ECEPTION
The unit is supplied in labelled cardboard packaging
with all the unit’s characteristics (type, model, SO
number,...) enabling you to identify it. Each unit has
an identification plate marked with an identification
number to be given in all correspondence.
When the packages are received, the inspection of
the condition of the goods at arrival is the recipient’s
entire responsibility :
•
For shortages, the customer must mention the
exact number of packages received.
•
In the event of defects on the units, the customer
must describe the damage observed on the receipt
in the presence of the delivery person, and only
sign the receipt after having done this.
IMPORTANT : These remarks, in compliance with
article 105 of the French trade code, must be
confirmed by registered letter to the transport
operator within 3 working days. The terms
”reservations” and ”subject to unpacking” are not
valid. The customer must unpack the goods in the
presence of the delivery person. Specific
reservations at delivery are required.
H
ANDLING
Caution : The unit must be handled with care. Do
not press on the diffuser nozzles as they may be
damaged.
With shocks there is a risk of twisting the frame and
damaging the fan-motor assembly. If possible the
unit should be lifted using the fixation holes. If this
lifting means cannot be used, the operation can be
carried out using a fork-lift truck after removing the
distribution panel.
P
UTTING THE UNIT IN PLACE
The unit should be installed inside the false-ceiling
with the intake next to a wall (fig.6), and never in
the middle of the room. Air diffusion should be
directed on the length of the room in front of the
window, and should not be perturbated by a beam
or lightings.
The unit should be fixed to the ceiling using
threaded rods (not supplied), use the 4 fixation
holes with elastic dampers (accessory) (fig.3) that
give the best weight repartition. That means, those
situated to 213.5 mm of each sides. Check the unit
with a spirit level.
If a control with wall thermostat is used, do not
expose it to the sun, behind a door, nor above an
apparatus discharging heat, but rather on an interior
wall to 150 cm height.
O
RIENTATION OF THE AIR JET
The air diffusion nozzles are orientables with a
supplied key (fig.5). Depending upon the
configuration of the room, to avoid the air jet to
hnock against the window and to generate
draughts, the blowing can be enlarged, and the
span reduced :
1 - Insert the key on an incline between two fins of
the nozzle.
2 - Turn the key to orientate the nozzle to the
desired angle.
HYDRAULIC CONNECTIONS
The coils are equipped with monobloc "female"
threaded double hydraulic connections (fig.10a), air
vent and drain.
To fit a control valve with a flat seal, a CIAT
connector is necessary (fig.10b). The CIAT
hydraulic connectors are equipped with a flange to
maintain the gasket in position during tightening.
The table fig.10 gives the CIAT recommendation
concerning the joints.
To avoid any risk of condensation when using
chilled water, it will be necessary to insulate the
pipework, ensuring that it is vapour sealed.
For use with 2-pipe/2-wire coil, we advise installers
against the use of PER piping for connections. In
case of overheating of the electric coil, an important
rise of the temperature is possible. This one can
deteriorate characteristics of the PER up to the
blow-out. We advise to connect the coil by means
of a flexible with a stainless stell treillis fence (or
equivalent).
