Caution!When you receive a unit from Emerson or an authorized representative, it is very important to check the pressureof each unit. If it is found that packing pressure has disappeared, please contact Emerson or an authorizedrepresentative. Failure to report this may cause subsequent failure reports to be unobstructed.OverviewDamage to the unit caused by the transport process should fall within the category of insurance claims and not be amanufacturing defect. It is also advisable to inspect the rest of the unit for obvious physical damage and inform us orour authorized representative in case any is discovered.ZX Platform Condensing Unit and EMP Rack were designed based onthree factors demanded by industry users:DisclaimerThanks for purchasing Copeland Scroll Large ZX Condensing Unit and EMP Rack from Emerson. Large ZXCondensing Unit and EMP Rack exhibit market-leading quality in terms of cooling capacity and operatingrange, as part of product extension for Next Generation ZX platform in larger capacity range and installationvariants. The product is designed to operate reliably and to deliver high operating efficiencies in medium andlow temperature refrigeration applications. It also provides constant monitoring of the compressor operatingconditions and displays the running or fault conditions of the condensing unit or rack.In order to ensure the safe and reliable operation of the unit and rack, the installation of Large ZX CondensingUnit and EMP Rack must comply with industry standards. The selection, installation and maintenance of LargeZX Condensing Unit and EMP Rack must be carried out by professionals. This user manual does not includeall industry guidelines for the installation of refrigeration equipment. For loss caused by inexperienced oruntrained personnel or due to wrong installation design, it will not be a reasonable reason for responsibility.If you have any questions, please contact the local sales office for unit or rack type and serial number on thenameplate for consultation. For example, the wiring diagram supplied with each unit or rack takes precedenceover the wiring diagram in this manual if any discrepancy occurs, please refer to the attached wiring diagram inthe unit or rack.ZX condensing unit introductionZX series condensing units have gained market popularity and have achieved great success in the Asian market withtheir energy-saving and friendly control experience. ZX/ZXB/ZXD/ZXL/ZXLD units in Asia are used on-site by famousend-users and cold chain retailers. ZX platform products have been widely recognized in the global market. Speciallydeveloped models have been exported to the United States, Latin America, Europe and the Middle East markets.Receiving your unitAll units are filled with dry nitrogen at a positive pressure before transportation. The unit and package are clearlylabeled. The unit shut-off valve is equipped with a maintenance interface to check the unit pressure maintenance.4Intelligent store solutions - A most innovative approach to enterprise facility management, EmersonIntelligent Store architecture integrates hardware and services, to provide retailers a single view into their entirework of facilities and understand what facilities actually cost to operate and maintain.The Intelligent Store architecture transforms data from store equipment and controls into actionable insights.Designed to deliver value in both new and existing stores, Emerson aims to help the retailers: Make better decisions on recources investment for greatest impact Gain accurate feedback and customized service to your specific needs Reduce operational costs and boost the profitability at most convenienceEnergy efficiency - Utilizing Copeland Scroll compressor technology, variable speed fan motor, large capacitycondenser coil and advanced control algorithms, energy consumption is significantly reduced. End-users can savemore than 20% on annual energy costs rather than using hermetic reciprocating units.Reliability - Combining the proven reliability of Copeland Scroll compressors with advanced electronics controllerand diagnostics, equipment reliability is greatly enchanced. Fault code alerts and fault code retrieval capabilitiesprovide information to help improve speed and accuracy of system diagnostics. Integrated electronics provideprotection against over-current, over-heating, incorrect phase rotation, compressor short cycling, high pressureresets, low pressure cut-outs. It can also send out a warning message to an operator when there is liquid floodback,which can prevent critical damage on the unit.Intelligent StoreBetter decision makingHighest efficiencyLower enery billsReliabilityLower maintenance cost5

InstallationLarge ZX CDU/EMP Rack are delivered with a holding charge of neutral gas. The condensing unit should belocated in such a place to prevent any dirt, plastic bag, leaves, or papers from covering the condenser and itsfins. The unit must be installed without restricting the airflow. A clogged condenser will increase the condensingtemperature, thus reducing the cooling capacity, which leads to a high-pressure switch tripping. Clean thecondenser fins on a regular basis.Pipe runs should be kept as short as possible, using the minimum number of directional changes. Use largeradius bends and avoid trapping of oil and refrigerant. This is particularly important for the suction line. Thesuction line should ideally slope gently towards the unit. Recommendation slope is 1/200 1/250. P traps,double risers and reduced pipe diameters may be required for suction lines where long vertical risers cannot beavoided.All pipes should be adequately supported to
