Cleaning the Aftercooler Coils

If you have the optional aftercooler, you need to clean the cooling coils to keep them working efficiently. See Appendix C for details.

Cleaning the Precooler Coils

If you have the optional precooler, you need to clean the cooling coils to keep them working efficiently. See Appendix E for details.

Inspecting Hoses and Gaskets

Loose or damaged hoses and gaskets can allow moisture to seep into the closed- loop drying system.

1Follow the hose routing of all the hoses within the dryer and inspect all hoses, clamps, fittings, and gaskets.

2Tighten any loose hose clamps or fittings.

3Replace worn or damaged hoses and gaskets.
