DRYING PHASE – Only for WD4060, WD4190 series
The
drying
phase is included in the washing and thermal disinfection cycle, except in programs
“Prewash”, “Auto-Disinfection” and “Service”.
When a program which includes the drying phase is selected, the LED of the function illuminates.
ADJUSTING THE DRYING SETTINGS
The specific buttons for this function allow the effectiveness of the drying process
to be regulated
by increasing or
decreasing the total time of this phase.
3 dashes
light up on the display if the default drying settings are active, while 2
dashes or 1 dash indicate gradually shorter times.
STANDARD STRUCTURE OF THE DRYING PHASE, 3 STEPS
Drying
total time:
t_d = t_1 + t_2 + t_3
Step 1
[t_1]
Step 2
[t_2]
Step 3
[t_3]
Characteristics:
The fan speed is reduced
(1/4 - 1/2 of full speed) to
aid the controlled venting
of steam from the well.
Time and temperature
equal to target values set
by the program. Fan at full
speed.
Cooling phase for load and
heating elements.
Duration, with 3 dashes
t_1 = 10 minutes
t_2 = target_time
t_3 = 4 minutes
Duration, with 2 dashes
t_1 = 10 minutes
t_2 = 0.5 x target_time
t_3 = 4 minutes
Duration, with 1 dash
t_1 = 10 minutes
t_2 = 0
t_3 = 4 minutes
Duration, with 0 dashes
t_1 = 4 minutes
t_2 = 0
t_3 = 4 minutes
NOTES
The “
target time
” stated in the table refers to the time specified in the annexed “PROGRAM TABLE” document.
In a standard program, e.g. with drying having t_target=25min, the total time of the phase is calculated as follows:
t_d = t_1 + t_2 + t_3 = 10 + 25 + 4 = 39minutes.
If the final temperature is below 40°C during the last phase of the washing cycle, step 1 is completely omitted, since
there is no need to expel steam: t_1=0.
Target temperature:
the temperature value in the program table, which refers to the temperature reached by the
monitoring probe TA in the drying duct. The temperature in the well during drying is about 30°C below the target
value. For example, for a drying program with T_target=110°C,
T_well ≈ T_target - 30°C = 110°C – 30°C = 80°C
.
SEPARATE DRYING PHASE
Users can also select a
SEPARATE DRYING CYCLE
by pressing the “
Drying Decrease
” button for 2 seconds: the
message “
PdrY
” appears on the display.
The drying time can still be adjusted as described above.
