Page 9: Application Limits And Operating Envelopes
2.4.2 Application limits and operating envelopes CAUTION Inadequate lubrication! Compressor breakdown! The superheat at the compressor suction inlet must always be sufficient to ensure that no refrigerant droplets enter the compressor. For a typical evaporator-expansion valve configuration a minimum stable superheat of at least 5K is required. The application envelopes for Digital refrigeration Scroll compressors are for various refrigerants, you can find them in the Copeland brand products Select software, which can be downloaded for free on our website www.emersonclimate.eu. -

Only the Copeland brand solenoid valve supplied as a requested accessory must be used. -
Page 12: Solenoid Valve Installation - General Recommendations
3.2.2 Solenoid valve installation – General recommendations The solenoid must be mounted vertically, within ± 15° of vertical. Horizontal mounting is not permitted. If a suction rotalock fitting is used, the threaded shipping plug in the rotalock fitting must be removed prior to brazing in the vertical solenoid line. -
Page 13: Vapour Injection (Evi = Economized Vapour Injection)
Copeland Scroll compressors ZFD13KVE to ZFD25KVE are vapour injection only. Liquid injection alone is not possible. For compressor model ZFD41K5E both liquid injection and vapour injection are possible. Dedicated discharge temperature thermostats (DLT) shall be used for R407A, R407F, R448A and R449A applications and can also be used for R404A. -
Page 14: Discharge Check Valve
Figure 13: Wet v apour inj ection cycle for R407A & R407F low temperature applications NOTE: For Digital compressors ZFD13KVE and ZFD25KVE, the DTC valve bulb must replace the existing NTC sensor located at the side of the compressor top cap. The previous NTC sensor has to be removed and the controller, eg, ALCO EC3-D*, has to be modified (disable discharge sensor input). -
Page 15: Shut-Off Valves And Adaptors
Copeland Scroll compressors have copper-plated steel suction and discharge tubes. These tubes are far more robust and less prone to leaks than copper tubes. Due to the different thermal properties of steel and copper, brazing procedures may have to be changed from those commonly used. shows the proper procedure for brazing Figure 17 the suction and discharge lines to a scroll... -
Page 16: Oil Separator
Braze connections can be converted to Rotalock by means of adaptors. Rotalock shut-off valves are available for the suction as well as discharge side. Using either straight or angled adaptors provides a way to convert a Rotalock into a brazing connection. Refer to Table 6 for proper tightening torques: Torque [Nm] Rotalock 3/4"... -
Page 17: Mufflers
3.10 Mufflers External mufflers, normally applied to piston compressors in the past, may not be required for Copeland Scroll compressors. Individual system tests should be performed to verify acceptability of sound performance. If adequate attenuation is not achieved, use a muffler with a larger cross-sectional area to inlet area ratio. -

Page 20: Terminal Box
4.2.1 Terminal box The standard terminal box is IP21 for all models with internal motor protection (TF*/PF*), enclosure class according to IEC 60034-5. Cable glands have an influence on the protection class of the terminal box. It is strongly recommended to use appropriate cable glands in order to reach the rated protection class. We advise installers/service providers to pay attention to this aspect every time they install or replace a Copeland Scroll compressor and to use cable glands according to EN 50262 or any other relevant standard of application in their country/region. -
Page 21: Motor Protection
4.2.3 Motor protection For ZBD21K* to ZBD114K*, ZFD13KVE to ZFD25KVE and ZFD41K5E compressors, conventional inherent internal line break motor protection is provided. 4.2.4 Protection devices Independently from the internal motor protection, fuses must be installed before the compressor. Selection of fuses has to be carried out according to VDE 0635, DIN 57635, IEC 269-1 or EN 60-269-1. -
Page 22: Low-Pressure Control
4.3.3 Low-pressure control IMPORTANT! Loss of system charge! Bearing malfunction! A low-pressure control is highly recommended for loss of charge protection. Do not bridge or by -pass the low-pressure cut out. Even though these compressors require a discharge temperature sensor, loss of system charge etc. -
Page 23: High Potential Testing
Emerson Climate Technologies subjects all Scroll compressors to a high-voltage test after final assembly. Each motor phase winding is tested, according to EN 0530 or VDE 0530 part 1, at a differential voltage of 1000V plus twice the nominal voltage. -
Page 24: Starting Up & Operation
Starting up & operation WARNING Diesel effect! Compressor destruction! The mixture of air and oil at high temperature can lead to an explosion. Avoid operating with air. IMPORTANT Oil dilution! Bearing malfunction! Turn the crankcase heater on 12 hours before starting the compressor. Strength pressure test The compressor has been strength-tested in the factory. -
Page 25: Initial Start-Up
the compressor before it runs. The majority of the charge should be placed in the high side of the system to prevent bearing washout during first-time start on the assembly line. Initial start-up CAUTION Oil dilution! Bearing malfunction! It is important to ensure that new compressors are not subjected to liquid abuse. -
Page 26: Deep Vacuum Operation
To establish the minimum run time obtain a sample compressor equipped with a sight tube (available from Emerson Climate Technologies) and install it in a system with the longest connecting lines that are approved for the system. The minimum on time becomes the time required for oil lost during compressor start -up to return to the compressor sump and restore a minimal oil level that will ensure oil pick -up through the crankshaft. -
Page 27: Oil Level
5.15 Oil level The oil level should be maintained at mid-point of the sight glass. If an oil regulator is used the level should be set within the top half of the sight glass. 5.16 Digital system control Due to the pulsing characteristic of Copeland Scroll Digital compressors superheat control needs to be performed by qualified solutions in order to assure the stability, reliability and good performance of the system. -
Page 28: Maintenance & Repair
Maintenance & repair Exchanging the refrigerant Qualified refrigerants and oils are given in section 2.4.1. It is not necessary to replace the refrigerant with new unless contamination due to an error such as topping up the system with an incorrect refrigerant is suspected. To verify correct refrigerant composition, a sample can be taken for chemical analysis. -
Page 29: Lubrication And Oil Removal
Compressors supplied by Emerson Climate Technologies contain oil with low moisture content, and it may rise during the system assembling process. Therefore, it is recommended that a properly sized filter drier is installed in all POE systems. -
