Correct Positioning of Simulator
Tubing and Clamp
#1 Shows the correct orientation of the
Simulator Tubing Elbow
#2 Shows the correct positioning of the
Simulator Clamp
•Make sure the clamp is tightened all the
way closed
•When sending the simulator in for repairs,
remove the tubing at the clamp and
disconnect the heated tube at the
disconnect joint
•Keep all tubing and the jar at your location
