12. General Warnings and Cautions
A warning alerts you to possible injury.
•The humidifier, including the associated tubing, is for
•Always place the humidifier device lower than the level of the patient. If it is placed at or above the level of the patient, heated water may flow down the air tubing and into the mask.
•There exists the possibility that if the device is placed above the level of the patient and is tipped over, or if the tubing is filled with condensate, the mask might fill with water. The device should be placed below the level of the patient so that in the event of the device being tipped over, the tubing and mask do not fill with water.
•The humidifier should only be used with delivery tubes or accessories recommended by ResMed. Connection of other delivery tubes or accessories could result in injury, or damage to the device.
•If liquids are inadvertently spilled into or on the humidifier, unplug the device from the power outlet. Disconnect the humidifier from the flow generator and allow it to drain and dry before using.
•Do not operate the humidifier if the device has a damaged power cord.
•Do not operate the humidifier if it is not working properly or if any part of it has been dropped or damaged.
•Keep the power cord away from heated surfaces.
•No perceptible heating effect may be felt at low heat settings, depending on the ambient temperature.
•Do not attempt to dismantle the humidifier. There are no
•Do not drop or insert any object into any opening or tubes.
A caution explains special measures for safe and effective use of the device.
•Only use distilled water with the
•Use the humidifier only for its intended use as described in this guide.
•Make sure that the water chamber is empty before transporting the humidifier.
•The water chamber should not be attached when transporting the humidifier in the carry bag. Place the water chamber in a separate compartment in the carry bag.
•The
•If you put the device on the floor, make sure the area is free from dust and clear of bedding, clothes or other objects that could block the air inlet.
•Be careful not to place the device where it can be bumped and knocked over.
•Blocking the air inlet or tubing while the device is operating could cause it to overheat.

1.Unplug the power cord from the power outlet and allow ten minutes for the heater plate and any excess water to cool.
2.Detach the air tubing from the water chamber.
3.Press down the release latch on the humidifier and carefully slide the water chamber from the humidifier base.
4.Discard any excess water.
5.Filling the Water Chamber
WARNING
•Do not overfill the water chamber, as water may enter the flow generator and air tubing.
•Remove the water chamber from the humidifier before filling it with water.
CAUTION
Do not use any additives (eg, scented oils and perfumes). They may reduce the humidifica- tion output of the humidifier and/or cause deterioration of the water chamber materials.
Carefully fill the water chamber to the maximum water level mark with distilled water only.
Fill with distilled water only. Using distilled water will prolong the life of your water chamber. Water from the faucet typically contains minerals that will damage the base of your water chamber.
6. Setting the Humidity Level
The aim of humidification is to deliver moist air to your mask, but to avoid having condensation form in the air tubing. The temperature and humidity of the surrounding air will affect the setting you need.
You can adjust the humidity setting at any time before or during therapy, to find the most comfort- able and effective setting.
To set the humidity level press 
or 
on the flow generator; notice that the screen displays “H” and the selected humidity level (eg, H. 3).
The OFF setting switches heated humidification off and delivers minimum humidification. A setting of 6 delivers maximum humidification.
The humidification setting remains displayed on the screen for five seconds.
