3. Connecting the C-Series Heated Humidifier
WARNING
•Make sure the flow generator is switched off and unplugged at the power outlet before connecting or disconnecting the humidifier.
•Always remove the water chamber before connecting or disconnecting the humidifier and the flow generator.
1.Disconnect the flow generator power cord from the socket at the rear of the flow generator.
2.Fit the connector seal to the air outlet on the flow generator. Ensure the connector seal is fully seated over the air outlet.
Connector seal
3.Place the humidifier base on a firm, level surface near your bed at a level lower than your sleep- ing position. Ensure the surface is not sensitive to heat and moisture, or use a protective mat.
4.Align and place the flow generator on the humidifier base.
5.Connect the (black) humidifier signal cable into the signal cable socket, and the (gray) power transfer cable into the power socket at the rear of the flow generator.
Do not attempt to use the system unless both cables are connected to the flow generator.
6.Plug the humidifier power cord into a power outlet. When the combined C-Series system is powered, the green indicator lights on the flow generator and humidifier turn on.
4. Attaching and Detaching the Water Chamber
7. Starting Therapy
1.Connect one end of the air tubing firmly onto the air outlet of the water chamber and the other end to your mask.
2.Fit your mask as described in your mask user instructions.
3.If necessary, set the humidity level as described in the section “Setting the Humidity Level”.
4.Press 
on the flow generator to start therapy. Therapy starts straight away. The heating indi- cator on the flow generator lights when the humidifier is on.
5.Lie down and arrange the air tubing so that it is free to move if you turn in your sleep.
WARNING
Do not leave a long length of air tubing around the top of your bed. It could twist around your head or neck while you are sleeping.
8. Stopping Therapy
To stop your therapy at any time, remove your mask and press 
on the flow generator.
9. Cleaning and Maintenance
WARNING
•Beware of electrocution. Do not immerse the flow generator, humidifier or power cord in water. Always unplug the device before cleaning and be sure that it is dry before plug- ging it back in.
CAUTION
•Do not use any of the following to clean any part of the humidifier. These solutions may cause damage and reduce the life of the product:
–bleach, chlorine, alcohol- or ammonia-based solutions
–moisturizing, antibacterial or glycerine-based soaps
–water softening and unapproved descaling agents.
•Do not wash the water chamber in a dishwasher.
Daily
Wash the water chamber and connector seal in warm water, using a mild detergent (see previous caution). Rinse them thoroughly with clean water and allow them to dry away from direct sunlight.
12. General Warnings and Cautions
A warning alerts you to possible injury.
•The humidifier, including the associated tubing, is for single-patient use and must not be re-used on another person. This is to avoid the risk of cross-infection.
•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 user-serviceable parts inside. Repairs and internal servicing should only be performed by an authorized service agent.
•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 C-Series Heated Humidifier.
•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 C-Series Heated Humidifier is designed only for use with the ResMed C-Series System. Do not use the humidifier with any other CPAP device.
•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.

14. Servicing
This product (C-Series Heated Humidifier) should be inspected by an authorized ResMed Service Center 5 years from the date of manufacture. Prior to this, the device is intended to provide safe and reliable operation provided that it is operated and maintained in accordance with the instructions provided by ResMed. Applicable ResMed warranty details are provided with the device at the time of original supply. Of course, as with all electrical devices, if any irregularity becomes apparent, you should exercise caution and have the device inspected by an authorized ResMed Service Center.
15. Technical Specifications
The C-Series Heated Humidifier is indicated for humidification of the air delivered from the ResMed C-Series CPAP System.
CAUTION
Federal law restricts this device to sale by or on the order of a physician.
2. Contraindication
The C-Series Heated Humidifier is contraindicated for use with patients whose upper (supraglottic) airway has been bypassed. Please also refer to your C-Series Flow Generator User Guide for con- traindications associated with CPAP therapy.
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.
