1| Safety 1.1 Identification of safety instructions: Indicates a dangerous situation which, if not DANGER! avoided, will cause immediate fatal or serious injury. Indicates a dangerous situation which, if not avoided, may cause fatal or serious injury. WARNING! Indicates a dangerous situation which, if not avoided, may cause fairly severe or minor injury.
WARNING! The compressor may not be used in potentially explosive environments! The GEA 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).

- Use a thermal protection thermostat. - Do not operate an additional capacity controller. - O il return at low frequency must be guaranteed. - Consultation with GEA Bock. For operation with capacity regulator: - The suction gas superheat temperature may need to be reduced or set individuallywhen operating near to the threshold When operating in the vacuum range, there is a danger of air en- tering on the suction side.

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 Storage and transport Storage at (-30°C) - (+70°C), maximum permissible relative humidity 10% - 95%, no condensation Do not store in a corrosive, dusty, vaporous atmosphere or in a com- bustible environment.
4| Compressor assembly 4.3 Maximum permissible inclination ATTENTION! Poor lubrication can damage the compressor. Respect the stated values. max. 30°, max. 2 minutes max. 15°, continuous operation Fig. 14 4.4 Pipe connections The discharge and suction line valves have stepped internal diameters so that pipes with standard millimetre and inch dimensions can be used.
4| Compressor assembly 4.5 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.
4| Compressor assembly 4.7 Operating the shut-off valves Before opening or closing the shut-off valve, release the adjustable valve spindle seal by approx. ¼ of a turn counter-clockwise. After activating the shut-off valve, re-tighten the adjustable valve spindle seal clockwise. Release Valve spindle seal Tighten...
5| Electrical connection Electrical connection DANGER! High voltage! Risk of electric shock! Only carry out work when the electrical system is disconnected from the power supply! INFO! Connect the compressor motor in accordance with the circuit diagram (see inside of terminal box). Use suitable cable entry point of the correct protection type (see name plate) for routing cables into the terminal box.

5| Electrical connection 5.4 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 signaled by the H3 LED (green) after the power supply is applied. In case of excess temperature in the motor winding, the unit switches off the compressor and the H1 LED illuminates red.

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.
6| Commissioning 6.5 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.
