70 Instructions for use Isolette 8000 plus SW 5.n
Getting started
WARNING
Risk of death or serious injury
A dirty air inlet filter may affect oxygen concentrations, and/or cause carbon dioxide
build-up.
► Check the filter routinely, and change at least every 3 months.
► Use only the filter specified.
8 Check the air inlet filter, which is located under the rear shell of the incubator:
1 Loosen the 2 thumbscrews (A) of the air inlet filter cover, and remove the
cover.
2 Inspect the filter (B). If it is visibly dirty, see Air inlet filter maintenance on
page 151.
The filter is oriented so that the side with the text "THIS SIDE OUT" faces
inside the air inlet filter cover.
3 Install the air inlet filter cover.
9 For systems without servo oxygen control, check the manual air/oxygen system
located under the rear shell of the incubator:
1 Introduce a carefully measured 9 L/min of oxygen into the oxygen input
connector (C) labeled O2 INLET.
2 Using a calibrated oxygen analyzer, check the oxygen level within the hood.
The level reaches the predicted level as indicated on the rear panel of the
incubator (9 L/min should result in 45% to 75% oxygen concentration).
10 Check the X-ray tray:
1 Rotate the locking knobs, and open the front access panel.
2 Pivot the front access panel to the full open position (hanging straight down).
3 Slide out the X-ray tray (A).
