Page 5: General Safety Instructions
Only the refrigerant specified in these instructions may be used. Any other use of the compressor is prohibited! The GEA refrigerating compressor named in the title is intended for installation in a machine (within the EU according to the EU Directives 2006/42/EC Machinery Directive, 97/23/EC Pressure Equipment Directive). -

Page 11: Compressor Assembly
WARNING! Move compressors only with hoists that have adequate load-bearing capacity. Transport and suspension unit on both eyebolts (Fig. 8). Fig. 8 Fittings (e.g. pipe holders, additional units etc.) on the compressor are permissible only following consultation with GEA. 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. 4.2 Maximum permissible inclination ATTENTION! Poor lubrication can damage the compressor. -
Page 12: 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 tensioners 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 13: Pipe Connections
4| Compressor assembly 4.6 Pipe connections The discharge and suction line valves have stepped internal diameters, enabling the use of pipes with standard millimetre and inch dimensions. The depth of pipe insertion will depend on the dimension. The connection diameters of the shut-off valves are designed for maximum compressor output. -

Page 15: Commissioning Cn
5| Commissioning 5.1 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 16: Refrigerant Charge
5| Commissioning 5.5 Refrigerant charge CAUTION! Wear personal protective clothing such as goggles and protective gloves! ATTENTION! Avoid overfilling the system with refrigerant! To avoid shifts in concentration, zeotropic refrigerant blends (e.g. R407C) must always be added to the refrigerating plant in liquid form. Do not pour liquid refrigerant through the suction line valve on the compressor. -
Page 17: Shaft Seal, Emptying The Oil Reservoir
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. -

Capacity-regulated operation alters the gas speeds and pressure r atios 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... -
