1 MAIN FEATURES
Comfort, low noise, and eciency in perfect harmony!
The new series of hydronic cassette units ACQVARIA, with ON/
OFF motor, consists of 5 models (10-20-40-50-60) for 2-pipe sys-
tems and 4 models (10-20-40-60) for 4-pipe systems.
The engineering of the unit makes it possible to develop up to
4,3 kW in the cooling mode in a standard 600x600 mm modular
suspended ceiling and over 9 kW in the 860x860 mm modulari-
ty, with exceptionally low noise levels in the phases for maintain-
ing interior comfort.
ACQVARIA leverages the entire Galletti, MYCOMFORT, EVO , and
TED microprocessor controller platform that incorporate sophis-
ticated adjustment logics based on air temperature, air humidi-
ty, and water temperature.
These benets translate into greater accuracy in achieving and
maintaining the desired comfort conditions through appropriate
modulation of the fan speed as well as the reduction of noise
emissions, which adapt to the actual thermal load.
The suspended ceiling unit houses all the components, heat ex-
change coil, fan drive assembly, and condensate collection and
drainage system. Its structure is designed for introducing fresh
air into the space, mixing it with recovered air, and distributing
the treated air from the cassette unit to adjacent rooms.
The design and colour, RAL9003 or RAL9010, of the air intake
and diusion louvre guarantee optimal integration into the sus-
pended ceiling panels. Easy access to the air lter for cleaning
operations.
The unit can be supplied complete with valves, including pres-
sure-independent balancing and control valves, the use of
which signicantly reduces commissioning time.

2 MAIN COMPONENTS
2.1 STRUCTURE
Made of galvanised steel sheet with internal polyurethane foam
coating and external closed-cell polyethylene foam to guaran-
tee heat and sound insulation. Fresh air can be introduced in-
to the room directly through the unit due to the provision of
connections for neutral or mixed introduction. Accessories are
available for connection to ducts. There are systems on the unit
for anchoring it to the ceiling. The electrical wiring is housed in
a containment box and is easily accessible from the side for easy
connection.
2.2 AIR FILTER
Honey-comb polypropylene washable air lter, easily removable for maintenance operations.
2.3 HEAT EXCHANGER
Copper pipe and high eciency aluminium ns secured to the
pipe by mechanical expansion. With at least two rows in the
models for 2-pipe systems, it is available in the 2+1 conguration
in the models for 4-pipe systems. The coil comes complete with
manual air vent valves. On request, valves can be connected to
the coil to regulate and balance the operation of the unit.
2.4 FAN DRIVE ASSEMBLY
Three-speed electrical motor, directly connected to a centrifu-
gal fan with backward-curving blades with prole optimised for
stable operation at all speeds.
2.5 CONDENSATE COLLECTION SYSTEM
Located under the heat exchanger, the main drip tray is made of
polystyrene and is inserted inside the proles optimised for the
distribution of air in the room. The supply is completed by the
auxiliary water drip tray for the collection of condensate from
the regulating valves.
2.6 CONDENSATE DISCHARGE SYSTEM
The condensate drainage pump, with built-in check valve, can
lift the condensate up to 0.9 m from the exit point from the unit.
The operation of the pump is controlled by a oat switch with
three levels of action that activate it and stop it during normal
operation. If the critical water level inside the main drip tray is
exceeded, an alarm signal closes the control valves, stopping the
ow of water inside the exchanger.
2.7 LOUVRE
It is square shaped for the intake and diusion of air in the space,
and it is made of ABS, colour RAL9003 or RAL9010. The air intake
louvre can be opened for access to the air lter. Air is diused in
the space through the 4 sides, each of which is equipped with an
adjustable n with suitable thermal insulation.

4 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: It is mandatory to install the 3-way (or 2-way)
valve accessory in order to avoid the circulation of cold
water in the exchanger if the unit is not operated for
long periods of time, with the fan o. Install the auxiliary
water drip tray, provided together with the base unit, in
order to prevent valve kits from dripping.
For each unit an (IL) switch should be mounted on the power
supply, with opening contacts at a distance of at least 3 mm
and a suitable protection fuse (F) .
WARNING: before carrying out any operation, check that
the voltage and frequency of the unit correspond exactly
to those of the main power supply.
WARNING: Install the unit, circuit breaker (IL) and/or any re-
mote controls in a place out of reach of persons who may be
taking a bath or shower.
WARNING: keep the unit's grille in its original packaging
until nal assembly.
RECOMMENDED: to ensure optimal comfort (homoge-
neous air temperature in the room), it is recommended not
to exceed a heat exchanger water inlet temperature of 55 °C.
WARNING: during a shutdown for installation, in the event
of a connection to a fresh air intake or an ambient tempera-
ture close to 0 °C, there is a risk of the pipes freezing. Provide
drainage for the water circuit.
4.1 INSTALLATION REQUIREMENTS
The fan coils should be installed in a position where the room
can be heated or cooled evenly, on ceilings able to support their
weight. Store the unit in its packaging until you are ready to in-
stall it.
For installation and use of accessories, please refer to the relative
technical sheets.
Install any remote control panel in an easily accessible position
allowing the user to set the functions while ensuring an accurate
reading of the ambient temperature, if provided.
Avoid therefore:
 positions directly exposed to sunlight;
 positions exposed to direct currents of warm or cold air
 placing obstacles that impede an accurate temperature
reading
NB: The water sensor, where present, must be mounted in
the appropriate trap on the valve kit, on the INLET pipe.
1 Water sensor holder
1
 If a valve kit other than the one suggested is used, it is neces-
sary to install the sensor on the INLET pipe, by means of the
special copper socket lled with conductive paste.
 Lastly, the sensor must be properly isolated to ensure that it
reads the water temperature correctly.
NB: The air and humidity sensors, where present, must be at-
tached in the appropriate section located in the intake area
of the base unit.
1 Sensor retainer
1
Make the plumbing connections to the heat exchanger and,
where the cooling function is to be used, to the condensate
drainage outlet.
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:
 20-14 = 6 °C in order to avoid condensation on a fancoil
equipped with a valve.

If the valves are not installed, there could be abundant con-
densation, especially if the unit is not operated for long pe-
riods of time.
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.

To optimise performance, it is advisable to make the following
connections on the exchanger:
 Unit outlet: connection below.
 Unit return: connection above.
WARNING: While making the connections, hold the water
connections of the unit tightly in place with a hexagonal
wrench or make sure that they do not rotate, in order to pre-
vent the pipes inside the unit from being damaged.
 Carefully insulate the inlet and outlet water pipes as well as
the devices installed in the network (on/o valves…). Use a
material that is suitable for the operating conditions and wa-
ter temperature.
 Bleed air from the exchanger by means of the air vent valves
located next to the water connections of the coil. Depending
on the installation, it may be necessary to place other vent
valves on the hydraulic system.
4.1.3.1 Condensate drain connection
Connect a rigid PVC pipe to the end of the hose and secure it
with a clamp
Correctly insulate the pipe with polyethylene foam.
 Be careful of the risk of freezing in winter in suspended ceil-
ings.
 If necessary, the condensate pipe can be routed immediately
after the unit's outlet. Maximum height: 900 mm (FIGURE 1).
 Make sure that the drainpipe has a slight slope in the direc-
tion of ow and that it does not form a siphon (FIGURE 1).
 The piping must have several supports (FIGURE 2).
 Do not install an air vent (FIGURE 3) in the wrong position.
