• Infla­tion Syringe
  
• Blue Valve Ring

Inflate the Mask & Proper Face Placement

How to Inflate the Cush­ion & Fit the Mask:

1. 1. Use the syringe to draw in air.
   
2. 2. Insert it into the small port on top of the mask.
   
3. 3. Inflate until the cush­ion is about ⅔ full — it should feel soft but cre­ate a gen­tle seal.
   
4. 4. If the mask feels too tight or bulging, remove some air with the syringe.
   
5. 5. Cen­ter the mask over your face — it should cov­er your nose and mouth with­out block­ing your vision.
   
6. 6. If the mask sits too high, it may restrict nasal breath­ing.
   
7. 7. If it sits too low, you may feel air leak­ing.
   
8. 8. Adjust until it feels snug, bal­anced, and sealed with no pres­sure points.

Diagnosing and Fixing Valve Issues

How to Check the Inter­nal Valves:

1. 1. Look inside the mask and find the two teal-col­ored sep­tum valves.
   
2. 2. They should lie flat and move gen­tly as you breathe in and out.
   
3. 3. If air­flow feels blocked, inspect for any fold­ing or mis­align­ment.
   
4. 4. Re-seat them if need­ed and con­firm smooth air­flow.

Strap Fitting & Common Slip Fixes

How to Fit and Secure the Headgear:

1. 1. Slide the neo­prene strap sys­tem over the mask body.
   
2. 2. Align the holes with the ports and anchor points.
   
3. 3. Posi­tion the rear strap low on the back of your head — near the base of your skull.
   
4. 4. Adjust the strap ten­sion until the mask stays in place com­fort­ably dur­ing move­ment.
   
5. 5. If the mask slips dur­ing train­ing, check for hair or sweat under the strap and adjust as need­ed.

Mask Seal Check – Suction Test

How to Per­form the Suc­tion Test:

1. 1. Cov­er the inlet port on the mask with your hand.
   
2. 2. Inhale gen­tly.
   
3. 3. You should feel the mask pull inward slight­ly against your face.
   
4. 4. When you remove your hand at peak inhale, you should hear a light “whoosh” of air. 
   • This con­firms that the mask is form­ing a good seal.
