Safety and Handling
When troubleshooting your Waters 600E system, keep the following safety considerations
in mind:
Basic System Troubleshooting Steps
1. Take a step back and look at the system. Check the simple things first. Is something
obvious causing the problem (for example, is an instrument unplugged or
improperly connected)?
Caution: To prevent the possibility of electric shock, never disconnect an electrical
assembly (including the pump interface cable) while power is applied to the Waters 600E
system.
STOP
Attention: To prevent damage to the 600E controller, wait approximately three minutes
once power is disconnected before removing an electrical assembly (including the pump
interface cable).
Caution: When handling eluents, changing tubing, or operating the 600E system in
general, always observe good laboratory practices. Know the physical and chemical
properties of the eluents. Refer to the Material Safety Data Sheets for the eluents in use.
STOP
Attention: Do not touch the integrated circuit chips or other components which do not
specifically require manual adjustment. Damage due to static electricity could occur.
