Integrated; the ventilator fits in a shroud which has a latching back cover.
Removing the 7900 ventilator from the integrated
machine
Remove the rear panel from the gas machine ventilator shroud.
1. Push the locking clips on the panel toward the center.
2. Allow the panel to hang from its retaining cord.
CAUTION:
w
Do not pull the exhalation valve manifold hoses straight down from the
block assembly to remove them. Too much force is needed if you pull
straight down. This added force can cause the hoses to release suddenly
and possibly cause damage to the valve block or cause injury to the per-
son removing the hose. To remove the hoses, use a careful, light twist-
ing, back and forth movement while you apply pressure downward.
