The operator’s responsibility does not end with e fficient production. The operator usually has the most daily contact with the equipment and intimately knows its capabilities and limitations.
• Shut off power to the dryer when it is not in use. T urn the switch to the OFF position, or unplug it from the power source. Maintenance Responsibility Proper maintenance is essential to safety. If you are a maintenance worker, you must make safety a priority to effectively repair and maintain equipment.
Chapter 2: Functional Description 2-1 Models Covered in This Manual This manual provides operation, installation, an d maintenance instructions for 1 5, 30 and 60 cfm dehumidifying dryers.

Safety Circuit Standards Safety circuits used in industrial systems protect the o perator and maintenance personnel from dangerous energy. They also provide a means of locking out or isolating the energy for servicing equipment.
Chapter 3: Inst allation 3-1 Uncrating the Equipment Dehumidifying Dryers are shipped mounted on a skid, enclosed in a plastic wrapper, and contained in a cardboard box. 1. Pry the crating away from the skid. Note: Remove the nails holding the box to the skid and lift the box off carefully; avoiding staples in the 1’ x 4’ wood supports.

3-4 Setup Procedures This section provides the procedures necessary fo r configuring your Dehumidifying Dryer. Configuration of your dryer includes checking for pr oper blower rotation, making dryer/drying hopper process air connections and the optional aftercooler (on 15 a nd 30 cfm models).
Drying Hopper Air Trap Considerations Our exclusive air trap assembly on the top of the drying hopper prevents am bient air from contaminating the material being dried .
trapped air from the system. Make sure the aftercooler has the proper supply water temperature. 6. Set the process set point on the temperature controller. 7. After the proper pre-drying time for the in itial hopper fill has elapsed, fully open the drying hopper slide gate.
Chapter 4: Operation 4-1 Controller Description and Operation Identifying Control Panel Indicator Lights and Switches for the Standard Controller Switches Main Power. This switch allows the dryer to receive power from the main power supply (3 phase only).
Optional Controller – Optional Three Phase Control Panel shown with Optional Dew Point Monitor Process Air Temperature Controller Our dryers use a microprocessor-based PID temp erature controller for maintaining process air temperature. The controller is a modular, self-contained unit you c an remove from the mounting housing.
Identifying Process Air Temperatu re Controller LED Indicators Indicator Name Description PV 8.8.8.8 Process Value Numeric LED During normal operation, the process value ( PV ) numeric LED indicator displays the process temperature at the To Process thermocouple.
Setting the Process Air Temperature When setting the process air temperature, consult with the resin manufacture for the recommended drying temperature. To change the process air temperature set point with the dryer running: • Press to raise the set point to the temperature you want.
Indicator Name Description preprogrammed by the operator. Proportional Band Mode (P) This setting controls the amount in which the manipulated variable ( MV) is proportionate to the deviated value or controller error.

Note: The dew point alarm monitors and indicates a deviation from the set point. 4-2 Dryer Operation Procedures Controller Operation 1. Turn the disconnect (if applicab le) on the control panel to the ON position. Power is applied to the voltage line fuses, line side of the control power switch.
4. If either the left or right bed safety temperature switch opens, a regen heater fault is generated. “HIGH TEMP” is displa yed on the relay screen. The alarm light is activated. 5. If the process temperature controller faults or the process heater safety switch opens, a heater fault is generated.
The following is a list of Alarm Display Messages which can be found on the relay screen: HIGH TEMP Temperature Controller Alarm and/or Regen Heater Temp Switch and/or Process Heater Temp Switch and/o.
Chapter 5: Maintenance 5-1 Preventative Maintenance Schedule The checklist below contains a list of items wh ich should be inspected and/or replaced to keep your Portable Drying/Conveying System operating at peak efficiency. Perform each inspection at the regular intervals listed below.
5-2 Preventative Maintenance This section describes maintenance procedures which will increase the longevity and efficiency of your dehumidifying dryer.
Cleaning with Compressed Air Blow clean, dry compressed air up and down the pleats, blowing out the filter from the inside out. Remove loose dirt fr om the filter with compressed air or vacuum from the outside. Caution! DO NOT clean/wash filter with water! After each cleaning: • Inspect the filter element.
WARNING! Handling desiccant material is HAZAR DOUS. Wear an N-100 type safety filter mask or equivalent to avoid prolonged breathing of desiccant dust. Wear safety goggles and gloves to avoid contact with eyes and skin. • Handle with adequate ventilation.

Replacing the Process/Regeneration Heater The dehumidifying dryers utilize a single-phase Ca lrod-type heater element. This heater element is mounted in the center compartment in the desiccant beds. Although the replacement procedure is the same for each heater, the wattage varies by model, voltage, temperature range, etc.
5. Disconnect heater thermostat safety. 6. Pickup and place the top casting in a safe place. 7. Pickup the desiccant can to reveal the heater. 8. Using a 1/8” Allen wrench, remove the four (4) 10-32 screws on the heater plate. 9. Remove the wires to the heater plate assembly being removed or replaced.
5. Visually inspect the coil for leaks, dirt, and ant sign of volatiles. 6. Blow the dust out, or if the coil is covered with plasticizer, steam clean it. 7. Place the coil back in its housing. Make su re the gasket is OK, replace if necessary. 8. Inset the four 10-32 bolts back in place.
Chapter 6: T roubleshooting 6-1 Introduction The utmost in safety precautions should be observed at all times when working on or around the machine and the electrical components. All normal trouble-shooting m ust be accomplished with the power off, line fuses rem oved, and with the machine tagged as out of service.
Alarm Message Cause Corrective Action Dryer Status The process temperature has exceeded the alarm set point. The process heater contactor has failed in the closed position.
Alarm Message Cause Corrective Action Dryer Status Limit switch may be out of position. Re-adjust the switch to make sure it trips when it is at the high position, and it does not touch the cam when it is at the low position. VALVE MTR The limit switch on the valve may not have been wired correctly.
