Installation information
For piggyback units, where the top and bottom units are supplied separately,
the units must be secured to each other on site.
The manufacturer makes provisions for the connections to be made with self-
tapping screws. The required number of self-tapping screws are supplied with
the air-conditioning unit.
The top and bottom unit can only be screwed together after the individual
cubes of the top and bottom units have been assembled.
In some cases, permanent elastic sealing strips or plastic sealing strips must
be applied before positioning the top onto the bottom unit (see page 8/9).
To simplify the assembly, the manufacturer provides holes in the cube frame
and frame capping of the bottom unit at the intended joints.
The holes in the frame capping must be sealed with the supplied plastic plugs
after the top and bottom unit have been screwed together.
In some cases, plastic sealing sections must also be applied (see page 9).
The areas intended to be joined are identified by the manufacturer with a label
on the covering panels on the external side of the unit ("Remove cover panel
for assembly of unit").
The label can be removed from the panel without leaving any marks.
The units are supplied in assembled condition. They may be demounted before
transportation and be reassembled on site.
The frame sections of the demountable version are separated in the centre
and bolted together with a steel plate.
For demounting, the internal frame cover must be removed and reassembled
after assembly of the cubes.
