5.1 - Setting the unit in place
-
The unit must be placed on a flat, smooth surface which is as level as possible (ratio of approx. one to one thousand).
-
If the supply air is conveyed through a raised floor, the seal between the unit and the floor must be tight.
-
The unit need not be anchored to the floor if it is operated under normal conditions.
-
Provide sufficient space for maintenance around the unit.
-
The cabinet frame must rest fully on its contact surface.
■
Units fitted with a support base
-
The floor must be as flat as possible,
-
A seal must be placed between the unit and bed of the frame.
-
Level the unit by adjusting the legs on the support base, (see the drawing of the base
supplied with the unit)
5.2 - Units equipped with a plenum:
■
Supply/extraction plenum
Proposed when air is to be distributed directly into a space. It is mounted on top of the cabinet and
features double-deflection grilles to allow the direction of the air stream to be adjusted.
The plenum may also be used mounted at the bottom to carry air directly from a space back to the air
handling system.
The plenum is secured from the inside at the 4 corners. To secure it, the diffusion grille on the front panel
must therefore be removed.
