10 - 1 Installing and Connecting the High-pressure Pump
（1） Install the manifold block so that it does not interfere with other components in the machine tool.
（2） Install the high-pressure pump, and place the intake filter in the coolant tank of the machine tool.
（3） Install the filter (filtration accuracy of 5 μm or less) and connect it to the high-pressure pump, the
relief valve, and the manifold block with the coolant hose and fittings.
（4） Connect the relief valve to the high-pressure pump or high-pressure pump flow path, and connect
the coolant hose to the discharge side of the relief valve. The coolant hose should be installed so
that the coolant can be discharged into the coolant tank.
