8.1 Introduction

8.1.1 How to use this chapter

This chapter describes how to repair the major ventilator subassemblies and their
components. These repair procedures include removal, installation, and
adjustment, as applicable. This section does not provide complete breakdowns of
all assemblies and complete disassembly information. Repair procedures are
provided mostly for major components. For a complete illustrated parts
breakdown (IPB), refer to Chapter 9. Do not rely exclusively on Chapter 9 for
removal and installation of parts.

8.1.2 General repair safety

• When servicing the ventilator, be sure to familiarize yourself with and adhere
to all posted and stated safety warning and caution labels on the ventilator
and its components, and on any service equipment and materials used. Failure
to adhere to such warnings and cautions at all times may result in injury or
property damage.
• To prevent patient injury, do not use a ventilator if it requires repair.
• To prevent personal injury or death, do not attempt any ventilator service
while a patient or other person is connected to the ventilator.
• Use personal protective equipment whenever exposure to toxic fumes, vapor,
dust particles, blood pathogens, and other transmittable diseases and
hazardous material can be expected. If in doubt, consult an environmental,
health, and safety specialist or an industrial hygienist before servicing the
ventilator.
• To prevent electrical shock hazard and possible personal injury, always
disconnect electrical power sources before servicing the ventilator. This means
disconnecting not only mains power but also battery power from the BBU
PCB. If the ventilator must be serviced with the power on, be careful to avoid
electrical shock. Avoid reaching into the ventilator. Follow accepted safety
practices for electrical equipment when testing or making equipment
adjustments or repairs.
• To prevent possible personal injury, always disconnect oxygen source from the
ventilator before service.
