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.

Installation Copeland ZX condensing units are delivered with a holding charge of neutral gas. The condensing unit should be located in such a place to prevent any dirt, plastic bag, leaves or papers from covering the condenser and its fins. The unit must be installed without restricting the airflow. A clogged condenser will increase the condensing temperature, thus reduce the cooling capacity, and lead to a high-pressure switch tripping. Clean the condenser fins on a regular basis.
ZX Platform Condensing Unit Refrigeration connections Refrigeration piping installation All interconnecting pipes should be of refrigeration grade, clean, dehydrated and must remain capped at both ends until installation. Even during installation, if the system is left for any reasonable period of time (say two hours), pipes should be recapped to prevent moisture and contaminants from entering the system.

It is recommended that a clearance of 300 mm from the wall (or the next unit) be maintained from the unit’s left and rear panels whereas a clearance of 500 mm must be maintained from the unit’s right, top and front panels (seen facing the front of the unit).
ZX Platform Condensing Unit Start Up and Operation Before commissioning, ensure that all valves on the condensing unit are fully opened. Evacuation The evacuation procedure is based upon achieving an actual system vacuum standard and is not time dependent. Before the installation is put into commission, it has to be evacuated with a vacuum pump. Proper evacuation reduces residual moisture to 50ppm.
