CHAPTER 5.
AYXPC18LR DISASSEMBLING PROCEDURE
If, in carrying out repairs and modifications, the work requires the use of arc- and flame-producing apparatus, such as welding, brazing and soldering
equipment, this work shall only be started after the rooms have been thoroughly ventilated. While the work is being carried out, the mechanical venti-
lation, if any, shall be kept in constant operation and all windows and doors kept open. In the case of repairs to parts of the refrigerant circuit, it may
be necessary that not only the workman but also a second person shall be present for observation and assistance.
Necessary protective equipment shall be available and, in the case of open flames or arcs, fire extinguishing apparatus shall be ready to hand.
Welding and brazing shall be carried out by qualified workmen.
Be sure to disconnect the power cord from the AC power outlet before starting the disassembly procedure. When reassembling the unit after repair-
ing, be sure to install screws to their original positions.
The screws used are not the same in specifications such as corrosion-resistant treatment, tip shape and length.
After the air conditioner is repaired or parts are replaced, measure insulation resistance of the equipment using an insulation resistance meter. If the
measured resistance is lower than 1 MΩ, inspect parts and repair or replace defective parts.
