2 2/24 osch Rexroth G Hydraulics KOL; KOLP RE 50111/12.06 Description Oil/air coolers are used to dissipate heat. Due to pressure drops in lines and components, energy is released in the hydraulic system in the form of heat. This heat is dissipated into the atmosphere with the help of oil/air coolers. This ensures that the hydraulic fluid temperature can be kept within the optimum temperature range for the hydraulic components. These oil/air coolers basically consist of an electric motor, housing, cooler element and fan wheel. In the version with radial fan wheel, the oil/air cooler is also available as complete ymbols ymbol for oil/air cooler (Types KOL.../... and KOL.../R...) circulation circuit (built-on external gear pump with or without filter). The units can be installed vertically or horizontally. For horizontal mounting of the oil/air coolers, four oblong holes are provided on the mounting strips. For mounting in the vertical position, the oblong holes for mounting are provided on the cooler element. ee also Unit dimensions. Filters are optionally available with electrical or visual clogging indicator. When operating the oil/air cooler in a heavily soiled environment, we recommend the use of an oil/air cooler with air filter mat. ymbol for oil/air cooler with pump (Type KOLP.../R...)

23 RE 50111/12.06 KOL; KOLP Hydraulics osch Rexroth G 23/24 Installation notes Check that the oil/air cooler has been properly connected (hydraulically and electrically) to the machine to be operated. For the electrical connections of the electric motor, use the washers and connecting bridges that are included in the scope of supply. Check the direction of rotation of the fan wheel (anti-clockwise) by briefly switching on the electric motor (see also direction of rotation arrow on the housing). The electric motor must be protected by a feature incorporating an overload relay. This must be set to the nominal current indicated on the nameplate / performance plate. When installing the oil/air cooler with external gear pump (type KOLP.../R... and KOLP.../R-...F...), take particular care of the motor s direction of rotation, see direction of rotation arrow. In no case may the pump of the oil/air cooler (type KOLP.../ R... and KOLP.../R-...F...) be run without hydraulic fluid. oreover, ensure sufficient lubrication of the pump. To achieve the optimum cooling capacity, the oil/air cooler must be bled before commissioning. In addition, care should be taken that the units operate bubble-free. The oil/air cooler may only be used within the permissible data limits. oreover, it may only be operated when it is in a flawless condition. When carrying out any work on the oil/air cooler, depressurise the system and disconnect it from the power supply. In addition, see to it that the fan wheel does no longer rotate. Unauthorised conversions or changes that affect safety and functions are not permitted. Never remove any existing protective features or guards. Keep the oil/air cooler clean and do not cover it; change clogged filter mats, because otherwise the hydraulic fluid will overheat. trictly observe general safety and accident prevention regulations. Note relating to EC achinery Directive 98/37/EC, nnex II, ection : The assemblies are manufactured to comply with the harmonised standards EN 982, EN 983, DIN EN IO and DIN EN Commissioning is prohibited until it was established that the machine, into which the assembly is to be integrated, conforms with the stipulations of the EC Directive. ttention! The oil/air cooler can heat up during operation risk of injury! Only authorised, trained and instructed personnel are allowed to make settings and carry out maintenance and servicing on the oil/air cooler. Use only genuine osch Rexroth spare parts for repairs! Caution! If osch Rexroth hydraulic products are installed in the vicinity of sources of ignition or strong heat radiators, a shield must be provided in order that the hydraulic fluid cannot ignite in the case of spillage and hoses are protected against premature aging. Hydraulic oil based on mineral oil is water-endangering and inflammable. It may only be used, if the corresponding safety data sheet of the manufacturer is available and all precautions described therein were taken. If leakage of the hydraulic product can lead to water or ground contamination, the hydraulic product must be placed in a suitable collection tank. In Germany, hydraulic systems are classified as systems for handling water-endangering substances in the sense of the Water Resources ct (WHG). In this context, please observe in particular 1 and 19 WHG ( 19g, 19i, 19l).
