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 4.3 Pipe connections ATTENTION! Fig. 14: graduated internal diameter Do not solder as long as the compressor is under pressure. Superheating can damage the valve. Remove the pipe supports therefore from the valve for soldering and accordingly cool the valve body during and after soldering. Only solder using inert gas to inhibit oxidation products (scale).
4| Compressor assembly 4.6 Operating the shut-off valves Before opening or closing the shut-off valve, release the valve spindle seal by approx. ¼ of a turn counter-clockwise. After activating the shut-off valve, re-tighten the adjustable valve spindle seal clockwise. Tighten Release Valve spindle seal Fig. 17 Fig. 16 4.
5| Electrical connection 5 Electrical connection DANGER! High voltage! Risk of electric shock! Only carry out work when the electrical system is disconnected from the power supply! INFO! 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 5.4 Start unloader To avoid current peaks during the starting phase we recommend using the GEA Bock-ESS soft starting device (Electronic Soft Start). Refer to "Accessories" for further information. 5.5 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 signalled by the H3 LED (green) after the power supply is applied.

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.
6| Commissioning 6.5 Refrigerant charge 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.
6| Commissioning 6.8 Connection of oil level regulator The connection "O" is provided for installing an oil level regulator. A corresponding adapter must be obtained from the trade. 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.
