The capture tank is furnished with a pump to transfer the fluid to adjacent containers supplied
by the customer. The transfer pump is capable of generating a maximum head of 16 feet.
The interconnecting piping should be sized as large as practical to minimize friction losses
and should be positioned in the container so as to avoid back flowing to the tank (siphoning).
The transfer pump will operate automatically when power to the control panel is turned
on
.
Please refer to the attached wiring diagram for details on wiring and the float switch control
logic. Normal operation is for the rising fluid to close the contacts of the float switch that
activates the pump.
Do not set the shutoff point of the switch too high or the freeboard
will be insufficient to handle a full load discharge from the Extractor resulting in tank
overflow.
PREVENTIVE MAINTENANCE
1.
Periodic inspection should be made of the balancing springs and the balancing spring
supports for breakage and spring tension. If adjustment is required, proceed as outlined
below.
Springs should be replaced as a complete set (4) in the event of any spring
failure.
2. On machines equipped with a motor cooling blower, the blower inlet screen must be
inspected weekly. If the screen is plugged with dirt remove it and simply clean it with
compressed air.
DO NOT ATTEMPT TO CLEAN THE SCREEN WHILE THE BLOWER
IS RUNNING AS DIRT WILL BE BLOWN INTO THE MOTOR!
Be sure to reinstall the
screen after cleaning or replace it if damaged. This keeps chips and debris out of the
motor windings.
3. All fasteners should be periodically checked for tightness.
4. Regularly inspect the rotating assembly for excessive wear, cracks and broken
components. Replace any suspect parts immediately.
5. Check all of the latches and lid attachments periodically to see that they function properly
and have not become loose or broken.
6. Never put feet or hands in the hand holes of the drum while the machine is running.
7. Always replace guards after repairing or checking the machine.
LUBRICATION
The motor spindle bearings are of the grease sealed type requiring no attention. The pivot
seat at the base of the motor should be lubricated with #30 SAE oil through the oil cup that
can be reached through the opening at the lower right front of the machine drum. Fill with oil
to the top of the oil cup and check the oil level weekly. Grease the lid hinge weekly.
