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 approx. 500 cc. of
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.
• For console with LCD Touch DISPLAY:
A specific icon (G) on the dentist's console display signals that
the tank (a) contains a sufficient amount of disinfectant fluid.
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.
