Engler ADS 2000 - Turning On the ADS 2000; Startup and Self-Test Procedure

TURNING ON THE ADS 2000
1. Verify that the oxygen supply hose is connected properly. Open the O2 valve to begin
oxygen supply to the ADS 2000. The oxygen supply must be regulated to 50 PSI. Make sure
that the vaporizer (if in circuit) is "OFF" .
2. Place the "POWER" and "MASK" switches in the "O" position. Place the "SET /
RUN" switch into the "SET" position. Check that the Toggle Switch located at the rear
of the unit is set to “Normal” 50 PSI.
3. Place your thumb over the open end of the gas-sampling elbow that is connected to the end
of the breathing circuit.
Note: By placing your thumb over the gas-sampling elbow you are creating a closed circuit for
the ADS 2000 built in self-test feature.
Note: The gas sampling system hose must be properly connected before the ADS 2000 self-
test is initiated.
4. While still holding your thumb over the sampling elbow, place the Power switch to "I" or "On" .
The ADS 2000 will now perform a self-test. This will be indicated by the LCD display as shown in
Figure 1. Continue to hold your thumb over the end of the sampling elbow until this test is
complete.
