Chapter 3: Installation and Start Up
Overview
This chapter describes procedures to mount the Digester Gas Monitor, make wiring
connections to the monitor, and start up the monitor.
WARNING: Perform all installation and start-up procedures in a known fresh air
environment, an environment free of combustible and toxic gasses and of normal
oxygen content. The Digester Gas Monitor is not in operation as a gas
monitoring device until the start up procedure is complete.
Mounting the Digester Gas Monitor
Perform the following procedure to install the Digester Gas Monitor at the mounting site.
1. Select the mounting site. When you select the mounting site, consider the following
factors:
• Is an AC or DC power source available?
• Is a vertical surface available to mount the Digester Gas Monitor?
• Is there enough room to open the housing door and make wiring and tubing
connections through the conduit hubs and fittings at the bottom of the housing?
• Are the display screen and status lights visible?
2. Close and latch the housing door.
3. The mounting feet for the Digester Gas Monitor are shipped in a separate bag that is
taped to the outside of the housing. Install the mounting feet to each corner on the
back of the housing so that the shortest section of the mounting foot is flush with the
back of the housing and the longest section of the mounting foot is offset away from
the housing. See the figure below.
