Before connecting helium to the machine, verify that the pressure regulator on the helium supply
bottle does not exceed 1
12 2 b ba arr. Excessive pressure may cause damage to the internal helium
regulator and therefore damage the CV EBM inlet valve.
1. Helium inlet
1. Connect the helium media supply hose to the Heli-
