Notes for handling
1. When adverse transport conditions are expected in transporting the machine overseas or elsewhere, special
precautions should be taken in the packaging and transportation method so as to avoid the application of
excessive force on Oil Cooling Unit （this unit）.
2. Oil Cooling Unit （this unit） does not incorporate a flow switch for checking the oil supply and a temperature
switch for abnormal supply of oil temperature （high temperature or low temperature）. So, please provide a
protection device such as a flow switch and a temperature switch on the main machine side.
●Important notes to be observed regarding the main machine side
（machine tools and industrial machine）
Notes for operation and cooling capacity
1. Do not use Oil Cooling Unit for cooling a liquid at 50℃ or more. Start to operate Oil Cooling Unit at the
same time as the main machine or before liquid temperature rises to 40℃.
2. Do not place an object that hinders ventilation within 500mm of the suction port or discharge port.
3. If the air filter is clogged, the cooling capacity is reduced. Clean the air filter （wash with hot water or
clean with air） periodically once every two weeks to prevent clogging.
