1| Safety 1.3 General safety instructions WARNING Risk of accidents. 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. 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. -

4| Compressor assembly INFO New compressors are factory-filled with inert gas. Leave this ser- vice 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 humi- dity 10 % - 95 %, no condensation Do not store in a corrosive, dusty, vaporous atmosphere or in a com- bustible environment. Fig. 7 Use transport eyelet. -
Page 11: Pipes
4| Compressor assembly The pipe connections have graduated inside diameters so that pipes with standart millimetre and inch dimensions can be used. T he 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. 12: graduated internal diameter 4.4 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. -

Page 16: Electronic Trigger Unit Mp10
5| Electrical connection 5.4 Electronic trigger unit MP10 The compressor motor is fitted with cold conductor temperature sensors (PTC) connected to the elec- tronic trigger unit MP10 in the terminal box. Readiness to operate is signalled by the H3 LED (green) after the power supply is applied. In the case of excess temperature in the motor winding, the unit switches off the compressor and the H1 LED lights red. The hot gas side of the compressor can also be protected against overtemperature using a thermal protection thermostat (accessory). The H2 LED (red) is provided for the protection function. The unit trips when an overload or inadmissible operating conditions occur. Find and remedy the cause. INFO The unit has a restart prevention device. After you have rectified the fault, interrupt the mains voltage. This unlocks the restart prevention device and the LEDs H1 and H2 go out. - Page 17 5| Electrical connection 5.6 Function test of the trigger unit MP10 Before start-up, troubleshooting or making changes to the control power circuit, check the functionality of the trigger unit: LED H1 LED H2 LED H3 Procedure green • Interrupt power supply (L1 or SF1) • Release the motor temperature sensor connection (1 or 2) • Release the hot gas temperature sensor (if installed) (3 or 4) • Restore the power supply (L1 or SF1) •...

5| Electrical connection 5.8 Electronic trigger unit INT69 G The compressor motor is fitted with cold conductor temperature sensors (PTC) connected to the electronic trigger unit INT69 G in the terminal box. In case of excess temperature in the motor winding, the INT69 G deactivates the motor contactor. Once cooled, it can be restarted only if the electronic lock of the output relay (terminals B1+B2) is released by interrupting the supply voltage. -

Page 22: Commissioning Ru
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 The compressor has been tested in the factory for pressure integrity. If however the entire system is to be subjected to a pressure integrity test, this should be carried out in accordance with EN 378-2 or a corresponding safety standard without the inclusion of the compressor. -
Page 23: 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 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. ATTENTION Avoid overfilling the system with refrigerant! To avoid shifts in concentration, zeotropic refrigerant blends (e.g. R407C) must always only be filled into the refrigerating plant in liquid form. Do not pour liquid coolant through the suction line valve on the compressor. -
