5.1

Vacuum Operation

The VC-10 power switch is a 3-position switch. The unit is shipped with the switch in the OFF
position, which is the central position for this switch (see Figure 4a).
For vacuum operation to occur, the power switch must be placed in the ON position. The power switch
is set in the ON position by fully depressing the left edge of the switch (see Figure 4b).
To turn the VC-10 device OFF at any time during the procedure or at the end of the procedure, return
the power switch to the OFF position (central position for the 3-position switch).
For foot pedal operation, confirm that the foot pedal is properly attached. Note: Close the front door
prior to using the VC-10 device. Fully depress the right edge of the power switch and then depress the
foot pedal (refer to Section 3.4 Nomenclature and Symbology, and Figure 4c). Note: Releasing the foot
pedal will discontinue the suction.
For intermittent suction, fully depress the foot pedal when suction is desired. If depressing the foot
pedal does not result in suctioning, it may become necessary to vent the system by utilizing the "slide
vent" of the sterile collection tubing set to allow the foot pedal actuation to continue.
Alternatively, if the Vacurette tip becomes clogged, clear clogged Vacurette tips as necessary and
continue suctioning. If suctioning does not continue, see Section 7.0, #1a.
The maximum attainable vacuum with the vacuum-adjust valve in the fully clockwise position, at sea
level, is approximately 71 cm Hg. There is a reduction of vacuum by 2.6 cm Hg per 1,000 feet (8.5
mm Hg per 100 meters) of elevation above sea level.
The vacuum-adjust knob is pre-set at the factory in the fully counterclockwise position for minimum
vacuum. To increase vacuum, turn the vacuum-adjust knob clockwise (see Figure 5). To determine the
maximum vacuum level available at any particular setting, turn the unit on and observe the vacuum
reading on the gauge while completely occluding the intake opening of the collection bottle.
Vacuum Gauge Color Range
(at outer dial "tick" marks)
0 to 7.4 cmHg: White
7.5 to 50 cmHg: Red
50 to 60 cmHg: Yellow
60 to 75 cmHg: Green
Vacuum-tight connections are assured when the collection system tapered fittings are properly
connected and maintained. Proper sealing will maintain a consistent vacuum level throughout the
system.
To minimize moisture build-up that can lead to corrosion in the vacuum pump, utilize the appropriate
Disposa-Filter (see Figure 2) and monitor canister collections and related overflow protection/safety
trap collection systems. Running the unit for approximately 5 minutes after each procedure (with the
system open to atmosphere) will also minimize moisture build-up.

Vacuum Checks

1. Turn the VC-10 unit on, either by setting the power switch to the ON position (Figure 4b) or to the
foot actuator position for foot pedal operation (Figure 4c).
2. Place a finger over the inlet at the end of the collection tubing handle. Observe the vacuum gauge
until it stabilizes. The level shown on the gauge is the maximum vacuum level at the particular
setting of the vacuum adjust knob.
3. Turn the vacuum adjust knob counterclockwise to decrease vacuum or clockwise to increase
vacuum.
4. Verify that the vacuum gauge has stabilized after each knob adjustment before using the system
in a procedure.
5. Slide the slip-ring on the rotating handle of the collection tubing assembly over the opening
to maximize the suction to the tip of the Vacurette cannula. Slide the slip-ring away from the
opening to reduce the suction at the tip of the Vacurette cannula.
