Recommended Cleaning and Flushing Procedure for
Oral Evacuation Systems with Wet Separators
1. All dental chair suction tips must be flushed with water
after each use and at the end of each day. If disinfectants
are used, they must be compatible with other fluids
collected, and the separator/system piping materials of
construction. Water dilution is optimal for maintaining
the integrity of wet separators, as it reduces the concen-
tration of potentially harmful agents.
2. Separators are provided with automatic wash down
solenoid valves. Once the vacuum system is shut down
and the control panel wash down selector switch is in the
“automatic” position, it will energize the wash down at a
minimum of 3 minutes per separator. This procedure
should be performed at the end of each day whenever
the vacuum system has been utilized.
3. The separator is provided with a funnel and valve for
manually pouring disinfectants into the separator when
the vacuum producer is shut down. If used, the separator
must be immediately flushed out using the automatic or
manual wash down valves. For manual wash, open the
manual upper and lower water wash down valves (with
spring return) to flush the separator with water. After
approximately 3 minutes, close the upper valve. If using
the manual discharge, keep the lower valve open to

continue whirlpool action; open the 4" quick-opening
discharge valve to drain out the separator. Proceed with
flushing action until the discharge water becomes clean.
(If using the pump system to drain liquids, the pump
should pump the separator contents to an amalgam
separator or holding tank.) Then close the lower water
wash down valve and let the separator drain out. Close
the quick-opening discharge valve to the separator.
4. Refrain from using bleach or other chlorine containing
disinfectants in the vacuum line system and separator.
These have been shown to impede mercury collection in
the amalgam separator and can cause rapid corrosion
and failure of the vacuum wet separator/piping system.
5. All chemicals introduced to the system must be
reviewed for chemical interaction and compatibility with
system materials of construction. The customer is
responsible for this review as The Spencer Turbine
Company is not responsible for material compatibility.
6. The above recommendations are minimum operating
requirements and may need to be revised based on the
actual field operating conditions.
Customer is responsible for insuring that all materials
collected are disposed of in accordance with all local,
state and federal disposal regulations.
