WARNINGS

Read the entire manual before using the device.
Use the device only as directed by your physician or healthcare provider.
Use the device only for the intended use as described in this manual. Advice contained in this manual should not supersede instructions given by the prescribing physician.
If you notice any unexplained changes in the performance of the device, if it is making unusual or harsh sounds, if the device or the power supply are dropped or mishandled, if water is spilled into the enclosure, or if the enclosure is broken, discontinue use and contact your ResMed Service Center.
Beware of electrocution. Do not immerse the device, humidifier, power supply or power cord in water. In the event of a spill, disconnect the device from the power supply and let the parts dry. Always unplug the device before cleaning and make sure that all parts are dry before plugging in he device.
Explosion hazard—do not use in the vicinity of flammable anesthetics.
Make sure the power cord and plug are in good condition and the equipment is not damaged.
Keep the power cord away from hot surfaces.
The device should only be used with masks (and connectors1) recommended by ResMed, or by a physician or respiratory therapist. A mask should not be used unless the device is turned on. Once the mask is fitted, ensure that the device is blowing air. The vent hole or holes associated with the mask should never be blocked. Explanation: The device is intended to be used with special masks (or connectors) which have vent holes to allow continuous flow of air out of the mask. When the device is turned on and functioning properly, new air from the device flushes the exhaled air out through the mask vent
holes. However, when the device is not operating, insufficient fresh air will be provided through the mask, and the exhaled air may be rebreathed. Rebreathing of exhaled air for longer than several minutes can, in some circumstances, lead to suffocation. This applies to most models of CPAP or bilevel devices.
Oxygen supports combustion. Oxygen must not be used while smoking or in the presence of an open flame.
Always ensure that the device is turned on and airflow generated before the oxygen supply is turned on. Always turn the oxygen supply off before the device is turned off, so that unused oxygen does not accumulate within the device enclosure and create a risk of fire.
Ports may be incorporated into the mask or in connectors that are near the mask.
Do not leave long lengths of air tubing around the top of your bed. It could twist around your head or neck while you are sleeping.
Do not use electrically conductive or antistatic air tubings.
Do not use the air tubing if there are any visible signs of damage.
Only ResMed air tubing and accessories should be used with the device. A different type of air tubing or accessory may alter the pressure you actually receive, reducing the effectiveness of the treatment.
Only use the ResMed 90W or 30W power supply unit. Use the 90W power supply unit to power the system comprising the device, H5i, air tubing, DC/DC converter and battery pack. The 30W power supply unit is designed to power the device only and recommended for travelling.
Only ResMed products are designed to be connected to the module connector port. Connecting other devices could damage the device.
Blocking the air tubing and/or air inlet of the device while in operation could lead to overheating of the device.

CAUTIONS

Do not open the device enclosure. There are no user serviceable parts inside. Repairs and
servicing should only be performed by an authorised ResMed service agent.
Do not use bleach, chlorine, alcohol, or aromatic-based solutions, moisturizing or antibacterial soaps or scented oils to clean the device, humidifier or air tubing. These solutions may cause damage and reduce the life of these products.
Incorrect system setup may result in incorrect mask pressure reading. Ensure the system is
correctly set up.
Be careful not to place the device where it can be bumped or where someone is likely to trip over the power cord.
Make sure that the area around the device is dry and clean and clear of bedding, clothes or other objects that could block the air inlet or cover the power supply unit.
Ensure that the device is protected against water if used outdoors. Enclose the device in the S9 travel bag for transport.
