A7 Plus – OPERATOR'S MANUAL
7.6. A.C.V.S. SYSTEM (AUTOMATIC CLEANING VACUUM SYSTEM)
Description of the system.
This system allows cleaning the surgical suction system. System
features a tank ( c ) with detergent fluid and two couplings ( d ) used for
suction tube flushing. Detergent fluid tank has a total capacity of 500 cc.
The flushing cycle is automatic and should usually be carried out at the
end of each surgery so as to complete the operating unit cleaning and
disinfection procedure.
It is recommended to use STER 3 PLUS (CEFLA s.c.)
diluted in a 6% solution (equivalent to 60 ml of product in 1
litre of water).
How to start the flushing cycle.
To start the flushing cycle, proceed as specified below:
• Make sure that tank ( c ) contains enough detergent fluid (at least half
tank must be full).
• Remove suction tube terminals from assistant's board supports,
making sure that suction motor starts.
• Open suction tube terminal mechanical locks.
• Insert suction tube terminals inside the relevant couplings (d) located
under manifold. The vacuum created inside the Venturi tubes starts the
flushing cycle.
• Flushing cycle operating steps:
- mains water supply for 50 sec. with intermittent operation (2 sec.
ON - 1 sec. OFF),
- stop of water flow and supply of 10cc. of disinfectant fluid,
- stop of disinfection fluid supply and suction continuation for 10
sec.
• The interruption of the suction flow, with consequent motor stop,
determines flushing cycle end.
The message "Put suction tubes back in place" will appear on the
display.
• Now simply put suction tube terminals back into their supports on
assistant's board to go back to working condition.
Tank filling.
When detergent fluid inside tank ( c ) drops below the min. level, proceed as follows:
• Move the dental chair fully up.
• Position the dental chair at maximum height.
• Pour the detergent liquid into the tank until it is full.
• Refit the tank by turning it clockwise.
Stopping the flushing cycle.
If system detects a malfunction, an error message will be displayed (see paragraph 10).
once stop causes are removed, the flushing cycle will restart automatically.
