4 | Compressor assembly 4.3 V-belt drive ATTENTION Inappropriately designed belt drives, especially belt knocking (offsets, inclinations) 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: 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 14: 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 15: Avoiding Liquid Shocks
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. -
