Mask Setup & Troubleshooting Guide

STANDARD MASK GUIDE

What’s in Your Standard Mask Kit:

• Sil­i­cone Mask Body
  
• Neo­prene Headgear
  
• 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.
