Note: A water level fill adjustments and/or the condition of the

water extractor pulp usually requires some time before

the system responds to a change.

Make small incremental changes to balance the waste

handling system and closely observe operation response.

Read the Waste Handling Precautions on page 6 before

processing waste in the system.

1. Close the pulper drain valve and the water extractor drain/

overflow handle. Place a refuse container under the water

extractor discharge chute.

2. FOR OPTIONAL FEED TROUGH CONFIGURATIONS ONLY:

Perform Step No. 1 above and open the recirculating pump

feed trough valve half-way. Adjust this setting to achieve

the slurry water flow best suited to the waste being processed.

3. Make sure the main water and power supplies are on.

4. Turn the remote control cabinet breaker switch on. Wait for the

pulper to fill, then push the Start push button on the water

extractor.

5. Check the water level in the pulper tank. The water must be

rotating in a counter-clockwise direction and have a whirlpool

appearance. The pulper water level is too high if the whirlpool

effect is not observed.

6. There should be a pulsating sound to the water as it rotates in

the pulper tank.

7. Begin feeding a mixture of food waste, paper, and cardboard

into the pulper. Cardboard boxes must be reduced.

8. The pulper will shudder when heavy items such as cardboard

are fed into the tank. This is normal.

9. Pulper water should begin to turn a milky color. In the water

extractor, a wet pulp should begin to appear around the

screen.

10. A semi-dry pulp will appear at the top of the water extractor

and be forced into the discharge chute by the wiper blade.

There are 3 main factors that affect the dryness of the pulp:

1. The ratio of food waste, water, and paper in the pulper

2. How finely the waste is shredded in the pulper tank.

3. The cone setting at the top of the water extractor.

11. The inter-relationship of these 3 variables makes it impossible

to provide a definite procedure for adjusting the waste handling

system. Observation, careful adjustment, and consultation

with the end-user is the only way to reach a favorable result

when balancing the system.
