1 | Safety 1.3 General safety instructions DANGER! • Refrigerating compressors are pressurised machines and as such call for heightened caution and care in handling. The maximum permissible overpressure must not be exceeded, even for testing purposes. WARNING! • Risk of burns! Depending on the operating conditions, surface temperatures of over 60°C on the discharge side or below 0°C on the suction side can be reached. 1.

5| 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. 5.1 Setting up WARNING! Move compressors only with hoists that have adequate load-bearing capacity. Transport and suspension unit on the eyebolt (Fig. 12, F14 to F16) or direct on the discharge line valve (Fig. 11, F2 to F5). D GB Fig.

A A a Fig. 16 a A A a a A max. 30°, max. 2 minutes a max. 15°, continuous operation D GB F E 5.3 Pipe connections ATTENTION! Overheating can damage the valve. Remove the pipe supports from the valve for soldering. Only solder using inert gas to inhibit oxidation products (scale). 09702-09.2013-DGbF Fig.
5| Compressor assembly 5.5 Laying suction and discharge lines INFO! Proper layout of the suction and discharge lines directly after the compressor is integral to the system’s smooth running and vibration behaviour. ATTENTION! Improperly installed pipes can cause cracks and tears, the result being a loss of refrigerant. A rule of thumb: Always lay the first pipe section starting from the shut-off valve downwards and parallel to the drive shaft.
5| Compressor assembly 5.7 Operating mode of the lockable service connections Service connection closed Spindle Connection blocked Pipe connection Opening the shut-off valve: Spindle: turn to the left (counter-clockwise) as far as it will go. —> The shut-off valve is then fully open and the service connection is closed. The connection which is not lockable is provided for safety devices. Fig. 21 Service connection opened D GB F Spindle Connection open E Pipe connection Fig. 22 09702-09.
5| Compressor assembly 5.8 Drive ATTENTION! Faulty alignment results in premature failure of the coupling and bearing damage! CAUTION! Mount suitable safeguards when driving the compressor by means of V-belts or shaft couplings! The compressors of the F series can be driven by V-belts or directly by shaft couplings. V-belt: Proper assembly of belt drive: - The pulleys of compressor and drive motor must be firmly mounted and in line. - Only use V-belts with calibrated lengths.
5| Compressor assembly 5.9 Oil sump heating When the compressor is at a standstill, refrigerant diffuses into the lubrication oil of the compressor housing, depending on pressure and ambient temperature. This reduces the lubrication capacity of the oil. When the compressor starts up, the refrigerant contained in the oil evaporates out through the reduction in pressure. The consepuences can be lack of lubrication, foaming and migration of the oil, which can eventually lead to compressor damage.
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.
6| Commissioning 6.7 Shaft seal change As changing the shaft seal involves opening the refrigerant circuit, this is recommended only if the seal is losing refrigerant. Replacing the shaft seal is described in the spare part kit concerned. 6.8 Start-up WARNING! Ensure that both shut-off valves are open before starting the compressor! Check that the safety and protection devices (pressure switch, motor protection, electrical contact protection measures, etc.) are all functioning properly.
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.
