ZX CDU Intelligent Store Solution Module ZX CDU address is determined using dip switches on the Intelligent Store Solution Module. Switch numbers 1 to 6 set the slave address. Switch number 7 will set the Baud rate and switch number 8 will set the parity. The range of allowable addresses is 1 through 63.

Termination Resistor for XWEB300D If XWEB300D is placed at the beginning or at the end of the line, please install its termination resistor by adding a jumper in position 2 (JMP2 on the back side of the unit). Do not add the jumper if XWEB300D is placed in the middle of the RS485 line.
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.
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 re- capped to prevent moisture and contaminants from entering the system.
Expansion Valve Selection for Low Ambient Application For systems expected to operate in varying ambient conditions – namely summer and winter temperatures – the expansion valve (TXV or EXV) sizing should take into consideration the maximum expected saturated condensing temperature at high ambient conditions (summer) and the minimum expected saturated condensing temperature, set at -25°C, during low ambient conditions (winter).
Oil charging procedure Emerson ZX condensing units are supplied only with a compressor oil charge. After commissioning, the oil level should be checked and topped up if necessary. The oil level should be approximately halfway up the sight glass (ZXL/ZXD units). Oil can be charged through the Schraeder valve on suction valve.
