7.
The vacuum Waste Tank contains a ball float shutoff to
prevent accidental overflow. The Tank should be emptied
when it is ¾ full.
The High Volume (HVE) vacuum system contains a screen
inside the Waste Tank container. The screen is used for
collecting large debris upon vacuum intake. Clean screen
when necessary.
To empty the Waste Container:
A. Unplug the power cord.
B. Disconnect the hoses.
C. Empty container.
D. Reconnect hoses.
E. Plug in power cord.
NOTE:
The waste container has a ball float shutoff to prevent
accidental overflow. If the waste container becomes full
and the ball float activates, the vacuum motor may not
restart, and could potentially blow the fuse. Immediately
empty waste container to continue operation.
7. CAVITRON WATER OUTLET:
Provides water via standard 1/4” quick disconnect to
independent Cavitron or scaler units requiring a water supply.
OPERATION:
After the unit has been set up and you have made yourself
familiar with the system functions, there are two operating modes
to select from:
•
On/Off Switch Operation
- Switch ‘ON’ activates the
vacuum and 3-way air/water syringe.
• Foot Pedal Operation
- Depressing the Foot Pedal
activates the handpiece.
1. Connect the power cord to the Express Air Unit and plug into
appropriate power source.
IMPORTANT
: Ensure that the Voltage Selector Insert is
properly configured for the power source - Refer to Page 4.
2.
FOOT PEDAL OPERATION:
A.
Turn the On/Off Switch on the front of the Fan Housing
to the ‘ON’ (I) position. The vacuum and syringe will
become operational.
B. Depress the Foot Pedal: The handpiece will activate.
The Syringe, HVE, and Saliva Ejector will remain
operational.
CAUTION:
Some new ADU-17A compressor motors might require
a 2-week “break-in” when first used. As a precaution
against stalling the compressor or possibly blowing the
fuses during this break-in period, it is recommended
that the foot pedal be removed from the System for
approximately 5 minutes before each initial daily startup,
during the first 2 weeks of use.
WARNING:
Always operate a high-speed handpiece with water
coolant. Operating a high-speed handpiece without
water coolant can cause thermal injury to the patient
and damage the handpiece. Consult the handpiece
manufacturer’s instructions for additional information.
