Battery Replacement - Bullard CAB Serie Manual De Usuario

The Red LED on the front of the monitor will continue to blink for approximately 90
seconds during which the calibration process will take place.
Watch for the green LED to blink. This indicates a successful calibration.
With the 10ppm gas still flowing, turn the knob to TEST. The reading should be Co
10+/-1. If any other reading is displayed in the test mode, repeat both the Zero Point
adjustment and CO calibration.
Close the regulator on CO gas cylinder completely and remove the calibration connector
fitting from the center of the knob.
With the incoming air flowing, rotate the knob to the RUN position.
nOTE
Typical calibration takes approximately 90 seconds. If unit will not calibrate
within 3 minutes, repeat the calibration steps with compressed air turned off.
If the problem persists, contact the Bullard Customer Service Department at
1-877-BULLARD (285-5273).
nOTE
Knob must be in RUN position for active monitoring of CO in the air supply.
Shut Down
Make sure all personnel have left the work area.
Shut off the incoming air to the Clean Air Box.
Release air pressure from the box by pulling the relief valve
Turn the CO Monitor off by pressing and holding the ON/OFF button for three seconds.
You will hear three short beeps to let you know the CO monitor is OFF.
Turn the control box switch to the OFF position.
Disconnect the airline hoses.
Install dust caps to prevent entry of debris into the outlet fittings.
System Maintenance
Always depressurize the system before performing service.
Filter Housing/Bowls
Periodic cleaning of the polycarbonate bowls may become necessary. Remove the auto
drains. Clean the bowls with a mild soapy solution. Re-install into the filter housing.
Auto Drains
The automatic drains are designed to remove bulk liquid contaminants. The drains (1st
and 2nd stages only) will automatically drain the liquids after the level has reached 1/3
of the bowl capacity. For periodic cleaning, use mild soap and water.
Filter Change
The filtration system consists of a filter change indicator, which will gradually change
from green to orange when filter life is spent.
nOTE
Air must be flowing through the Clean Air Box 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
liquids to drain outside of the box.

Calibration
Monitor calibration should be performed monthly or whenever the reading may be
questionable. A calibration schedule should be maintained for future reference. To obtain
an accurate calibration, we recommend the use of Bullard calibration kits.

Battery replacement

CO Monitor Battery Replacement: A 9-volt battery is installed under the front panel
cover to provide power
to the CO monitor. This
monitor may also run solely
on DC power if the clean air
box is not attached to an
AC power supply.
To replace the 9-volt
battery, remove the panel
cover from the front of the
Fig. 3
CO monitor. Lift it off from
either the left or right
side. If a 9-volt battery is being used to power the monitor and the battery power
becomes too low, the monitor will indicate
display to indicate it is time to change the battery. (Figure 3)
Optional DC Power Supply:
The CAB Clean Air Box may be operated using 8 AA batteries to provide power to the
external lights, CO alarm and the CO monitor. Lights located on the top of the box will
indicate whether the box is being operated on AC or DC power. If the box is being
powered by DC power (8 AA batteries), the amber light on the top of the box will burn
steady. If the battery power for the box falls below required voltage, the amber light on
top of the box will flash indicating it is time to change the batteries. There will also be an
audible alert in the form of short intermittent beeps that will serve as notification that
the batteries are low. The battery compartment is located on the interior surface of the
Clean Air Box. (Figure 4)
