Housing

The sample-draw detector’s fiberglass housing is weather- and corrosion-resistant. It is
suitable for installation where general purpose equipment is in use. The housing door is
hinged on the left side and is secured by two latches on the right side.

Four mounting feet are attached to the back of the housing (one at each corner). Use the
mounting feet to install the housing to a vertical surface. Use the two conduit hubs on the
bottom of the housing to make wiring connections.

An aluminum subpanel is mounted to the interior of the housing. The sample-draw
detector’s internal components are mounted to the subpanel.
