(2) Fasten the indoor unit into place by tightening-up the special “B” bolts

and the M10 nuts. Make sure that unit is secure and will not shift back
and forth.

When installing the indoor unit in a semi-concealed orientation, make sure
to reinforce the insulation of the unit on all sides. Drops of water may fall
from the unit if it is not thoroughly insulated.

Glass wool insulate (10 to 20 mm
(3/8" to 3/4") thick)

••••• Install the drain pipe with downward gradient (1/50 to 1/100) and so

there are no rises or traps in the pipe.

••••• Use general hard polyvinyl chloride pipe (VP25) [outside diameter

38 mm (1-1/2")].

••••• During installation of the drain pipe, be careful to avoid applying

pressure to the drain port of the indoor unit.

••••• When the pipe is long, install supporters.

••••• Do not perform air bleeding.

••••• Always heat insulate (8 mm (5/16") or over thick) the indoor side of the

drain pipe.
