Safety Prior to handling the machine, this instruction manual should be read and understood. If anything needs to be clarified, please contact your Busch representative. Read this manual carefully before use and keep for future reference. This instruction manual remains valid as long as the customer does not change anything on the product.
Conveying of other media leads to an increased thermal and/or mechanical load on the machine and is permissible only after a consultation with Busch. The machine is intended for the placement in a non-potentially explosive environment. The machine is capable of maintaining ultimate pressure, see Technical Data [► 34].
Product Description | 2 The machine must be stopped when the temperature switch trips (100 °C). 2.3.3 Thermometer The thermometer allows a visual display of the cooling liquid temperature. 2.3.4 Sealing Systems The machine is equipped with labyrinth seals on the motor side and suction side. Other sealing systems are optionally available, see Mechanical Seals [► 7].
3 | Transport The following devices are available: – The barrier gas system for sealing systems on motor side. This device is equipped with a flow switch integrated to the flow meter to switch off the machine if the ni- trogen volume flow drops below the minimum set flow value.
Storage | 4 WARNING Lifting the machine using the motor eye bolt. Risk of severe injury! • Do not lift the machine using the eye bolt fitted to the motor. Only lift the machine as previously shown. • Check the machine for transport damage. If the machine is secured to a base plate: •...
