Switching on the heat exchanger
1. Always wear protective gloves.
2. Open the directional control valve on the heat exchanger (position I) → red marking.
The oil/compressed air heat exchanger is incorporated into the compressor oil circuit. Com‐
pressed air fed through the heat exchanger is reheated by the hot cooling oil from the com‐
pressor. “Condensate-free and warm compressed air” is available from the compressed air dis‐
tributor.
