Preface The ZOLL AED 3TM defibrillator is an Automated External Defibrillator (AED) that can be used for both adult and child victims of sudden cardiac arrest. The defibrillator incorporates a sequence of audio and visual prompts to help rescuers follow established AHA/ERC/ILCOR Guidelines for use of AEDs. The ZOLL AED 3 Service Manual is to be used primarily by the ZOLL® Technical Service Department in conjunction with the ZOLL AED 3 Operator’s Manual and the ZOLL AED 3 Administrator’s Guide. The ZOLL AED 3 defibrillator does not require preventative maintenance due to its automatic self tests. However, this manual provides optional maintenance tests you can perform periodically according to local protocols. This manual contains the following sections: Preface-Contains safety warnings and an overview of the manual’s contents. Review this section thoroughly before attempting to use or service the ZOLL AED 3. Chapter 1-Maintenance provides the recommended procedures for evaluating the condition and performance of the ZOLL AED 3 defibrillator. Chapter 2-Troubleshooting describes possible problems and solutions and lists the error log messages that indicate the AED requires technical service. Chapter 3-Functional Description provides technical descriptions of the ZOLL AED 3 defibrillator modules. Appendix-Hardware/System Architecture contains a diagram of the ZOLL AED 3 hardware/system.

Checklist-Located on the back page of this manual and used to record the results of the maintenance tests in Chapter 1.
Conventions Throughout this document, text prompts and voice prompts are indicated by capital italicized letters, such as CALL FOR HELP. WARNING! Warning statements describe conditions or actions that can result in personal injury or death. CAUTION Caution statements describe conditions or actions that can result in damage to the defibrillator.
NOTE Notes contain important additional information on servicing the defibrillator.
Safety Considerations Only qualified personnel should service a ZOLL AED 3 defibrillator. Before using this defibrillator, read the ZOLL AED 3 Operator’s Manual. Before servicing any equipment, review these safety considerations and read this manual carefully. WARNING! The ZOLL AED 3 defibrillator can generate as much as 2250 volts with sufficient current to cause lethal shocks.
Before discharging the defibrillator, warn everyone near the equipment to STAND CLEAR. Do not recharge, disassemble, or dispose of the battery in fire. The battery might explode if mishandled.

Chapter 1 Maintenance The ZOLL AED 3 defibrillator automatically performs functional testing during periodic self tests. However, this chapter provides optional maintenance tests you can perform periodically according to local protocols. The following tests and maintenance instructions are included in this chapter:
• Self Tests • Cleaning • Manual Maintenance Tests
Self Tests The ZOLL AED 3 defibrillator performs the following self tests to verify AED integrity and its readiness for emergency use:
• Battery Installation • Power On • Manual • Automatic (Daily or Weekly, based on configuration) • Automatic Monthly AED Passed Following successful completion of all self tests, the status indicator displays a Self Test green check () to show that all tests passed and that the AED is ready to use. AED Failed Self Test
9650-000751-01 Rev. E
ZOLL AED 3 Service Manual

If the status indicator is blank following the completion of any self test, the ZOLL AED 3 defibrillator is not ready for use and may be defective. Remove the AED from service and consult the section “Chapter 2 Troubleshooting” on page 17 to help determine the problem.
Self Test Functions The following functions are verified during self tests. Table 1 on page 5 lists the functions that are included in each self test.
• Battery Capacity: Verifies that the battery usage indicator shows adequate battery capacity remaining.
• Defibrillation Pads Connection: Verifies that the defibrillation pads are properly preconnected to the device.
• Defibrillation Pads (CPR Uni-padzTM)/Battery Expiration Verification: Verifies that the defibrillation pads are within their expiration date and the battery is within its install-by date. Note: CPR Uni-padz are the only electrodes that have an expiration date that is recognized by the ZOLL AED 3 device.
• ECG Circuitry: Tests that the ECG signal acquisition and processing electronics are functional.
• Defibrillator Charge and Discharge Circuitry: Verifies that the device’s defibrillator electronics are functional and can charge and discharge at 2 joules. The following tests also include a separate 200 joule charge/ discharge test: Battery Installation Self Test, Automatic Monthly Test.
• Microprocessor Hardware/Software: Verifies proper function of the AED microprocessor electronics and the integrity of its software.
• CPR Circuitry and Sensor: Determines that CPR monitoring and compression depth detection are functional (if defibrillation pads with CPR functionality are connected).
• Audio Circuitry: Verifies that voice prompts are working.
Automatic Self-Test Transfer All ZOLL AED 3 defibrillators come standard with Program Management OnboardTM intelligent monitoring technology to transfer self-test data. If configured, the AED can automatically transfer self-test information over Wi-Fi to the ZOLL PlusTracTM AED program management system or to another AED program management provider.

Cleaning the AED After each use, clean and disinfect the defibrillator with a soft, damp cloth using either 90% isopropyl alcohol, or soap and water. You can also use a chlorine bleach and water mixture (30 ml/liter water) to clean the defibrillator (except on the contacts and connectors). NOTE Wipe down the defibrillator with water after using any cleaning solution. Chlorine residue that remains on the LCD screen may cause damage. DO NOT: • Immerse any part of the defibrillator in water. • Use chlorine mixture on contacts or connectors; this will degrade the contacts over time. • Use ketones (MEK, acetone, etc.) to clean the defibrillator. • Use abrasives (e.g., paper towel) on the display window or graphic screen. • Sterilize the defibrillator.
