Introduction
Thank you for selecting the Bullard AirGuard. The AirGuard is a portable grade D breathing air system which meets
NFPA and OSHA requirements. It uses a three-stage filter system which removes oil, water, particulate matter and
odors from the air stream. The AirGuard reports both Carbon Monoxide and differential dew point values on a
visible and externally mounted liquid crystal display. It also has operator warning alarms for flow (CFM) and
calibration interval reminders. The AirGuard data log records all operational use and calibration events for OHSA
compliance reporting.
Safety Recommendations
Important Reference Information
Note = Important information about use of the instrument.
Remarque = Informations importantes sur l'utilisation de l'instrument.
Caution = Affects Equipment – If not followed may cause damage to the instrument or
sensor.
Attention = affecte l'équipement - s'il n'est pas suivi, il peut endommager l'instrument
ou le capteur.
Warning = Affects personal safety – If not followed may cause bodily injury or death.
Avertissement = Affecte sécurité personnelle - non suivi peut causer des blessures
corporelles ou la mort.
General Safe Use Considerations
AirGuard is an instrument designed for Grade D breathing air compliance. It is
important that the operator is trained by qualified personnel to ensure proper
use.
The AirGuard is approved primarily for indoor locations and limited outdoor use.
Do not use the AirGuard unless you have been trained to operate the instrument
and fully understand its implementation as a health and safety device.
Inappropriate use can result in severe injury or death.
Observe Proper Battery Maintenance and use only chargers supplied by
BULLARD to avoid battery damage.
Do not recharge AirGuard in a hazardous classified or environmental location.
Indoor recharging only.
Perform a bump check before each use. Adjust the calibration if necessary.

After airflow is connected, check the 0.01 micron filter for a fault indication. This is displayed by observing the
bubble indicator on the top of the middle valve filter assembly when AirGuard is supplied with compressor air.
Should AirGuard at any time experience server shock or impact recheck the calibration via a bump check and
adjust if necessary.
Always have a trained and qualified person to interpret the values to ensure safe operation.

General Software Interface
AirGuard uses a computer control menu interface which communicates using an LCD. Three buttons control this
interface. These buttons toggle the menu function selection, allow the adjustment of numeric values, and enter
commands.
This three-button interface is located directly under the LCD. The buttons are color-coded, (left) red cursor up,
(middle) green enter and (right) orange cursor down. Additionally, the up-down buttons have a droplet point for
direction to assist function direction.
The main menu has three menu icons that allow access to menu functions and operational changes. From the
primary display, these icons are accessed by using the up/down buttons. The active icon selection has a black
border while the other icons will be grey. The default position is located on the check icon. Toggling the buttons
down or up will change the icon selected position. Upon selection of the desired function, press the middle green
enter button to enter the function.

Menu Function Interface Overview
Upon powering on, the AirGuard will display a warmup screen and then “AirGuard Status” screen which
communicates the status of 5 monitored functions.
1. CO Concentration Alarm
2. Calibration Interval Day Count Down
3. CFM Flow Alarm
4. Dew Point Sensor Operation
5. Air Flow to the CO Sensor
This icon has three status functions as defined below.
1. Green Check = System Operation Satisfactory
2. Yellow Check = System Caution or Warning to which user attention is required.
3. Red “X’ = System Fault - AirGuard requires immediate calibration or service and must not be used until
the issue reported is resolved.
Should the status of the AirGuard change during operation, the AirGuard will change the green check symbol along
with the display background if applicable. When the check symbol changes color, the operator can press the enter
button to display the AirGuard Status screen which will show the warning or fault encountered.
The alarms can be disabled by selecting the disable function during an activation event.
To get to the main display, the operator must toggle to the exit function to display the main operational screen as
illustrated below.
