Airflow Test with Airflow
Indicator
With the turbo-blower unit turned ON,
breathing tube connected to turbo-
blower unit, and the filter / cartridge
installed, place the upright- positioned
Airflow Indicator onto the free end of the
breathing tube.
If the Airflow Indicator “Bottom of the
Ball” fails to rise completely above the Top
EVA “Pass Line” on the Airflow Indicator
Tube, then the turbo-blower unit could
be malfunctioning, have a clogged or
damaged filter / cartridge, low battery, or
battery malfunction.
Do not use a turbo-blower unit that fails
the airflow test. Failure to observe this
warning could result in death or serious
injury.
Ensure the air outlet holes in the Airflow
Indicator are not blocked by your hand,
or other obstructions during the Airflow
Test. Any hole blockage will give bad air
flow results.
Confirm the ball, within the Airflow
Indicator, moves freely in the tube and
rests at the bottom of the tube when
turned upright before testing begins.
Airflow indicator must be in an upright,
vertical position for an accurate
measurement during the entire testing.
Low Flow Alarm
It is important to follow these steps to test the turbo-blower unit Low Flow
Alarm prior to operation.
1. Install battery, filter / cartridge, and breathing tube on turbo-blower unit
according to section Setup and
Getting Started.
2. Press and hold the button for two
(2) seconds, confirmed by a short
beep, to turn the turbo-blower ON.
3. Cover the outlet end of the
breathing tube with your hand to
completely cut off airflow.
4. With the breathing tube blocked,
the turbo-blower unit will increase
in speed for approximately 15
seconds until it sounds the Low
Flow Alarm. Refer to section Understanding Alarms.
Cleaning, Storage, and Disposal
The EVA Powered Air-Purifying Respirator (PAPR) system should be cleaned
and inspected after each use and prior to storage. Detach the battery,
breathing tube, and hood from the turbo-blower unit. Inspect all parts for
damage or other signs of excessive wear. Replace all damaged parts prior to
storage or next use.
