SM-2003U Instrument Connections
The GX-2003 fits into the SM-2003U as shown in Figure 4 below. A
coiled black tube with a plastic push-on fitting resides in a recess in the
left rear corner of the top of the module. The coiled tube routes gas to the
GX-2003 and extends to connect to the GX-2003’s inlet fitting. A straight
green tube comes out of the top of the module to the right of the coiled
tube and also has a plastic push-on fitting on its end. The fitting on this
tube is pushed onto the GX-2003 exhaust fitting and routes gas away
from the GX-2003.
