CAUTION! 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:...
1| Safety 1.3 General safety instructions WARNING! • Refrigerating compressors are pressurised machines and t herefore require particular caution and care in handling. • Risk of burns! Depending on the operating conditions, surface temperatures of over 60 °C on the pressure side or below 0 °C on the suction side can be reached. • The maximum permissible overpressure must not be exceeded, even for testing purposes. 1.4 Intended use These assembly instructions describe the standard version of the HA5 manufactured by GEA.

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 4.3 Pipe connections ATTENTION! Superheating can damage the valve. Remove the pipe supports from the valve for soldering. Only solder using inert gas to inhibit oxidation products (scale). 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.
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. Release Tighten Valve spindle seal Fig.
5| Electrical connection 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). Use suitable cable entry point of the correct protection type (see name plate) for routing cables into the terminal box.

5| Electrical connection 5.9 Oil sump heater (accessories) During compressor standstill and depending on the pressure and ambient temperature, refrigerant diffuses into the compressor's lubricating oil. This reduces the oil's lubricating ability. When the compressor is started, the refrigerant contained in the oil evaporates due to the decline in pressure. This can result in oil foaming and oil exodus which can result in oil hammer in certain circumstances.
6| Commissioning 6.1 Preparations for start-up INFO! I n 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 filling 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.
6| Commissioning 6.8 Connection of oil level regulator Oil level regulation systems have proven themselves with parallel circuits of several compressors. The connection "0" is provided for installing an oil level regulator (see dimensions drawing). All common oil level regulators from AC&R, ESK and Carly as well as the OM3 TraxOil oil level regulation system from Alco can be connected directly without adapters (see Fig.
