Do not mount the unit near containers of chemicals such as gasoline, kerosene, alcohol,
or other cleaning fluids. High level concentrations of these chemicals may be mistaken
as the target gas by the sensor and cause false readings. Also, some welding gases
may cause false readings.
The transmitter is attached in the mounting position in one of three ways.
•
Attach the housing to conduit using appropriate conduit fittings. If you use this method,
make sure that the conduit is securely attached to a solid support. Firmly tighten the
threaded nuts on the conduit fittings inside the transmitter housing so they will not
loosen over time.
•
Attach the housing to a four inch square conduit box using the ½ inch fitting provided
with the transmitter. Make sure that the conduit box is firmly fastened to the mounting
surface with screws. Securely tighten the fitting nut on the inside of the conduit box so it
will not loosen over time.
•
Attach the housing to a solid support base using screws through the internal housing
mounting holes. This method requires removal of the housing cover to gain access to
the mounting holes. A mounting hole is located at the top and bottom of each housing
end wall.
Find a flat area at least 6 inches high by 6 inches long and place the back of the open
housing flat against it. Using a pencil or other slender marking tool, mark the location of
the four mounting holes using the housing as a template. Start the screws without the
housing in place to avoid any possibility of damage to the housing or circuit boards.
Remove the screws, place the housing in position, and install the mounting screws. Do
not over-tighten the screws as this may crack the plastic housing. Be careful not to
damage the printed circuit board. Carefully replace the housing cover and securely
tighten all four of the cover retaining screws.
Connecting the Power Supply
While this transmitter does not require much power to operate, it is usually located near
machines that do consume large amounts of power. When these large machines operate, they
