11. HVE AND SALIVA EJECTOR VACUUMS
The unit is equipped with a high volume
evacuator (HVE) and low volume saliva
ejector system (Fig. 37). Both high and low
volume systems can operate
simultaneously. When the vacuum holder
toggle switches are toggled Off (to left
side), the vacuum system will stay off,
even when the vacuum valves are
removed from their holders. When the
vacuum holder toggle switches are toggled
On (toward the red dot), the vacuum will
start automatically when the vacuum
valves are removed from their holders.
12. WASTE CONTAINER
-- When the HVE or
saliva ejector instruments are in use, the
vacuum pump will run and waste from the
vacuum system will collect in the 1.8 liter
plastic waste container located on the
back side of the unit (Fig. 38). The
container provides two separate waste
compartments: one for HVE and the other
for the saliva ejector. (The HVE compart-
ment contains a vacuum-intake screen for
collecting large debris.) Each compartment
includes its own 85%-full sensor. When
either one of these sensors reaches the
85%-full level, an audible alarm will start to
16.

13. AUXILIARY WATER OUTPUT
(Fig. 21)--
Water or other solutions placed in the
water bottle can be withdrawn through the
auxiliary water output using an Aseptico
fitting (PN AA-60) attached to tubing. The
output has an auto shutoff to prevent
leakage.
