1| Safety 1.1 Identification of safety instructions: Indicates a dangerous situation which, if not DANGER! avoided, will cause immediate fatal or serious injury. Indicates a dangerous situation which, if not WARNING! avoided, may cause fatal or serious injury. Indicates a dangerous situation which, if not CAUTION! avoided, may cause fairly severe or minor injury. Indicates a situation which, if not ATTENTION! avoided, may cause property damage. INFO! Important information or tips on simplifying work. 1.2 Qualifications required of personnel WARNING! I nadequately qualified personnel poses the risk of accidents, the consequence being serious or fatal injury. Work on compressors must therefore only be performed by personnel with the qualifica- tions listed below: •...
Any other use of the compressor is prohibited! WARNING! The compressor may not be used in potentially explosive environments! The GEA refrigerating compressor named in the title is intended for installing in a machine (within the EU according to the EU Directives 2006/42/EC Machinery Directive, 97/23/EC Pressure Equipment Directive and 2006/95/EC – Low Voltage Directive).

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.
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. Fig.

After activating the shut-off valve, re-tighten the adjustable valve spindle seal clockwise. Release Tighten Valve spindle seal Fig.

Electrical connection DANGER! H igh voltage! Risk of electric shock! Only carry out work when the electrical system is disconnected from the power supply! ATTENTION! When attaching accessories with an electrical cable, a minimum bending radius of 3 x the cable diameter must be maintained for laying the cable. INFO! Connect the compressor motor in accordance with the circuit diagram (see inside of terminal box).

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.
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. 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.
