Cooling & Heat Exchange ACN/DCN Oil-Air Coolers Installation Single pass ACN/DCN Oil-Air-Coolers Installation notes; space requirements and fitting instructions. When installing the cooler, please ensure that the cooling air can flow in and out freely. The distance from the wall (A) should be equal to or greater than the height of the cooling unit (see Figure 1). Ensure that no other currents of air interfere with the cooling air flow of ACN and DCN Oil-Air-Coolers. If the cooler is operated indoors, there must always be an adequate supply of fresh air to prevent any negative effect on cooling performance...
