obligation is limited, at BW’s option, to refund of the purchase price, repair, or replacement of a defective product that is returned to a BW authorized service
center within the warranty period. In no event shall BW’s liability hereunder exceed the purchase price actually paid by the buyer for the Product.
This warranty does not include:
a) fuses, disposable batteries or the routine replacement of parts due to the normal wear and tear of the product arising from use;
b) any product which in BW’s opinion, has been misused, altered, neglected or damaged by accident or abnormal conditions of operation, handling or use;
c) any damage or defects attributable to repair of the product by any person other than an authorized dealer, or the installation of unapproved parts on the
product; or
The obligations set forth in this warranty are conditional on:
a) proper storage, installation, calibration, use, maintenance and compliance with the product manual instructions and any other applicable
recommendations of BW;
b) the buyer promptly notifying BW of any defect and, if required, promptly making the product available for correction. No goods shall be returned to BW
until receipt by the buyer of shipping instructions from BW; and
c) the right of BW to require that the buyer provide proof of purchase such as the original invoice, bill of sale or packing slip to establish that the product is
within the warranty period.
THE BUYER AGREES THAT THIS WARRANTY IS THE BUYER’S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL OTHER WARRANTIES,
EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE. BW SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING
LOSS OF DATA, WHETHER ARISING FROM BREACH OF WARRANTY OR BASED ON CONTRACT, TORT OR RELIANCE OR ANY OTHER THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or limitation of incidental or consequential damages, the
limitations and exclusions of this warranty may not apply to every buyer. If any provision of this warranty is held invalid or unenforceable by a court of competent
jurisdiction, such holding will not affect the validity or enforceability of any other provision.

GasAlertMicro
Introduction
aWarning
To ensure your personal safety, read “Safety
Information” before using the detector.
The GasAlertMicro gas detector (“the detector”) is designed
to warn of hazardous gas at levels above user-selectable
alarm setpoints.
The detector is a personal safety device. It is your
responsibility to respond properly to the alarm.
Table 1 lists the gases that are monitored.
Table 1. Gases Monitored
Gas Detected Unit of Measure
Hydrogen sulfide (H2S) parts per million (ppm)
Carbon monoxide (CO) parts per million (ppm)
Oxygen (O2) percent by volume (%)
Combustible gases
field selectable for:
a) percent of lower
explosive limit (% LEL)
b) percent by volume

Safety Information - Read First
Use the detector only as specified in this manual otherwise
the protection provided by the detector may be impaired.
International symbols used on the detector and in this
manual are explained in Table 2.
Read the Warnings and Cautions on the following pages
before using the detector.
ecNote
This instrument contains batteries. Do not mix
with the solid waste stream. Spent batteries
should be disposed of by a qualified recycler or
hazardous materials handler.

GasAlertMicro
Safety Information - Read First
aCautions
⇒Warning: Substitution of components may impair Intrinsic Safety.
⇒Do not use the detector if it is damaged. Inspect the case before use. Look for cracks and missing parts.
⇒If the detector is damaged or parts are missing, contact BW Technologies immediately.
⇒Ensure the battery compartment is locked in place before operating the detector.
⇒Use only a sensor that is specifically designed for the GasAlertMicro model. Refer to Replacement Parts and
Accessories.
⇒Calibrate the detector before first-time use and continue on a regular schedule. The schedule will depend upon
use and sensor exposure to poisons and contaminants. BW recommends that calibration be performed a
minimum of once every 180 days (6 months).
⇒BW recommends to “bump test” the sensors, before each day’s use, to confirm their ability to respond to gas
by exposing the detector to a gas concentration that exceeds the high alarm setpoints. Manually verify that the
audible and visual alarms are activated. Calibrate if the readings are not within the specified limits.
⇒BW recommends that the combustible sensor be checked with a known concentration of calibration gas after
any known exposure to catalyst contaminants/poisons (sulfur compounds, silicon vapors, halogenated
compounds, etc.).
⇒The combustible sensor is factory calibrated to 50% LEL methane. If monitoring a different combustible gas in
the % LEL range, calibrate the sensor using the selected gas. High off-scale % LEL or % v/v methane readings
may indicate an explosive concentration.
⇒Protect the combustible sensor from exposure to lead compounds, silicones, and chlorinated hydrocarbons.
Selected organic vapors (ie. leaded gasoline and halogenated hydrocarbons) may temporarily inhibit sensor
performance. However, in most cases the sensor will recover after calibration.

GasAlertMicro
User Manual
aCautions (cont.)
⇒Any rapid up-scaling reading that is followed by a declining or erratic reading can indicate a gas concentration
beyond upper scale limit. It may be hazardous!
⇒Use only recommended AA alkaline or NiMH batteries that are properly charged and installed in the detector
case. Refer to Replacement Parts and Accessories.
⇒Charge NiMH batteries using the recommended charger only. Do not use any other charger. Failure to observe
this precaution can lead to fire or explosion.
⇒Do not change or charge batteries in a hazardous location. Doing so will impair the Intrinsic Safety of the unit
and can lead to fire or explosion.
⇒Read and observe all instructions and precautions that are provided with the charger. Failure to do so can
result in fire, electric shock, or other forms of personal injury and property damage.
⇒Extended exposure of the GasAlertMicro to high concentrations of combustible gases and air may stress a
detector element, which can seriously affect its performance. If an alarm occurs due to high concentration of
combustible gases, recalibrate immediately. If required, replace the sensor.
⇒Do not test the combustible sensor response with a butane cigarette lighter. This will damage the sensor.
⇒Do not expose the detector to electrical shock or severe mechanical shock.
⇒Do not attempt to disassemble, adjust, or service the detector unless instructions in the User Manual are
provided to perform a procedure, or if a part is listed as a replacement part. Use only BW Technologies
replacement parts.
⇒Do not immerse the detector in liquids.
⇒The detector Warranty will be voided if a customer, personnel, or third parties damage the detector during
repair attempts. Any Non-BW Technologies repair/service attempts will void this Warranty.
