For safety and ease of maintenance, the VOXI should be installed in a non-hazardous-gas
location.*

Extension tubing of up to 100 feet (30 m) can be attached to the inlet to allow remote
mounting if the sampling location contains flammable or toxic gas mixtures.
3.1.2 Mechanical Mounting Options
The VOXI is designed for wall mount or pole mount using the screw-holes provided, centered
5.25 inches or 134 mm apart. If mounted outdoors, ensure that the gas inlet is directed
downwards to minimize the chance of precipitation being drawn into the PID.

Future VOXI versions that have certifications will be able to be installed and operated in hazardous-gas
locations, but because the housing cannot be opened for service in the presence of flammable gases, the VOXI is
easier to maintain if installed in a non-hazardous location or one that can be vented to remove hazardous gases
before opening the housing.
