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 efciencies 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 ofce, 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, ZXB medium temperature, ZXD digital medium temperature and ZXL low temperature series have
been highly successful in the Asian market and enjoys proven success with its energy savings and customer-friendly electronic
features. ZX, ZXB, ZXD and ZXL CDUs have been applied by several well known end-users and chain retailers throughout Asia.
The ZX platform is also gaining wider acceptance in the global market and specic 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.
Caution! 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 specic needs
• Reduce operational costs and boost the protability at most convenience
Energy Efficiency - Utilizing Copeland Scroll
TM
compressor technology, variable speed fan motor, large capacity condenser
coil and advanced control algorithms, energy consumption is signicantly 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
TM
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 oodback, which can prevent critical damage on the unit.
