Page 11: 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 Setting up Fittings (e.g. pipe holders, additional units etc.) on the compressor are permissible only following consultation with GEA. -
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 t ensioners and selecting the belt profile and the belt length. 4.4 Main bearing load To prevent the belt drive overloading the compressor main bearing, ensure that: The force applied at the force engagement force by the belt... -
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
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 16: 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. -
Page 17: Shaft Seal
5| Commissioning 5.7 Shaft seal ATTENTION Failure to observe the following instructions can cause loss of refrigerant and damage to the shaft seal! INFO The shaft seal seals and lubricates with oil. An oil leakage of 0.05 ml per operating hour is therefore normal. This applies p articularly during the run-in phase (200 - 300 h). -
Page 18: 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. -
Page 19: Recommended Spare Parts
Oil SE 55, 1 Ltr. 02282 Only use genuine GEA spare parts! 6.5 Integrated decompression valve (only FK30/275 + 325) The valve is maintenance free. However, constant leakage can occur after blowing off due to abnormal operating conditions. This leads to reduced performance and increases the compressed gas temperature. In this case check the valve and replace as necessary. -
