Please Read Before Installation
The following will damage the Air Check Oxygen monitor.
1.
The Dual O2/CO2 monitor requires
24 VDC regulated power
.
Please do not connect
the monitor to any voltage that exceeds 24
Volts DC, or
Any AC voltage.
2. Do not power the Dual with the Oxygen sensor or Carbon Dioxide
sensor unplugged from the main PC board.
Do not connect
the O2 or
CO2 sensor to the PC board while the monitor is powered. This Will
Damage the sensors.
3.
The Oxygen sensor cell is matched to the electronics.
Never exchange
the electronics with an Oxygen sensor from a different monitor.
4. When calibrating or challenging the Dual O2/CO2 monitors,
a.
Do not expose the monitor to flow rates that exceed ½ liter per
minute (500 cc per minute) flow.
b.
Expose the monitor to span gas blends that consist of oxygen,
nitrogen or carbon dioxide only.
Do not expose the monitor
to any combustible gas,
i.e., methane, hydrogen, etc.
Exposure to combustible span gases can damage the oxygen
zirconium sensor cell.
5. Do not expose the Dual O2/CO2 monitor to silicone compounds. They
can cause a loss of sensitivity.
6. Do not expose the monitor to high flow air or install it directly in front of
fans. The high air flow can cool the oxygen sensor and cause an inaccurate
reading.
7. When using the Dual O2/CO2 monitor, do not expose the Oxygen sensor
directly to a water stream. In areas requiring wash downs cover and protect the
monitor and power supply. Contact CONCOA for details on a waterproof
enclosure.
8. Please refer to section 6.3 of this manual regarding the CO2 sensor.
YOU MUST
choose a calibration method before use.
