SPECIAL WARNINGS
Through engineering, design and testing as well as rigid manufacturing techniques
and quality control, BW Technologies supplies the finest gas detection instrumentation
available. The BW DEFENDER is designed to provide optimum performance and
lower maintenance in rugged industrial use. The user, though, must recognize
responsibility for maintaining the instrument in operational condition, ensuring proper
operation and long-term use.
1. Calibrate the detector before first-time use, and then at least once every 90 days.
2. It is recommended that the accuracy of the BW Defender be checked with known
concentration calibration gas before each day’s use and immediately after any
know exposure to contaminants.
3. The LEL sensor is factory calibrated to methane. If monitoring a different
combustible gas, calibrate the sensor using the appropriate gas.
4. BW recommends that a calibration check on a regular schedule, one at least
every 30 days.
5. Do not expose BW DEFENDER to electrical shock and/or severe continuous
mechanical shock.
6. Do not attach any other piece of equipment to the BW DEFENDER except those
supplied by BW for the BW DEFENDER.
7. Do not operate or attempt to modify the BW DEFENDER to operate on any
battery or power source except the battery approved by BW Technologies.
8. Do not attempt to disassemble, adjust or service the instrument unless
instructions are contained in the manual for that procedure and/or that part is
listed as a replaceable part. Use only BW DEFENDER replaceable parts.
9. Do not immerse in liquid OR use high power sprays on the instrument.
10. Do not allow the sensor screens to become dirty or clogged.
11. BW Technologies gas detection instruments are primarily SAFETY devices for
the protection of personnel and facilities and must always be “ready”. With proper
maintenance the BW DEFENDER will provide many years of service. The user
must assume all liability for misuse of BW Technologies gas detection
instruments.
12. The instruments warranty will be voided if customer personnel or third parties
damage the instrumentation during repair attempts.
Because BW Technologies is constantly developing and improving its products line,
we reserve the right to change specifications without notice.
