Operation
RINSE-AID PUMP
Before you perform these adjustments, turn off the power supply.
This model has an automatic rinse-aid pump for use with a container of liquid rinse-aid. The rinse-aid pump is
a peristaltic regulated (looks exactly like the detergent pump) and can be regulated by a screw above and on
the right of the glass cover. The regulation can be from 0 lt/hour to 0,7 lt/hr.
The dozer is adjusted from the manufacturer’s premises at its maximum value for easy initial priming
and must be adjusted accordingly (depending on water hardness, water pressure, how dirty the dishes
are, and the detergent used).
For initial priming of dozer, during the initial filling of the wash tank, start by switching on machine normally.
While the wash tank is filling, during the initialization only, open and close the door in 5 second intervals. Be
careful of spraying water. Do this for about 10 times, and the rinse system will be primed. Empty wash tank and
fill normally. Operate 2 or 3 wash cycles and machine is now ready to be calibrated or ready for normal use.
To reduce (-) the amount of rinse aid, turn the center screw clockwise. To increase (+), turn counterclockwise.
Note: this is a 15 revolution adjusting screw to provide fine adjustments as required.
Hint to installing personnel: After priming system by operating machine through several cycles, rotate
adjusting screw gently to full closed position (clockwise) and adjust (counter-clockwise) about 7 full revolutions.
Empty wash tank and refill with fresh water. Operate for two or three cycles and verify concentration level.
Adjust dozer to achieve final desired results.
OPERATION
1. Check that the pump inlet filter has been placed in the correct position if it was removed for cleaning.
2. Check that the overflow stand pipe is inserted correctly in its outlet.
3. Close door.
4. Turn power switch to “ON” (switches should now illuminate.)
5. The dishwasher will fill automatically.
6. The booster indicator should come on to indicate that the inlet water to the rinse and fill system is being
heated to the required rinse temperature (usually 195°F / 91°C.)
7. When the booster water has reached the correct temperature, the corresponding light switches off and the
wash tank light comes on if the wash water temperature is not sufficiently hot (usually 165°F / 74°C.)
8. At initial daily start, allow about 10 to 20 minutes for machine to stabilize water temperatures to their proper
temperatures.
Note: After warm-up, one initial wash cycle should be performed to thoroughly mix soap and water
and be sure unit is fully warmed up and ready to wash properly.
9. After initial warm-up, when all heater lights are off, the dishwasher is ready to wash.
Note: If door is opened during operation, the safety control will turn off the timer. Washing or
rinsing will restart from beginning of wash cycle.
10. Open the door, insert the basket with the items (dishes, glasses, etc.) noting that heavy food residue
has been removed. (If the automatic soap injection system is not used, pour the proper amount of liquid
