Page 20: 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. Check the compressor for transport damage! 6.2 Pressure strength test The compressor has been tested in the factory for pressure integrity. -
Page 21: Refrigerant Charge
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. -
Page 22: Maintenance
7 | Maintenance 7.1 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. 7.2 Work to be carried out Oil change: In principle, an oil change is not mandatory if the system is correctly manufactured and operated. -
