1 MAIN FEATURES
PERFORMANCE AND COMPACTNESS IN RECESSED CEILING INSTALLATIONS
The ducted units DUCTIMAX was designed for conditioning en-
vironments where it is required the installation of units in medi-
um head performance and reduced overall dimensions.
The range covers an air ow rate from 300 to 1200 m³/h distrib-
uted over 12 models. The heat exchanger allows the use of DUC-
TIMAX in the most dierent conditions.
The bearing structure in fact accommodates a heat exchanger
of 3 or 4 rows to which it is possible to combine an additional
heat exchanger of 1 or 2 raws for exceptional performance even
at low temperature dierentials.
Heat exchanger can be optimized for centralized applications
such as district cooling. DUCTIMAX was designed to ceiling hori-
zontal installation.
The main condensate drip tray is situated inside the structure of
the unit and is at a positive pressure relative to the drain outlet
to facilitate condensate drainage.
A wide range of wall-mounted controllers is available, including
controllers of an electromechanical type and microprocessor
controllers with display.
The use of MYCOMFORT BASE, MYCOMFORT MEDIUM AND MY-
COMFORT LARGE or EVO allows connectivity of DUCTIMAX to
GARDA. Electric heating elements complete with safety devices
are available to integrate the hydronic operation.
The action of the G3 air lter can be combined with an air ioni-
sation system.
2 MAIN COMPONENTS
STRUCTURE
Realized in galvanized steel sheet, thermally and acoustically
insulated by self-extinguishing panels class 1.
Height reduced to facilitate installation in a horizontal position,
in false ceilings.
The bearing structure contains the tank for collecting and dis-
charging condensate.
ELECTRIC MOTOR
Single-phase asynchronous multi-speed electric motor with permanently connected capacitor and thermal protector, mounted on
vibration-damping supports.
AIR FILTER
Washable air lter, made of acrylic bre, ltration class G2 or G3, applied on the air intake; may be pulled out from below.
AIR INTAKE
Air intake from the front or bottom of the unit, according to system requirements. See gure 15.2p.48 and 15.3p.48.
HEAT EXCHANGER
High eciency 3 or 4 rows heat exchanger made of copper
tube and alluminium ns secured to the tubes by mechanical
expansion.
It is tted with brass manifold and an air valve.The heat
exchanger, usually with left hand water connections can be
turned by 180°.
Available on request high eciency heat exchanger optimized
for district cooling application.
FANS
Double suction centrifugal fans made with ABS or aluminium, with statically and dynamically balanced forward-curving blades,
directly coupled to the electric motor.

