WARNING
If this device is used with flammable gases such as natural gas,
propane or butane, mount it on the upstream side of the safety shutoff
valve.
When air gets in the pipe and an explosive mixture is produced, and if a
sensor should make a spark due to lightning or other reasons, the mix-
ture may explode inside the pipe.
The mass of this device is 7 to 23kg according to the model number.
Ensure to take complete precautions and care while handling for trans-
portation or installation. For safe handling, two or more persons are
required while handling this device.
Accidental dropping of the device on the foot might cause injury.
Do not hold the device by the converter alone. Doing so might damage
the device, or the pipe connector section may drop off.
Do not use this device or its installed pipes as a scaffolding.
Doing so might damage the device or the pipe, or might cause physical
injury.
Do not disassemble this device.
If it is disassembled when pressure remains in the pipes, the device
could be damaged or someone could be injured by flying parts.
CAUTION
Be sure that the operating gas temperature does not fall below -15°C.
Using the gas below -15°C, the O-ring might crack and cause gas leak-
age.
Prevent foreign matter from entering the device.
If the rust, water droplet, oil mist or dust in the piping flows into the
device, measurement error might occur and result in damaging the
device.
If there is a possibility that any foreign matter flows into the device,
provide a filter, strainer or mist trap capable of eliminating more than
1µm foreign matter at the upstream, and periodically inspect and
replace the filter.
If this device is used for monitoring flowrate of the burner, consider the
piping instrumentation lest the backfire damage this device.
When connecting the load to the output terminals, do not exceed the
rated value shown in the specifications.
Doing so might cause the damage of this device.
