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: Safety Instructions
Only the refrigerant specified in these instructions may be used. Any other use of the compressor is prohibited! The Bock refrigerating compressor named in the title is intended for installation in a machine (with- in 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 Brief description Three different designs are available for various ranges of application: > for air-conditioning the K Design > for air-conditioning or normal cooling the N Design > for deep freezing the TK Design The differences lie mainly in the valve plate tooling which is adapted to each application range where operational safety and efficiency are concerned. -

HP: Max. -
Page 8: Areas Of Application
Chapter 6.6. 3.3 Limits of application ATTENTION Compressor operation is possible within the operating limits. These can be found in Bock compressor selection tool (VAP) under vap.bock.de. Observe the information given there. - Max. permissible discharge end temperature: 140°C - Permissible ambient temperature: (-20°C) - (+100°C) -
Page 9: Compressor Assembly
Storage at (-40°C) - (+100°C), maximum permissible relative humidity 10% - 95%, no condensation. Fittings (e.g. pipe holders, additional units etc.) on the compressor are permissible only following consultation with Bock. Setup on an even surface or frame with sufficient load-bearing capacity. Use all 4 fastening points. Correct setup of the compressor and mounting of the belt drive are decisive for running comfort, operating safety and the service life of the compressor. -
Page 10: V-Belt Drive
4| Compressor assembly 4.3 V-belt drive ATTENTION Inappropriately designed belt drives, especially belt knocking or excessive tensioning forces can cause compressor damage! Make sure that the drive belt is designed correctly, e.g. by using t ensioners and selecting the belt profile and the belt length. During operation with capacity controllers (Accessories, Chap. 7), the changing load can cause increased running noises and belt drive vibrations. -
Page 11: Pipe Connections
4| Compressor assembly 4.6 Pipe connections The pipe connections have stepped internal diameters so that pipes with standard millimetre and inch dimensions can be used. The connection diameters of the shut-off valves are designed for maximum compressor output. The required pipe cross-section must be matched to the capacity. -

Page 14: Preparations For Start-Up
5| Commissioning 5.1 Preparations for start-up INFO To protect the compressor against inadmissible operating condi- tions, 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 15: Refrigerant Charge
5| Commissioning 5.5 Refrigerant charge CAUTION Wear personal protective clothing such as goggles and protective gloves! Make sure that the suction and discharge line valves are open. With the compressor switched off, add the liquid refrigerant directly to the condenser or receiver, breaking the vacuum. If the refrigerant needs topping up after starting the compressor, it can be topped up in vapour form on the suction side, or, taking suitable precautions, also in liquid form at the inlet to the evaporator. -
Page 16: Avoiding Liquid Shocks
5| Commissioning The compressor shaft is sealed to outside using a shaft seal. The sealing element rotates with the shaft. The following is especially important to ensuring fault-free operation: The complete refrigerant circuit must be correctly executed and clean inside. Heavy shocks and vibrations to the shaft as well as continuous cyclic operation are to be avoided. -
Page 17: Maintenance
6| Maintenance 6.1 Preparation WARNING Before starting any work on the compressor: Switch off the compressor and secure it to prevent a restart. Relieve compressor of system pressure. Prevent air from infiltrating the system! After maintenance has been performed: Connect safety switch. Evacuate compressor. Release switch lock. 6.2 Work to be carried out Oil change: In principle, an oil change is not mandatory if the system is correctly manufactured and operated. -

7| Accessories 7.1 Capacity regulation ATTENTION Capacity-regulated operation alters the gas speeds and pressure ratios of the refrigerating plant: Adjust the suction line routing and dimensioning accordingly, do not set the control intervals too close and do not let the system switch more than 12 times per hour (refriger- ating plant must have reached a state of equilibrium). Continuous operation in the control stage is not recommended as the gas velocity in the plant system under certain circumstances does not... -