TECHNICAL MANUAL6
3 INSTALLATION
WARNING: unit installation and start-up must be entrusted
to competent personnel and performed in a workmanlike
manner, in accordance with current regulations.
WARNING: Install the ducted unit, the line switch (IL) and/or
all remote controls in a position out of the reach of persons
who are in the bathroom or in the shower.
ATTENZIONE: For safety reason, do not introduce your n-
gers or other pointed objects in the air outlet grilles.
DANGER: The unit may be used by children of at least 8
years of age and by persons with reduced physical, sen-
sory, or mental capabilities, or who lack experience or the
necessary knowledge, provided that they are supervised or
after they have received instructions relating to the safe use
of the unit and understand the inherent dangers. Children
must not play with the unit. Cleaning and maintenance to
be carried out by the user must not be performed by unsu-
pervised children.
IMPORTANT: It is advisable to install any accessories on
the standard unit prior to positioning the latter, making
reference to the technical sheets. The air intake and outlet
have a rectangular cross-section, with pre-cut holes for fas-
tening the available accessories. To make connection using
rectangular ducts it is recommended to use accessories RDD
or RDCD, which can be tted respectively on the intake or
outlet section.
NOTE: to install ducts on both the inlet and outlet sides, you will
need 1 RD accessory (intake) and 1 RDC accessory (outlet).
WARNING: If you wish to make the connections using ex-
ible circular ducts (ø 200), it will be necessary to use acces-
sories PMA or PMAC, which can be tted respectively on the
intake or outlet section.
NOTE: to install exible ducts (Ø 200), on both the inlet and out-
let sides, you will need 1 PMA accessory (intake) and 1 PMAC ac-
cessory (outlet).
WARNING: with MAF90 or MAFO90 is possible to have
frontal air intake to better adapt it to system requirements.
For installation follow the instructions in gure 15.3p.48.
The exchanger connections can be switched over to the oppo-
site side by carrying out the following steps:
Ū remove the upper closing panel.
Ū remove the collecting condensate tray.
Ū remove the heat exchanger module by taking out the fas-
tening screws (2 per side).
Ū turn the heat exchanger by 180° (on the vertical axis) and
screw it back into the unit again.
Ū reassemble the tray and the upper closing panel.
3.1 INSTALLATION REQUIREMENTS
Some rules to follow
Ū Vent air from the exchanger while the pumps are o. For this
purpose use the air vent valves situated next to the exchang-
er connections.
Ū All ducts, especially the outlet ducts, must be insulated with
anti-condensation material.
Ū An inspection panel must be provided in proximity to the
unit to enable maintenance and cleaning operations.
Ū Install the control panel on the wall; choose an accessible
position from where functions may be easily set and which is
suitable for taking temperature readings, where applicable.
Avoid positions directly exposed to sunlight or direct cur-
rents of hot or cold air and make sure there are no obstacles
which may preclude a correct temperature reading.
WARNING:
In normal operation, particularly with the fan at minimum
speed and ambient air with high relative humidity, conden-
sation may form on the air outlet and on some external parts
of the unit.
To avoid such issues while always remaining within the oper-
ating limits envisaged for the unit, it is necessary to limit the
inlet temperature of the water inside the heat exchanger. In
particular, the dierence between the air dew point (TA,DP)
and the inlet water temperature (TW) must NOT exceed 14
°C, according to the following relationship: TW>TA,DP-14
°C
Example: in the case of ambient air at 25 ° C with 75% rela-
tive humidity, the dew point temperature is about 20 ° C and
therefore the inlet temperature of the water in the battery
must be greater then:
Ū 20-14 = 6 °C in order to avoid condensation on a fancoil
equipped with a valve.
Ū 20-12 = 8 °C If the valve kit accessory can not be installed.

In the event the indoor unit is stopped for a prolonged peri-
od, with the fan stopped and circulation of cold water in the
heat exchanger, condensation may also form on the unit’s
exterior. In this case it is advisable to install the 3-way (or
2-way) valve accessory in order to stop the ow of water in
the coil when the fan is stopped.
During wintertime periods of quiescence, drain water from the
system, to prevent ice from forming. If anti-freeze solutions are
used, check for their freezing point using the table below.

3.2 ASSEMBLY OF UNITS
Mounting the unit
Insert the vibration dampers provided in the 4 slots indicated for
ceiling installation
Fasten the base unit to the ceiling or wall using the 4 slots
provided.
Ū It is recommended to use 8MA threaded bars plus screw an-
chors of adequate capacity to bear the weight of the unit,
and to prepare the positioning of the unit using 3 8MA nuts
(2 in the lower part, 1 in the upper part as shown in gure
3.1  p. 7 ) and two M8 oversized washers with a diam-
eter of 24 mm for each bar, so that the rubber anti-vibra-
tion mounts cannot deform or come out of the slot. Before
tightening the lock nut, adjust the main nut so as to assure
that the unit is properly inclined so as to facilitate condesate
drainage (gure 3.2  p. 7). To obtain the proper inclina-
tion, tilt the unit so that the intake side is slightly lower (ap-
proximately 10 mm) than the outlet side. Make the plumbing
connections to the heat exchanger and, where the cooling
function is to be used, to the condensate drainage outlet.
Use one of the two tray drain outlets, which can be seen on
the outside of the unit side panels.
Ū To connect the unit to the drainage line, use a exible rub-
ber hose and secure it to the pre-selected drain pipe (ø 3/8'')
using a metal clamp (use the drain outlet situated on the
plumbing connection side).
