4. INSTALLING THE INDOOR UNIT
• For left piping and left rear piping, preset the end of
the pipe to the dimensions shown in Fig. 14 from the
mark on the wall hook bracket and form the connec-
tion pipe.
• Bend the connection piping at a bend radius of at least
100 mm and position it no more than 50 mm from the
wall.
[Installing the indoor unit]
• Piping work can be made easier by laying out, shap-
ing, and temporarily fastening the connection pipe,
drain hose, and connection cord as shown in Fig. 16
beforehand.
[Heat & Cool model (Reverse cycle)]
(3) Remove the cord clamp.
(4) Process the end of the connection cords to the
dimensions shown in Fig. 19.
(5) Connect the end of the connection cord fully into the
terminal block .
• When extending the drain hose at the indoor unit,
install the acces-sory drain insulation.
• Place the indoor unit drain hose behind the piping.

2. INDOOR UNIT WIRING
(1) Match the terminal block numbers
and connection cord colors with
those of the outdoor unit.
Erroneous wiring may cause burning
of the electric parts.
(2) Connect the connection cords firmly
to the terminal block. Imperfect
installation may cause a fire.
(3) Always fasten the outside covering
of the connection cord with the cord
clamp. (If the insulator is chafed,
electric leakage may occur.)
(4) Always connect the ground wire.
(1) Remove the intake grille.
(2) Remove the terminal cover. (Fig. 18)
