• Before installing the indoor unit, prepare opening
960mm x 520mm on ceiling, and 868mm x 152mm
on wall and arrange drain pipe, refrigerant pipe and
connecting cord in their installation positions.
• For
fi
nishing of opening on ceiling and wall arrange
with builder in detail.

CAUTION
!
• Install the indoor unit in a straight level. If the
indoor unit is inclined, water may leak.
• If space between bottom surfaces of indoor
unit and ceiling is not correct, there may be a
gap between grille and ceiling surface, with
consequent leakage of condensed water.
• If gluing of drain hose and PVC pipe is too weak,
water leakage may occur.
• If checking of drainage is omitted, water leakage may
occur.
• If drain pump test run is left set to TEST, drain pump
may malfunction.
CAUTION
CAUTION

• If space between bottom surfaces of indoor
unit and ceiling is not correct, there may be a
gap between grille and ceiling surface, with
consequent dropping of condensed water.
• Jagged edge will cause leakage.
• Point the side to be trimmed downwards during
