Gas Monitors should be installed where gas leaks are expected.
The installed location depends on the density of the gas being monitored, higher for
gases lighter than air and lower for gases heavier than air. The display on the front
of the instrument must always be clearly visible and have an unobstructed view.
Before beginning the installation, with the help of the shipping
documents and the sticker on the shipment carton, check that the
delivered components are complete and correct.

Gas Monitors must be installed with the toxic, oxygen or
combustible catalytic sensor inlet points downwards to avoid clogging of the
gas inlet by particles or liquids. Infrared combustible gas sensors must be
installed with the sensor horizontal to prevent accumulation of dirt or
moisture on the optics.

Gas Monitors must not be painted.
When painting, always make sure that no paint falls on the sensor inlet
fitting. Paint deposits can prevent the gas diffusion process where gas from
the atmosphere diffuses into the sensor. In addition, any solvents in the paint
may activate the alarm.
