5. Precautions on installation
NOTICE
If drain holes of the outdoor unit are covered by
a mounting base or by floor surface, raise the
unit in order to provide a free space of more
than 130mm under the outdoor unit.
5.1
Foundation work
Check the strength and level of the installation
ground so that the unit will not cause any operating
vibration or noise after installation.
In accordance with the foundation drawing in the
figure, fix the unit securely by means of the foundation
bolts. (Prepare four sets of M12 foundation bolts, nuts
and washers each which are available on the market.)
It is best to screw in the foundation bolts until their
length are 20mm from the foundation surface.
Fix the outdoor unit to the foundation bolts using nuts
with resin washers(1) as shown in the figure.
If the coating on the fastening area is stripped off, the
nuts rust easily.
