; When welding or brazing in or around this equipment, make sure VENTILATION is ADEQUATE . PROTECT adjacent materials fro m flame or sparks by shielding with sheet metal. An approved FIRE EXTINGUISHER should be clo se at hand and ready for use if needed.
Please read and use this manual as a guide to equipment safety. This manual contains safety warnings throughout, specific to each function and point of operation. Operator Responsibility The operator’s responsibility does not end with e fficient production.
• NEVER stand or sit where you could slip or stumble into the dryer while working on it. • DO NOT wear loose clothing or jewelry, which can be caught while working on a dryer. In addition, cover or tie back long hair. • Clean the dryer and surrounding area DAILY , and inspect the machine for loose, missing or broken parts.
Chapter 2: Functional Description 2-1 Models Covered in This Manual This manual provides operation, installation, and m aintenance instructions for 15, 30, and 60 cfm dehumidifying dryers.
2-3 Standard Features Mechanical Features • Dual desiccant beds • Electrically-actuated air valve • 13X Molecular Sieve • Single regenerative process blower • Drying temperature range of 180ºF to 250ºF (82 ºC to 121ºC). • 2.5” hose connections Electrical Features • Process thermocouple to be connected to drying hopper air inlet.
2-4 Options Options marked with “*” indicate options that can be factory installed or retrofitted in the field. • * Process temperature up to 400ºF (204º C) or below 180ºF (82ºC), including aftercooler with dryer and silicone insulated delivery hose.
Every effort has been made to incorporate these standards into the design of the drying system; however, it is the responsibility of the personnel operating and maintaining the equipment to familiarize themselves with the safety procedures and the proper use of any safety devices.
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 lif t the box off carefully; avoiding staples in the 1’ x 4’ wood supports.

3-4 Setup Procedures This section provides the procedures necessary for configuring your portable drying/conveying system. Configuration of your unit includes checking for proper blower rotation and installing the optional aftercooler (on 60 cfm models).
NOTE: If the Aftercooler is used as a plasticizer trap, the water temperature of 50°F or lower is recommended. 3-5 Initial Start-up Pre-Startup Checks ; Check the process and return hoses for tight connections. ; Check all companion equipment, such as the drying hopper; verif y that the loading system is ready for operation.
Chapter 4: Operation 4-1 Start-up 1. Turn on (energize) the disconnect switch in your power drop, and then turn on the one on the dryer. 2. Turn the system ON/OFF switch to ON to energize the display panel. 3. Close the slide gate at the bottom of the drying hoppe r.
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.
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. It also lists parameters during setup and error messages if any errors occur.
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.
Adjustment Level Indicator Name Description Auto-Tune Mode (At) See Page 19 of Chapter 3 for instructions on how to Auto-Tune your dryer. Note: Although the controller is calibrated at the factory, the manufacturer recommends that the unit be Auto-Tuned prior to dryer startup.
Entering Operating Parameters to Select Modes To enter the display: 1. Press the Mode Display key to view the Run/Stop & Alarm 1 Modes. 2. Press and to set the higher or lower the values of the param eter or turn that function On or Off. The SV readout displays the different values for the parameter within a mode.
Process Air Dew Point Display Optional The Process Air Dew Point meter indicates the cu rrent process air delivery moisture content. Standard dryers use a microprocessor-based controller for displaying dew point air temperature. The controller is a modular, self-contained unit removable from the m ounting housing.
Redundant Safety Controller Display Optional The Redundant Safety Controller limits the pr ocess air temperature from exceeding the upper temperature range set by the E5CN Temperature Controller. Standard dryers use a microprocessor-based controller for limiting the process air temperature.
Entering Operating Parameters to Select Modes To enter the display: 1. Press both the Up and Down keys for three seconds from the home page. The word SEE will appear in the upper display and PAGE will appear in the lower display. 2. Press the Advance Key to move through the param eter prompts.
4-3 System Operation Procedures Controller Operation (Without Optional Alarm Horn & Reset Button) 1. Turn the disconnect on the control panel to the ON position. Power is applied to the voltage line fuses, line side of the control power switch and the temperature controller.
5. If the 1TCU (E5CN) controller faults, the opti onal redundant high temperature safety device opens, or the process heater safety switch opens, a heater fault is generated. “ HIGH TEMP ” is displayed on the relay screen. The alarm light is activated.
a. The valve motor rotates until the cam switch makes 2 transitions. b. If the cam switch does not make a transition within 10 seconds, a valve motor fault is generated. “VALVE MTR” is displayed on the relay screen, the alarm horn and light are activated.
Reset the motor overload and turn the Off-On-Start switch to the START position to restart the dryer. 7. The valve position limit switch enables the right bed heater and provides an input signal to the programmable relay when actuated by the cam lobe.

4. Turn the system ON/OFF switch to OFF . 5. If needed, empty the drying hopper. 6. For maintenance or a long term shutdown, open (de-energize) the electrical disconnects at the dryer and at the power drop.
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.
Vacuuming Try vacuum-cleaning a soiled filter first. Vacuuming removes most large particles and surface contaminants, and may suffice for the firs t time you clean a filter. Use a commercial- duty (recommended) or household vacuum cleane r. Vacuum the filter from the air intake (dirty) side only.
5-3 Corrective Maintenance This section provides you with the informati on necessary to correct or repair any issues which might appear during the norma l operation of your dehumidifying dryer. Although we have listed how to perform these procedures, it is recommended that you call the Service Department to have any in-d epth maintenance performed.
