Page 25: Low Ambient Operation
8.5 LOW AMBIENT OPERATION Even if the compressor can work in low ambient conditions, the system may require specific design or recommendations to ensure compressor working conditions to remain inside the application envelop. In the low ambient temperature, normally, the cooling load will be lower. To avoid the liquid flood back. during the operation, the expansion device should be designed to maintain the minimum and stable superheat. -
Page 26: Crankcase Heater
10-13 HP 10.5 SE scroll compressors are tolerant to liquid refrigerant, despite it, Embraco recommends avoiding this running condition. If the refrigerant charge is higher than the limits listed in the upper table, it is recommended to use additional protections in the system to ensure proper running conditions (piping design, suction accumulators, crankcase heaters, pump down). -
Page 27: Accumulators
8.8 ACCUMULATORS Due to the inherent ability of scroll to handle liquid refrigerant in flooded start and defrost cycle operation conditions, accumulators may not be required. An accumulator is suggested on single compressor 2-6 hp systems when the charge limitations exceed 4.5kg, and on the single compressor 7-12 hp systems when charge limitations exceed 8kg. -

Page 33: Solenoid Valve
9.7 SOLENOID VALVE A solenoid valve with a minimum 3mm orifice must be provided in the injection circuit that opens whenever the compressor is operative or cooling is required during pump down. The solenoid must be closed when the compressor is cycled off. Note: Not required if DTC valve is used. -
Page 34: Suggested Application Techniques
Figure 9.9 Assembly of valve bulb 9.10 SUGGESTED APPLICATION TECHNIQUES For the most efficient thermal sensing, spread a thin film of thermal grease around the DTC Valve bulb before installing into the top cap well. However for proper functioning of the valve this is not required. At your discretion, field serviceability can be improved by installing a shut-off valve in the liquid line just before the DTC Valve. -

Page 49: Electrical Insulation
10.18 ELECTRICAL INSULATION All compressors are tested for dielectric strength and electrical insulation to ground according to requirements IEC/EN 60335-2-34 (to be used with IEC/EN 60335-1) (latest edition). Note: dielectric strength and compressor insulation to ground are different when the compressor is tested in the air or in a system charged with refrigerant, due to the dielectric characteristics of the refrigerant. -
Page 50: System Evacuation
11.3 SYSTEM EVACUATION An important step in effectively cleaning a system before operation is proper evacuation. Air is very detrimental to refrigeration systems and must be removed before start up and after field service. Blowing out lines with dry nitrogen may remove a major part of the air from a system, but if air is trapped in the compressor during installation it is practically impossible to remove from the compressor by purging with nitrogen. -
Page 51: Charging Process
The quantity and type of oil charged into the compressors are indicated in the compressor label and Technical datasheet in the Embraco Product Selector on www.embraco.com Oil used with scroll compressors is Polyolester (POE) Emkarate RL32H and is applicable for all approved refrigerants used with compressor. -
Page 52: Oil Management For Rack Application
11.7.1 OIL MANAGEMENT FOR RACK APPLICATION Scroll refrigeration compressors may be used on multiple compressor parallel rack applications. This requires the use of an oil management system to maintain proper oil level in each compressor.

For conditional approval of specific cases please contact Embraco Logistics or Technical support team. - Page 62 APPENDIX 1 SAFETY RECOMMENDATIONS FOR COMPRESSOR INSTALLATION Flammable – risk of fire. High voltage – risk of electric shock. Toxic – risk of intoxication. GENERAL RECOMMENDATIONS Only trained personnel can perform diagnostic and maintenance procedures on refrigeration systems. Installation and repair requires special training, technical information, special tools and special equipment.
- Page 63 Failure to disconnect the compressor from the mains may, in the event of a short circuit in the region of the hermetic terminal of the compressor, cause expulsion of the hermetic pins causing leakage of the cooling fluid. 1 • ELECTRICAL ACCESSORIES Before removing the protective plastic cover from the electrical components, check if the compressor is disconnected from the mains and that starting and / or running capacitors are used.
- Page 64 Not specified relay starting device may cause the capacitor to overheat. Overheated capacitors are subject to rupture which can lead to leakage of overheated material that can lead to burns. The use of relay starting device other than specified can generate short circuit in the hermetic compressor terminal, causing the expulsion of hermetic pins causing refrigerant and oil leakage.
- Page 65 In the case of two-phase installations, it is mandatory to use a 2-pole circuit breaker, because in case of a short circuit both phases of power supply are protected. The system must be grounded. Failure to use a 2-pole circuit breaker leaves the compressor susceptible to short circuit in the region of the hermetic compressor terminal, which may cause the hermetic pins to WARNING be ejected causing the refrigerant and oil to leak.
- Page 66 2 • COMPRESSOR If you need to replace the compressor, be aware of the following safety recommendations: Make sure the compressor is disconnected from the mains. Failure to shut down the compressor from the mains during maintenance procedures may expose the technician to risk of electric shock and fire. Never remove the compressor before removing all refrigerant from the system.
