In case of unauthorized modifications done by the user Bühler Technolo- gies GmbH can not be held responsible for any damage, –... -
Page 6: General Hazard Warnings
2.2 General hazard warnings The equipment must be installed by a professional familiar with the safety requirements and risks. Be sure to observe the safety regulations and generally applicable rules of technology relevant for the installation site. Prevent malfunctions and avoid personal injuries and property damage. The operator of the system must ensure: –... -
Page 7: Transport And Storage
3 Transport and storage Only transport the product inside the original packaging or a suitable alternative. Ensure secure fastening and mooring. Air coolers have M8 or M10 eye bolts at the top of the cooler housing for transport. Please note, due to the variety of versions the mounting bracket is not located at the centre of gravity and the cooler may swing when hoisted. -
Page 8: Installation And Connection
4 Installation and connection 4.1 Requirements to the installation site Aggregate The aggregate must be set up to allow for unobstructed air flow and adequate room for maintenance/repairs. When installed outdoors, be sure to consider the motor protection rating (standard: IP 55) and ensure adequate protection from the weather. Air cooler The cooler must be located in such a way that the air flowing through the matrix has free flow on entry and exit. -
Page 9: Hydraulic Connection
4.3 Hydraulic connection Carry out the hydraulic connection as described in the attached data. Connect the lines stress and vibration free, so typically us- ing hoses. Be sure to use suitable lines (with regard to pressure, fluid resistance, environmental influences, fire) when connecting to the hydraulic-, lubrication circuit. -
Page 10: Electrical Connection Temperature Switch Tsa (Accessory)
4.4.1 Electrical connection temperature switch TSA (accessory) The temperature switch TSA is installed in a cooling circuit with an oil/air cooler ELK as a typical application. Through reaching the switching temperature the fan-motor is switched-on and the oil will be cooled. After falling under the hysteresis the motor shuts off. -

Page 13: Cleaning And Disassembly Of The Cooler Matrix
6.1 Cleaning and disassembly of the cooler matrix Due to the design of the cooling fins, the cooler has low susceptibility to dust and dirt. Normally, it is sufficient to clean the front surface with a brush. However, particularly if the air has a high dust and/or oil mist content, the cooling matrices may require regular cleaning. -
