Maintenance Procedures

The maintenance of the 2410 refractometer described in this chapter involves cleaning the fluidic
path and replacing fuses. When you perform maintenance procedures on your 2410 differential
refractometer, keep the following safety considerations in mind:
Caution: To prevent the possibility of electrical shock, never disconnect an electrical
assembly while power is applied to the Waters 2410 Differential Refractometer.
Caution: To avoid the possibility of electrical shock, do not open the 2410 differential
refractometer cover. The 2410 differential refractometer does not contain user-serviceable
components.
Caution: When you handle solvents, change tubing, or operate the 2410 differential
refractometer in general, always observe good laboratory practices. Know the physical
and chemical properties of the solvents. Refer to the Material Safety Data Sheets for the
solvents in use.
Attention: To avoid damage due to static electricity, do not touch integrated circuit chips
