CAUTION
To avoid reporting faulty data, deterioration
of reproducibility, or damage to the ISE
module and its parts, follow the precautions
listed below:
• Immediately clean up any spills or leaks.

Clean and replenish the cuvette conditioner
bottle.
Every 3 Months
Replace the lamp.
Wash the ISE electrode lines.*
Every 4 Months
Clean the ancillary reagent bottle filters.
Clean the pure-water bottle filters.
Replace the reaction and dilution cuvettes.
As required
Back up system files.
Replace probes.
Replenish the RRV-bath oil bottle.
Perform preventive cleaning of the wash
station lines.
Wash all ISE lines (if contaminated).
Condition the ISE electrodes.
