10.1.4 Disinfection procedures with the A
0
control system
The standard factory setting is A
0
= 60.
It is cleaned at a tank temperature of up to 74° C. The tank heating is active during the
cleaning. After every second as of 65° C in the cleaning tank, the measured tank
temperature is allocated one factor (the higher the temperature, the higher the factor).
These factors are continually added until the desired hygiene value, e.g. A
0
60, has been
reached. The dripping phase and, following that, the final rinse begin when the cleaning
time with hot water of approx. 83° C that has already been set in the programme is
reached or exceeded.
The A
0
value is shown on the display.
The tank temperature falls when the programme begins, depending on the items being
cleaned. The set programme cycle time can be exceed by the time it takes to reach the
prescribed disinfection parameters.
10.1.5 Water change programme
A water change programme can be assigned to the programme pre-selection buttons. In
the standard setting, this is only assigned to button III.
After completing the cleaning programme, all of the water is pumped out of the tank. A
fresh water final rinse follows and this water is pumped out as well. After that, the
programme has ended and the light in the programme start button goes out.
The following options now exist:
1. Press the “0” button (Off button), and the appliance stays off.
2. Open the door, remove the basket, close the door; the machine is then ready for
operation (tank filling, heating)
3. Switch to program 1 or 2; the machine is then ready for operation (tank filling, heating)
4. Press the Start button, and the machine is then ready for operation (tank filling,
heating); the cleaning and disinfection program starts directly after that.
10.1.6 Detergent dosing / Disinfectant dosing
The dosing equipment is designed to automatically add liquid alkaline detergent or
disinfectant to the wash water.
The liquid is transported from the storage tank to the wash tank with a pump via a hose
conduit in the cleaning tank. The dosing equipment is self-priming. Dosing occurs during
each filling cycle and at the beginning of each program cycle via timer control.
We recommend the dosage of approx. 2 ml/l alkaline detergent for disinfection using the
A
0
control system and approx. 10 ml/l disinfectant for chemo-thermic disinfection.
Observe the chemical manufacturers' dosing instructions.
