Fixing method of the unit
Make sure that the floor is strong enough to bear the unit.
1) Level the indoor unit with the leveling screws
(accessory part). If the floor is too uneven to level
the unit, place the unit on a flat and level base.
2) If the unit is in danger of falling over, either fasten to
the wall using the holes provided, or fasten to the
floor with a field supplied floor fastener.
6. OUTDOOR UNIT INSTALLATION
Install as described in the installation manual supplied with the
outdoor unit.
7. 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.
