6. HVE and SALIVA EJECTOR VACUUMS:
The Express II is equipped with a 5-liter Waste
Tank, a High Volume (HVE) hose, and a Low
Volume (Saliva Ejector) hose. Both High and
Low Volume systems operate simultaneously
from the same vacuum source. To gain vacuum
on the HVE, open the HVE valve to full open and
close the Saliva Ejector Valve. To gain vacuum
on the Saliva Ejector, close the HVE and open
the Saliva Ejector to full open.
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.
7. CAVITRON WATER OUTLET:
Provides water via standard 1/4” quick
disconnect to independent Cavitron or scaler
units requiring a water supply.
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.
