SAFETY SUMMARY  
SAFETY SUMMARY  
To ensure the safe and proper installation and use of the  
Invacare Twilight Nasal Mask and Headgear, these  
instructions MUST be followed:  
WARNING  
This Twilight Nasal Mask should be used only with  
CPAP systems recommended by your physician or  
respiratory therapist. A mask should not be used unless  
the CPAP system is turned on and operating properly.  
NEVER block the vent hole or holes associated with  
the mask.  
Explanation of Warning: CPAP systems are intended  
to be used with special masks with connectors which  
have vent holes to allow continuous flow of air out of  
the mask. When the CPAP machine is turned on and  
functioning properly, new air from the CPAP machine  
flushes the exhaled air out through the attached mask  
exhalation port. However, when the CPAP machine is  
not operating, not enough fresh air is provided through  
the mask, and exhaled air may be rebreathed.  
Rebreathing of exhaled air for longer than several  
minutes can in some circumstances lead to suffocation.  
This warning applies to most models of CPAP systems.  
The entire mask system is for single patient use, and  
must not be reused on another person. This is to avoid  
risk of cross-infection.

HEADGEAR/MASK ASSEMBLY, PLACEMENT  
HEADGEAR/MASK ASSEMBLY, PLACEMENT  
AND USAGE (FIGURE 1)  
NOTE: Wash the headgear before using it for the first time, as dye may  
run. Refer to CLEANING THE MASK AND HEADGEAR in this manual.  
NOTE: Invacare recommends washing your face before fitting the  
mask. This will remove excess facial oil and extend the life of the mask.  
1. Check the nasal mask, ensuring that the nasal cushion is attached,  
the swivels function, and the exhalation ports are clear.  
2. Attach the headgear to the nasal mask by sliding the upper  
headgear straps through the loophole of the forehead support.  
3. Adjust each strap by folding it back and attaching it to itself,  
using the hook and loop fastener straps.  
4. Slide the lower headgear strap through the loopholes of the  
headgear clips.  
5. Loosely secure the straps by folding them back and using the  
hook and loop fastener straps.  
6. Connect a standard 22mm bore, 6-foot tube from your flow  
generator to the tubing swivel by pressing the tube end over  
the swivel.  
7. Turn ON the flow generator BEFORE placing the mask on  
your face.  
8. Place mask on face with headgear straps behind head.  
9. Adjust the mask position on the nose. Depress the forehead  
support adjustment tab and slide the forehead support up or  
down until it contacts the forehead and the upper portion of the  
nasal cushion lightly touches the bridge of the nose. The mask  
should fit comfortably.  
10. Place the mask loosely over the nose, with minimal pressure.  
11. Attach the headgear clips to the nasal mask.  
NOTE: If a leak occurs, tighten the headgear straps by readjusting the  
hook and loop fasteners.  
WARNING  
DO NOT pull the straps too tight, this can cause skin  
irritation and may deform the nasal cushion, causing a leak.  
If the mask and headgear are adjusted correctly and a  
problem persists, contact your healthcare professional.

MASK REMOVAL, DISASSEMBLY AND CLEANING  
WARNING  
DO NOT expose any part of the mask system or tubing  
to direct sunlight, as it may cause mask deterioration.  
After cleaning, ALWAYS rinse mask thoroughly. Insuffi-  
cient rinsing of cleaning agents can result in severe skin  
rash, irritation and skin breakdown.  
Wash the entire mask system (except the headgear) after each use.  
Wash the headgear at least once per week.  
NOTE: ALWAYS hand wash the headgear to increase the life of the  
product.  
1. Separate the headgear from the mask assembly and hand wash the  
mask components using a mild detergent (such as dishwashing  
detergent) in warm water. Rinse thoroughly and allow parts to  
air-dry out of direct sunlight.  
NOTE: It is not necessary to remove the nasal cushion after every use.  
It can be cleaned and rinsed while it is mounted to the mask shell.  
DISASSEMBLING/REASSEMBLING THE NASAL  
CUSHION TO THE MASK SHELL (FIGURE 3)  
1. Remove the nasal cushion by slowly pulling it out of the nasal  
mask channel. Refer to FIGURE 3.  
2. Hand wash the nasal cushion using a mild detergent (such as  
dishwashing detergent) in warm water.  
3. Prior to rinsing, press the ribbed portion of the nasal cushion  
into the channel of the mask shell.  
NOTE: Wetting the cushion ribbing sparingly with soapy water will ease  
the insertion into the nasal channel.  
4. Start with the top of the nasal mask cushion, gradually working  
down the sides until the nasal mask cushion is seated in the  
nasal mask channel.

5. After the nasal mask cushion is securely reassembled, rinse the  
entire mask thoroughly and allow to air dry out of direct sunlight.  
NOTE: Make sure the mask is dry before use. Inspect the mask after  
cleaning.
