Connecting Gas Sample and Exhaust Lines
Overview
A single gas-sample line needs to be run from the HGMSZ to the area of the facility to be monitored. An
optional exhaust line can also be installed to vent refrigerant gas away from the monitor. All tubing
connections are made on the bottom of the enclosure as shown in the illustration below.
