necessary. Make sure all the hose connections and all the components of
the dryer have proper seals on them (i.e. desiccant tanks, heater box, filters, after-cooler). Tighten the connections and replace any damaged seals.
Make sure the regeneration timing cycle matches the specs. If not, contact the Service Department.
Desiccant may be contaminated and blocking the air flow. Check desiccant, replace if necessary.
Make sure the process filter is clean. Clean or replace if necessary.
Double check the alarm set point is at 35° F. Check the positioning of the thermocouple inside the air inlet of
the drying hopper. The tip of the thermocouple should be centered in the tube, and not touching any metal part of the tube.
The drying temperature set point is lower than dryer capabilities. Check the dryer specs.
Make sure all the hose connections are tight. Make sure the regeneration timing cycle matches the specs. If
not, contact Service department.
The switch is indicating the incorrect desiccant tank is in regeneration. Check the wiring of the switch against the wiring diagram. Make sure all the wire connections are tight.
Limit switch may be out of position. Re-adjust the switch so it trips when it is at the high position, and avoids touching the cam when it is at the low position.
Limit switch may be faulty. Replace the switch and make sure the wires are connected correctly.
