Connecting the Breathing Circuit
To use the system, you will need the following accessories in order to assemble the recommended circuit:
• Respironics interface (nasal mask or full face mask) with integrated exhalation port, or Respironics interface with a
separate exhalation device (such as the Whisper Swivel II)
• Respironics 6 ft. flexible tubing
• Respironics headgear (for the mask)
WARNING: If the device is used by multiple persons (e.g., rental devices), a low-resistance, main flow bacteria
filter 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 flexible tubing to the air outlet on the top of the device.
Note: If required, connect a bacteria filter to the device air outlet, and then connect the flexible tubing to the
outlet of the bacteria filter.
Note: Do not use the heated humidifier feature when using a bacteria filter. No water should be in the humidifier
chamber when using the bacteria filter.
Note: The bacteria filter is recommended to protect the patient, care provider and equipment from the
transference of a virus or bacteria through the breathing circuit.
2. Connect the tubing to the mask. Refer to the instructions that came with the mask.
WARNING: The exhalation device (e.g., Whisper Swivel II) or exhalation port (on masks with an integrated
exhalation port) is designed to exhaust CO
exhalation device.
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. You must ensure that the entrainment valve is functioning properly.
3. Attach the headgear to the mask if necessary. Refer to the instructions that came with your headgear.
Where to Place the Device
Place the device on a firm, flat surface somewhere within easy reach of where you will use it at a level lower than
your sleeping position. Make sure the filter area on the back of the device is not blocked by bedding, curtains, or
other items. Air must flow freely around the device for the system to work properly. Make sure the device is away
from any heating or cooling equipment (forced air vents, radiators, air conditioners).
CAUTION: Do not place the device directly onto carpet, fabric, or other flammable materials.
CAUTION: Do not place the device in or on any container that can collect or hold water.
CAUTION: Make sure that the drain holes on the bottom of the device are not blocked.
CAUTION: Take precautions to protect furniture from water damage.
WARNING: Do not use this device without the water chamber installed.
Supplying AC Power to the Device
CAUTION: If this device has been exposed to either very hot or very cold temperatures, allow it to adjust to
room temperature (operating temperature) before beginning the following setup procedures. Do not operate the
device outside of the operating temperature range shown in the Specifications.
WARNING: Route the wires to avoid tripping.
WARNING: This device is activated when the power cord is connected. Pressing the START/STOP button
turns the airflow and humidifier (if activated) on or off.
Complete the following steps to operate the device using AC power.
1. Plug the pronged end of the AC power cord into an electrical outlet that is not controlled by a wall switch.
2. Plug the power cord's connector into the power inlet on the back of the device.
3. Ensure that all connections are secure.
IMPORTANT: To remove AC power, disconnect the power cord from the electrical outlet.
WARNING: Inspect the power cord often for any signs of damage. Discontinue use and replace if damaged.
WARNING: Do not use extension cords with this device.
