Installing the Air Filters
CAUTION: A properly installed, undamaged gray foam lter is required for proper operation.
The device uses a gray foam lter that is washable and reusable, and a white ultra-ne lter that is disposable. The
reusable lter screens out normal household dust and pollens, while the ultra-ne lter provides more complete
ltration of very ne particles. The gray reusable lter must be in place at all times when the device is operating. The
ultra-ne lter is recommended for people who are sensitive to tobacco smoke or other small particles.
The reusable gray foam lter is supplied with the device. A disposable ultra-ne lter may also be included. If your
lter is not already installed when you receive your device, you must at least install the reusable gray foam lter
before using the device. To install the lter(s):
1. If you are using the white disposable ultra-ne lter, insert it into the lter area rst, mesh-side facing in, towards the device.
2. Insert the required gray foam lter into the lter area after the ultra-ne lter.
Note: If you are not using the white disposable lter, simply insert the gray foam lter into the lter area.
Connecting the Breathing Circuit
To use the system, you will need the following accessories in order to assemble the recommended circuit:
• Philips Respironics interface (nasal mask or full face mask) with integrated exhalation port, or Philips Respironics
interface with a separate exhalation device (such as the Whisper Swivel II)
WARNING: If you are using a full face mask (a mask covering both your mouth and your nose), the mask must be
equipped with a safety (entrainment) valve.
• Philips Respironics 22 mm (or 15 mm) exible tubing, 1.83 m (6 ft.)
• Philips Respironics headgear (for the mask)
WARNING: If the device is used by multiple persons (such as rental devices), a low-resistance, main ow bacteria lter
should be installed in-line between the device and the circuit tubing to prevent contamination.
To connect your breathing circuit to the device, complete the following steps:
1. Connect the exible tubing to the air outlet on the side of the device.
Note: Make sure the Tubing type setting (15 or 22) matches the tubing you are using (Philips Respironics 15 or 22
mm tubing).
Note: Heated Tubing should only be connected to the Air Outlet Port of the compatible System One Heated
Humidier and not to the Air Outlet Port of the therapy device.
Note: If required, connect a bacteria lter to the device air outlet, and then connect the exible tubing to the
outlet of the bacteria lter.
Note: When using the bacteria lter, the device performance may be affected. However, the device will remain
functional and deliver therapy.
2. Connect the tubing to the mask. Refer to the instructions that came with your mask.
3. Attach the headgear to the mask if necessary. Refer to the instructions that came with your headgear.
