Page 4: About These Guidelines
Manufacturer’s Declaration, available relevant standards please refer www.climate.emerson.com/en-gb. These instructions should be retained throughout the lifetime of both the compressor and the refrigeration unit. You are strongly advised to follow these safety instructions. Icon explanation WARNING CAUTION This icon indicates instructions to avoid This icon indicates instructions to avoid personal injury and material damage. -
Page 5: General Instructions
General instructions WARNING System breakdown! Personal injuries! Never install a system in the field and leave it unattended when it has no charge, a holding charge, or with the service valves closed without electrically locking out the system. System breakdown! Personal injuries! Only approved refrigerants and refrigeration oils must be used. -

Page 10: P&I Diagram For Zxle Units
2.8.2 P&I diagram for ZXLE units IMPORTANT Absence of insulation on the liquid line in ZXLE units! Air moisture condensation and lack of performance! Moisture will condensate on the liquid line and cause water droplets. The liquid line can pick up additional heat from the ambient which will adversely affect the subcooling desirable for the liquid refrigerant before it enters the expansion valve. -

Page 12: Main Control & Safety Features
2.10 Main control & safety features Copeland ZX Small refrigeration units feature a whole range of control and safety components. 2.10.1 Suction pressure control The unit is switched on and off by means of a PS1 low-pressure switch. Caution: The unit does not have any cycling protection. The adjustment of the low-pressure switch must be done in such a way that the unit will not switch on and off more than 10 times per hour during normal operation. -
Page 13: Installation
Installation WARNING High pressure! Injury to skin and eyes possible! Be careful when opening connections on a pressurized item. Copeland ZX Small refrigeration units are delivered with a holding charge of dry air at 1.68 bar. The refrigeration unit should be located in such a place to prevent any dirt, dust, plastic bag, leaves or papers from covering the condenser and its fins. -
Page 14: Brazing Recommendations
IMPORTANT Connection sizes! Unsuitable refrigerant flow rate! Do not assume that the service connection sizes on the unit (at the service valves) are in fact the correct size to run your interconnecting refrigeration pipes. The service valve sizes have been selected for convenience of installation and in some cases (larger units) these may be considered too small. -
Page 15: Brazing Procedure
Figure 7: Brazing – Sectional view 3.2.3 Brazing procedure For the brazing of the tubes, please refer to Figure 8 and procedure hereunder: ▪ Fit the copper tube into the unit tube. ▪ Heat area 1. As the tube approaches brazing temperature, ▪... -
Page 16: Maximum Operating Currents For Cable Selection
All accessible metallic parts or objects within 3 metres of the refrigeration unit, eg, metal pipes, fence, ladders, railings etc... must be grounded with a dedicated grounding connection. A separate ground connection is provided on the baseplate of the unit. Figure 9: Additional ground connection on the unit baseplate After commissioning, make sure to reconnect the ground wire to the front cover. -

Page 18: Start-Up & Operation
Start-up & operation Before commissioning, ensure that all valves on the refrigeration unit are fully opened. Evacuation CAUTION System pressure below atmospheric pressure! Compressor damage! Never energize the unit without minimum refrigerant charge in the system. There is a risk of malfunction of the unit in deep vacuum operation which can cause compressor damage. -
Page 19: Oil Charging Procedure
NOTE: The oil level should be approximately halfway up the sight glass. As mentioned in paragraph 2.6.1 "Qualified refrigerants and oils", Emerson recommends using one of the following oil types: ▪... -

Checks before starting & during operation IMPORTANT Liquid valves not fully opened! Liquid trap! The valves on the liquid line should be fully open, in order to prevent liquid trapping. Before a system runs for the first time: ▪ Check that the valves on the liquid line are fully open. ▪... -
Page 21: Maintenance & Repair
NOTE: For more information about unit components and spare parts, please refer to the compressor application guidelines and to the Copeland Spare Parts Catalogue available at www.climate.emerson.com/en-gb/tools-resources. Safety devices During regular maintenance, all mechanical safety devices such as high- and low-pressure switches must be checked for proper functioning and triggering at adjusted setpoints. -
Page 22: Electrical Connections
NOTE: In order to meet the requirements of the Ecodesign Directive 2009/125/EC with regard to efficient system operation, ensure the heat exchangers remain clean at all times. Electrical connections WARNING Isolating switch "On"! Danger of electric shock! Before undertaking any task on electrical equipment, turn off the main power supply to de-energise the unit. -
