Warnings General • The aspirator is intended for use by qualified personnel only. You should read this guide

before using the aspirator. • Before using the aspirator with a patient, you must test the device in its normal

configuration to ensure proper operation. • Do not modify this equipment without authorization of the manufacturer. • This operator’s guide is not meant to supersede any controlling operating procedure

regarding the safe use of the aspirator. • Follow all governing regulations regarding the disposal of any part of this medical device,

the handling of materials contaminated by body fluids, and shipment of the Li-ion batteries.

Aspirator • The aspirator can operate from its internal battery or from an external power source. When

using an external power source, position the power supply cables to avoid accidental disconnect. • The use of accessories and cables other than those sold by ZOLL may result in increased emissions or decreased immunity of this device. • Portable and mobile RF communication equipment may affect the performance of this device.

General Information • Do not connect to an electrical outlet controlled by a wall switch or dimmer. • Position the mains plug so it is easy to disconnect the device from mains. • Grounding: • Do not remove the grounding conductor from the power plug. • Do not use extension cords or adapters of any type. The power cord and plug must

be intact and undamaged. • As with all medical equipment, carefully route the aspirator accessories, patient cabling, and

external power cables to reduce the possibility of patient entanglement or strangulation. • Failure to make proper connections could cause harm to the patient or operator. • Do not use the aspirator during magnetic resonance imaging (MRI) scanning. • Do not operate the aspirator with a patient when the USB port is connected to any other

device (the USB port is used only for servicing the aspirator).

Batteries and Power Supply • If you witness a battery or the battery compartment starting to balloon, swell up, smoke, or

feel excessively hot, turn off the device, disconnect external power, observe it in a safe place for approximately 15 minutes, do not attempt to remove the battery from the device, and send the device for service. Never puncture or disassemble the battery packs or cells. • Only use the power supply provided with the device. Use of any other power supply could cause damage or create a fire and/or destroy the battery and device.

Operator Safety • The collection canister and patient suction tubing and/or catheters should be considered

potentially hazardous. Use proper Personal Protection Equipment and handle accordingly. • Electric shock hazard: Do not remove equipment covers. You may only perform

maintenance procedures specifically described in this guide. Refer all servicing to ZOLL or a ZOLL-authorized service center. • Possible explosion hazard if used in the presence of flammable anesthetics or other flammable substances in combination with air, oxygen-enriched environments, or nitrous oxide. • This device is not intended for use in explosive atmospheres. • Pins of connectors identified with the ESD warning symbol should not be touched. Always use precautionary procedures with ESD-sensitive connections.

Patient Safety • Do not place the device or external power supply in any position that might cause it to fall

on the patient. • Do not lift collection canister by its lid. The weight of the contents might cause the lid to

separate from the canister. • Never attempt to carry the aspirator by the hoses, cords, canister holder, or the collection

canister. This can result in damage to the device and possible injury to the user or patient. • Never service the aspirator while in use with a patient.

Cautions • Do not omit the canister from the suction path for any patient procedure. • Use only the AC/DC power supply that ZOLL provides with the device. • During any cleaning or decontamination procedure, ensure that there is no external power to

the aspirator and that the device is turned off. • Only qualified biomedical equipment technicians should service the device. • Internal components are susceptible to damage from static discharge. Do not remove device

covers.
