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 Fig. 9 ? 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 combustible environment. Use transport eyelet.

4 | Compressor assembly 4.5 Pipes Pipes and system components must be clean and dry inside and free of scale, swarf and layers of rust and phosphate. Only use air-tight parts. Lay pipes correctly. Suitable vibration compensators must be provided to prevent pipes being cracked and broken by severe vibrations. Ensure a proper oil return. Keep pressure losses to an absolute minimum. 4.

After activating the shut-off valve, re-tighten the adjustable valve spindle seal clockwise. Release Tighten Valve spindle seal Fig. 18 Fig. 17 4.
5| Electrical connection 5 Electrical connection DANGER! INFO! High voltage! Risk of electric shock! Only carry out work when the electrical system is disconnected from the power supply! onnect the compressor motor in accordance with the circuit diagram C (see inside of terminal box). Use suitable cable entry point of the correct protection type (see name plate) for routing cables into the terminal box. Insert the strain reliefs and prevent chafe marks on the cables.
5| Electrical connection The compressor is designed with a motor for star-delta circuits. Designation on the name plate Sticker on the terminal box Niedere Spannung Low voltage Bas voltage ∆ ∆/Y Star-delta start-up is only possible in the ∆ voltage range.

5| Electrical connection 5.4 Electronic trigger unit MP 10 The compressor motor is fitted with cold conductor temperature sensors (PTC) connected to the electronic trigger unit MP 10 in the terminal box. Readiness to operate is signaled by the H3 LED (green) after the power supply is applied. In case of excess temperature in the motor winding, the unit switches off the compressor and the H1 LED illuminates red.

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 DANGER! Bursting! The compressor must only be pressurised using nitrogen (N2).
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.
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.
