Disassembly and Reassembly3-18Samsung Electronics■ Point to consider at compressor exchange1) Oil color decision (availability of that change compressor that is beside at the same time) of compressor that broke down.- Decide that exchange all 2 that exchange side that broke down after judge state of oil by below photograph colorextracting oil in compressor that broke down in case of exchange compressor.- ASTM = exchange all 2 more than 3.- Normalcy Clamping force of bolt that fix compressor is 3 ± 0.5 N-m.2) Weight of compressor and quantity of oil- When compressor is shipped at factory, oil of (compressor unit standard) 1100cc was filled up.- GB052FAVA of weight of compressor including oil is 31.6kg, and GB066FAVA is 35.4kg.- Add oil to outdoor unit as much as relevant weight if is heavy than weight of compressor that weight of compressor thatis changed to locality is changed newly.- Quantity(kg) of added oil = Weight(kg) of compressor that broke down - Weight(kg) of newly change compressor- If quantity of calculated addition oil passes over 1kg, quantity of add oil does by 1kg.- Problem of that is blocked in oil circulation of (remaining oil of compressor that broke down below 0.3kg) compressor if is lightmore than 0.8kg than weight of compressor that weight of compressor that is changed to locality is changed newly inspects oilcirculating system because possibility occurred is high.3) Checking of oil circulating system① Oil separator capillary tube or filter of block- If filter or capillary tube of oil separator lower column is blocked by alien substance etc.., can become cause of compressor breakdownbecause oil is not collected.- Can doubt that is blocked if oil separator capillary tube temperature is low after refrigerant outlet temperature of compressor, in driv-ing, rises.( ※ Compressor 2 individual occasion oil separator capillary tubes each other cross.)- Confirm that is blocked in stationary state through nitrogen pressurization availability.② Breakdown of Accum Oil Return Valve (ARV)- Damage can become cause of compressor breakdown because oil is not collected if filter of valve front/piping etc.. is blockedwith ARV is closed.- Power connector of ARV confirms that was linked right.- Extract connector in vacuum mode or confirm whether when insert, action sound of valve happens.③ When CCH is badness, can become cause of compressor breakdown by oil foaming.▶ Change to compressor that is beside.
