• Connect the free end of the air line to the “Span Gas” port of the UGC.
• Form the length of the air line into a coil and store in a non-obtrusive location.
Assembling the Exhaust Ports
• Locate the Exhaust Port Filter Assembly. It consists of a 1/4" tee fitting already connected with short
lengths of red and blue air line and a Parker/Balston particle filter.
• Fully insert the free end of the 1/4" blue air line into the “Reference Exhaust” port of the UGC.
• Then fully insert the free end of the 1/4" red air line into the “Sample Exhaust” port of the UGC. The
filter should now be oriented horizontally, projecting away from the UGC.
