number,...) enabling you to identify it. Each unit has
an identification plate marked with an identification
number to be given in all correspondence.

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.

Handling
Caution : The unit must be handled with care. 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.
Putting the unit in place
The unit should be installed inside the false ceilling.
If the unit isn't ducted to the inlet, make sure to
respect a distance between the wall and the rear of
the unit (X=250 mm mini) (fig.3).
The unit should be fixed to the ceiling using
threaded rods (not supplied), use the 4 fixation
holes with elastic dampers (accessory) (fig.1-9).
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.
Aeraulic connections
Follow the recommendations relating to the aeraulic
balancing of the units and sealing possibilities of Y
model's discharge spigots, according to sizes
(fig.4).
Recommanded air flow for outlet :
- ∅ 200mm
- ∅ 250mm
Caution : Spigots on H or U models must not be
blocked, neither on the discharge nor on the intake
sides.
hydraulic connections
The coils are equipped with monobloc "female"
threaded double hydraulic connections (fig.6a), air
vent and drain.
To fit a control valve with a flat seal, a CIAT
connector is necessary (fig.6b). The CIAT hydraulic
connectors are equipped with a flange to maintain
the gasket in position during tightening. The table
(fig.6d) gives the CIAT recommendation concerning
the joints.
Installation :
In order not to deteriorate this connector or the
CIAT valve, do not apply a torque superior to 3.5
daN.m. Respect the valve assembly direction.
On these CIAT valves, the circulation must occur
from A → AB (A being connected on the coil side
and AB on the hydraulic pipework). The maximal
admissible differential pressure on our valves (open
or closed) is 100 kPa. CIAT recommends not to
overpass 60 kPa.
