Water Connection (Optional) [► 13]. If the machine is installed at an altitude greater than 1000 meters above sea level: • Contact your Busch representative, the motor should be derated or the ambient temperature limited. Make sure that the monitoring devices are correctly connected and integrated into a control system such that operation of the machine will be inhibited if the safety limit val- ues are exceeded, see Electrical Connection of the Monitoring Devices [► 19]. -
Page 13: Discharge Connection
Depending on the specific order, other connection dimensions may apply. If the machine is used as part of a vacuum system: • Busch recommends the installation of an isolation valve in order to prevent the oil from flowing back to the vacuum system. - Page 14 5 | Installation The thermostatic valve (TV) is used to control the water flow in order to keep a stable machine temperature. The factory default adjustment of the thermostatic valve (TV) is set in position 2 (approx. 75°C oil temperature). The pressure switch (PS) is used to monitor the presence of water at the cooling system of the machine.
