12.4 Raised floor stand
The floor stand is used to adjust the height of the A/C unit to the existing raised floor and consists of an encircling
rectangular profile of welded steel. Before the positioning of the stand the adjustable threaded supports must be
screwed in the raised floor stand. The floor stands exists in 6 different heights which can be fine adjusted by the
threaded supports. The cut-out in the raised floor must be designed 10 mm larger at each side than the fan unit.
Minimum distances and mounting instructions
- Observe that the fan unit must be decoupled from
the surrounding floor plates by damping insertions
and that mafund plates are laid under the floor sup-
ports.
- The raised floor cutting (notch) should at least be 15°
and must not have any contact to the fan unit, which
could result in bone-conduction.
- If the floor stand is placed near a wall, a minimum
distance of 50 mm should be respected. The gap
between wall and fan unit should be closed by tin
stripes.
- The dimensions of the openings in the raised floor
must be 10 mm larger than the fan unit. The joint must
be closed by customers with a continuous seal.
- A concrete foundation is recommended in the area
of the raised floor supports.
- The raised floor supports have to be installed on vi-
bration dampening material (do not screw down the
supports!).
- Prior to installation of the A/C unit, the fan unit must
be installed 7 mm higher than the raised floor plates,
as the mafund plates are compressed by the weight
of the A/C unit.

Positioning of the fan unit on the floor stand
When positioning the fan unit on the floor stand, it must be brought precisely into the correct position above the floor
stand from the front (under no circumstances diagonally). Hereby use mounting aids to bring in the unit and secure
these by fixing belts. We recommend further to lay in advance at least two securing instruments (e. g. square steel
bars) on the stand to avoid a slip-off.
When the unit is in the right position the securing aids can be taken away and the fan unit can be set down. Now the
mounting aids can be pulled away under the unit.
