4. Slide the humidifier water tank back into the device, using the tracks on the bottom of
the water tank base for proper alignment and connection. Ensure that it is latched into

Connecting the breathing circuit
To use the system, you will need the following accessories in order to assemble the
recommended breathing 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)
• Philips Respironics flexible tubing (12, 15, or 22 mm standard tubing or 12 or 15 mm
heated tubing), 1.83 m (6 ft.)
• Philips Respironics headgear (for the mask)
Warnings
• Do not pull or stretch the tubing. This could result in circuit leaks.
• Inspect the tubing for damage or wear. Discard and replace the tubing as necessary.
• 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.
• If the device is used by multiple persons (such as rental devices), a low-resistance, main
flow bacteria filter should be installed in-line between the device and the circuit tubing
to prevent contamination.
Note: When using the bacteria filter, the device performance may be affected.
However, the device will remain functional and deliver therapy.
