ZX Platform CDU
Disclaimer
Thank you for purchasing the ZX platform condensing unit from Emerson Climate Technologies. ZX platform CDUs are the best in class
within the capacity and operating range available in the market. ZX CDU is designed to operate reliably and to deliver high operating
efficiencies in medium and low temperature refrigeration applications. It also provides constant monitoring of the compressor operating
conditions and displays the running or fault conditions of the CDU. ZX platform CDUs have to be installed by following the industry trade
practices for its safe and reliable operation. It is assumed that the CDU is selected, installed and serviced only by professionals. The user
manual does not cover good industry practices which are essential on a refrigeration equipment installation. No responsibility can be
accepted for damage caused by inexperienced or inadequately trained site technicians or improper installation design.
If in doubt, please consult your local sales office, quoting unit model and serial number as shown on each unit nameplate. In case of any
ambiguity, the wiring diagram supplied with each unit takes precedence over the diagram in this manual.
Introduction to ZX Platform CDU
ZX medium temperature, ZXD digital medium temperature and ZXL low temperature series have been highly successful and enjoys
proven success with its energy savings and customer-friendly electronic features. ZX, ZXD and ZXL CDUs have been applied by several
well-known end-users and chain retailers. The ZX platform is also gaining wider acceptance in the global market and specific variants
have been developed and exported to the USA and to the European and Middle East markets.
Receiving your unit
All units are shipped with a holding charge of dry nitrogen inside at a low but positive pressure. Suitable labeling is prominently
displayed on both the unit and the packaging. Service connectors are provided on the CDU service valve for the convenient checking of
the integrity of the holding charge.
It is very important to check that this holding pressure exists at the time you receive each unit from us or our authorized
representatives. Please inform us or our authorized representative if the holding charge is non-existent. Failure to do so could void the
claim for other related system faults at a later period.
Transit damage is essentially an insurance claim and is not covered under manufacturing defect. It is also advisable to inspect the rest of
the unit for obvious physical damage and inform us or our authorized representative in case any is discovered.
ZX Platform Condensing Unit was designed based on three factors demanded by industry users:
Intelligent Store Solutions
-
A most innovative approach to enterprise facility management, Emerson’s Intelligent Store™
architecture integrates hardware and services, to provide retailers a single view into their entire network of facilities and understanding
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 recourses investment for greatest impact
•
Gain accurate feedback and customized service to your specific needs
•
Reduce operational costs and boost the profitability at most convenience
Energy Efficiency
- Utilizing Copeland Scroll™ compressor technology, variable speed fan motor, large capacity condenser coil and
advanced control algorithms, energy consumption is significantly reduced. End-users can save more than 20% on annual energy costs
rather than using hermetic reciprocating units.
Reliability
- Combining the proven reliability of Copeland Scroll compressors with advanced electronics controller and diagnostics,
equipment reliability is greatly enhanced. Fault code alerts and fault code retrieval capabilities provide information to help improve
speed and accuracy of system diagnostics. Integrated electronics provide protection against over-current, over-heating, incorrect phase
rotation, compressor cycling, high pressure resets, low pressure cut-outs. It can also send out a warning message to an operator when
there is a liquid floodback, which can prevent critical damage on the unit.
Caution!
