Note
Observe the flow direction of the pump
When connecting the valves, observe the flow direction of the pump.
Refer to the pump operating instructions in the complete gear unit documentation to ascertain
whether the flow direction of the pump used depends on the direction of rotation.
Improper use can damage the gear unit. Follow the instructions given below in order to protect
the gear unit against overheating:
● When installing a gear unit with mounted air-oil cooler, carefully ensure that air can freely
circulate.
The necessary minimum clearance to adjacent components such as walls and panels is
specified in the dimension drawing in the complete gear unit documentation.
● Please note that the cooling effect is considerably reduced as a result of a dirty air-oil cooler
or the insulating effect of dirt or pollution on the housing surface.
Clean the air-oil cooler and the gear unit. Cleaning information is provided in
chapter Cleaning the fan and gear unit (Page 93).
Further information
Additional information such as connection dimensions and a detailed illustrated description of
the gear unit and the oil supply system with air-oil cooler can be found in the dimension drawing
in the complete gear unit documentation.
Additional information about the oil supply system and control notes can be found in the
separate data sheet, in the list of equipment and in the oil supply system operating instructions
provided in the complete gear unit documentation.
Temperature control valve
A temperature control valve is installed in the air-oil cooler bypass.
Principle of operation
At a preset temperature, the temperature control valve starts to open and some oil flows
through the oil cooler; when a second preset temperature is reached, then all of the oil flows
through the oil cooler.
Further information
You can find additional information on the temperature control valve in the temperature control
valve operating instructions provided in the complete gear unit documentation.
You can find additional technical data in the separate data sheet and in the list of equipment
provided in the complete gear unit documentation.
