Programme
blocks
The wash block sequence is pre-determined and is the same as the
sequence in the programme chart (see “Programme chart”).
–
Pre-wash 1
to
3
A pre-wash removes coarse soiling and foaming agents.
–
Main wash 1
and
2
Depending on the load, cleaning generally takes place at temperat-
ures between 45 °C and 65 °C with the addition of appropriate
cleaning agent.
–
Interim rinse 1
to
4
In the interim rinse stages, the process chemicals from the
previous wash blocks are rinsed off and neutralised where neces-
sary by adding appropriate neutralising agents.
–
Final rinse 1
and
2
To avoid deposits and corrosion on the load, demineralised (DI) wa-
ter should preferably be used if available for the final rinse.
Thermal disinfection is carried out in accordance with the A
0
concept of EN ISO 15883 at temperatures between 80 and 95 °C
with relevant holding times.
–
Drying
Adequate drying reduces the risk of corrosion caused by residual
moisture on the load.
Programme block parameters are accessible only to the W&H Cus-
tomer Service Department, with the exception of the dispensing of
rinsing agent and drying parameters.
