Limited Warranty & Limitation of Liability
BW Technologies Ltd. (BW) warrants this product to be free from defects in material and workmanship under normal use and service for a period of two years,
beginning on the date of shipment to the buyer. This warranty extends only to the sale of new and unused products to the original buyer. BW’s warranty
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.

Introduction
a Warning
To ensure your personal safety, read “Safety
Information” before you use the detector.
The GasAlertMicro gas detector (“the detector”) warns of
hazardous gas at levels above user-selectable alarm
setpoints. This product is a gas detector.
The detector is a personal safety device. It is your
responsibility to respond properly to the alarm.
Table 1 lists the gases monitored.

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.
ec Note
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.
2
GasAlertMicro
Safety Information - Read First
a Cautions
⇒ Warning: Substitution of components may impair Intrinsic Safety.
⇒ Do not use the detector if it is damaged. Before you use the detector, inspect the case. Look for cracks or missing
parts.
⇒ If the detector is damaged or something is missing, contact BW Technologies immediately. See “Contacting BW
Technologies”.
⇒ Make sure the battery holder is locked in place before you operate the detector.
⇒ Use only a sensor specifically designed for your GasAlertMicro model. (See the section “Replacement Parts and
Accessories.”)
⇒ Calibrate the detector before first-time use and then on a regular schedule, depending on use and sensor
exposure to poisons and contaminants. BW recommends at least 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.
⇒ It is recommended 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.).
3
GasAlertMicro
Users Manual
a Cautions (cont.)
⇒ 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 appropriate 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.
Although certain organic vapors (such as leaded gasoline and halogenated hydrocarbons) may temporarily inhibit
sensor performance, in most cases, the sensor will recover after calibration.
⇒ Any rapid up-scaling reading followed by a declining or erratic reading may indicate a gas concentration beyond
upper scale limit, which may be hazardous.
⇒ Use only recommended AA alkaline or NiMH batteries properly charged, and installed in the detector case. (See
the section “Replacement Parts and Accessories.”)
⇒ Charge NiMH batteries using recommended charger only. Do not use any other charger. Failure to observe this
precaution could 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
may lead to fire or explosion.
⇒ Read and observe all instructions and precautions in the literature provided with the charger. Failure to do so may
result in fire, electric shock or other forms of personal injury or property damage.
4
GasAlertMicro
Safety Information - Read First
a Cautions (cont.)
⇒ Extended exposure of the GasAlertMicro to certain 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, recalibration should be performed, or if needed, the sensor replaced.
⇒ Do not test the combustible sensor’s response with a butane cigarette lighter; doing so will damage the sensor.
⇒ Do not expose the detector to electrical shock and/or severe continuous mechanical shock.
⇒ Do not attempt to disassemble, adjust or service the detector unless instructions for that procedure are contained
in the manual and/or that 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 customer, personnel or third parties damage the detector during repair
attempts. Non-BW Technologies repair/service attempts void this Warranty.
