DC Operation of the 9001
The DeVilbiss CPAP Model 9001 can be operated from a 12V DC power source in a
motor home, recreational vehicle or boat. Connect the DeVilbiss CPAP to a 12V ciga-
rette lighter in a vehicle with a negative ground using DeVilbiss adapter plug part #
7304D-619. There are no switches or fuses to change for DC operation. Do not use the
CPAP in a moving vehicle.
CAUTION– If this device is used with a 12VDC power source, loss of power will result
in loss of CPAP therapy; there is no internal battery. If the 12VDC power
supply is an automobile or truck battery, the battery should be profession-
ally tested to make sure the battery is properly charged. A weak battery can
result in insufficient voltage to operate the CPAP and loss of CPAP therapy.
Do not operate the unit while the vehicle is running.
CAUTION– Use only DeVilbiss DC power cord part #7304D-619. Use of any other cord
may cause damage to the CPAP or the vehicle electrical system.
CAUTION– The CPAP will operate for 8 hours on a car battery. The battery should be
professionally tested before using the CPAP overnight to make sure that the
battery is in good condition and is fully charged.

OPERATION OF THE 9001
CO2 Rebreathing
CO2 rebreathing is minimized during use by providing 3cmH2O minimum pressure,
which creates airflow through mask vent holes. It is important that mask vent holes
are not blocked.
During a single fault, the blower is maintained within spec or at less than the maximum
limited pressure. For a firmware detected fault, the blower is set to a fail safe mode in
which the blower is turned off and the detected error code is shown on the LCD display.
CO2 rebreathing is minimized by keeping the mask vent holes open at all times.
1. Plug CPAP into AC power using appropriate power cord. Will work on 100 to 240
volts AC (50 to 60 Hz) with no changes except for the end of the power cord
where it plugs in the wall. Model 9001 will also operate on 12 VDC.
2. The display will show
Set Pres and the CPAP will increase to the prescribed CPAP
pressure.
3. The display shows the CPAP pressure prescribed by the doctor.
4. Press the Delay button to start the pressure delay cycle, if prescribed. Pressure
will decrease to the Delay Pressure setting and return to the prescribed Set pres-
sure after the Delay Time has expired
Figure 8.
5. When you awake in the morning, press the ON/OFF button to turn the blower
OFF
Figure 9.
Model 9001 also has automatic start up and automatic shut off features. To start the
blower, connect the 6 foot hose and mask, then breathe into the mask. The blower will
start after the 2nd or 3rd breath. To turn the blower OFF, remove the mask. After
about one minute of mask off, the blower will turn OFF.
