4| Compressor assembly INFO! New compressors are factory-filled with inert gas (3 bar nitrogen). Leave this service 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.

5| Electrical connection 5.9 Oil sump heater (accessories) During compressor standstill and depending on the pressure and ambient temperature, refrigerant diffuses into the compressor's lubricating oil. This reduces the oil's lubricating ability. When the compressor is started, the refrigerant contained in the oil evaporates due to the decline in pressure. This can result in oil foaming and oil exodus which can result in oil hammer in certain circumstances. -
Page 23: Commissioning
6| Commissioning 6.1 Preparations for start-up INFO! In order to protect the compressor against inadmissible operating conditions, high-pressure and low-pressure pressostats controls 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 24 6| Commissioning 6.5 Refrigerant filling CAUTION! Wear personal protective clothing such as goggles and protective gloves! 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.
