System Maintenance - AIR SYSTEMS INTERNATIONAL BB15 Manuel D'utilisation

1) Make sure all personnel have egressed from the work area.
2) Shut off air source to the box.
3) Remove air pressure from the box by pulling the relief valve ring out.
4) Turn monitor "OFF" at the "ON/OFF/TEST" switch. Do not remove 9-volt batteries. These
are used to maintain a bias voltage to the sensors; this keeps the sensor ready for immediate future use.
5) Disconnect airline hoses.
6) Install dust caps if applicable.
Filter Housing/Bowls: Periodic cleaning of the polycarbonate bowls may become necessary. Remove the
auto drains. Clean the bowls with a mild soapy solution. Reinstall into the filter housing.
Auto Drains: The automatic drains are designed to remove bulk liquid contaminants. The drains (1st & 2nd
stages only) will automatically drain the liquids after the level has reached 1/3 of the bowl capacity. For periodic
cleaning, use a mild soapy solution.
Filter Change: The filtration system consists of a filter change indicator which will gradually change from
green to orange when filter life is spent. (Not available on BB15 series)
Note: Air must be flowing through the filtration unit before the filter change indicators will function.
Drain Lines: Make sure the auto drain tubes are placed in the holes at the bottom of the box to allow the
liquids to drain outside of the box.
Calibration: Monitor calibration should be done monthly or whenever the reading may be questionable. A
calibration date sticker should be affixed for future reference. To obtain an accurate calibration, we recommend
the use of Air Systems' calibration kits.
Part Number:
BBK-20 Calibration kit for CO monitor, 20ppm CO, zero air, regulator and case - 17
liter size.
BBK-10 Canadian Calibration kit for CO monitor, 10ppm CO, zero air, regulator and case - 17
liter size.
BBK-20103 Calibration kit for CO monitor, 20ppm CO, zero air, regulator and case - 103
liter size.
To assure sensor accuracy, calibration of the monitor is required. If you cannot obtain an accurate calibration
sensor replacement may be necessary. Consult Repair Service Department before ordering.
Part Number:
CO-91NS New Replacement Carbon Monoxide Sensor
Battery Replacement: Replace 9-volt batteries when the amber "LOW BATTERY" light illuminates. If the
monitor is not used for 90 days, check the 9-volt battery condition and replace if necessary.
MONITOR BATTERY REPLACEMENT
These batteries continuously provide a required bias voltage to the CO sensor and
power the monitor in the event of AC power loss. If AC and DC power are removed
for a period of 2 hours or more, a 1 hour restabilization period is required on the
sensor as eratic readings may occur.
Batteries approved for use are:
1. Panasonic Industrial Alkaline Battery - 9 VDC Model No. 6AM - 6PI 9V
2. Duracell Alkaline Battery - 9 VDC Model No. MN1604B2
3. Eveready Battery (Energizer) Alkaline 9VDC - Model No. 6LR61-6AM6-9V
