See Appendix A for safety advisory information.
Resolving leak sensor errors
After approximately 1.5 mL of liquid accumulates in the leak-sensor reservoir,
an alarm sounds, indicating that the leak sensor detected a leak.
Note:
Small column leaks can be undetectable because they can evaporate
before reaching the leak sensor reservoir.
Required materials
• Cotton swabs
• Gloves: clean, powder-free, chemical-resistant
• Nonabrasive, lint-free wipes
Warning:
To avoid electric shock, do not remove the instrument’s panels.
There are no user-serviceable items inside the instrument.
Warning:
Risk of tipping. To avoid injury, ensure the side-mount shaft
on the right-hand side of the sample manager is engaged in the key-hole
slot on the mounting bracket on the left-hand side of the CM-30S. For
information on securing the CM-30S to the system stack, see page 24 .
Warning:
To avoid personal contamination from contact with
biologically hazardous or toxic materials, always wear clean,
chemical-resistant, powder-free gloves when performing this
procedure.
Notice:
To avoid scratching or damaging the leak sensor,
• do not allow buffered solvents to accumulate and dry on it;
• do not submerge it in a cleaning bath.
