    DTX10 - DTX100 USER GUIDE Inspection and Installation PRIOR TO INSTALLATION OR START-UP OF DRYER, THIS ENTIRE MANUAL SHOULD BE READ AND UNDERSTOOD. Inspection All Dryers are tested and inspected at the factory prior to shipping. Inspect the dryer carefully upon arrival and note any damage on the freight bill.

Access ports should be provided upstream and downstream of the dryer for dew point, pressure, and temperature checks. Periodic checking of the dew point just downstream of the dryer is the best indication of whether the dryer is performing as expected.

  • Page 6: Safety And System Precautions

    DTX10 - DTX100 USER GUIDE Safety and System Precautions • Use EXTREME CAUTION when working in the vicinity of the dryer. • Relieve pressure before servicing dryer or associated equipment. • Disconnect power before servicing dryer. • Use ear and eye protection when in the vicinity of the dryer or exhaust ports, especially if the dryer is being operated without mufflers.

  • Page 7: Sequence Of Operation

    DTX10 - DTX100 USER GUIDE Prior to switching a freshly regenerated bed “on-line” to become the drying bed, it must be slowly pressurized from atmospheric pressure to line pressure. This step is called repressurization. Repressurization prevents bed fluidization (lifting) and associated dusting.
  • Page 8 DTX10 - DTX100 USER GUIDE STEP 2 - LEFT DRYING, RIGHT REPRESSURIZING While the left tower is still drying, Solenoid #4 will de- energize, relieving the control air signal on the right exhaust valve, returning that valve to its normally closed state. Closing this valve keeps air in the tower, al- lowing the depressurized part of the dryer to build up pressure or “repressurize”.

  • Page 9: Start Up

    DTX10 - DTX100 USER GUIDE Start Up Please read and understand the entire manual before operating the dryer. Check and read over wiring diagrams that pertain to your unit and make sure the correct power supply is connected, but do not energize circuit at this time. Provide proper short circuit protection. Follow all applicable codes.

  • Page 10: Operational Notes

    DTX10 - DTX100 USER GUIDE Operational Notes Never service the dryer or filters without first relieving pressure. Check all air connections for leaks and tighten as required. Downstream air leaks will affect dew point. Bypass air leaks will affect dew point. Only soft seat bypass valves may be used.

The sensor will also become saturated to atmospheric conditions if the air system is shut down and allowed to depressurize. Upon restart of the system, the dew point may appear to be poor, even though the dryer may be producing clean, dry air.

  • Page 14: Maintenance Program

    DTX10 - DTX100 USER GUIDE Maintenance Program Daily 1. Check dew point or humidity level if instrumentation is available. Any difficulty with the dryer will result in poor dewpoint performance. 2. Check for correct purge setting and air flow from purge exhaust.
