Humidity
The relative humidity of the operating environment must be between 20 and 80%, with no
condensation. Operating the LC/MS at a very low humidity may result in the accumulation and
discharge of static electricity, shortening the life of electronic components. Operating the system
at high humidity may create condensation and result in short circuits.
Varian recommends using a combination temperature and humidity monitor at the installation
site.
;
Check the checklist box: Relative humidity maintained between 20 and 80%.
Particulate Matter
Your installation site must not have excessive dust, smoke, or other particulate matter.
Particulate matter may block airflow vents causing the electronics to overheat.
;
Check the checklist box: Installation site is free of excessive particulate matter.
Power Requirements
212-LC
The 212-LC requires 85-264V ac; 47-63 Hz; 60 Watts 100 VA
460-LC
The 460-LC requires 95-240V ac± 10%; 50 - 60 Hz; 200 VA.
325-MS
The 325-MS requires a separate circuit, and the outlet must have adequate amperage capacity
and a reliable ground. The power source must be clean and capable of providing up to
200-240V ac, 50/60 Hz ±3 Hz, 1.0 kW.
325-MS LC/MS
The 325-MS LC/MS requires the following:
• 325-MS: One circuit for the MS, 10A, 200-240V ac.
• MS40+: Varian recommends one dedicated circuit for each pump, which can provide
200-240V ac, 50-60 Hz, 10A. If required, both pumps can use a single circuit that can
provide 200-240V ac, 50-60 Hz, 20A.
• Other modules: See the user manual.
