6. Once the machine is “loaded” the operator breaks the infra-red beam to close the door.
The display shows Shut
7. When the door is fully closed 2 GREEN LED’s will flash in the infra-red sensor area for 8 seconds to
advise the user to break the beam again to start a cycle.
The display shows rdY
If the 8 seconds has elapsed the flashing LED’s will stop and the unit will not start for a cycle. The
operator has to repeat the process from Step 5 (or press manual start).
Note: If this occurs the beam must be broken twice.
Note: On 10A models if the steam generator temperature is not at 90°C after the beam has been
broken or the manual start button pressed. The display will show “CYCL”, the green LED’s
will stop flashing and stay on. When the steam generator had reached temperature the
display will show rinS the wash cycle will start automatically.
8. Once a cycle has been initiated the elements are turned on in the steam tank to start heating the
water.
The wash pump is turned on for 10 seconds for the initial wash.

12. Rinse pump comes on for 10 seconds to rinse detergent from items
The display shows rins
13. Once the wash cycle is complete the display will flash 90 (indicating 90°C). This is the critical
temperature that must be reached before the disinfection cycle can commence. At this point the fill
solenoid is disabled and will not operate unit Step 12.
14. The elements in the steam generator heat to produce steam, which is directed into the wash chamber
raising the internal cabinet temperature above 90°C.
15. Once the internal cabinet temperature has reached 90°C the disinfection cycle will commence. This
display shows the actual cabinet temperature.
16. All 3 elements on 20amp models and all 2 elements on 10amp models will continue to heat during the
disinfection cycle until the internal cabinet temperature reaches 91°C.
17. At 91°C one element will turn off and at 92°C another element will turn off, on 20amp models, on
10amp models at 91°C one element will turn off. One element will remain on until 15 seconds before
the end of the cycle. If the internal cabinet temperature falls below 92°C the second element is
turned back on the third respectively if the cabinet temperature falls below 91°C.

Note: Regardless of element combinations 15 seconds before the end of the cycle ALL elements
will turn off. This is to overcome the effects of overshoot in the steam generator producing
steam at the end of the disinfection cycle.
18. The maximum time allowable for the disinfection cycle is 10 minutes. If this time is exceeded then the
machine will go to fault and elements turn off.
19. After the disinfection cycle is complete the cooling solenoid will turn on for 15 seconds. This will cool
down the surface temperature of the utensils and make them safe to handle.
The display shows cool. This water is direct from the mains.
20. At the end of the cool down rinse, the display shows end. This will be displayed until the door is re-
opened.
21. If not used the unit steam generator temperature will be kept at the temperature of 85°C-90°C for a
period of 15 minutes. If the unit is still not used it will enter into idle mode and the elements will only
come on at 50°C and rise to the temperature of 90°C repeatedly until the cycle is started again.
