7.3. M.W.B. system
The M.W.B. system assures secure physical separation of the dental unit
hydrogroup from the municipal water line thanks to a section with free-fall
water.
In addition, the system continuously injects hydrogen peroxide into the water
circuit with a fi nal concentration of 0.06% (600 ppm) in the ducts, suitable
for bacteriostasis.
To this end, it is recommended to use PEROXY Ag+ (CEFLA S.C.); never-
theless, 3% oxygenated water may also be used%.
Description of the system.
The M.W.B. system is located in the utility service center and is always
active.
A specifi c icon [ a ] appears on the doctor's console to signal the M.W.B.
system is turned on.
A tank [ C ], located in the hydrogroup, holds approximately 970 cc of
hydrogen peroxide to feed the system.
The M.W.B. system automatically turns off when the S.S.S. system (if
present) turns on.
Signaling the hydrogen peroxide level is low.
When the disinfectant liquid in the tank ( a ) is about to run out
230 cc.) the icon [ C ] displayed changes into [ D ] and 1 BEEP is emitted.
NOTE: the icon ( D ) is black if the M.W.B. system is turned on while
it is red if the M.W.B. system is turned off.
WARNING!
Should the disinfectant liquid run out , the operating unit will remain
operational but will use mains and NOT treated water.
Filling the tank containing disinfectant liquid.
When the disinfectant liquid in the tank runs out, operate as follows:
• Remove the tank [ a ].
• Remove the cap [ k ] and pour disinfectant liquid into the tank until it is
full.
NOTE: the shape of the cap allows it to be used as a funnel to more
easily fi ll the tank.
• Put the cap and tank back into place.
• Close the cover on the side of the hydrogroup.
ATTENTION!
Fill the tank only with pure PEROXY Ag+ or 3% oxygenated water (10
volumes) without diluting.
Emptying the M.W.B. system tank
This function permits the M.W.B. system's water circuit to be drained, if the
dental unit is going to be left off for several days.
The procedure for emptying the tank is given in paragraph 5.1.1.3.3.
Fault messages shown on the console display.
If the system detects a malfunction, a fault message appears on the display
screen (see paragraph 10.).
If the fault found is minor, the dental unit continues to operate. On the other
hand, if a serious fault is detected, the dental unit shuts down and it is ne-
cessary to call technical support.
PEROXY Ag+ storage.
For proper storage of PEROXY Ag+ follow the manufacturer's instructions
printed on the package.
It is important to keep the package tightly closed and store it in a cool place at a temperature not exceeding 25°C.
WARNING!
Never leave PEROXY Ag+ or oxygenated water in the tank ( a ) for longer than one month.
If you are going to be absent from the surgery for long periods of time (holidays), completely empty out the tank ( a ) before leaving.
NOTE: use a suction tube to empty the tank.
