Further information on request.
Connect the cooling water to the connectors; see Fig. 37.
The CT versions have a cooling water bypass.
Make sure that you do not mix up the inlet and the outlet con-
nection.
Turn off the cooling water supply when the pump is switched off in order to
avoid condensate formation in the pump.
If you do not close the cooling water it may take longer to achieve ultimate
pressure after start up of the system.
No cooling water is reqired when operating the pump at ultimate pressure.
Cooling water is only reqired when baking out the pump.
