SELF-CONTAINED VACUUM PUMP
The vacuum pump is activated when the Suction/Vacuum On/Off switch, located on the rear of the unit, is in the
ON position, and a suction handpiece is removed from the holder.
Activate Vacuum
Open the suction handpiece valves, flip the vacuum switch to on, and lift the handpiece from the holder to
activate the vacuum pump. The motor will begin to run. If it does not, turn off and verify the waste tank has
been purged. The waste tank has a float switch that will turn off the vacuum pump if the container is filled, and
turn on the waste level indicator light.
To use, open the lever on the evacuation handpiece. To maximize vacuum strength of the evacuation handpiece,
close the lever valve of the other evacuation handpiece whenever it is not in use.
The strength of the vacuum pull to the oral evacuation system is regulated by the vacuum relief
valve. The relief valve on the system is pre-set to approximately 12” Hg, which is ideal for most
general dental as well as surgical procedures.

⚠
CAUTION
SUCTION SEPARATOR AND HOLDING TANK
The self-contained suction system includes a suction canister for separating and holding liquid contents obtained from
evacuation by the suction handpieces. The contents must be emptied daily. The suction canister has an overflow switch to help
prevent accidental overfilling of the canister. However it is important to empty the liquid before it reaches capacity to prevent
potential liquid being pulled into the vacuum pump. Follow the instructions under maintenance for purging and cleaning the
suction system.
A red indication light is mounted on the front of the unit to indicate if the canister is above full. It is important to try to prevent
overfilling the canister as some liquid could be pulled into the vacuum pump.
