5. Hazards/Precautions
Note the following hazards and precautions for setup,
operation, and maintenance of the WellMate instrument:
Operator protection
• Always unplug the unit from the power outlet before you
perform any service or maintenance task that does not
require power.
• Do not touch nozzles or the stage when the unit is
operating.
Base-unit protection
• Use only dilute detergent cleaning solutions to clean the
unit. Do not clean the keypad with bleach solutions or
other solvents. To clean the unit, fi rst remove the tubing
assembly from the instrument. Then use a bleach
solution (2%) or an aqueous-based cleaner to clean
surfaces. Rinse solution completely from surface.
• If liquid leaks out of the tubing onto the stage or onto
any other part of the instrument, stop the operation
immediately and then wipe off the liquid.
Tubing-cartridge protection
• Inspect the nozzles and nozzle tips regularly to ensure
that the tips are not clogged and that there is no debris
in the nozzles. Clean them regularly following the
procedures described on page 39.
• Be careful not to bend the nozzles.
