3.3 Handling
The units are delivered already screwed to pallets
made to fi t the sizes of the casing.
KSDR ECOWATT
®
air handling units can be han-
dled by pallet truck, by forklift truck or by crane.
Handling machines will be adapted to the raising
load and conditions.
The lifting will be preformed in all cases from the
base of the device attached to a pallet. The centre
of gravity is located at the centre of the unit.
The device must be handled with care and only in a
horizontal position.
3.4 Location and Attachment
The KSDR ECOWATT
®
AHU must be placed on a horizontal and smooth surface that is able to bear the
load. The EXD and EXG models are intended for indoor or outdoor installation.
In all cases, provide for any ducts, wiring accessories, anti-vibration and anti-freezing protection equipment
of the water coil. In areas with a high snowfall, additional protection should be considered. It is important to
provide for enough space so that the panels can be opened, started p and maintained (fi lter, fan, coils/electric
heaters). No not place the unit against a wall in order to prevent the transmission of structure-borne noise.
The casing must be attached to a completely fl at support by the side holes provided for this purpose. As-
sembly operations should be performed on anti-vibration supports or plates and the wiring should involve
soft spool pieces.
Provide the following necessary clearances for maintenance operations:
4. HYDRAULIC CONNECTION
4.1 Wiring of water coils
The hydraulic features of the unit are particular to your installation and
are determined by IT selection: Loss of head in relation to the water/Flow
of water. Refer to the selection in order to dimension the network, acces-
sories and pump.
The connection of the piping to the coil must not impose any mechanical,
vibration or thermal (dilatation) constraints.
Coils are delivered already threaded at the ends.
During tightening on the threading of the coil, keep the piping in reverse,
for instance using a pin spanner to stop the pipes from becoming dam-
aged through twisting.
Respect the water input and output direction indicated on the label glued
to the coil panel.
