Sterling SDA 1000-5100 specifications Cleaning or Replacing the Regeneration Filter

Page 43

Use the following procedure to clean or replace the filter cartridges:

1.Turn off and/or lock out electrical power to the dryer.

2.Remove the hand knobs or clamps securing the filter access cover and remove the cover.

3.Remove the nut on the center-retaining rod to remove a filter cartridge.

4.Vacuum, blow out, or wash the filter.

5.Inspect the filter - a damaged filter should not be reused. Check the following:

„Hold a light bulb behind the filter element to find holes, tears, fatigued paper or residual dirt.

„Inspect the end plates—damage here could allow air to bypass the filter.

„Look for rust on the end plates and metal core—rust particles could flake off and contaminate the dryer and resin.

„Check the gasket for damage—a damaged gasket will allow contaminants into the process. Replace if needed.

6.Return the filter cartridge to its original position and tighten the nut on the center- retaining rod to secure the filter cartridge.

7.Secure the filter access cover with the hand knobs or threaded fasteners.

Cleaning or Replacing the Regeneration Filter

Large dryers are equipped with a filter in the regeneration air loop located at the back of the dryer. Regular filter cleaning will keep your dryer operating at peak efficiency.

Caution! Operating the dryer without the regeneration air filters installed will void the warranty.

1.Turn off and/or lock out electrical power to the dryer.

2.Remove the knob securing the filter.

3.Remove the filter from the post.

4.Vacuum or carefully blow out the filter with compressed air. If the filter is worn or can't be cleaned, replace it.

5.Slide the filter back onto its post and tighten knob back on the filter.

Calibrating the Dirty Filter Alarm

Your dryer may be equipped with a Dirty Filter alarm. When the alarm sounds, it is time to clean or change the filter. The Dirty Filter alarm is tested and calibrated at the factory, but it can be adjusted in the field. Be sure that your filter is clean, and use the following procedure to calibrate the alarm.

1.Remove the process air return filter element from its housing.

2.Block off approximately 50% of the filter’s surface area to simulate a dirty filter.

3.Reinstall the cartridge and secure the cover.

4.While the process blower is operating, adjust the trim screw on the differential pressure switch until the alarm light just comes on.
