Water Fill Process; Heating Process; Cooldown Function - Primus RF6 Programming Manual

By pressing the TURN DRUM push button the drum will turn automatically to the next drum
compartment.
When the drum has stopped and the indication light UNLOCK DOOR is eluminated, press the
UNLOCK DOOR button.
Now you can unload / load the drum at the next compartment.
On the small MB washing machines after closing and locking the Outer Door at the Hygienic Side
automatically the wash computer switches the door and turn drum control to the Dirty Side.
For the big MB washing machines with multiple drum compartments, you have to press the "SWITCH
SIDE" button to switch over from Hygienic to Dirty Side.

6.12. WATER FILL PROCESS

Depending the water temperature the cold and hot inlet valves will be opened.
The water level is measured by an electronic water level sensor.
If the Temperature Balance function is enabled, the Full Control Wash Computer will control the
water temperature until the target temperature is reached. For Hot wash programs, extra heating
will be required after the fill process to reach the programmed hot water temperature.
In the standard wash tables you will find a Normal Low and Normal High water level.
These are the standard water levels :
- The Normal Low water level is used for the Prewash, Wash and Soak sequence.
- The Normal High water level is used for the Rinse and Final Rinse sequence.
The water level can only be programmed between two limits:
- The lower limit is above the heating elements and the temperature sensor.
- The upper limit is below the overflow hole.

6.13. HEATING PROCESS

When "No Wait for Temperature" (No Wait for Heat) is selected :
- The machine will heat until the time of the specific wash step is over or if the programmed
temperature was reached.
- Even if the programmed temperature is not reached, the program will start the next sequence if
the time of the sequence is over.
When „Wait for Temperature" (Wait for Heat) is selected:
- The machine will heat until the programmed temperature is reached. The programmed time of the
wash sequence will only start counting down from the moment that the target temperature was
reached.
ATTENTION !!!
!
WHEN THE MACHINES DO NOT HAVE ELECTRICAL OR STEAM HEATING NO „WAIT FOR
TEMPERATURE" SHOULD BE SELECTED IN THE INITIALISATION MENU.

6.14. COOLDOWN FUNCTION

AUTOMATIC COOLDOWN : this function avoids thermal shock in the washing machine.
For Hot washes above 65°C, Cold water is added at the end of the step.
PROGRAMMED COOLDOWN : this function is recommended to avoid the shrinking of the garments.
Water is drained and cold water is added bit by bit. The temperature of the water in the tub will
decrease slowly as a function of the programmed Cool-down Sequence (temperature and time).
