Page 3: System Overview
System Overview The GasVac 311 system is designed to monitor gas levels in situations where the positioning of conventional gas sensors may not be practical. This may be due to equipment security, cable routing, access for detector head installation/maintenance, or harsh environment, or a cost effective means of monitoring plant rooms, supermarkets, cool stores and designated hazardous areas, such as tunnels, marine applications, or underground/high level voids. -
Page 4: Installation, Operation
Installation The unit should be mounted in a position which is accessible and in the field of vision. Mains should be from a fused supply (2A) and connected to the mains input terminals of the power supply unit. The vent port should be piped to atmosphere without reduction. This will prevent possible back pressure affecting the sensor reading. -
