Air-conditioner and Heater BF-23 Oil of the Compressor Keep enough oil in the compressor. The lubricating oil and the refriferant circulate in the inner system, when change the component or the oil leaks a lot, please add the oil to the requirement capacity. If the oil capacity is not proper, the compressor will be Short of oil: the cylinder of the compressor may be nicked by the piston or the compressor may be locked-up Excessive oil:the effect of the refrigeration may go down Capacity of the adding oil Check the operational function Its purpose is to check if the system worked under the requirements. These parts need to check: blower(fan), circulation of the operational-mode( outlet), inlet, temperature lower,and upper, and the A\C switch. Checking condition: The engine is running and the temperature is in normal condition. Approach: 1.Check the blower(fan) Move the fun switch to the "1" position, the fan should be in the speed of "1"; Then move to the "2" position; Check the other speed of the fan; 2.Chexk the ventilation Move the switch to the position, check if the air is blown to your face; Move the switch to the position, check if the air is blown to your face and feet; Move the switch to the position, check if the air is blown to your feet; Move the switch to the position, check if the air is blown to your feet and defrost; Move the switch to the position, check if the air is vented from the defroster. substitute part capacity (mm) ratio (%) evaporator 45~75 30 — condenser 30~50 20 — oil storage container 15~25 10 compressor, no change others 30~50 — leak a great deal — — leak a little bit |
