LCD: NO MASK VENT
• Connection of a non-vented mask.
• Mask expiratory flow port (vent)
may be blocked.
• Use of supplemental oxygen with
a vented mask.
• Ensure your mask has an expiratory flow port
(vent).

Daily Cleaning
Mask
Clean the mask according to the instructions supplied with the mask.
Air tubing
Disconnect the air tubing from the device (and humidifier, if used) and
store the tubing and mask in a clean, dry place until next use.
CAUTION
Do not store the air tubing in direct sunlight as the tubing may harden over
time and eventually crack.
Humidifier
If you are using a humidifier, clean it according to the instructions supplied
with the humidifier.
Weekly Cleaning
1
Remove the air tubing from the device and the mask.
2
Wash the air tubing in warm water using mild detergent. Rinse thoroughly, hang and
allow to dry.
3
Reconnect the air tubing to the air outlet and mask.
CAUTION
• Do not use bleach, chlorine-, alcohol- or aromatic-based solutions
(including all scented oils), moisturising or antibacterial soaps to clean the
air tubing or the device. These solutions may cause hardening and reduce
the life of the product.
• Do not hang the air tubing in direct sunlight as the tubing may harden over
time and eventually crack.
Periodic Cleaning
1
Clean the exterior of the device with a damp cloth and mild liquid soap.
2
Inspect the air filter to check if it is blocked by dirt or contains holes. See “Replacing the
Air Filter” on page 14.
WARNING
Beware of electric shock. Do not immerse the flow generator or power cord in
water. Always unplug the flow generator before cleaning and be sure that it
is dry before reconnecting.
