DESCRIPTION OF THE UNIT

The EXCI series conditioners are constituted by an indoor air
treatment unit and by an outdoor unit to be connected to each
other by means or refrigeration and electrical lines.
They are available in three sizes with different capacities in
heat-pump version able to perform both summer cooling and
the winter heating.
All the EXCI units have an "A" class energy effi ciency in cooling
mode and "A" class energy effi ciency in heating mode.
The inverter device permits great energy saving and the
optimisation of the environmental conditions, the required
temperature is reached more quickly than systems without and
inverter.

DESCRIPTION OF COMPONENTS

The indoor unit is made of galvanised steel sheet. At the back
there are holes to fi x the equipment to the wall, at the front there
is a steel sheet panel enclosing the fan unit. The trays for the
collection of the condensate are fi tted with special drainage
features, it is possible to attach the channels for the renewal of
the air in the environment and/or for delivery to a next door
room, to the unit.
The unit contains:
– the heat exchanger coil with copper pipes and turbulenced
type fi ns made of aluminium locked in place by means of the
mechanical expansion of the pipes;
– the fan unit on anti-vibration mountings with double-suction
centrifugal fans, coupled directly to a three-speed motor with
thermal protection.
The fact that the tray and inspectable fan volutes may be removed
(only by adequately skilled technicians) allows the internal
components to be cleaned thoroughly, which is particularly
important for installations in crowded areas or areas requiring

The units are characterised by very quiet operation and great
reliability.
The indoor unit has a maintenance charge (nitrogen).
The control device (accessory TL2I) consists of an infra-red
remote control and a wall receiver, it provides full control
functions.
The EXCI series conditioners are able to meet climate-control
requirements in all environments thanks to the versatility of the
indoor units made for horizontal or upright installation, with
channels (the series is available with a large range of plenum
chambers and dedicated fi ttings for every size) or with casings
(accessories).
high hygiene standards.
The units are confi gured in the factory in such a way as to have
the rated air fl ow and null residual static pressure. To get the
maximum useful static pressure for the channelling again with
the rated air fl ow make the connections as shown in the
following wiring diagrams;
–the microprocessor type control unit with dip switches to be set
during installation in accordance with the confi guration of the
machine and the accessories;
–fi ltering unit that can be easily removed in material that can be
regenerated can be cleaned by washing;
–intake temperature probe.
–defrosting device (only for the versions with heat pumps) is
controlled by means of a probe on the interior coil and the
environment air probe that are controlled by the electronic card
which turns the defrosting circuit on and off. It permits the
proper functioning of the device with high yields down to an
outside temperature of -10°C.
