Problem
I'm having difficulty adjusting
the heated humidifier
setting or the heated tube
temperature setting.
The water in the water
chamber runs out before
morning.
I hear a leak or whistling
sound coming from my
therapy device or humidifier
(not related to mask leak).
I accidentally spilled water
into my humidifier basin.
Note: For information on troubleshooting your therapy device, see the manual included with your therapy device.
Why it Happened
The blower is not turned
on, or the humidifier or
heated tube is not fully
connected.
Water chamber was not
full at start of session.
Mask leak is excessively
high. The ambient
conditions are very dry/
cool.
The therapy device air
inlet may be obstructed.
The humidifier or tube is
not fully connected. The
humidifier seals are not
fully seated or are missing.
The water chamber has
been filled beyond the
maximum fill line.
The humidifier setting and tube temperature settings can only
be adjusted from the Therapy ON display screen on the therapy
device. Confirm that the blower is turned on, and that the settings
are visible on the right side of the screen, then adjust to desired
comfort. If the blower is on but the humidifier settings are not
displayed on the Therapy ON screen, then unplug the device.
Confirm that the humidifier and/or heated tube electrical contacts
are not obstructed or damaged. Then reconnect the humidifier and/
or heated tube, and reconnect the device's power supply. Turn the
blower on; if the settings are still not visible, contact your provider
for assistance.
Under most conditions, a full water chamber should last for a typical
sleep session. However, many factors impact water consumption,
including: the ambient temperature and humidity in your bedroom,
your humidifier or heated tube settings, the level of mask leak, and
the duration of your sleep session.
First, make sure that the water chamber is filled to the maximum fill
line at the start of your sleep session. Check that your mask is fitted
properly, and adjust as needed to reduce mask leak to normal levels.
You may use the Check Mask Fit function to evaluate your mask
fit. Also, confirm that the device, humidifier, humidifier seals and
tube are connected properly and not leaking. You may also choose
to lower your humidifier and/or heated tube settings or change the
humidification mode from Fixed to Adaptive humidification mode to
increase the time that your humidifier water will last.
Check therapy device air inlet is not obstructed, and filters are clean
and properly inserted. Confirm that the device, humidifier, and tube
are connected properly and not leaking. Confirm that the humidifier
lid seal and dry box seal are present and properly seated; if needed,
gently press around the perimeter of the seals to reseat them.
A small amount of water spilled in the basin of the humidifier will
not harm your device. A small spill in the humidifier will evaporate
under normal humidifier use. However, too much water in the
humidifier basin could spill over the humidifier lid hinge and might
damage your furniture.
Disconnect power from the device. Remove the water chamber,
pour out any excess water until the water level is at or below the
maximum fill line and set the chamber aside. Separate the humidifier
from the therapy device, and pour out the spilled water. Once
the heater plate has cooled, wipe the inside of the humidifier with
a paper towel or soft cloth. If needed, dry the underside of the
humidifier and confirm that your table top is dry. Reconnect the
humidifier and power supply, and reinstall the water chamber.
