GG-NH3
Installation Guidelines:
• Remove and discard protective cell label.
• Always mount sensor vertically.
• Locate sensor to be easily accessible for calibration
and maintenance.
• Mount sensor close to potential leak source.
•
Mount sensor in "breathing zone" (4'-5' above floor)
for optimum personnel protection.
• Take air movement and ventilation patterns into
account.
• Keep sensor and wire runs away from mercury
vapor lights, variable speed drives, and radio
repeaters to prevent electrical interference.
• Protect sensor from physical damage (forklifts, etc).
• Mounting screws should be screwed into studs
when mounting on a wall with studs.
• Never mount the sensor in CA (controlled
atmosphere) rooms. Normal atmospheric levels of
oxygen are required for operation.
• More than one sensor should be installed in each
room for highly critical locations.
• Mount sensor enclosure through the mounting
holes as shown in
