INTRODUCTION

Thank you for buying the Omron A.I.R.S. Model NE-U03V MicroAir® Nebulizer.
The MicroAir changes liquid medicine into an aerosol form. This change is
done using vibration.

The Micro-Air was designed with your needs in mind and weighs less than one
pound. The Micro-Air runs with a standard AC adapter or with 4 "AA" batteries
(batteries not included).

The Micro-Air silently delivers medication continuously or intermittently. The
Micro-Air medication cup holds 5-ml. The LED feature indicates "power ON"
and "battery status". The Micro-Air can be used with mask or mouthpiece for
your convenience and comfort. The Micro-Air is completely adaptable to any
requirement with its full range of accessories.

Using your Micro-Air for any reason other than its intended purpose will
void the warranty.

ON/OFF button again to turn off the unit.

NOTES:
A. The green operation light will be on during

continuous operation.

B. A blinking green light during battery power

means that the batteries are low and need to
be replaced as soon as possible.

4. Nebulization Rate The unit has been pre-set to nebulize at an aver­age rate of 0.25 ml per minute. Nebulization
rates may vary due to different medications.
Check with your healthcare provider or
pharmacist regarding your medication.

NOTE: The mesh cap may be damaged by hardened medication that is left in
the vibration horn effecting how the unit nebulizes. The following are maintenance
recommendations after each use to keep your unit working at its best level.

UNIT DISASSEMBLY & MAINTENANCE

NOTE: Be sure that the unit is turned OFF.
Remove the medication cup and dispose of any
remaining medications.

Be sure to nebulize all medication from the unit.
The medication cup needs to be removed while
the unit is on to remove all medication that
might be in the mesh cap or transducer. The unit
will no longer provide any aerosol when these
parts are completely empty.

NOTE: The lack of any misting will occur
with a high pitched sound when all medication
has been nebulized. Quickly turn the unit off
when this sound is heard it shows that there is
no more medication in the unit.

Pour a mixture of one part vinegar and three
parts distilled water into the medication cup
after each use. Nebulize the mixture for about
45 to 60 seconds. Remove the medication cup
and run the unit until it can no longer mist.
Turn the unit off at this point.

NOTE: Make sure that there is no medication
left on the mesh cap or horn that can dry and
cause damage or breakage to the mesh cap
when removed from the unit.

Place 2-3 drops of the water/vinegar mixture
onto the mesh cap surface when dried medica­tion is noted. Nebulize distilled water from the
medication cup for at least 30 seconds.

We recommend that a small bottle of the
water/vinegar mixture be kept with your unit
at all times for proper cleaning.

COMMON QUESTIONS ABOUT THE MICROAIR

Q. Can I use any type of double “AA” batteries in the

MicroAir?

A. We recommend that alkaline batteries be used for best performance.

Q. How long will a set of batteries operate the MicroAir?

A. The expected battery life is 300 minutes of operation.

Q. What other sources of power can the MicroAir use?

A. The MicroAir can operate from either AC power or battery.

Q. How often should I clean the MicroAir?

A. You must clean the MicroAir after each use. Guidelines for handling an

cleaning the mesh cap are detailed on page 11.

Q. How do I clean the MicroAir?

A. See pages 10-11 for cleaning instructions.

Q. If the mesh cap has very small holes, is it likely to clog

during use?

A. The mesh cap will operate without clogging with proper cleaning after

each use as described in this manual.

Q. What should I do if my mesh clogs during operation?

A. Turn the unit OFF. Follow the instructions to remove the mesh cap.

Repeat the cleaning instructions. Replace the cap and restart the unit.

Q. How do I clean the internal part of the horn?

A. Mix 1 part vinegar and 3 parts distilled water. Operate the MicroAir with

2 ml of this solution to maintain working order.

Q. Should I keep all parts of the MicroAir on the unit

at all times?

A. Yes. The unit needs to be taken apart for cleaning and reassembled for

storage. It is recommended to keep the unit and any accessories in a car­rying case for convenience and protection. You are less likely to break or
lose a part if the unit remains assembled.

COMMON QUESTIONS ABOUT THE MICROAIR

Q. Will the mesh break easily?

A. The mesh is like all small delicate parts that can be broken if not gently

handled. It is important that after cleaning the mesh that it be placed back
on the unit. This will protect the mesh from damage while the unit is not
being used. Be sure to replace the unit cover after use for added protection.

Q. How much medication is left at the end of treatment in

the medication cup?

A. There should only be a few drops of medication at remaining in the cup

after a treatment. Medication that remains in the cup is a result of the
method by which the unit operates that can not deliver all medication.

Q. After using the MicroAir there is some medication inside

the mouthpiece. Is this normal?

A. Yes. Up to .02 ml can remain in the mouthpiece from condensation that

results from the aerosol process.

Q. Should I take my treatment with the MicroAir set on

continuous flow or should I use the intermittent method?

A. Consult with your healthcare provider as to the type of delivery method

of your medication.

Q. When do I change the mesh?

A. The mesh is projected to last up to 6 months with recommended cleaning

and maintenance. However, if the mesh should break during use, you
must replace it.

Q. Under normal use, what changes will I see in the mesh

when it needs to be replaced?

A. The unit will start to "flood" the mesh during treatment and the aerosol

product will stop. IF cleaning procedures on page 11 do not correct the
flooding, the mesh cap should be replaced.

Reminder: Daily mesh cap cleaning is essential to keep your
Micro-Air working properly. See page 11 for mesh cap
cleaning instructions.
