2. Mounting
CautionInstallation site should be examined, giving careful consideration to the following conditions.
Do not touch, drop or place any pressure on the probe.
[This instrument is intended to be used under the following environmental conditions.]• CO2 detectable location and free air flow
• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 ) that does notchange rapidly and no icing• An ambient non-condensing humidity of 5 to 95 %RH• An absence of chlorinated and sulfidizing gases• No large capacity electromagnetic switches or cables through which large current is flowing• No water, oil or chemicals or the vapors of these substances can come into direct contact with the unit
• Enough space for the cover to be removed when maintaining or inspecting• Do not install sensor with the probe in an upward facing position.

Maintenance• Be sure to conduct periodic inspection once within 6 months after installation, then once every year afterthat.
• Change the sensor if 100% or more of deviation from effective range of the standard value criteria(e.g. 400 ppm 150 ppm) occurs.
• Change the sensor if no output occurs.

Do not use this sensor in an environment where dew condensation occurs.
Do not use this sensor in an environment where chlorinated and sulfidizing gases
are being generated.
Temperature: -20 to 60
Humidity: 5 to 95 %RH (non-condensing)[Caution]
Do not apply sustained pressure or shock to the cavity (gold-colored section) whenhandling (installing or storing) the sensor.
If the sensor is exposed to a temperature lower than 0 or higher than (andincluding) 40 for several hours, sensor measurement value will be affected.
If the sensor is stored at high humidity (90% or more) over a long period without
power supplied, the initial measurement value may become slightly high until thehumidity inside the cavity disappears.
