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: General Safety Instructions
1| Safety 1.3 General safety instructions WARNING Risk of accidents. Refrigerating compressors are pressurised machines and as such call for heightened caution and care in handling. The maximum permissible overpressure must not be exceeded, even for testing purposes. Risk of burns! - Depending on the operating conditions, surface temperatures of over 60°C on the discharge side or below 0°C on the suction side can be reached. -

Page 10: Compressor Assembly
4| Compressor assembly INFO New compressors are factory-filled with inert gas. Leave this ser- vice 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. -
Page 11: 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. -

5| Electrical connection DANGER Risk of electric shock! High voltage! Only carry out work when the electrical system is disconnected from the power supply! ATTENTION When attaching accessories with an electrical cable, a minimum bending radius of 3 x the cable diameter must be maintained for laying the cable. - Page 14 5.3 Circuit diagramm for direct start 230 V ∆ / 400 V Y FC1.1 I> I> I> FC1.1 L3 N PE -EC1 Θ B1 B2 INT69G Compressor terminal box Anschlußkasten Verdichter Fig. 13 Cold conductor (PTC sensor) motor winding Thermal protection thermostat (PTC sensor) Load circuit safety switches Control power circuit fuse High pressure safety monitor Safety chain (high/low pressure monitoring ) Main switch...

Reset after mains on 11-14 5.7 Start unloader To avoid current peaks during the starting phase we recommend using the GEA Bock-ESS soft starting device (Electronic Soft Start). Refer to "Accessories" for further information. 5.8 Fan motor The fan motor for cooling the compressor is already wired in the terminal box. The power supply as well as triggering of the compressor contactor should be made in accordance with the basic circuit diagram (in the terminal box). The fan motor is protected by an internal temperature monitor. -
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: Start-Up
6| Commissioning 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. ATTENTION Avoid overfilling the system with refrigerant! To avoid shifts in concentration, zeotropic refrigerant blends (e.g. R407C) must always only be filled into the refrigerating plant in liquid form. -
