Hold the monitor flat against the mounting surface and allow it to slide down engaging the screw heads in the

keyhole slots of the mounting brackets. Adjust the screws as necessary to hold the monitor securely against the

A single gas-sample line must be run from the HGM-SZ to the area of the facility to be monitored. And an

optional exhaust line can be installed to vent the sample gas away from the monitor. All tubing connections are
