3.0 Installation

Mounting

The Micro-GASS enclosure is rated NEMA-4 however, the system is intended for indoor

installation. When choosing a mounting location, choose a location that avoids exposure to

direct sunlight as it may raise the internal temperature beyond the system operating limits. The

system should also not be subjected to extremely cold temperatures. Wall mounting of the

system is required for proper operation of the flow meter. A set of four mounting feet are

supplied for mounting the system on 12.4” centers.
