Installation, Operating and Maintenance Instructions
for KTM "EC" & "ECT" Type Dust Collector

The "EC" / "ECT" unit is completely pre-assembled at our Brampton facility. Simply stand the unit up in the required location.

Connect the ducting to the unit inlet.

A licensed electrician is required to connect the motor, switch and electrical supply line. Run the fan and check to ensure the rotation turns toward the outlet (see diagram). The fan direction can also be observed by viewing the rotation of the motor's rear cooling fan.

Connect the single-phase plug from the solenoid switch to your power supply.

Connect a compressed air supply to the coupling on the side of the "EC" / "ECT" unit. This air should be clean and dry, and the system requires 80 to 100 P.S.I.

With the fan running, push the green button on the side of the unit and the solenoid valve should pulse a jet of compressed air back through the filters. This pulse is easily recognized as it feels and sounds like a mini explosion within the unit.

Measure the amps on the fan motor. They should not exceed the full load running amps. If the amps are exceeded contact Kraemer immediately as the motor will overload. We would then need to increase the resistance on the system.

The unit is now ready for operation.

Operating Instructions

Before starting the fan motor, the access door must be closed and the connected ducting must be fixed in position on the dust collector inlet.

Start the fan/motor using the switch provided and plug the electrical power cord to the power source.

Ensure that the compressor is running and connected to the compressed air coupling on the "EC" / "ECT" unit.

The unit is now operational.

The cleaning pulse should be used periodically during the day depending on how much work is taking place.

To activate the cleaning pulse, push the green button on the side of the unit. This sends an electrical signal to the solenoid which opens the diaphragm valve and allows the compressed air in the storage tank to pulse through the filter cartridges, reversing the flow for a fraction of a second. The pulse dislodges particles of dust in the pleats of the cartridge.

Pulsing should be done while the fan is running. If the fan is off the dust may blow back through the openings on the unit. There is a blow back damper on the inlet and the unit should be fairly airtight so this pulsing can be done with the fan off. The frequency of the cleaning will depend largely on how much work is being done. Once every hour should be sufficient under normal circumstances. If the operator notices that the suction at the machine is dropping off, then the filters are contaminated and the pulse should be activated.

The dust drawer should be checked periodically and emptied if necessary. To remove the dust drawer, simply turn the unit off, undo the two wing nuts on the front and slide it out to empty. To replace the drawer, reverse the procedure.

It is advisable to pulse the filters two or three times at the end of a shift and then switch the fan off immediately. This will allow the loosened dust particles to settle in the dust drawer without being drawn back into the filters by the fan exhaust.

Maintenance Suggestions

The dust drawer should be checked and emptied on a regular basis. The frequency of this step will depend on the shifts and the volume of dust.

The condition of the filter cartridges should be checked regularly. To do this, open the access panel on the front of the housing. If the compressed air is used regularly to clean the filter cartridges, they should be fairly clean. Check for tears or holes in the pleats and also for dust plugs between the pleats. If the cartridges are dirty, remove them and clean with compressed air. When necessary, or if damaged, they can be replaced.

To remove the cartridges, once the access door/panel has been opened, remove the two bolts located at each side of the dust collector at the bottom of the filter holding frame. These bolts hold the filter frame at the correct height against the angle iron stops. Now loosen the four nuts on the bottom of the threaded rods. These nuts are located below the retaining rings under the filter cartridges. Once they have been loosened, the cartridges and rings will drop down slightly allowing the cartridges to slide off the retaining rings and be removed via the access door/panel.

To replace the cartridges, simply reverse the procedure, ensuring that the cartridges are seated properly on the rings and that the sealing gaskets on top of the filters fit snugly against the bottom of the hole sheet. As the four nuts on the rods are tightened, the seals are squeezed. When the two bolt holes on the sides line up, the tension is correct.

Replace the door/panel and check the door seals to ensure an airtight fit.
