OPERATING INSTRUCTIONS
INSTALLATION
Before proceeding with the start-up of the unit, verify the following:
1. The strainer is in place and is clean.
2. That the wash and rinse arms are screwed securely into place and that their end
caps are tight. The wash and rinse arms should rotate freely.
3. Verify all chemical levels for machine chemical feeder pumps are correct.
To energize the unit, turn on the power at the service breaker. The voltage should
have been previously veried as being correct. If not, the voltage will have to be
veried.
For the initial ll, close the door and ensure that the MANUAL switch light is not on.
Depress and hold the START CYCLE switch until the auto light comes on and then
release the button. For the initial ll, run the machine through 3 cycles to ll the tub
sump. The machine will run a partial cycle and ll to the bottom of the pan strainer.
Open the door and verify that the water level is correct.
NOTE: For the NOBLE UH30:
Ensure the orange/white wires at the heater contactor are connected properly. They
have been purposely disconnected at the factory to avoid damage to the heater
element when there is no water in the booster heater.
Hereafter, the water level is controlled by the timer that has been preset at the
factory. Verify that there are no other leaks on the unit before proceeding any
further. The wash sump must be completely lled before operating the wash pump
to prevent damage to the component. Once the wash tub is lled, the unit is ready
for operation.
The machine runs a complete cycle to drain and ll. If the machine is not allowed to
drain, the water will build up inside the tub. After the initial ll, the rinse water for the
current cycle will become the wash water for the next cycle.
Proper preparation of ware will help ensure good results and less re-washes. If
not done properly, ware may not come out clean and the efciency of the dish
machine will be reduced. It is important to remember that a dish machine is not
a garbage disposal and that simply throwing un scraped dishes into the machine
simply defeats the purpose altogether of washing the ware. Scraps should be
removed from ware prior to being loaded into a rack. Pre-rinsing and pre-soaking
are good ideas, especially for silverware and casserole dishes. Place cups and
glasses upside down in racks so that they do not hold water during the cycle. The
dish machine is meant not only to clean, but to sanitize as well, to destroy all of the
bacteria that could be harmful to human beings. In order to do this, ware must be
properly prepared prior to being placed in the machine.
