Porter recommends that effective scavenging can be achieved with the ball float in the green bar area of
the acrylic sight glass, however NIOSH publications conclude that higher vacuum flows of up to 45 L/min
are most effective. To meet the NIOSH recommendation of 45 L/min adjust the ball above the green bar
area.
C A U T I O N : D O NOT PROCESS ANY LIQUIDS OR DEBRIS THROUGH THE AVS.
This contamination can cause damage and affect the function of the unit. The AVS is designed to regulate
the vacuum flow level for scavenging of Nitrous Oxide / Oxygen gas only.
C A U T I O N :
The vacuum system should be equipped with a back flow shutoff device to prevent
carryover of fluids into equipment attached to the piping systems. It is recommended that a separate
vacuum trap be used between the piping system and the vacuum station inlet or any equipment that is
attached to the system.
In-line Vacuum Control Kit (Option)
The kit includes a vacuum control block with sight glass, vacuum tube holder, adapter “T” and straight
fitting. The vacuum control block can be inserted directly into the High Volume Evacuation (HVE) line or
may be placed “in-line” by cutting the vacuum hose and attaching the cut ends of the tubing to both ends
of the vacuum control block. Adjust the vacuum flow using the control knob. Vacuum flow is most
effective when the ball float is set within the green bar area. Refer to FM-809 for User Instructions,
Assembly, Installation and Cleaning.
Bag Tee
The Bag Tee assembly features a Non-rebreathing Valve and an Emergency Air Intake located on the
Bag Tee, which comply with American Dental Association guidelines. The non-rebreathing valve has a
back flow check valve, which prevents exhaled gases from entering the breathing bag (no carbon dioxide
buildup). The emergency air intake has a valve that allows room air to be inhaled into the breathing
circuit by the patient. A breathing bag is attached to the metal portion of the Bag Tee and is a reservoir
bag for the delivered analgesia gases, which when taken together with the two valves above, becomes
the visual barometer for monitoring the patient’s respiration rate. The bag moves in and out with each
inhalation and exhalation.
Bag Tee Installation to Flowmeter: Screw knurled seal down tight onto flowmeter making sure the rubber
washer is inside the seal nut. When tight, the bag tee should not rotate.
Note: Fit mask to patient so inner mask is pulled down tight secure to the face. Outer mask should not
be against the face. Vacuum needs to be drawn into outer mask during inhalation.
