3.) Installation Instructions

3.1 Location

The disintegrator can be placed in an office area within six feet of a wall receptacle with a dedicated

line. It is recommended that the machine be three to four inches away from the wall for proper

ventilation.

1) Place vacuum cabinet next to the disintegrator cabinet (on the left side) so the handles are next to

each other. Open doors on the cabinets and feed vacuum hose through hole in the bottom of the

right side of cabinet and connect to the transition in the disintegrator cabinet.

2) Plug vacuum cabinet into the back of the disintegrator cabinet. For the DS-200, the shredder will

be plugged in when received.

3.2 Electrical Wiring

• The machine includes an appropriate power cord and male plug. The unit is activated by a top

mounted selector switch with indicator light.

• Access to the cutting chamber for service is provided by the main cabinet door. A safety limit

switch activated by the main door prohibits operation when door is open.

Note: Some motors have manual overload reset button on motor, others are automatic.

Each machine will be clearly marked.

• If for any reason the machine is rotating in the wrong direction, remove metal plate on

motor and change leads as shown on plate diagram.

Note: Motors are normally dual voltages, 115/230 but can only be operated at the specific

voltage as wired at the factory. If voltage change is required in the field, contact factory for

proper instructions.

All electrical schematics and diagrams are available as a PDF upon request. Contact SEM for more

details.

3.3 Electrical Installation Options and Power

• Must be completed be a licensed electrician, see table below for plugs supplied with machine.

• Provide an appropriate receptacle with a cord and hang from a power disconnect switch.

• Provide an appropriate flanged receptacle and mount to a power supply.

4.) Operating and Troubleshooting

Please read this section carefully. Most problems occur during the first hours of operation. Most

problems can be eliminated by careful review of the operating, maintenance, and recommended

service instructions.

• The disintegrator has been shipped complete, tested, and is operational when received.

• The disintegrator requires a dedicated line equipped with an appropriate receptacle. (See

section 3 for more information.)

• Once positioned, verify vacuum is connected and all access points are closed. Test by turning the

selector switch to the full right START position and releasing. The unit will start and will

illuminate the green operating lamp.

• The disintegrator was designed to destroy plastics, film, and light volumes of paper products. As

with any type of office machine, it can be overloaded or jammed if overfed. Product destruction

rate depends on the material, size, and desired particle size. When feeding, the concept of less

is more is applicable. Feeding the unit less volume more often will result in better feed rates and

reduced operating costs.

• All disintegrator units are equipped with timed shutdown to help prevent jamming of the

disintegrator. When selector switch is in the OFF DELAY position, the disintegrator will run for

an additional 60 seconds to clear the chamber. This will help to prevent jamming of the unit

which would require some disassembly to gain access to the cutting area.

Important:

If you overfeed the disintegrator or have an emergency and need to shut down the machine, open the

front door of the disintegrator cabinet.

Warning:

Opening the front door to bypass the timed shutdown can result in a jammed cutting chamber or

damage to the cutting chamber.

semshred.com | 508.366.1488

4.1 To Clear a Jammed or Locked Rotor

1. Make sure selector switch is in OFF position.

2. Unplug power cord.

3. Open front door of disintegrator cabinet.

4. Remove plate on front hopper to access the cutting area using a flathead screwdriver.

5. Remove loose product.

6. Rotate rotor counter clockwise by means of the drive belt by hand to clear clogged material.

To restart:

7. Re-secure front hopper plate.

8. If necessary, reset circuit breaker switch or motor contactor, located on the control panel.

The lower left breaker should be up and all contactors and overloads on lower right should

be in vertical positions.

9. Re-plug power cord.

10. Close main door.

11. Turn selector switch to ON start position.

NOTE: Repetitive jams also can be a result of knives that require sharpening. If machine has no

power, reset circuit breakers on electrical panel located behind the hopper.

semshred.com | 508.366.1488

5.) Important Feeding Information

1. Before introducing any destruction material into feed slot (shredder or disintegrator), the

disintegrator and its vacuum must be turned on and operating. The material collection vacuum

must be checked periodically and emptied for the continued operation.

2. Destruction Material: This disintegrator is capable of processing a variety of materials safely and

effectively. Products that can be destroyed include products with light metals, plastics, and paper.

