 Caution on piping handling:
(1)Protect the open end of the pipe against dust and moisture.
(2)All pipe bends should be as gentle as possible. Use a pipe bender for bending.
(Bending radius should be 30 to 40mm or larger.)
Selection of copper and heat insulation materials:
 When using commercial copper pipes and fittings, observe the following:
(1)Insulation material: Polyethylene foam
Heat transfer rate:0.041 to 0.052W/mK(0.035 to 0.045kca/(mh℃)
Refrigerant gas pipe's surface temperature reaches 110 max.
Choose heat insulation materials that will withstand this temperature.
(2) Be sure to insulate both the gas and liquid piping and to provide insulation dimensions as
below.

(3)Use separate thermal insulation pipes for gas and liquid refrigerant pipes.
 Checking for gas leakage
(1)Check for leakage of gas after air purging
(2)See the sections on air purges and gas leak checks in the installation manual for the
outdoor unit.
 Attaching the connection pipe
 Attach the pipe after checking for gas leakage, described above.
(1)Cut the insulated portion of the on-site piping, matching it up with the connecting portion.
(2)Secure the slit on the refrigerant piping side with the butt joint on the auxiliary piping
using the tape, making sure there are no gaps.
(3)Wrap the slit and butt joint with the included insulation sheet, making sure there are no
gaps.
