Chapter 3. MOUNTING AND WIRING
WARNING
When using combustible gas, install the device upstream of the safety shut
off valve. If air somehow enters the piping, and the sensor makes a spark due
to some cause like a lightning strike when an explosive mixture is present, an
explosion could occur inside the pipe.
On flanged models, do not use the device or installed pipes as a footrest.
Doing so might damage the device or piping, or cause a slip which might
result in injury.
Flanged models are heavy. Dropping them on your feet may cause injury.
Handling Precautions
• When carrying the device, hold it by the flow path section.
Holding it by the sensor/terminal section may damage the device.
• This device is a precision instrument. Do not drop it or subject it to
shock. Doing so might damage the device.
• If the CMG model has a threaded pipe connection, when
connecting the piping fasten the flow inlet/outlet section, and
then screw in the pipe side to connect the piping.
• When connecting a flanged device, first check that the piping is
not tilted or off center before installing. Failure to do so might
cause leakage.
• To prevent vibration of the device, attach the pipe securely.
• Do not peel the protective seals from the display before use. When
performing work on the device, tools may accidentally bump
against the display and scratch it.
• When using the device outdoors, mount it out of the direct
sunlight and in a location where it is not splashed directly by rain.
• If the piping may contain rust, oil mist, dust, or powder, be sure
to provide a strainer or filter upstream to prevent foreign matter
from entering the device. Foreign matter flowing into the device
might result in faulty operation.
• When wiring the device, take care not to tug on the display. The
internal connections might become damaged.