Listed below are products tested. If you are trying to destroy anything that is not listed below and

would like to verify that it is acceptable, contact SEM customer service at 1-800-225-9293 before

use.

3. Paper Destruction: The disintegrator is not a shredder but a rotary knife mill, which dictates how

the unit is fed and the rate at which it can be fed. Rule of thumb is less is more, which creates

steady output without overfeeding. Feed rate for paper is 4-5 sheets approximately every 10

seconds.

4. When destruction is complete, allow the disintegrator and vacuum to operate an additional 60

seconds after the last feed of material. This will prevent build up in the cutting area and

evacuation line, ensuring proper operation for the next user.

5. Vacuum Collector as with a conventional shredder. The disintegrator’s waste collection bag must

be periodically emptied for proper operation. Bag capacity is 35 gallons or approximately 2000-

2,500 sheets (four-five reams) of paper.

Note: For optimal sound reduction, close feed door after inserting documents or other materials.

Feed rates for other materials:

• CD ROMS at 3-5 per feed approximately every 15 seconds.

• Floppies at 3-5 per feed approximately every 20 seconds.

• Zip disks at 1-2 per feed approximately every 35 seconds.

• Audio cassettes at 1 per feed approximately every 30 seconds.

• Key tape strips up to 10 inches in length, 6 per feed lot.

Note: If shredding magnetic tape, mix with paper.

6.) Maintenance

6.1 Changing the Waste Collection Bag

Ensure that the power is off before attempting to change the waste collection bag located in the left

cabinet.

1. Open the door.

2. Reach inside and locate the snap ring around the inside rim.

3. Pull the tab on the snap ring inward and pull down with the bag to remove.

4. Place the snap ring over the top of the plastic bag and fold over the bag approximately three

inches.

5. Insert the snap ring with the waste collection bag into the bottom of the housing at an angle.

6. Pull down on the ring to make sure it seals in the rim of the housing.

6.2 Belt Adjustment

IMPORTANT: Belt should be checked and tightened if required after first two (2) days of operation.

After that, check monthly.

9.) Torque rotor knives to 50-55ft./lbs. Requires torque wrench and 5/16” Allen drive socket bit.

10.) Set clearance between rotor and bed knives to .001” using adjustment screws and a feeler

gauge, rotating the knives in reverse (clockwise) so “flat to flat” contact will not cut feeler gauge.

• Requires 7/16” wrench and .001” feeler gauge.

• Process will need to be repeated until proper clearance is achieved.

• You will hear a light knock while spinning the rotor when one or two rotor knives

meet the feeler gauge. This indicates proper clearance.

o There should be little resistance, just a noise.

o If the rotor stops, there is too little clearance.

o The knocking only occurs on the longest of the three rotor knives.

Occasionally it will occur for two knives.

• Check clearance in front of each bed knife bolt. The knocking should occur either in

the middle OR on the two outside bed knife bolts.

• Double check clearance after tightening bolts as gap should be checked on each

knife on rotor and across the whole surface of each knife.

11.) Torque bed knives to 45-50 ft./lbs.

• Requires torque wrench and 5/16” Allen drive socket bit.

• Torque wrench should not be used as a socket wrench and should be calibrated to

ensure proper tightening to avoid damage. SEM offers a complete toolkit for this

system.

• Double check knife clearance after torqueing bolts.

12.) Attach front and rear deflectors as shown with six 5/16-18” x 1 1/4" hex bolts and 5/16” lock

washers. Requires 1/2” wrench.

13.) Do a final check of bolt torques, assembly bolt tightness, and knife gapping.

Warning: Failure to sharpen or replace knives will result in excess dust, frequent jamming of

STAGE 2 chamber, reduced throughput, excess vibration, and increased noise throughout the

device.

Re-sharpening: Knives can be re-sharpened 2-3 times provided they are not significantly damaged or

worn. Knives must be sharpened as a complete set (2 bed knives, 3 rotor knives). Contact SEM

customer service at 1-800-225-9293 for details or for replacement knives.

Measuring the spare knives:

1. Place knives flat, back-to-back.

2. Measure from cutting edge to cutting edge.

3. If the measurement is below the minimum, then

the knives cannot be used and must be replaced.

6.5 Electrical Panel

The electrical panel is located in the main cabinet, behind the hopper.

Accessing the electrical panel:
