(by
separating
the
scroll
set

This
technology
is
interesting
for
multiple

must
be
handle
by
elevator
Units
size

and
5:
Units
have
4
attachment
lugs
for
handling
(situated
on
4
frame
angles).
During
handling
of
condensing
units
with
a
crane,
lifting
hooks
will
be
fix
to
the
4

SPECIFIC
INSTALLATION
RECOMMENDATIONS
The
unit
must
be
put
and
fixed
to
a
ground
plan
supporting
the
weight
of
the
unit
(4
points
of
fixation
are
foreseen).
Any
other
mounting
will
have
to
be
the
object
of
a
study
of
structure
adapted
to
the
frame
of
the
unit.
