Step 2: CLEANING
Precision Medical, Inc. recommends using an ultrasonic cleaner for cleaning all
non-elastometric 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.
