-4- BREATHING AIR QUALITY POSITION STATEMENT The responsibility for the quality of breathing air rests with the user. Compliance with federal, state, or local regulations are the responsibility of the user and this recommendation does not supersede any existing rules, regulations, or laws which may apply. Breathing air filtration products meet or exceed CGA Grade-D specifications for air quality as adopted by Federal OSHA. Compressor air quality standards meet or exceed OSHA 1910.134 requirements.
-5- MONITOR OVERVIEW The monitor will analyze the air sample and display the CO concentration 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).

-7- BREATHER BOX TM SETUP AND OPERATION Note: Always operate the Breather BoxTM in the upright position. Failure to comply may result in one or all of the following: • 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.

All local and remote audible/visual indicators will activate.
-9- SHUTDOWN 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.
-10- SENSOR REPLACEMENT Replacement sensors are shipped with a metal spring installed between the electrodes. Do not remove the clip until the sensor is to be installed into the monitor. STEP 1) Disconnect all external connections. Remove CO monitor from the unit. STEP 2) STEP 3) Remove the four screws from the monitor’s Remove end plate to gain access left end plate. to the sensor cup from outside the Note: Alarm location may vary. housing. STEP 4) Remove sensor from sensor cup and remove leads .
-11- CALIBRATION PROCEDURE Do not use inert gases to zero the monitor. This will cause premature failure of the sensor. CO Zero Adjustment To zero the instrument, follow the steps below. Zero calibration gas should be used to properly “zero” the instrument and assure that a valid calibration is achieved. If zero adjustment cannot be made as indicated, sensor replacement may be necessary. After each monitor adjustment outlined in the following steps, allow time for the changes to stabilize. 1.
-12- CO SPAN ADJUSTMENT Use only 10 - 20 ppm CO gas for calibration. Using a higher concentration may decrease accuracy at lower scale readings. Note: 10ppm gas must be used to satisfy Canadian calibration requirements. 1. Install regulator to the CO calibration gas cylinder. 5. Adjust the "span" pot adjustment screw (clockwise to increase, counterclockwise to decrease) until the digital display reads the same concentration (ppm) as printed on the calibration gas cylinder. 2.
