1. With the "Piping" option, piping is attached on the right, left or top at the NDE. You can then
connect the coolant supply radially to the appropriate side.
Different threads are available depending on the machine type.

2. Use flexible water lines and hoses. This avoids mechanical stress at the connections as a
result of the heat-dependent height increase of the machine (thermal expansion).
3. Only use valves, fittings and cooling water pipes made of rust-proof, stainless steel in the
cooling system.
4. Make sure that the cooling water complies with the required cooling water specification.
5. Make sure that the appropriate volume of cooling water is available.
6. Hold the hexagon coupler with an open-ended wrench while you screw in the water pipes.
NOTICE
Damage to the pipe system
The hexagonal couplers are connected directly to the water pipes inside the machine.
Applying excessive torque when screwing in can damage the pipe system.
● Hold the couplers with an open-ended wrench while you screw in the water pipes.
● Avoid axial forces at the coolant connections.
7. Screw the cooling water pipes into the female thread. You can connect the inlet and outlet
as required.

NOTICE
Bleed air from the cooling ducts
Adequate machine cooling cannot be guaranteed if the cooling ducts are not completely filled
with water. The machine can overheat.
● Vent the cooling ducts when filling. Completely fill the cooling ducts with water.
