and/or position-dependent leaks on the piston. Remove the SW tubes from the support ring and check for leaks. Replace the piston seals and clean the pistons. Ensure that seals are lubricated when pushed in (use abrasive mesh > 5000 grit).
