STEP 2 – CALIBRATE
This respirator contains a system for synchronising with your breathing and regulating mask pressure. This system
should be re-calibrated if it experiences it experiences a change in temperature of more than 20°C. It is best
practice to also re-calibrate if the unit has been in storage and the storage temperature is unknown.
Steps to re-calibrate:
1.
Remove the filter (and mask if fitted) from the respirator and place the respirator on a stable surface such as a
table.
2.
With the CleanSpace respirator in Standby Mode (i.e. one or more battery indicators lit), press the “Power” and
“Flow Test” buttons on the keypad at the same time.
3.
When both the blue and red LEDs light, release both buttons. Do not touch or move the respirator.
4.
After 5 – 10 seconds the motor will start and will run for 5 – 10 seconds.
5.
When the motor stops, calibration is complete and the battery lights return to indicating battery charge status.
6.
Re-fit the filter.
Important Note: Failure to remove the filter prior to calibration may result in reduced run times. In order to restore
the performance of the respirator, calibration must be performed again with the filter removed.
STEP 3 – TEST FLOW RATE
This test checks that the respirator is able to deliver the Manufacturer’s Minimum Design Flow of 120 litres/minute.
1. Remove the mask if fitted.
Leave the filter in place.
2. Place the respirator flat on a table or other support.
3. Press and release the button marked “Flow Test”.
4. The respirator will automatically run the Flow Test. Note: During the test, the motor will run fast and air will
blow from the left-hand bellows.
5. After 2 seconds the respirator reports the test result using the LEDs on the keypad. Use the table below to
interpret the LEDs.
FAIL (Flow <120 l/min)
Do not use the respirator until a new filter has been fitted and / or battery fully
charged and the test has been repeated with a PASS result.
Reset the respirator by
pressing the Power button. Fully charge the battery and / or replace the filter. Repeat the
flow test. If the respirator fails the test but the filter is new and the battery is fully charged,
contact CleanSpace Technology and do not use until it has been evaluated.
Important: The Flow Test is not a battery charge test. Three LEDs means that, as of the moment it is tested,
the unit can deliver high flow. It does not mean the battery is full. You must check the battery charge
separately. See Section 17.
STEP 4 - DON THE RESPIRATOR
Important: Please read Step 4 all the way through before beginning to don the respirator.
Locate your power unit, mask, neck support and harness. Make sure the mask is the size that you used for your
last successful fit test. Ensure a clean filter is fitted to the power unit.
•
Fit a CleanSpace mask to the power unit
With the peak of the mask upright locate the right-hand mask AirClip (Figure 3). Locate the right-hand power unit
AirClip (Figure 4). It is on the same side of the power unit as the keypad.
