1) Preface
This service manual is intended for use by ACUTRONIC Medical Systems AG trained and authorized
service personnel.
ACUTRONIC Medical Systems AG does not condone or approve of service activity on its products by
other than ACUTRONIC Medical Systems AG trained or authorized personnel and ACUTRONIC
Medical Systems AG is not responsible for any unauthorized repairs or modifications, or any repairs or
modifications made by unauthorized procedures.
Use of the incorrect part, or failure to exercise due care in the installation, removal, servicing, checkout
or calibration of parts and equipment or the use of unauthorized accessories, may result in damage to
the equipment which may in turn result in damage in property and injury (including death) to persons.
The purchaser and installer of these parts shall bear full responsibility and liability for the above.
All maintenance performed within the applicable warranty period must be authorized in advance by a
ACUTRONIC Medical Systems AG service representative in order to retain the warranty status of the

2) CMOS Handling Precautions
The following precautions must be observed whenever a circuit board or an integrated circuit is handled.
Failure to do so may result in serious damage to the fabian.
Place fabian and parts on a grounded, conductive work surface
Ground yourself (with a strap having about 1 MOhm resistance )
Ground the frame of any test instrument or soldering iron to be used
If any circuit boards are to be stored or transported, enclose them in conductive (anti-static) envelopes

perform in accordance with applicable specifications. If within one year after the original shipment it is found
not to meet this standard, it will be repaired, at Acutronic Medical Systems AG option, or replaced at no
charge when returned to an Acutronic Medical Systems AG service facility. Any modification to the
equipment or rework or repair by other than Acutronic Medical Systems AG approved personnel will render
this warranty null and void. Acutronic Medical Systems AG shall not be liable for any indirect, special or
consequential damages, even if notice has been given of the possibility of such damages.

10) Software update
A Software “update” can also be an “upgrade “ with new features.
The fabian HFO Ventilator uses a basic pneumatic structure that is controlled by two PIC
micro controllers on the main board.
A single board computer (CPU) on the main board provides the user interface and
supervises the pneumatic controllers.
The ventilator can be used in different operating (ventilation) modes that are completely
software controlled.
The control of the fabian HFO essentially consists of following component

12.1.1 Exchange of fuses
General note:
Fuses shall be replaced by fuses of the same type and value indicated on fabian only.
ACUTRONIC Medical Systems AG recommends the exchange of fuses by authorised
service personnel only.
The main fuses are located in the fuses compartment of the power entry module at the rear
panel of fabian.
Procedure:
1. Disconnect power cord from machine to avoid electrical shock!
2. With a forceps, open the fuses compartment. Pull out the drawer, which contains the
fuses.
3. Exchange the fuses with fuses of the same type and value.
4. Install the compartment back.
5. Make sure, that the arrow directs to the right side.
6. The correct values for the fuses are indicated on the label above the power entry
module.

Test instruction fabian
13.1 Calibration - tools
Special test procedures and instruments are required to perform the testing.
Only use test instrument which is regularly checked and calibrated by certified calibration service, to
guarantee that they have the required accuracy.
The following equipment is required:
- Respirator tester e.g. PF300 flow analyser (IMT)
- fabian test lung ( part no. 1116 )
- Test lung small ( part no.: 7204 )
- Miniature pressure regulator. Range approx. 60 mbar e.g. Aircom Art No.: R900-3,5WK
- Electrical safety tester
WARNING
Hazardous voltages exist within the ventilator. Always observe appropriate safety
precautions when working on the ventilator while the machine is connected to an
electrical power source to prevent possible accidental injurious electrical shock.
WARNING
After calibration and/or replacement of any assembly(ies), always repeat the
complete test procedure according the fabian checklist.
