Switching off the spray aspirator with the 4-way foot switch
Vacuum system, Reference to safety instru ctions
Tip: The factory-set suction power can be adjusted in the water unit by a
service engineer.
Spray aspirator
You can angle the suction handpiece by turning it.
The end of spray aspirator cannula A has air intake openings to ensure
that the suction flow is not fully interrupted if it attaches itself to the oral
mucosa. This prevents backflow from the hose into the oral cavity if the
cannula attaches itself.
The thick suction hose can be used for surgical suction. To insert a
surgical cannula, please attach the adapter supplied.
It can be adjusted so that the suction flow of the spray aspirator can be
interrupted or reactivated by pressing the 4-way foot switch at the base of
the chair in any direction; see"Linking the spray aspirator to the 4-way foot
switch" [ → 161].
Saliva ejector
A curved cannula that can be lodged in the corners of the mouth is
provided for saliva ejection.
CAUTION
The cannula attaches itself to the oral mucosa.
The patient's oral mucosa is irritated by the vacuum.
➢ Make sure to hold the suction cannula in such a way that the
cannula opening cannot attach itself to the oral mucous membranes
by accident. Sirona recommends using spray aspirator cannulas
with air intake opening or ventilation holes see "Spare parts,
Consumables [ → 221].
CAUTION
The spray aspirator can be switched off with the 4-way foot switch.
Due to the lack of suction flow, fluid may run back out of the spray
aspirator and into the patient's mouth.
➢ Always remove the spray aspirator from the patient's mouth before
switching it off.
NOTICE
Suction removal of metal oxides from blasting devices
Observe the safety information on the "Vacuum system" [ → 17].
