If the tube end shows signs of mechanical damage
(grooves), cut off the damaged portion.
Connect the other end of the tube to the pressure relief valve c.
Open the main valve a of the gas cylinder completely.
Slowly open the pressure relief valve c and set the manometer d to a
secondary pressure of 4 to 5 bar.
Note
A DLCO overpressure valve that opens at 7.5 bar is integrated
in the device. If you select a higher secondary pressure, the
overpressure valve will open and gas will escape.
Exchange the gas cylinder if the primary pressure drops
below 10 bar!
Warning
Be sure not to confuse the DLCO gas inlet and the FRC gas
inlet.
