3. Operating Instructions (continued)
FLOW TEST BUTTON
This button is used to check that the respirator is able to deliver its minimum designed flow.
Pressing it once, when the CleanSpace Respirator is in Standby Mode (not ON Mode), starts the
flow test which lasts about 5 seconds. See Section 4 for instructions on running the flow test.
PRESSURE SENSOR AUTO & MANUAL ZERO CALIBRATION FUNCTION
™
The CleanSpace2
Respirator has a pressure sensor zero calibration function to ensure accurate positive
pressure regulation inside the mask. When there is a variation in the ambient temperature of greater than 20°C
between uses (for example, a variation from -10°C to 10° C), the CleanSpace2
should be zero calibrated before use. This can be done in two (2) ways:
1. Auto-Zero Calibration To auto-zero calibrate the pressure sensor, switch the Respirator into Standby Mode
for at least 20 seconds before use.
2. Manual-Zero Calibration Switch the Respirator into Standby Mode. A manual-zero calibration can be
performed by pressing the Power Button and Comfort Airflow Button at the same time. The Buttons should be
held until both the Blue and Red lights are on, after which the Buttons should be released. The lights will stay on
for a few seconds while the Respirator recalibrates. The calibration is completed when the blue and red lights
switch off.
4. Fitting and Removing CleanSpace2
STEP 1: PREPARATION FOR USE
™
Check the CleanSpace2
Respirator is complete and undamaged. If there are any damaged or defective parts, the
Respirator should not be used.
™
Note: The CleanSpace2
Power Unit does not come with a mask. The mask assembly is sold separately and is
available in three (3) sizes (small, medium and large). You will need to purchase and fit a CleanSpace
assembly before using the CleanSpace2
Before use, follow the procedures below:
•
Unclip and release the filter cover to check there is a filter in place.
•
Check that the battery is charged by pressing the power button. We recommend that a minimum of 2
green lights be lit before use. At this level of charge, the Respirator has between 25% and 75%
charge and will typically operate for between 2 and 4 hours. If the battery needs charging, charge the
Respirator for at least 2 hours before use.
•
Check the mask to ensure that there are no cracks, tears or dirt; check the mask is not distorted.
•
Remove the exhalation valve cover and check the exhalation valve thoroughly for cracks, tears and
dirt. Remove any dirt, hairs or anything that could affect the seal of the valve against its seat. Replace
the valve if cracked or torn. Replace the valve cap.
•
If being used, check the harness is intact and has good elasticity.
Flow Rate Test
CleanSpace2 can be tested to check its flow performance against the Manufacturer's Minimum Design Flow
(MMDF) of 120 litre/minute. We recommend that this test is run before each use.
