NOTICE
Inlet temperature of the cooling water
If the minimum inlet temperature of the cooling water cannot be maintained or reached, this
may result in condensation forming on the machine.
Adopt appropriate measures to achieve the inlet temperature of the cooling water.
Alternatively, you can dry the ambient air.
6.1.2

Connecting the cooling water supply

The inlet and outlet sockets for the cooling water supply are situated on the non-drive end in
the bearing shield. On the bearing shield, two hexagonal couplers with female thread are
each screwed on a washer: At shaft heights of 180 and 225, hexagonal couplers with
female thread are used, at a shaft height of 280
1. Use only valves, fittings and cooling water pipes made of non-corrosive, high-grade steel
2. Make sure that the cooling water meets the required cooling water specification, see
3. Make sure that the appropriate volume of cooling water is available, see rating plate
4. Hold the hexagon head steady with an open-ended spanner while you screw in the water
5. Screw the cooling water pipes into the female thread. You can connect the inlet and
6. Make sure that the maximum permissible operating pressure does not exceed 6 bar.

NOTICE
Securing the hexagonal couplers
The hexagonal couples are directly connected to the water pipes inside the machine.
The use of excessive torque on screwing in can damage the pipe system.
Hold the couplers steady with an open-ended spanner when you screw in the water
pipes.
The pressure drop is determined by the machine type and the shaft height:
