4 - INSTALLATION Unit/Frame/Plenum
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.
•
In the case of models larger than CW45, and for reasons of convenience, the
horizontal shoulder brackets (with oblong holes) may be removed from the
bottom of the unit once the unit is placed in its permanent location. See photo.
•
The cabinet frame must rest fully on its contact surface.
Units fitted with a support base:
•
The floor must be as flat as possible,
•
Level the unit by adjusting the legs on the support base.
•
A seal must be placed between the unit and bed of the frame.
First adjust using the screws at the predefined heights.
Then adjust up to ± 30 mm.
Units supplied 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.
5 - CONNECTIONS
5-1 Hydraulic connection
The hydraulic pipes must be routed through the designated plate on OVER models (supply air at top) or directly
through the bottom of the unit on UNDER models (supply air at bottom).
1. Remove the precut foam panel,
2. Drill the external panel,
3. Drill the corresponding holes in the panel then put it back in place before routing the
pipes.
Fit a trap: H = 100 mm
If the humidifier option is selected: the drained water will not flow into the unit's drain pan.
To have a single drain for both, connect the humidifier drain after the unit's drain pan.
Warning : The operating pressure on the chilled or hot water network must not exceed 8 bar.
