General instructions WARNING System breakdown! Personal injuries! Never install a system in t he f ield and leave it unattended when it has no charge, a holding charge, or with t he service valves closed without electrically locking out the system. System breakdown! Personal injuries! Only approved ref rigerants and ref rigeration oils must be used. -

5K is required. In the same way, the superheat at the compress or suction must always stay below a maximum limit specif ied by Emerson, depending on the model and for which the operating envelope is defined. - Page 8 This can be achieved by the use of wet vapour injection. For further information about wet vapour injec tion, c ontact A pplicat ion Engineering at Emerson. NOTE: For information and design recommendations regarding vapour injection, please refer to Technical Information C7.4.3 "Vapour injection scroll compressors for heat pumps".

Page 11: Installation
The suction stub on compressor models ZHI27K1P to ZHI46K1P is located at low level. Oil might f low through the suction stub and get trapped in the syst em. To avoid t his, Emerson s trongly recommends mounting the suction piping turning vertically upward f rom the compressor connection. -
Page 12: Mounting Parts
For multiple compressor parallel configurations, the compressors must be positioned c ompletely vertically on a totally horizontal surface or rail. Mounting parts The compressors are designed to be mounted on vibration absorber grommets (part of the standard delivery). The grommets dampen the start-up surge of t he compressor and minimis e sound and vibration transmission to the compressor base during operat ion. -

Page 14: Crankcase Heaters
This will prevent oil dilution and bearing stress on initial s tart -up. The crankcase heater must remain energized during compressor off cycles. NOTE: Please refer to the Spare Parts list available at www.climate.emerson.com/en- gb/tools-resources to select the correct crankcase heater model. Caution: Crankcase heaters must be properly grounded! For installation, the manufacturer/installer shall follow the recommendations mentioned below. -
Page 15: Soft Starters
However, f or extreme electrical conditions such as weak power supplies, single-phase soft starters can be supplied on request by Emerson, while three-phase sof t starters are available on the market. Discharge gas temperature protection... - Page 16 EXD TEVI (contact Emerson for more information). The controller has to stop the compressor when the maximum discharge gas temperature is exceeded.
-
Page 17: Excessive Discharge Gas Temperatures
Since Copeland scroll compressors have a very high volumetric efficiency their displacements ar e lower than those of equivalent capacity reciprocating compressors. As a result, Emerson recommends that the capacity rating on reversing valves be no more than 1.5 to 2 times the nominal capacity of the compressor in order to ensure proper operat ion of t he rev ersing v alv e under all operating conditions. -
Page 18: Sound And Vibration
(two, three, or more) require additional oil balancing qualif ication between the parallel compressors. A sample compressor equipped with an external oil sight tube can be ordered from Emerson for lab testing. Records of the evaporating temperature and the bottom shell temperature s hall be t ak en wit h a high sampling rate during the entire oil return or oil balance testing and under all tested conditions. -

Page 24: Motor Winding
4.2.3 Motor winding The ZH scroll compressors are offered with either a single-phase or a three-phase induction motor, depending on the size. All three-phase motors are connected in star; single-phase motors need a run capacitor. Motor insulation The motor insulation material is class "B" (PF* and TF*) or "H" (TW*) f or compressor models covered in these guidelines. -

DO NOT USE other industrial gases. 5.1.1 Compressor strength-pressure test The compressor has been strength-pressure tested in the Emerson factory . Theref ore, i t is not necessary for the system manufacturer/installer to strength-pressure test the compressor again. -
Page 28: Preliminary Checks - Pre-Starting
All compressors get a factory holding charge of dry air (about 1 to 2.5 bar, relativ e press ure). A n intact holding charge serves as a proof of quality against penetrating moisture. When removing plugs from the compressor, the plugs may pop out due t o p ressure and oil can spurt. -
Page 29: Rotation Direction
Rotation direction Scroll compressors, like several other types of compressors, will only compress in o ne rot ational direction. Direction of rotation is not an issue with single-phase compressors since they will always start and run in the proper direction. All three-phase compressors will ro tat e in eit her direct ion depending upon the phasing of the power. -
Page 30: Pump-Out Cycle
5.12 Minimum run time Emerson recommends a maximum of 10 starts per hour. There is no minimum of f t ime b ecause scroll compressors start unloaded, even if the system has unbalanced pressures. The most critical consideration is the minimum run time required to return oil to the compressor af t er s tart -up. -
Page 31: Oil Level
During the system development, adequate oil return in any operation should be checked what ever the compressor model. For this purpose, sample compressors equipped with sight t ubes can b e ordered from Emerson. Oil return check test recommendations are also available on demand f rom Application Engineering. -
Page 32: Maintenance & Repair
Maintenance & repair WARNING Conductor cables! Electrical shock! Follow the lockout/tag out proc edure and the national regulations before carrying out any maintenance or serv ic e work on the system. Use compressor with grounded system only. Screwed electrical connections must be used in all applications. -

Page 35: Troubleshooting
Troubleshooting WARNING Electrical connections! Electrical shock hazard! Before at tempt ing any electrical troubleshooting, make sure all grounds are connected and s ecure and there is ground continuity throughout the compressor system. Also ensure the compressor system is correctly grounded to the power supply. If you are not a qualified service person familiar with electrical troubleshooting techniques, DO NOT PROCEED until a qualified service person is available. - Page 36 Condition Cause Corrective action Compressor Check if there is continuity on the compressor external motor protector. If the compressor is warm, it may require protector open considerable time to cool down. Def ective Check if the pressure control or thermostat works system control properly or if the controls are open.
