Installation Procedure
4. Installing the indoor unit
(1) Lift unit so that suspension bolts pass through suspension fittings at
the sides (four places),and slide the unit back.
(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.
For half-concealed installation
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.
CAUTION
In order to check the drainage, be sure to use a level during installation of
the indoor unit. If the installation site of the indoor unit is not level, water
leakage may occur.
5. Installing the coupler heat insulation
After checking for gas leaks, insulate by wrapping insulation around the two parts (large and
small) of the indoor unit coupling, using the coupler heat insulation. After installling the coupler
heat insulation, wrap both ends with vinyl tape so that there is no gap. Secure both ends ofthe
heat insulation material using nylon fasteners.
