1. Precautions1-1 Precautions for the ServiceUse the standard parts when replacing the electric parts. – Confirm the model name, rated voltage, rated current of the electric parts.Repair the disconnection of HARNESS securely when repairing the break down. – If there is any connection error, it causes an abnormal noise and incorrect operation.In case that you assemble or disassemble the products with laying it on the side, do work on the work cloth. – If not, the exterior of products can be scratched.Remove dust and foreign materials from harness, connection part, and inspection part thoroughly when repairing the break down. – It protects the danger of fire such as tracking and short.Tighten tightly the service valve of outdoor unit and the cap of charging valve with a monkey spanner. Check the assembly status of parts after repairing the break down. – It should be same as the status before repairing. 1-2 Precautions for the Static Electricity and PL As the PCB power terminal has a weakness for the static electricity, pay attention to it during the repair and measurement. – Work with insulation gloves during the repair and measurement of PCB. Check the distance between the product and the other electronic appliances such as TV, video, and audio. It should be over 2m. – If not, it causes a bad picture quality or a noise. Repairing the products by consumer should be strictly prohibited. – There is a danger of electric shock or fire due to incorrect disassembly.1-3 Precautions for the Safety Do not pull any electric wires and do not touch an auxiliary power switch with a wet hand. – There is a danger of electric shock or fire. In case any wire or power plug has been damaged, replace it to eliminate any possible danger. Do not bend the power cord by force and do not put any heavy object on the power cord. – There is a danger of electric shock or fire. Do not use multi socket. – There is a danger of electric shock or fire. Ground the product if necessary. – Be sure to ground the product if there is any danger of electric leakage due to water or moisture. Be sure to turn off the auxiliary power switch or pull out the power plug during replacement or repair of electric parts. – There is a danger of electric shock. In case the product will not be in use for a long time, the battery of remote control should be kept separately. – Leakage of inside fluid can cause break down of remote control.
