It is very important to determine a suitable place to hang flat units that attached to the ceiling. Do not hang such units
above the stairs or high above, where it will not be possible to reach it without using special equipment. If the unit is hidden
behind the suspended ceiling, the inspection hole (if any) must not be smaller than dimensions of the unit, or the inspection
opening (if any) should not be smaller than the size of the unit, or the ceiling must be installed in such a way that it can be
easily dismantled without damaging their structures.
•
It is necessary to install additional service areas for units installed high above, which would allow
to work safely during technical maintenance (e.g., during filter replacement) or repair.
•
When choosing a place to place or hang the unit, keep in mind that preventive maintenance
should be performed at least twice a year, and sometimes more often; therefore, the user or the
person responsible for the maintenance of the unit must reach it as safe and simple as possible.
3.3. Connection of Sections
Larger units of some models are assembled from separate sections (see section “Unit components”) in order to transport
them easier or to transfer them through the narrow openings of the building structures. Such units are usually assembled at
their final installation site. Depending on whether the unit was ordered without any mounting frame, with a factory-fitted
mounting frame or the one purchased separately, mounting of the sections slightly differs. Sections of the units without a
mounting frame should be simply interconnected. Sections of the units with factory-made mounting frames that are de-
signed for every section separately should be additionally tightened through the designated holes in the mounting frame
(first, screw the bolts at the internal connections of the sections and only then fasten the mounting frame). If the units are
mounted on a separately ordered mounting frame (see Fig. 9), their sections should be assembled and fastened together by
placing them on the mounting frame and then attaching self-tapping screws to it.
