STEP 7)
Hold the "ON/OFF/TEST" switch in the "TEST" position. All local and
remote audible/visual indicators will activate. If indicators do not acti-
vate, check all electrical connections, then call factory repair department.
Note: An alarm function test can be performed at any time by lifting the
"ON/OFF/TEST" switch to the "TEST" position.
STEP 8)
Attach the desired respirators and lengths of hose to the quick connect
outlet couplings. Note: Some models may not have respirator connec-
tions. They can be ordered with NPT outlets for connection to points of
attachment.
STEP 9)
Adjust the outlet pressure to the setting recommended by the respirator
manufacturer. Turn the knob clockwise to increase pressure, counterclock-
wise to decrease pressure.
STEP 10)
Adjust CO monitor air sample flow rate by turning the flowmeter control
knob counterclockwise until the float hovers in the green bar area
(approximatley 50-100 cc/min). The box is now ready for operation.
The instrument will analyze the air sample and display the CO concen-
tration in parts-per-million (ppm). The system's green "NORMAL"
operation light will illuminate, and the red "HIGH CO" light will flicker
faintly approximately every second when the CO level is below 10ppm
(5ppm Canadian).
When the CO concentration level exceeds the alarm set point, the green
"NORMAL" light will turn off, the red "HIGH CO" light illuminates,
the audible alarm will sound, and the remote alarm connections will
energize.
When CO concentrations drop below the alarm set point, all alarm
indicators will deactivate, and return to "NORMAL" operation.
