Page 197 2-4. Selection of pipe heat insulating material Always insulate the refrigerant pipe to prevent condensation and water droplets by the refrigerant pipe. For selection of pipe heat insulating material, refer to following items. • Decide the thickness of the heat insulating material by referring to the recommended minimum thickness in Table 1.
Page 198 2-5. Additional charge calculation CAUTION • Do not turn on the power unless all operations are complete. • After evacuating the system, add refrigerant. • Do not charge the system with a refrigerant other than R410A. • Always keep to the limit on the total amount of refrigerant. Exceeding the limit on the total amount of refrigerant will lead to malfunction during charging of refrigerant.
Page 199 ¢ If additional refrigerant is required When the piping is longer than pre-charge length, additional charging is necessary. 1. Remove the charging cap from the liquid pipe. 2. Attach a charging pipe hose to the refrigerant cylinder, and connect it to the charging port. 3.

Page 203 3. Pipe installation 3-1. Caution of piping CAUTION Keep the permissible length of every piping limitation to prevent a defect or cooling/heating failure. • Piping material: – Use the designated size (diameter and thickness) of refrigerant pipes. – Those pipes purchased locally may contain dust inside. Blow out the dust by dried inert gas when using.
Page 204 CAUTION • Brazing: – While brazing the pipes, be sure to blow dry nitrogen gas through them. – If nitrogen gas is not blown through the pipes while they are being brazed, an oxidized layer may form on the inside of the pipes. If this occurs, the cooling efficiency may decrease and the air conditioner unit (compressor, valves, etc.) cause malfunction.
Page 205 3-2. Piping to outdoor unit ¢ Knocking out procedure in piping CAUTION • Be careful not to deform or scratch the panel while opening the knock out holes. • To protect the piping insulation after opening a knock out hole, remove any burrs from the edge of the hole.
Page 206 3-3. Pipe connection ¢ Precautions for connecting simultaneous operation multi CAUTION • Use genuine branch pipes for the refrigerant piping branches. Branch pipes are twin or triple type for simultaneous operation, and may be used for piping between the outdoor and indoor units.
Page 207 ¢ Removing the pinch pipes WARNING Remove the pinch pipe only when the internal gas is completely drained as shown on the below instructions. If gas still remains inside, the piping may crack if you melt the brazing filler metal of the junction area with burner.
Page 208 ¢ Connecting the pipes CAUTION • Seal the pipe route hole with putty (locally purchased) such that there are no gaps. Small in- sects or animals that are trapped in the outdoor unit may cause a short circuit in the electrical component box.

When connecting the main piping, do not bend it near the connection section. If the main pipe must be bent due to unavoidable circumstances, ensure that the linear section is 10 times or more than the diameter of the connection piping.
Page 213 After brazing the pipes, use the supplied heat insulation to insulate them. a. Remove the protective sheet from the double-stick tape that is affixed to the heat insula- tion. b. Use tape (locally purchased) to seal the seam so that there will be no gap at the junction between the aforementioned heat insulation and the heat insulation on the local piping.
