7.3. W.H.E. SYSTEM (WATER HYGIENIZATION EQUIPMENT)
The W.H.E. system ensures a safe, physical, separation of the dental
unit water system from the water mains thanks to a water free fall section
(in compliance with EN 1717).
In addition, system continuously delivers hydrogen peroxide inside water
circuit with a final concentration inside ducts of 0.06% (600 ppm), which
is suitable to carry out bacteriostasis.
To this end, the use of PEROXY Ag+ (CEFLA s.c.) is recommended; or
3% Hydrogen Peroxide (oxygenated water, 10 volumes).
Description of the system.
The W.H.E. system is positioned inside the connection box and is always
active.
A tank (a) located inside the water unit contains the disinfectant fluid to
supply the system.
The W.H.E. system is automatically disabled when the S.H.S.
system is enabled.
Disinfectant fluid running out warning.
When the oxygenated water present in the tank (a) is running out, the
dental unit emits an intermittent sound (3 BEEPS) that is repeated at
every start-up of the equipment.
Console with LCD TOUCH display:
a special icon (G) appearing on the display indicates that the disinfectant
fluid is about to run out.
Console with DIGIT display:
a warning message (W060) appearing on the display indicates that the
disinfectant fluid has run out.
If disinfectant fluid has run out, the dental unit will
nevertheless continue working, but it will use UNTREATED
mains water.
We recommend topping up disinfectant fluid as soon as
possible.
The exhaustion of the disinfectant inside the tank also causes a
clear slowdown in the operations of use of the W.H.E. system,
which should not be considered a fault. The normal operation of
the system is obtained by restoring the correct level of
disinfectant inside the relevant tank.
Disinfectant fluid tank filling
To fill up, use pure PEROXY Ag+ or 3% oxygenated water (10 volumes) only, without diluting them.
Wear eye protection and gloves when carrying out this operation.
Dental units of A3 PLUS model:
• Open tank cover flap (a)
• Pour the disinfectant fluid into the tank until it is full.
Tank capacity: approx. 500 cc.
• Close tank flap.
