CAUTION Contact with POE! Material damage! POE lubricant must be handled carefully and the proper protective equipment (gloves, eye protection, etc.) must be used at all times. POE must not come into contact with any surface or material that might be harmed by POE, including without limitation, certain polymers, eg,.
Product description Common information about Copeland Stream™ semi-hermetic compressors These guidelines cover Copeland Stream™ semi-hermetic compressors. The semi-hermetic reciprocating compressor family consists of different ranges. The Stream™ series of 4M* and 6M* models ranges from 13 hp to 50 hp. High temperature Medium temperature Low temperature...
Nameplate information All important information for identification of the compressor is printed on the nameplate located below the compressor oil pump. The type of refrigerant used should be stamped on the nameplate by the installer. Figure 1 The year and month of production are shown as part of the serial number (Jan = A, Feb = B, … Dec = L).
2.5.2 Application limits For application envelopes please refer to Copeland brand products Select software at www.emersonclimate.eu. Design features 2.6.1 Compressor construction All compressors are fitted with Stream valve plates which cannot be dismantled. To maintain the high capacity of these compressors in case of exchange, the correct valve-plate-to-body gasket must always be selected.
2.6.6 Oil pumps The oil pumps used for Stream compressors are independent of their rotating direction. On compressors delivered with CoreSense™ Diagnostics (-D), the oil pump integrates the electronic switch for integrating oil pressure safety functionality. Compressors with CoreSense™ Protection (-P) are designed to accommodate fittings for an OPS2, FD-113ZU, or Sentronic oil safety system or a standard oil pressure switch (OPS2 oil sensor included in the oil pump).
Installation WARNING High pressure! Injury to skin and eyes possible! Be careful when opening connections on a pressurized item. Compressor handling 3.1.1 Delivery Please check whether the delivery is correct and complete. Any deficiency should be reported immediately in writing. Standard delivery: ...
In order to avoid refrigerant leaks or other damage the compressors should not be lifted by the service valves or other accessories. 3.1.4 Installation location Ensure the compressors are installed on a solid level base. 3.1.5 Mounting parts To minimize vibration and start/stop impulses flexible mounting should be used. For this purpose one set of spring mounting parts for each of the Stream models is delivered with each 4M* and 6M* compressor.
NOTE: The compressor operating range may be restricted for various reasons. Check the application range limitations in Copeland brand products Select software at www.emersonclimate.eu. Brazing procedure IMPORTANT Blockage! Compressor breakdown! Maintain a flow of oxygen-free nitrogen through the system at very low pressure during brazing. Nitrogen displaces the air and prevents the formation of copper oxides in the system.
Electrical connection General recommendations The compressor terminal box has a wiring diagram on the inside of its cover. Before connecting the compressor, ensure that the supply voltage, the phases and the frequency match the nameplate data. The knockouts have to be removed before the electrical glands can be installed. First make sure that the terminal box is closed with the terminal box cover.
4.3.1 Wiring diagram for part-winding motors (AW…) Part winding motors can be connected direct-on-line or part-winding start. NOTE: The sensor module inside the terminal box requires a separate 24V AC power supply. Part-winding start Direct-on-line start First start step 1–2-3 Y - Y Y - Y Part-winding motor:...

Protection devices Independently from the internal motor protection, fuses must be installed before compressor start-up. The selection of fuses has to be carried out according to VDE 0635, DIN 57635, IEC 269-1 or EN 60-269-1. CoreSense™ Diagnostics CoreSense™ Diagnostics is used for all 4M* and 6M* Stream semi-hermetic compressors. It combines oil and motor protection in one module, replacing OPS1/2 and the electronic module INT69TM.
For the electrical connection of the CoreSense Diagnostics module, refer to the wiring diagram below: Figure 14: CoreSense module wiring diagram NOTE: For more information please refer to Technical Information D7.8.4 "CoreSense™ Diagnostics for Stream refrigeration compressors". CoreSense™ Protection 4.6.1 Motor protection Stream compressors with "-P"...
4.6.2 Oil pressure control The oil pressure switch breaks the control circuit when the pressure difference between the oil pump outlet and the crankcase is too low. The switch must be properly adjusted and tamper- proof. If the oil differential pressure drops below the minimum acceptable value the compressor will be stopped after a 120-second delay.
Mechanical oil pressure switch – ALCO FD-113ZU (A22 - 057) 4.6.2.2 Specifications for electro-mechanical oil pressure switches are as follows: Cut-out pressure: 0.63 ± 0.14 bar Cut-in pressure: 0.9 ± 0.1 bar Time delay: 120 ± 15 sec. The Alco Control FD-113ZU mechanical oil pressure switch operates with the above set points.
Starting up & operation WARNING Diesel effect! Compressor destruction! The mixture of air and oil at high temperature can lead to an explosion. Avoid operating with air. Leak test The suction shut-off valve and discharge shut-off valve on the compressor must remain closed during pressure testing to prevent air and moisture from entering the compressor.
MUST NOT be started, nor may high-potential testing be carried out under vacuum. Minimum run time Emerson Climate Technologies recommends a maximum of 10 starts per hour. The most critical consideration is the minimum run time required to return oil to the compressor after start-up.
Compressors supplied by Emerson Climate Technologies contain oil with low moisture content, and it may rise during the system assembling process. Therefore it is recommended that a properly sized filter-drier is installed in all POE systems.
Oil additives Although Emerson Climate Technologies cannot comment on any specific product, from our own testing and past experience, we do not recommend the use of any additive to reduce compressor bearing losses or for any other purpose. Furthermore, the long-term chemical...
