Samsung Electronics 48Disassembly and Reassembly3-2 Disassembly and Reassembly (cont.)3-2-5 Compressor exchange orderSTEP Occasion that compressor is 1 inside outdoor unit Occasion that compressor is 2 inside outdoor unit1 - Establish compressor to exchange by cutting.2 -Refrigerant release driving of applied outdoor unitఐ Refrigerant release driving enforces 1thnecessarily.Release driving that enforce contiguously can beresponsible for compressor breakdown.3 Lock all SVC valve of liquid pipe and gas pipe.4 Enter in vacuum mode and establish as all EEV and Valve open.5Reclaim refrigerant of outdoor unit using Recovery Unit.ఐ When there is no Recovery Unit, refer to below contents.1. If refrigerant release driving is enforced, refrigerant remaining amount of outdoor unit insideis about 1.5kg ordinarily. Temperature can remain more refrigerant because refrigerant fills toAccumulator in the winter day.2. Refer to factory charging refrigerant had registered to Label of outdoor unit.3. Can get help that decide an addition refrigerant quantity if use refrigerant quantity decisionfunction that use S-Checker.6 Turn off the power linked by outdoor unit.7Separate compressor that broke down from outdoor unit.ఐ Confirm through manifold gauge whether refrigerant of outdoor unit was reclaimed allnecessarily before use welding machine for replace of compressor.8 Measure quantity of broke down oil of compressor.9 Confirm state and color of compressor oil that broke down.10 -When is judged that oil was polluted, compressorbeside (ASTM : more than 3) measures quantity ofreplace and oil.11 Decide quantity of oil to pour in addition according to sheep of changing oil of compressors.12 Change by new compressor.Add oil according to sheep of oil that pour decided addition before.13 Establish again by vacuum mode after connect power.14 Execute leakage examination using nitrogen ࣖ vacuum work15 Add a refrigerant quantity deciding from step 5.16 Execute Auto Trial Operation after open SVC Valve.
