4.3 Assembling the
air/water heat exchanger
The air/water heat exchanger can be mounted on the
outer walls or the door of the enclosure.
For this purpose, the appropriate enclosure panel
or door must be cut out using the supplied drilling
template.
4.3.1 Preparing the mounting cut-out
Stick the supplied drilling template onto the side
panel or door of the enclosure using adhesive
tape. The heat exchanger is suitable for both exter-
nal and internal mounting.
There are dimensioning lines on the drilling template
to suit the installation type for your air/water heat
exchanger.
Make the cut-outs including the line width as per
the drilling template. Deburr the cut-outs.

Risk of injury!
Carefully deburr all cut-outs to prevent
injuries caused by sharp edges.
Note:
In order to achieve a permanent seal
between the air/water heat exchanger and
the enclosure, the mounting surface should
be reinforced or supported if necessary.
Note:
For both types of mounting (internal and
external), use the assembly parts supplied
in the pack.
Note:
For models 3373.XXX, 3374.XXX and
3375.XXX, steps 4 and 5 are additionally
required.
