E. VACUUM TEST
Steps What to do

IMPORTANT WARNINGS

1 Clamp the aspiration Before connecting the suction ring on the aspiration tubing, check
tubing at its end (close that internal air lumen of the ring are not obstructed by surgical
to the ring connector) residues.
This obstruction, resulting from insufficient or inappropriate
cleaning, would create pseudo-aspiration and risk the loss of
vacuum.
2 Press the test button This test procedure will check the efficiency of the pumps and the
(A8) pressure (if gas turbine is selected).
The unit will check each The test should be made :
pump: P1, then P2. • prior to surgery,
Vacuum test ends with a • whenever tubing is changed,
short audible "beep". • whenever a red indicator light is illuminated
The unit can only be operated if the test is passed.
The display (A7) indicates:
• "PE"
• then atmospheric pressure (mmHg)
• then "P1"
• then the pressure obtained by pump P1 (mmHg)
• then "P2"
• then the pressure obtained by pump P2 (mmHg)
• then atmospheric pressure (mmHg)
When atmospheric pressure "PE" is indicated on the display, one
can hear a single "beep".
Stopping suction is indicated by a "beep" sound".
3 The test is passed if The vacuum level provided by the console depends on the local
LED (A3) is ON atmospheric pressure, and thus on the elevation. The system
displays the actual vacuum value (in mmHg).
The higher the elevation, the less efficient the suction. The
atmospheric pressure decreases with elevation (approx: 8
mmHg/100 m).
The suction capacity is proportional to the difference in pressure
between the lowest level of vacuum pump and the local
atmospheric pressure.
The higher the vacuum power, the smaller the value displayed.
When the ring is fixated on the eye the vacuum value must be less
than 250mmHg. If the value displayed is above, the unit must be
immediately turned off and sent back to Moria for a servicing.
At sea level (Elevation = 0 m)
Atmospheric pressure = 760 mmHg

IMPORTANT WARNINGS
When "Low Vacuum" function is activated, LED A5 is ON.
The "Low Vacuum" allows for a low level of vacuum of the suction
ring on the eye.
For safety reasons, when the low vacuum function is activated, the
electrical motor can only be activated for a backward pass.
