Step 2: CLEANING
Precision Medical, Inc. recommends using an ultrasonic cleaner for cleaning all non-elastomeric and non-
metallic components. However, cleaning with an all-purpose liquid cleaner and rinsing with clean, warm water
may be substituted. Both methods require thoroughly blow drying all passages before reassembly. Follow the
ultrasonic cleaner manufacturer instruction.
