In the event of an alarm, immediately take all necessary
treatment to prevent gas poisoning.
Do not block the gas detection intake in use.
In case liquid spill is happened from the sensor element(by mechanical shock etc.), immediately wash clothes inwater when liquid is adhered.
In case of getting liquid in eyes or ears, immediately
submit to medical treatment after receiving ﬁrst aid bywater.
Be sure to execute daily check and periodic check.
Do not disassemble or modify XC-2200 because it could
cause to lose explosion-proof design.
Use the product in compliance with applicable laws andregulations.
Do not drop or hit the product to avoid intense mechanicalshocks and vibrations. It may aﬀect the functions.
Avoid storing the product or leaving it for a long period oftime in places or car subject to high temperatures andhigh humidity or low temperatures and low humidity.
Do not use the product at outside the operating
temperature/humidity range, and under rapid temperature/humidity change. It may aﬀect the functions.
Keep the product away from exposure to water orcondensation.
In case of condensation, dry completely before using the
product.
Only use speciﬁed battery (Panasonic alkaline AAA
battery LR03X or Toshiba alkaline AAA battery LR03).
The use of unspeciﬁed battery may impair the detectorʼs
explosion-proof performance and product performance.
The sensor may detect other gases (such as hydrogen,NOx, SOx and alcohol); therefore, consider theenvironment when using the product.

) Install the safety pin adaptor on the rearsurface of the product body chassis

4) Gas detection intake
Check that the gas detection intake is not blocked and the ﬁlter element isclean and dry. Replace the element if dirty or wet.
(See “Replacement Parts” on page 5).

（ ） Periodic Check

Check the product accuracy at least once a month and perform gas calibration
at least once every 6 months. It is recommended to contact New Cosmos or
your New Cosmos representative to perform a periodic inspection including
sensor replacement at least once a year (fees apply).
Quick accuracy check can be performed with test jig (EG-105) and gas calibration
can be performed with gas calibration kit (EG-106) by the customer (see page 5).

T his product uses a very small amount of current evenafter turned oﬀ, to stabilize the sensor. Keep the battery in the
product even when the product is not being used.
If the battery is removed from the product for a long period of time,
initial stabilization of the sensor may take longer, causing an error. In
such a case, insert the battery and leave the product with the power
being oﬀ for one day or longer before use.

This product is a precision instrument. Please perform the periodical checks andinspections below to maintain the detectorʼs performance and ensure safety.
In the event of a failure to follow the safety precautions (page 2), such as impact shockfrom dropping or exposure to water, or use in conditions outside the speciﬁcations(page 13), such as usage in temperature/humidity exceeding the speciﬁed range,
please contact New Cosmos or your New Cosmos representative for inspection.

Note

If the TWA concentration (see “Glosary” on page14) exceeds the alarm setting level,"the gas concentration" and "AL. tc" are displayed alternately while the alarm lamp
blinks.
Press the [T x C] switch to cancel the TWA concentration alarm. Note that"gas concentration " and "AL. tc" will continue to be displayed alternately until
the power is turned oﬀ.

（If only the TWA concentration alarm is activated）

Gas detection is ready after air adjustment is complete.

CAUTION● Time Weighted Average (TWA) concentration alarm (for CO only)℃ with no alarm)

mm (excl. projections)approx. g (including battery)

Time weighted average (TWA): Concentration value expressed as the product of gas
exposure time (hour) and gas concentration (ppm).
For this detector, it is calculated by dividing the average
concentration per minute by the integrated value of
60 minutes. Note that there is an error of ±5% in thetime calculation, and the unit is "ppm" just for convenience.
Example: When continuously exposed to 100 ppm CO for
30 minutes, 100 ppm x 30/60 = 50 ppm-h.
Gas calibration:

Adjusting the indicated values by using span gas.
Also called “span adjustment”.

Clean air:

Air free from target or interfering gases, and composedof 20.9-21.0vol% oxygen in dry conditions.
