Safety Information
Important:
Failure to perform the procedures detailed within this user guide may impair the performance of this
equipment. For maximum safety and optimal performance please read and follow the following
procedures and conditions. The volume flow and quality of the supplied air should be thoroughly tested
at intervals as specified by a competent person after risk assessment.
The WatchGas BAT kit is to be used to test compressed air for; oil mist, water vapor, carbon monoxide
(CO), carbon dioxide (CO2), oxygen (O2), temperature, humidity, flow, pressure and odour in accordance
to your local governing body (see section 2). Gases like NOx, H2S, SO2, NH3, PH3 can be detected with
optionally available gas detector tubes.
The BAT kit should be checked on the correct flow every 6 months. This can only be performed by a
trained and authorized person. How to perform the flow check can be seen in section 10.
Any attempt to repair components or to substitute components can cause error and possible damage
of components. Only replace consumable items (Gas Detector Tubes + WatchGas PDM O2) with genuine
components specified for use as direct replacement for the BAT kit. Use of different components or
attempts to repair components can cause error and possible damage of components.
The quality of the air supplied to a breathing apparatus should be tested at least every three months
and more frequently when the quality of the air supplied cannot be assured.
The regulators and flow restrictors are factory set to deliver the required flow rates specified by the
manufacturers. Flow rates can only be adjusted by trained and authorized personel.
When disposing of old parts always follow local waste disposal regulations.
Additional Warnings concerning the use of the WatchGas PDM O2:
▪
Before operating this device, please read the manual carefully.
▪
If calibration and self test fails continuously, please do not use the device.
▪
For the O
2
detector, perform calibration every 30 days in a fresh air environment, preferably
outside.
▪
Before use, please check the activation date, and if the activation date is past, please do not use
the device. The PDM O2 has a life span of 2 years from start up. A countdown timer shows the
remaining life of the PDM O2. At the end of the PDM O2 life it automatically shuts off. Once the
software shutdown is complete, discard the detector and contact WatchGas for a replacement.
▪
Clean detectors with a soft cloth and do not use chemical substances for cleaning
▪
To maintain 24 months life time, avoid the below activities except the necessary cases to check
events (Max/Min), lifetime/concentration, and alarm set points. Otherwise, the frequent use of
the button will deplete the battery lifetime less than 24 months. Do not push the button
frequently without valid reasons.
*Normal Alarm Use 1 time and 2 minutes per day
▪
View the serial number on the label at the back side of the device.
▪
WARNING: Explosion Hazard - The PDM O2 contains no serviceable parts.
▪
WARNING: Substitution of components may impair intrinsic safety.
▪
WARNING: The PDM O2 contains a lithium battery which may leak or explode if the instrument
is mistreated. Do not attempt to disassemble or dispose of in fire.
▪
Never cover or insert foreign objects into the alarm signal opening, the opening must remain
clear and free of foreign objects, otherwise any alerts made during an alarm state may not be
heard or identified.
