3.4. Positioning by hand
When moving the unit elements into position, never apply force on the heat exchanger
connections, panelling or other mounted parts. Always move the unit by its base frame. Never
attempt to move the unit elements using a hammer or other heavy implement.
4. Installation of unit
4.1. Foundation / base frame
As the unit must be accessible for maintenance, keep an area of minimum the width of the
unit + 300 mm free on all sides to facilitate the exchange of built-in components. The
foundation must meet the relevant static and sound propagation requirements and must
feature a proper drain for water. It must be level and smooth. The resonance frequency of the
support structure must be distinctly different from the excitation frequency of the rotating
machine components (fan, motor, pumps, etc.).
Suitable foundations: Solid concrete foundation, strip foundation or steel girder construction.
When using strip foundation of steel girders, ensure that the unit elements with a base frame
(base profile) are positioned properly on the support structure. The rigidity of steel girder
constructions must be suitable for the size and weight of the unit. For standard units without
feet, the clearance from the ground must not exceed 150 mm.
