The magnetic core at the valve axis must be secured with an anaerobic
adhesive. The valve must close reliably and not have any contact with the
head end of the coil body.
Check that the valve spindles move easily (possibly lubricate with
silicone grease). Check that the O-rings of the valve spindles ( O-ring 12
x 1 ) are not damaged; replace if necessary.
When fitting the front panel, ensure that the springs are correctly
positioned in the spring spindle guides.
Before tightening the front panel again, check that the patient part
functions correctly. Check that the front panel fits correctly according to
its outer contour.
Finally, test the patient part with a flow of approx. 5 l and a patient tube
system with test lung at the ventilator. Control and readjust the knobs if
necessary.
Fit the plate knob in such a way that a pressure of 60 mbar is just reached
when the knob is turned right round to the right.
Fit the PEEP knob so that 10 mbar is achieved at the start of the bright
section when the knob is turned right round to the right.
