 Reinstall should pay attention to the following aspects: 1, terminals or other wiring is loose, to prevent the occurrence of ignition or other hazards, wire 
 Aging, if aging must if replacement; 
 2, check the connection pipes, joints whether tainted fluorine phenomenon, used a period of time machines, such as tainted fluoride phenomena in general there will be leakage of oil-; 
 3, measure the insulation resistance of the air conditioner to prevent the air conditioner leakage phenomenon appears; 
 4, the outlet pipe drainage is reasonable; 
 5, cleaning filters, air duct system; 
 Eight, air conditioning repair installation is complete, the test machine to measure the following aspects of the data and make records: 
 1, the presence of abnormal noise; 
 High pressure and low pressure; 
 3, the air inlet temperature and outlet temperature, temperature difference between indoor and outdoor ambient temperature; 
 4, the power supply voltage;
