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.
