
Locate CS3029 Seal Check Cap BIO, which is a red rubber cap. Fit the cap over the mask BIO
Exhalation Valve Cover and push until it snaps into place.

The Cap blocks the exhalation valve and will lead to build-up of Carbon Dioxide in the mask. Never leave
the Cap in place for more than 2 minutes!

Check that no air is flowing from the exhalation valve. Breathe normally.

Using your fingers (and reaching up inside the Head Cover) feel around the perimeter of the mask for
leaks. You will feel any leak as a cool flow of air over your finger. For greater sensitivity breathe out firmly
to raise the mask pressure. Wetting your fingers will make it easier to feel tiny leaks.
 If necessary, tighten the mask. To tighten the mask, place one hand against the back of the blower and
the other over the front of the mask. Push the blower forwards and the mask back, tightening the fit. You
will hear a series of clicks as the mask is tightened.

Be careful to tighten each side by the same amount.
 After each tightening, feel for leaks again.
 Tilt your head down (look at the ground) and up (look at the sky). Check that there are still no leaks. Look
right and left, checking for leaks. Adjust if necessary.

Once you can feel no leaks from the mask, the seal check is complete.
WARNING
IF A SATISFACTORY SEAL CHECK CANNOT BE ACHIEVED, DO NOT ENTER THE CONTAMINATED
ZONE.
 Remove the Seal Check Cap by pulling on the flange around its base. Failure to remove the cap will lead
to build-up of Carbon Dioxide in the mask and may result in headache or dizziness.
WARNING
DO NOT LEAVE THE SEAL CHECK CAP IN PLACE FOR MORE THAN 2 MINUTES.
STEP 2 – FIT THE EXHALATION FILTER

If you are using CS3027 Exhalation Filter, fit it now by pressing it onto the BIO Exhalation Valve Cover
until you hear a “click”. If necessary, support the BIO Exhalation Valve Cover by reaching up inside the
Head Cover.
15. Using CleanSpace HALO with Full Face Masks
Complete the following six steps each time you use your respirator with a full face mask.
STEP 1 - INSPECT
Before each entry into a contaminated area, the following inspections must be performed:

Visually check the entire respirator system including the blower, mask, harness and filter. If parts are
missing or damaged replace them only with approved parts before proceeding. Check the top and
bottom case of the blower for cracks or other damage. Do not use the device if there is any damage.
