General
• Service documentation for the Servo…™ Ventilator
System consists of:
– User's manual
– Service Manual
– Spare Parts List.
• Documentation for all optional equipment
included in the Servo…System is also available.
• The User's manual is an indispensable comple-
ment to the Service Manual for proper servicing.
• Serial number of the unit is found on a label
attached to the Patient Unit close to the supply
gas inlets.
• System version number can be found in the
Status window on the User Interface. Make sure
that the version of the User's manual corresponds
to this system version.
Text inside a box is used to highlight important
information.
• In addition to the Important information given
here and in the related documents (e. g. in the
User's manual), always pay attention to applicable
local and national regulations.
• Responsibility for the safe functioning of the
equipment reverts to the owner or user in all
cases in which service or repair has been done by
a non-professional or by persons who are not
employed by or authorized by Siemens, and when
the equipment is used for other than its intended
purpose.
• Data on internal pressures in the Servo…System
are given in Pa (bar).
Airway pressures are given in cm H2O (Pa).
1 hPa = 1 mbar 1 mbar = 1 hPa

instructions in the User's manual, chapter
Routine cleaning and chapter Regular
maintenance, section Extended cleaning of insp.
channel.
• With power supply connected to the Servo…
System, there are energized electrical
components inside the unit. All personnel must
exercise extreme caution if fault tracing or
adjustments are performed with power supply
connected and with user interface and patient
unit covers removed.
Symbols used in this manual
•ESD sensitive components. Make
sure to take precautions to avoid
damaging ESD sensitive components.
•Special waste. Make sure to discard
worn-out batteries and other
disposable parts according to local
regulations and in an environmentally
acceptable way.
•Recycling. Recycle if possible.
Recycling facilities may not be
available in all areas.

package for sensitive electronic devices. Siemens
will not otherwise assume responsibility for the
materials used, the work performed or any
possible consequences of same.
• The device complies to standards and require-
ments as stated in the Servo…Ventilator System –
User's manual.
Installation
• Only personnel trained and authorized
by Siemens shall be permitted to install
the Servo…System. The installation and
handing over procedures are described
in the ”Servo…Ventilator System –
Installation Instructions”.
Functional check
• After any installation, maintenance or service
intervention in the Servo…System, perform a
Pre-use check according to instructions in the
Servo…Ventilator System – User's manual.
Service
• The Servo…System must be serviced at
regular intervals by personnel trained
and authorized by Siemens.
Any maintenance or service must be
noted in a log book provided.
• It is recommended that maintenance
and service is done as a part of a service
contract with Siemens.
• Preventive maintenance must be performed at
least once every year as long as the unit is not
used more than normal. Normal operation is
estimated to correspond to approx. 5.000 hours
of operation. Details are found in this Service
Manual, chapter ”Preventive maintenance”.
• Worn-out batteries must be recycled or
disposed of properly according to local
