OUTDOOR UNIT INSTALLATION

Install as described in the installation manual supplied with the
outdoor unit.

REFRIGERANT PIPING WORK

For refrigerant piping of outdoor units, see the installation
manual attached to the outdoor unit.
Execute heat insulation work completely on both sides of
the gas piping and the liquid piping. Otherwise, a water
leakage can result sometimes.
Use insulation that can withstand temperatures of at least
120°C. Reinforce the insulation on the refrigerant piping
according to the installation environment. If the tempera-
ture in the wall reaches 30°C or the humidity RH80%, con-
densation may form on the surface of the insulation.
