Page 5: Intended Use
1| Safety 1.4 Intended use These assembly instructions describe the standard version of the HG22e manufactured by Bock. The compressor is intended for use in refrigeration systems in compliance with the limits of application. Only the refrigerant specified in these instructions may be used. Any other use of the compressor is prohibited! WARNING! The compressor may not be used in potentially explosive environments! The Bock refrigerating compressor named in the title is intended for installing in a machine (within the EU according to the EU Directives 2006/42/EC Machinery Directive, 97/23/EC Pressure Equipment Directive and 2006/95/EC – Low Voltage Directive). Commissioning is only permissible if the compressor has been installed in accordance with these a ssembly instructions and the entire system into which it is integrated has been inspected and a pproved in accordance with legal regulations. -

Page 10: Compressor Assembly
4| Compressor assembly INFO! New compressors are factory-filled with inert gas (3 bar nitrogen). 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 Setting up Use transport eyelet. Do not lift manually! Use lifting gear! Fig. 9 Provide adequate clearance for maintenance work. -
Page 11: Pipes
4| Compressor assembly 4.3 Pipes Pipes and system components must be clean and dry inside and free of scale, swarf and layers of rust and phosphate. Only use air-tight parts. Lay pipes correctly. Suitable vibration compensators must be provided to prevent pipes being cracked and broken by severe vibrations. Ensure a proper oil return. Keep pressure losses to an absolute minimum. 4.4 Laying suction and pressure lines INFO! Proper layout of the suction and pressure lines directly after the compressor is integral to the smooth running and vibration behaviour of the system. -

Page 16: Start Unloader
5| Electrical connection 5.4 Start unloader To avoid current peaks during the starting phase we recommend using the Bock-ESS soft starting device (Electronic Soft Start). Refer to "Accessories" for further information. 5.5 Electronic trigger unit MP 10 The compressor motor is fitted with cold conductor temperature sensors (PTC) connected to the electronic trigger unit MP 10 in the terminal box. Readiness to operate is signalled by the H3 LED (green) after the power supply is applied. In the case of excess temperature in the motor winding, the unit switches off the compressor and the H1 LED lights red. The hot gas side of the compressor can also be protected against overtemperature using a thermal protection thermostat (accessory). The H2 LED (red) is provided for the protection function. The unit trips when an overload or inadmissible operating conditions occur. Find and remedy the cause. - Page 17 5| Electrical connection 5.7 Function test of the trigger unit MP 10 Before start-up, troubleshooting or making changes to the control power circuit, check the functionality of the trigger unit: LED H1 LED H2 LED H3 Procedure green • Interrupt power supply (L1 or S1) • Release the motor temperature sensor connection (1 or 2) • Release the hot gas temperature sensor (if installed) (3 or 4) • Restore the power supply (L1 or S1) •...

Page 18: Commissioning
6| Commissioning 6.1 Preparations for start-up INFO! In order to protect the compressor against inadmissible operating conditions, high-pressure and low-pressure pressostats controls 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. Check the compressor for transport damage! 6.2 Pressure strength test DANGER! Bursting! The compressor must only be pressurised using nitrogen ). Never pressurise with oxygen or other gases! The maximum permissible overpressure of the compressor must not be exceeded at any time during the testing process (see name plate data)! Do not mix any refrigerant with the nitrogen as this could... -
Page 19: Refrigerant Charge
6| Commissioning 6.5 Refrigerant charge CAUTION! Wear personal protective clothing such as goggles and protective gloves! Make sure that the suction and pressure line shut-off 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. INFO! Avoid overfilling the system with refrigerant! I n order to prevent shifts in concentration, zeotropic refrigerant blends (e.g. R407C) must always only be added to the refrigerating system in liquid form. -

6| Commissioning 6.8 Connection of oil level regulator The connection "O" is provided for installing an oil level regulator. A corresponding adapter must be obtained from the trade. 7| Maintenance 7.1 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. -
