Connecting the Chamber to the Analyzer Control Unit
There are three hoses connected to the Survey Chambers; air to the chamber, air
returning from the chamber to the Analyzer Control Unit, and air that drives the
bellows. These hoses are connected to the side panel of the Analyzer Control Unit,
as shown in Figure 6-5. The Air In hose has a male fitting, and the Air Out hose
has a female fitting. Note that one of the hoses has a piece of black shrink wrap;
this hose attaches to the Air In fitting on the Analyzer Control Unit. The bellows
hose has a male fitting, and attaches to the port marked Bellows on the Analyzer
Control Unit. Insert the hoses until the fittings snap into place. To remove the
hoses, slide the collar on the fittings and pull straight out.
