10 This guide contains many important safety messages. Always read and obey all safety messages. You can be killed or seriously injured if you don t follow instructions. 3.2 Application Limit Ref. No. LGETA Issued Date Rev. No. Rev. 0 Rev. Date - Refrigerant Charge Limit Cooling Only for SRAC system : 1866g Max (Charge limit depends on Oil Dilution Rate * note 1 & accumulator K ) Liquid Refrigerant Back Δ T : Temp. Difference System should be designed not to allow the liquid to go back to compressor which cause knocking noise, current increase or undesirable vibration and make short compressor life time. Δ T = Case Bottom Temp.- Condensing Temp. It must be kept Δ T 5 Pressure Difference in Operating ON/OFF Operation The Pressure difference in operating shall be 5.0 kg f/ cm2 or more, but 3 minutes starting excluded. Each cycle should be at least 6 minutes (ON Time : at least 3 minute, OFF Time : at least 3 minutes) Pressure Difference at Starting Tilt in Operation When starting, discharge pressure is balanced with suction pressure. ( Pd Ps 0.5 kg f/ cm2 ) The allowable tilt of the compressor in operation shall be 5 or less. The Accumulator volume should be enough to cover 30% of maximum system refrigerant volume. Ratio coefficient K should be over 0.6(heating system) or 0.4(cooling system) System Accumulator Volume of Accum.(Comp+System) Specific gravity of Refrigerant K = Charged Weight of Refrigerant Effective volume of compressor accumulator =597 cm3 Specific gravity of refrigerant (R22) = 1.25 g/ cm3 ( at 20 ) If coefficient K does not meet recommendation, refrigerant system must check liquid back phenomenon at accumulator. Protecting Reverse Operation The compressor must be operated by proper voltage in accordance with the frequency without reverse revolution condition. The reverse revolution condition can be avoided by just keeping right order of phase supplied power source. 9 / 13

11 Ref. No. LGETA Issued Date Rev. No. Rev Application Limit Rev. Date - Frequency Range Rated Frequency ±2% Pipe Stress Don t allow any force on discharge & suction pipe. The piping stress must be less than 300 kg f/ cm2 at starting and stopping. And less than 153 kg f/ cm2 at running. Oil Level Protection device It must be checked oil level by the compressor with sight glass we supply. And oil level must be kept over guide line level ** note 2. at any condition. Refrigeration system must has the compressor protection device like over pressure, high temperature, sensing locked pump in the controller. When starting & running fail by abnormal overload, controller must be able to cut off power of compressor before motor burn out. An earth terminal should be installed to prevent electrical accidents. Pump down refrigerant If pump down time is too long, compressor can be damaged due to excessive temperature increase or poor lubrication. Guideline of pump down process. - Time : less than 30 seconds - Suction Pressure : It should not run under below 1 kg f/ cm2 G. And before closing a service valve, compressor running for more than 5 minutes is recommended. If gas charge amount of refrigerant specified is exceeded, both parties should discuss the matter to determine compressor specification. (accumulator volume, lubricating oil amount) and system specifications (crank case heater, oil separator, additional accumulator, etc) * Effective Period of This Document * This document will be effective after LG s receipt with your authorized signature.

12 Ref. No. LGETA Issued Date Rev. No. Rev Process Limit Use defined Refrigerant and oil Avoid Damage running Running dummy indoor Prevent oxidation in pipe Charging Refrigerant Avoid Vacuum running Avoid Air compression Promptly Assemble compressor in line Wiring Rev. Date - Any process in where the HCFC s refrigerant or the different kind of oil against the defined. Compressor oil are mixed should be avoided. The running operation that inspection and the protector inspection that affect a damage to the function and durability of the compressor should be avoided When the outdoor unit is operated with the indoor dummy unit, the discharged oil should be recovered enough Always purge the system and the compressor with the dry nitrogen in order to prevent oxidation of the piping When charging refrigerant into the cycle, make sure that refrigerant always be filled from the higher pressure side (condenser exit) of the cycle. If liquid refrigerant is sucked in to the compressor liquid compression occurs, The discharge valve is damaged, lubrication effectiveness degenerates and reliability drops noticeably Do not operate the compressor in a vacuum state. Furthermore do not apply high voltage to a vacuum state compressor. There is a danger that insulation could degenerate, causing electric shock Do not compress the air including the case of leakage in the refrigeration cycle. If compressors run with air mixed, inside the compressor is heated and pressurized, which may cause an explosion After removing rubber plugs from compressor tubes, Promptly use the compressor. And do not leave in the atmosphere for 10 minutes over. If Air gets into the compressor, accelerating degeneration of the inside of the cycle or compressor Wires connected to the compressor, follow the compressor specification manual and instructions Storage temperature -10 ~ / 13
