About this manual This Technical Reference Manual contains information required to service and repair the GE Healthcare S/5 ADU Carestation and the AS/3 Anesthesia Delivery Unit S/N: 6 000 000 and greater. Note that prior to May 2005, units were manufactured with serial numbers ranging from 40 000 000 to 40 300 743. Units manufactured in May 2005 and after, start in the serial number range 6 000 000 and greater. Throughout this manual the S/5 Anesthesia Delivery Unit and AS/3 Anesthesia Delivery Unit will be referred to as the ADU. The manual is divided into sections from 1 to 10, which describe maintenance, and into sections from A to E, which describe the ADU modules. NOTE: In this manual the US version of menus and menu items are used. The UK English/ International version of the ADU uses a different terminology than the US version in the System Checkout menu. The two versions differ in the following way: US version

Safety
Monitoring It is the responsibility of the user to ensure that, when in use, the ADU is configured with all the monitoring and protection devices as required by the relevant part of ISO 8835.
WARNING
To prevent hazards arising from incorrect delivery of gases, the ADU shall always be used with the following monitoring: •
O2 monitor according to ISO 7767/EN 12598
• •
Agent monitor according to EN ISO 11196 CO2 monitor according to ISO 9918/EN 864
•
Expired volume monitor according to IEC 60601-2-13/EN 740
General warnings and cautions Throughout this manual, a WARNING indicates a hazardous situation which - if not corrected - may result in patient injury or death. A CAUTION indicates a situation in which the ADU or devices connected to it, may be damaged.
Hazards related to improper installation, use and service of the ADU WARNING
The following precautions must be observed: • • • • • • • •
The ADU is only to be operated by, or on the order of a physician. The installation of the ADU is only to be done by trained service personnel. Service is only to be done by trained service personnel with proper tools and test equipment. Read the User’s Reference Manual and the Technical Reference Manual before performing service to the ADU.

Confirm that the ADU and AC-powered equipment used together with the ADU is properly grounded. In order to reduce the risk arising from excessive leakage currents, and in accordance with EN 740, an anesthetic workstation shall not be provided with more than four operator accessible auxiliary mains socket outlets. The connection of equipment to auxiliary mains socket outlets may increase the patient leakage currents to values exceeding the allowable limits in the event of a defective protective earth conductor. Do not autoclave any part of the ADU system except those specified in User’s Reference Manual through the use of steam or ethylene oxide. When cleaning the exterior - make sure that no liquid enters the interior of the ADU. Do not touch any exposed wiring or conductive surface while the cover is off and the ADU energized. The voltages present may cause injury or death. The power cord and plug must be intact and undamaged. Do not remove the grounding pin from the power plug. Do not use extension cords or adapters of any type. Replace the power cord if its cracked, frayed, broken or otherwise damaged. Only use hospital grade, grounded electrical outlets and power cord. Adequate grounding can only be ensured if the equipment is connected to a receptacle marked "Hospital Grade". Make sure that any external equipment which is to be connected to GE Healthcare equipment is hospital grade grounded. To avoid the risk of electric shock, this equipment must only be connected to a supply mains with protective earth.
NOTE: The battery in the ADU is only intended to provide backup power in case of a mains failure. Do not disconnect ADU from mains power during operation. NOTE: The A-ELEC-02 provides battery backup to the monitor. The notes in ADU User’s Reference Manual chapters ‘ADU Safety Features’ and ‘Monitoring’ do not apply. NOTE: The Auxiliary outlet in the A-ELEC-00, which is being referred to in the ADU User’s Reference Manual, is missing from the A-ELEC-02. NOTE: The A-ELEC-02 electronics unit is recognized from the sticker on the left in the back panel. NOTE: When the A-ELEC-02 is connected to provide battery backup for the monitor and the monitor switch is OFF, the ON/Standby of the monitor is controlled from the ADU switch.
Hazard related to explosion, fire or burns WARNING

•
•
Flammable anesthetic gases such as ether and cyclopropane must not be used with the ADU. Only agents which comply with the requirements for non-flammable anesthetic agents according to IEC 60601-1, shall be used. There is always a risk wherever anesthethic agents are used and handled. Do not use the ADU in insufficiently ventilated areas, thus avoiding raised concentrations of anesthetic agents in operating rooms. Use gas scavenging at all times. As this workstation is not to be used with flammable anesthetic agents, the use of antistatic breathing tubes and face mask is not recommended. Burns may occur if antistatic or electrically-conductive breathing tubes are used while high-frequency electric surgery equipment is in use. High pressure or medical gases may cause explosion or burn strongly when reacting with organic material such as lubricants, paint, greasy fingerprints, dirt, dust fluff, and other organic waste. No oil, grease, or silicone-based lubricants must be used. Only PTFE-based, oxygen compatible lubricants are allowed.
Other hazards WARNING
A reconfiguration of user defaults must be done by a trained physician or by trained personnel on order of a physician.
WARNING
Out of order PC boards shall not be repaired by the user but by GE Healthcare.
WARNING
Never immerse vaporizers in any liquid.
CAUTION
Open the reserve gas cylinder valves (yokes) slowly to avoid harmful pressure shock.
CAUTION
Use mild detergent solution to clean the unit. Do not use ammonia-, phenol-, or acetone-based cleaners as these cleaners may damage the surface of the ADU.
CAUTION
Electrostatic discharge through PC boards may damage the components on them. Wear a static control wrist wrap before touching the PC boards.
CAUTION
Handle all PC boards by their non-conductive edges and use anti-static containers when transporting them.
CAUTION
Do not gas sterilize the ADU.
CAUTION
Remove the battery fuses when the ADU is stored for a long time. This prevents the batteries from being discharged.
CAUTION
Do not transport the ADU standing only on its wheels, use original or equal transport package to avoid shock damages.
CAUTION
The ADU must be stabilized at temperature specified in “Technical specifications” section before use.
