1. Turn on the unit with the Switch on the control panel. See FIGURE 4 on page 6. 2. If, after the unit has warmed up, you don’t hear the fan running, there is likely not enough pressure to turn on the pressure switch. Turn off the unit and the compressor. Close the Air Inlet (#6). Then, turn the Air Dryer back on and it will build up pressure in a few minutes. Open the Air Inlet (#6). Turn on your compressor and let air in slowly at first. During operation, dry air will pass through the unit to the tool or application. 3. When you are finished, stop the air compressor first. Continue to run the Air Dryer until all of the compressed air runs through the system. 4. Turn off the Air Dryer. Note: If the Air Dryer stops and the Problem Light (See FIGURE 4 on page 6) goes on, the unit is running at too high of a temperature or pressure. Let the unit cool. Unplug the Air Dryer. Open the side panel (See FIGURE 3 on page 6) and push the reset button on the Pressure Switch (#14). See the Assembly drawing on page 10. Plug in the unit and restart. If the Problem Light stays on, or comes on continually, take the unit to an authorized service technician. Troubleshooting Warning!! Repairing this unit (other than trying to reset the Pressure Switch (#14), as mentioned above) should only be performed by an authorized service technician. Problem 1: Unit shuts off by itself. Reason: Temperature or pressure is too high or fan is overheated. Or, the Condenser (#11) is dirty. Solution: Reset pressure switch as described in the note above, or clean the Condenser (#11) as described in Maintenance on page 8. Problem 2: No power light when the unit is on. Reason: Loose connections at wiring panel. Solution: Check the connections and tighten. Problem 3: Unit won’t cool/dry air. Reason: Water in the refrigeration unit because of: Auto drain blocked, bad valve, bad connection to capacitor, bad capacitor, bad fan unit, low air pressure. Solution: Clean auto drain and tube, replace valve, check capacitor connection, replace capacitor, replace fan unit, turn up air pressure on compressor. Problem 4: Unit buzzes and won’t operate. Reason: Bad capacitor. Solution: Replace capacitor. Only done by a qualified electrician or service technician. Problem 5: Fan isn’t working at the correct temperature and pressure. Reason: Bad fan bearing, bad fan capacitor, or bad temperature switch. Solution: Replace fan bearing, fan capacitor, or temperature switch. Only done by a qualified electrician or service technician. Problem 6: Pressure on the inlet or outlet valves increase for no reason. Reason: Bad internal pressure valve. Solution: Replace internal pressure valve.

Reason: This may be caused by the formation of ice inside. Solution: The Hot Gas Bypass Valve (not shown in the Parts List or Assembly Diagram) needs to be adjusted. This adjustment should only be done after consultation with our technical support service at: 1-800-444-3353. Maintenance Note: Maintenance must be performed by an authorized service technician. Never attempt to adjust the temperature; this adjustment should only be done by an autho- FIGURE 5 rized service technician. 1. See FIGURE 5. Periodically clean the Condenser (#11). Use a dust collector and an air gun to clean dirt and debris. Be careful not to get too close to the unit with high pressure as you will damage the unit. If grease or oil are built up and won’t blow off, wash it off with a mild detergent. FIGURE 6 Note: The internal parts illustrated for step 2 below Strainer are a guide for the authorized service technician. They cannot be ordered Seal separately. Only the parts on the parts list on page 9 can be ordered. Screw 2. See FIGURE 6. Washing the auto drain. To wash the auto drain, close the 1/2 ball Filter Valve on top of the drain. Pull the manual Seal drain shaft handle to empty the water. Take Float Ball apart the drain and the fixed screw. Clean the strainer from inside to out. Take apart Valve the manual drain shaft and the seal end cap. Take off the float ball and valve seat. Clean Seal Spring each component and reassemble.
