• Auto drains will not function properly. This may result in the contamination of the CO monitor and cause water to be passed
through respirator hose and into the worker's mask.
• Auto drains may become clogged, clean or replace auto drains (See Maintenance Instructions.)
• Filters may accumulate moisture and/or contamination, replace if necessary.
STEP 1)
Secure a primary air source of sufficient air flow and discharge pressure.
The number and type of respirators being used determines the flow rate
and pressure required.
STEP 2)
Check airline monitor for fresh 9-volt batteries and turn the unit on. Connect the
remote signal cable, 115 VAC plug, and air sample hose to the monitor. Note:
Remote signal cable does not apply to BB15 series. Place the "ON/OFF/
TEST" switch to the "ON" position. Allow 30 seconds for the readout to
stabilize. If a reading other than "ZERO" is displayed, calibration of the monitor
may be necessary. See calibration procedure.
STEP 3)
Connect the extension cord to a 115 VAC receptacle. Note: The CO
monitor can run off the twin 9-volt batteries if no AC power is available.
STEP 4)
Connect the remote alarm assembly (optional) to the remote alarm jack.
Note: Does not apply to BB15 series.
STEP 5)
