1| Safety 1.1 Identification of safety instructions: DANGER Indicates a dangerous situation which, if not avoided, will cause immediate fatal or serious injury. WARNING Indicates a dangerous situation which, if not avoided, may cause fatal or serious injury. CAUTION Indicates a dangerous situation which, if not avoided, may cause fairly severe or minor injury. -
Page 5: Intended Use
These assembly instructions describe the standard version of the compressor named in the title manufactured by Bock. Bock refrigerating compressors are intended for installation in a machine (within the EU according to the EU Directives 2006/42/EC Machinery Directive, 2014/68/EU Pressure Equipment Directive). -
Page 6: Product Description
2| Product description 2.1 Short description • Semi-hermetic two-cylinder reciprocating compressor with suction gas cooled drive motor. • The flow of refrigerant sucked in from the evaporator is led over the engine and provides for a particularly intensive cooling. Thus the engine can be kept special during high load on a relatively low temperature level. -

4| Compressor assembly INFO New compressors are factory-filled with inert gas. Leave this service charge in the compressor for as long as possible and prevent the ingress of air. Check the compressor for transport damage before starting any work. 4.1 Storage and transportation Storage at (-30°C) - (+70°C), maximum permissible relative humidity 10% -95 %, no condensation. -
Page 10: Pipes
4| Compressor assembly The pipe connections have graduated inside diameters so that pipes with standart millimetre and inch dimensions can be used. The connection diameters of the shut-off valves are rated for maximum compressor output. The actual required pipe cross section must be matched to the output. The same applies for non-return valves. Fig. -

Page 18: Commissioning
6| Commissioning 6.1 Preparations for start-up INFO To protect the compressor against inadmissible operating conditions, high pressure and low pressure pressostats are mandatory on the installation side. The compressor has undergone trials in the factory and all functions have been tested. There are therefore no special running-in instructions. -
Page 19: Evacuation
6| Commissioning 6.4 Evacuation ATTENTION Do not start the compressor if it is under vacuum. Do not apply any voltage - even for test purposes (must only be operated with refrigerant). Under vacuum, the spark-over and creepage current distances of the terminal board connection bolts shorten;... -
Page 20: Start-Up
6| Commissioning 6.6 Start-up WARNING Ensure that both shut-off valves are open before starting the compressor! Check that the safety and protection devices (pressure switch, motor protection, electrical contact protection measures, etc.) are functioning properly. Switch on the compressor and let it run for at least 10 minutes. The machine should reach a state of equilibrium. -

6| Commissioning 6.8 Avoid slugging ATTENTION Slugging can result in damage to the compressor and cause refrigerant to leak. To prevent slugging: The complete refrigeration system must be properly designed. All components must be compatibly rated with each other with regard to output (particularly the evaporator and expansion valves). -

Available spare parts and accessories can be found on our compressor selection tool under vap.bock.de as well as at bockshop.bock.de. Only use genuine Bock spare parts! 7.4 Lubricants For operation with CO the Bock oil C 85 E is necessary! -
Page 23: Decommissioning
7| Maintenance 7.5 Decommissioning Close the shut-off valves on the compressor. CO does not need to be recycled and can therefore be blown off into the environment. It is essential to ensure good ventilation or conduct the CO into the outdoors to avoid danger of suffocation. When releasing CO , avoid a fast drop in pressure to prevent oil from exiting with it. -
