Air/air heat exchangers External circuit Flow and siting conditions Air/air heat exchangers in the external circuit should have a distance of at least 200 mm from a wall and from one another (air inlet and outlet openings). If this distance cannot be met, air baffle plates should be used. Siting options Wall-mounted heat exchangers may be mounted on the rear panel, side panels or door of the enclosure. Distance from the wall at least 200 mm Free air circulation 200 It is important to ensure “even” air circulation inside the enclosure. Air inlet and outlet openings in the internal circuit must on no account be obstructed by electrical installations. This would prevent air from circulating inside the enclosure. Under such conditions, the capacity of the device would not be adequately utilised. A clearance of > 200 mm must be guaranteed. Note: Wall-mounted cooling units should never be fitted directly behind the mounting plate. Active power components are located on the front of the mounting plates. The heat exchanger would then operate in its own air short-circuit. If it is impossible to install the device any other way, appro- priate air baffle plates should be used, and air inlet and out- let openings should be provided in the mounting plate.
