Removing condensation from the air tube
If there is moisture or liquid remaining in the air tube, be sure to follow the 
procedure below to remove any moisture from within the air tube.
1) Make sure that the air tube is connected to the air connector on the 
compressor.
2) Remove the air tube from the nebulizer kit.
3) Turn on the compressor and pump air through the air tube to expel the 
moisture.
Changing the air filter
If the air filter has been used for more than 60 days, replace it with a new 
one.
1. Pull the air filter cover off the compressor.
2. Change the air filter.
Remove the old air filter with a sharp object 
and insert the new air filter.
3. Put the air filter cover back in place.
Make sure it is attached properly.
Notes:
•  Use only OMRON air filters designed for this device. Do not operate without a filter.
•  Do not wash or clean the filter. If the air filter becomes wet, replace it. Damp air filters 
can cause blockages.
•  There is no front or back orientation for the air filters.
•  Check that air filters are clean and free of dust before inserting them.
Cleaning and daily disinfecting
Cleaning
Clean the parts after each use to remove residual medication. This will avoid 
inefficient nebulization or infection.
■
 Washable parts
• Nebulizer Kit, Mask (PVC)/(SEBS), Mouthpiece, Nosepiece, 
Air Tube (Silicone)
Wash them in warm water and mild detergent (neutral detergent). Rinse them 
thoroughly with clean hot tap water and allow to air dry in a clean place.
■
 Non-washable parts
• Compressor, Air Tube (PVC)
Firstly, make sure that the power plug is unplugged from the power outlet. 
Wipe clean with a soft cloth moistened with water or mild detergent 
(neutral detergent).
• Air Filter
Do not wash or clean the air filter. If the air filter becomes wet, replace it. 
Damp air filters can cause blockages.
Disinfecting
Always disinfect the parts after the last treatment of the day. If the parts are 
heavily stained, replace them with new ones.
To select a method for disinfection, refer to the table below.

an example of commercially available disinfectant.
A.  Use a commercially available disinfectant. Follow the instructions 
provided by the disinfectant manufacturer.
Note: Never clean with benzene, thinner or a flammable chemical.
B.  Parts may be boiled between 15 to 20 minutes.
After boiling, carefully remove the parts, shake 
off excess water and allow to air dry in a clean 
environment.
 Caution: Handling the Vaporiser Head
•  Always wash the vaporiser head after each use.
•  Do not use a brush or pin to clean the vaporiser head.
•  When disinfecting the parts by boiling, be sure to boil them in plenty of water.
•  Do not boil vaporiser head together with objects other than applicable nebulizer 
accessories.
How to use
 Warning:
•  Clean and disinfect the nebulizer kit, mask, mouthpiece or nosepiece before using 
them when as follows:
- the first time after purchase
- if the device has not been used for a long period of time
- if more than one person uses the same device
For the instructions, refer to “Cleaning and disinfecting” section.
1. Make sure that the power switch is in the off ( 
 ) position.
2. Plug the power plug into a power outlet.
3. Remove the cap and the inhalation top from 
the medication tank.
4. Add the correct amount of prescribed 
medication to the medication tank.
5. Make sure that the vaporiser head is securely 
attached to the inhalation top.
6. Put the inhalation top back inside the 
medication tank.
7. Attach the cap and mask, mouthpiece 
or nosepiece to the nebulizer kit tightly.
Note: 
It is not necessary to attach the cap when 
nebulizing with Adult mask. If the amount of 
aerosol is too great, attach the cap.
8. Attach the air tube. 
Twist the air tube plug slightly and push it firmly into 
the air tube connector.
9. Hold the nebulizer kit as 
indicated on the right.
Follow the instructions of your 
doctor or respiratory therapist.
 Caution:
Do not tilt the nebulizer kit at an 
angle of greater than 45 degrees 
in all directions. Medication may 
flow into the mouth or it may result 
in not nebulizing effectively.
10. Press the power switch to the on ( 
 ) position. As the compressor 
starts, nebulization begins and aerosol is generated.
Inhale the medication.
11. When treatment is complete, turn the power off and unplug the 
compressor from the power outlet.
Troubleshooting
Check the following if the device should fail during operation.
Problem Cause Remedy
Nothing happens when the 
power switch is pressed.
Is the power plug plugged into 
a power outlet?
Check that the plug is inserted 
in a power outlet. Unplug then 
reinsert the plug if necessary.
No nebulization or low 
nebulization rate, when the 
power is on.
Is there medication in the 
medication tank?
Add the correct amount of 
medication to the medication tank.
Is there too much/little 
medication in the medication 
tank?
Is the vaporiser head missing 
or not assembled correctly?
Attach the vaporiser head 
correctly.
Is the nebulizer kit assembled 
correctly?
Assemble the nebulizer kit 
correctly.
Is the nozzle blocked? Make sure that the nozzle is free 
of blockages.
Is the nebulizer kit tilted at a 
sharp angle?
Make sure that the nebulizer kit is 
not tilted at an angle of more than 
45 degrees.
Is the air tube connected 
correctly?
Make sure that the air tube 
is correctly connected to the 
compressor and nebulizer kit.
Is the air tube folded or 
damaged?
Make sure that the air tube does 
not contain kinks.
Is the air tube blocked? Make sure that the air tube is free 
of blockages.
Is the air filter dirty? Replace the air filter with a new
