  • Page 5: General Safety Instructions

    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.

  • Page 12: Compressor Assembly

    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| Compressor assembly 5.2 Maximum permissible inclination ATTENTION! Poor lubrication can damage the compressor. Respect the stated values. max. 30°, max. 2 minutes max. 15°, continuous operation Fig. 16 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).

  • Page 14: Laying Suction And Discharge Lines

    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.

    5| Compressor assembly 5.7 Operating mode of the lockable service connections Service connection closed Connection Pipe connection Spindle blocked Fig. 21 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.

  • Page 16: Drive

    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.

  • Page 17: Oil Sump Heating (Standard By F4, F5, F14 And F16)

    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.

  • Page 18: Preparations For Start-Up

    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.

  • Page 19: Refrigerant Charge

    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.

  • Page 20: Shaft Seal Change

    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...

  • Page 21: Maintenance

    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.
