8.1 Cleaning the Sensor Clip
The CRIT-LINE Sensor Clip is a sensitive electro-optical assembly critical to the successful operation
of the CLM III monitor. The outside surfaces of the sensor clip can be cleaned with the same
cleaning agents used to clean the dialysis machine. It is recommended that a standard dilute bleach
solution or any of the several varieties of surface disinfectants be used. The use of any commercial
window cleaner or vinegar and water can be used to clean the inside surfaces of the Sensor Clip. If
disinfection is necessary, the several varieties of surface disinfectants (i.e. Cavicide, Envirocide,
etc.) can be used. These cleaning agents should be wiped, NOT SPRAYED, onto the Crit-Line.
Do not immerse the Sensor Clip!
WARNING: Do not use abrasive materials, alcohol, or solvents to clean the sensor clip.
Such materials may damage the sensor clip.
The Sensor Clip assembly is potted with silicon in an effort to seal the clip electronics
from liquids. If liquids infiltrate the Sensor Clip electronics, they will corrode. This
corrosion will cause malfunction of the CLM III monitor and the unit will require
factory repair. If a failed clip has been sprayed and dried as outlined above for normal
cleaning, warranty repair of the unit will remain in force. Monitors for repair with
evidence of immersion of the sensor in solvents or liquid will not be covered under
warranty.
