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 disinfecting

Cleaning

Clean the parts after each use to remove residual medication. This will avoid 

inefficient nebulization or infection.

  Washable parts

• Nebulizer Kit (Inhalation top, Medication tank), Mask (PVC)/(SEBS), 

Mouthpiece, Nosepiece

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

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. (The concentration and residence 

time specified in the table are under the conditions where the service life of the parts 

is tested with each disinfectant used as described in its instruction manual. Please 

note that the testing was not performed for the purpose of ensuring the effectiveness 

of the disinfectants. There is no intention of suggesting that such disinfectants be 

used. Conditions of use and ingredients of disinfectant vary for manufacturers. 

Please read the instruction manuals carefully before use and apply disinfectant to 

each part in an appropriate way. Please notice that service life of the parts may be 

shorter depending on conditions, environments and frequency of use.)

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.

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 inhalation top from the medication 

tank.

4.

  Add the correct amount of prescribed medication 

to the medication tank.

5.

  Put the inhalation top back inside the medication 

tank.

6.

  Attach the mask, mouthpiece or nosepiece to the nebulizer kit tightly.

7.

  Attach the air tube. 

Twist the air tube plug slightly and push it firmly into the air tube connector.

8.

  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.

9.

  Press the power switch to the on ( 

 ) position. As the compressor 

starts, nebulization begins and aerosol is generated. 

Inhale the medication.

10. 

When treatment is complete, turn the power off and unplug the 

compressor from the power outlet.

Troubleshooting

Check the following if your unit 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 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 

one.

The device is abnormally 

loud.

Is the air filter cover attached 

correctly?
