Servo-i Ventilator System Important
1 - 4 Service Manual Revision 02
General
• Service documentation for the Servo-i Ventilator
System consists of:
– User's manual. The User's manual is an
indispensable complement to the Service
Manual for proper servicing.
– Service Manual
– Installation Instructions
– Spare Parts information.
– Documentation for all optional equipment
included in the Servo-i System is also available.
• The Servo-i Ventilator System is referred to as
the Servo-i troughout this manual.
• There are two serial number labels on the unit:
– One label is attached to the Patient Unit close
to the supply gas inlets. The serial number
stated on this label is the ID number of the
Patient Unit. The serial number is also stored in
the SW memory as the 'System ID'.
– One label is attached to the rear side of the
User Interface close to the On/Off switch. The
serial number stated on this label is the ID
number of the User Interface.
• 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 the 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 Maquet, and when
the equipment is used for other than its intended
purpose.

performed or any possible consequences of
same.
• The device complies to standards and
requirements as stated in the 'Servo-i Ventilator
System – User's manual'.
Installation
• Only personnel trained and authorized
by Maquet shall be permitted to install
the Servo-i. The installation and
handing over procedures are described

intervention in the Servo-i, perform a 'Pre-use
check' according to instructions in the 'Servo-i
Ventilator System – User's manual'.
Service
• The Servo-i must be serviced at regular
intervals by personnel trained and
authorized by Maquet.
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 Maquet.
• Preventive maintenance must be performed at
least once every year as long as the unit is not

Main units
The Servo-i is available in different main
configurations:
• Infant
• Adult
• Universal
These main configurations are as standard equipped
with a number of ventilation modes suitable for each
patient category. Further ventilation modes can be
installed via software Option Upgrades.
The Servo-i can be divided into the following main
units:
• User Interface. The User Interface contains all
controls used to set the ventilation and monitoring
parameters. Ventilation parameters as well as other
important information are shown on the User
Interface display.
• Patient Unit. The Patient Unit contains pneumatics
and electronics for gas supply to the patient.
Power supply and battery back-up is also
contained in the Patient Unit.
The Control cable connects the User Interface and
the Patient Unit.
The Servo-i shown in the illustration is mounted onto
the optional Servo-i Mobile cart.
