Problem
Why it happened
What to do
I’m having difficulty
adjusting the heated
humidifier setting
or the heated tube
temperature setting.
The blower is not turned
on, or the humidifier or
heated tube is not fully
connected.
The humidifier setting and tube temperature
settings can only be adjusted from the Therapy ON
display screen. 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.
The water in the water
chamber runs out before
morning.
Water chamber was not
full at start of session.
Mask leak is excessively
high. The ambient
conditions are very dry/
cool.
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.
I hear a leak or whistling
sound coming from
my therapy device or
humidifier (not related
to mask leak).
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.
Check therapy device air inlet is not obstructed,
and filters are free of debris 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.
