  • Page 4: Section 1 Installation And Inspection

    SECTION 1 Installation and Inspection 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. Uncrate and inspect for concealed damage. File claims with the carrier immediately and notify the AIRTEK service department.
  • Page 5 5. IMPORTANT! Bypass piping is necessary. A bubble tight valve should be used for bypass around filters and dryer for servicing. Make required electrical connections to control box. Refer to applicable drawings. NOTE: Customer to provide short circuit protection for dryer. Access ports should be provided upstream and down- stream of the dryer for dew point, pressure, and temperature checks.

  • Page 6: Section 2 Safety And System Precautions

    SECTION 2 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: Section 4 Sequence Of Operation

    Important! The dryer is designed to remove only water vapor. You might see a small amount of condensate forming at the exhaust due to the Joule-Thomson cooling effect created by the depressurizing air. 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.
  • Page 8 Step 3 is the reverse of step 1. Solenoid #1 is energized, providing control air to and opening the left exhaust valve. Solenoid #2 is energized, providing control air to and closing the left inlet valve. Solenoid #3 and #4 are de- energized.

  • Page 11: Section 5 Start Up

    Section 5 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 12: Section 7 Shutdown Procedures

    Exhaust valves and/or exhaust mufflers may have to be cleaned due to dusting in shipping and start- A desiccant dryer should never be suddenly pressurized or depressurized. This will cause fluidizing and dusting of the desiccant bed. After start-up, some dusting may occur. This will diminish with time. Some dusting may occur with normal operation.

  • Page 13: Section 8 Demand Cycles

    Depressurization Open bypass piping. Close outlet isolation valve. Close inlet isolation. Allow dryer to run. The normal cycle will allow both tanks to blow down and depressurize. Disconnect power. With the “Basic Filter Package” dryers, open manual ball valves on filters to allow full depressurization.
  • Page 14 Annunciator. The Variable Cycle Switch must be set to the 100% load setting and the Demand Control switch ON, for the Pro Purge to work! If the dryer is maintaining a good dew point AFTER the first five minutes of drying, the Pro Purge will override the fixed cycle and keep the current tower on-line until it is saturated to design loading (switch point value), usually -40°.
  • Page 15 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. Although the probe can be exposed to occasional, brief periods of liquid saturation, it can not be exposed to continuous wet conditions.

  • Page 17: Section 9 Maintenance Program

    Section 9 Maintenance Program Daily 1. Check dew point or humidity level if instrumentation is available. Any difficulty with the dryer will result in poor dew point performance. 2. Check for correct purge setting and air flow from purge exhaust. 3.
  • Page 18 Desiccant Replacement CAUTION: Activated Alumina Desiccant dust is considered a nuisance dust. Proper precautions should be taken. Refer to “Material Safety Data Sheet”. Remove pressure and power from dryer. Open drain ports on bottom of tanks. Catch desiccant in suitable container. Close drain ports and open top fill ports. Refill with recommended type, size and quantity of desiccant.
