RECAUTIONS ON INSTALLATION
Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after
installation.
Prepare 4 sets of M8 or M10 foundation bolts, nuts and washers
each (field supply).
Fix the unit securely by means of the foundation bolts in
accordance with the foundation drawing.
It is best to screw in the foundation bolts until their length are
20 mm from the foundation surface.
Install the unit on a base that can assure a proper drainage in
order to avoid ice accumulation.
A drain channel can be foreseen under the unit. Be sure that
drain water in this drain channel does not freeze causing
blockage by ice accumulation.
Avoid drain water flowing over the footpath, so that in case of
ambient freezing temperatures the footpath does not become
slippery.
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 150 mm under the
outdoor unit.
