Important: In Standby Mode, the CleanSpace respirator switches to On Mode as the wearer starts to breathe. The
respirator can only switch into On Mode from Standby Mode. If the respirator is in OFF mode, the motor will not run.
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 respirator is in Standby Mode (not ON Mode), starts the flow test which lasts about 5
seconds. See Section 11 for instructions on running the flow test.
BATTERY INDICATOR LIGHTS
Your respirator is equipped with an indicator of battery charge. There are three (3) battery indicator
lights. With the charger plugged in and three green lights lit, the battery is fully charged and has up to eight (8) hours
of operating time. The respirator should be fully charged before use.
If you need to be sure the battery is 100% charged plug in the charger. Even if the battery is fully charged, the 3
rd
LED will flash for at least three minutes while the respirator checks its condition. Once all 3 LEDs light solidly
without flashing the battery is at 100%.
For how to assess the level of charge, see Section 17.
When the battery approaches a level at which it would not be able to supply the Manufacturer’s Minimum Design
Flow, an alarm sounds (3 beeps, repeated once per second). All green battery lights are extinguished. If the low
battery alarm sounds you must leave the contaminated area immediately and recharge the battery.
Operating time is affected by mask seal, work rate and other factors. The operating times quoted above are
average durations at moderate work rates at sea level. Actual operating times may vary widely from average
durations.
FILTER WARNING ALARM
CleanSpace respirators have a Filter Warning Alarm, which is triggered when the filter is blocked. If
the Filter Warning Alarm sounds (two beeps, repeated once per second) or the Filter Warning
Alarm light comes on, you must leave the contaminated area, and change the filter.
10. Mask Fitting
Before using your respirator you must determine the right mask for your face and know how to adjust the system to
achieve a good fit.
It is vital that your mask is the right size for your face and fits properly. Mask fitting must be carried out by a
specialist / designated mask fitter. The fit must be confirmed by a properly performed fit test. A fit test must be
performed during initial selection of a respirator, or whenever the user’s face changes shape (for instance due to
weight gain or loss) and at least annually.
Qualitative Fit Testing - To perform a qualitative fit test, follow the relevant standard and/or the instructions
provided with the test substance. A qualitative test provides only a PASS/FAIL result, not a fit factor.
Quantitative Fit Testing - See Section 21.
MASK SELECTION GUIDELINES
No set of guidelines can ensure that you have the right size mask for your face. You must confirm the fit
with a fit test. But the tables below will help your mask fitting specialist to select the mask most likely to fit you and
may therefore save time.
