GG-H2-EC
Installation Guidelines:
• Remove enclosure lid to access mounting holes.
• Remove and discard protective cell cap
• Always mount the sensor vertically.
• Must be easily accessible for calibration and
maintenance.
• Mount the sensor close to the potential leak source.
• For optimum detection, mount sensor close to
ceiling (1’ – 3’ below ceiling level).
• Take air movement and ventilation patterns into
account.
• To prevent electrical interference, keep sensor and
wire runs away from mercury vapor lights, variable
speed drives, and radio repeaters.
• Protect sensor from physical damage(forklifts, etc.).
• If mounting on a wall with studs, the mounting
screws should be screwed into the studs.
• Never mount the sensor in CA (controlled
atmosphere) rooms because normal atmospheric
levels of oxygen are required for operation.
• For highly critical locations more than one sensor
should be installed in each room.
• Mount sensor enclosures through the mounting
holes as shown in Figure 1. Use the supplied
self-tapping screws for mounting on sheet metal
surfaces.
