The air conditioning units in the FTA
range have been designed for civil,
commercial and hotel use, for small
and medium sized rooms. The units are
designed to guarantee high head levels
and can be installed either vertically
or horizontally, thereby offering
greater versatility. Thanks to this type
of unit, several rooms can be served
via a distribution plenum. The units of
this range are characterised by their
compact size, low noise levels, and the
wide choice of accessories.
STRUCTURE
The load-bearing structure is made of
galvanised steel sandwich panels with
polyurethane insulation (density 40kg/
m³), 15 mm thick. The suction and
supply panels are fitted with flanges for
connecting any air pipes or accessories
envisaged. Special brackets supplied
with the unit make it easier to fix it to
the wall.
The condensate drip tray, in galvanised
steel, has a threaded drain connection
on both sides and can be used whether
the unit is installed horizontally or
vertically.
ELECTRIC FAN UNIT
Consist ing of high performance
centrifugal fans with double intake
and forward blades. The multispeed
electric motor, for which three speeds
can be selected from the control panel
(optional), is directly connected to the
fans.
HEAT EXCHANGE COIL
In copper piping and aluminium finning
blocked by the mechanical expansion of
the pipes.
Threaded pipe couplings for the
hydraulic connections and air drain
valve are supplied. Two versions are also
available with a direct expansion coil in
copper piping with aluminium finning
blocked by the mechanical expansion of
the pipes (3 or 4 rows).
FILTERING
The air is filtered through synthetic
filters, 50mm thick, in efficiency class
G4 (in compliance with standard EN
779), positioned at the suction point.
The filters can be easily accessed for
maintenance and cleaning. For the
VRFxF accessory, the air is filtered
through soft pocket filters with a
filtering degree of F6. For higher
filtering degrees, contact our Technical/
Sales Office.

Compatibility of accessories
The diagrams showing the various ways of combining the accessories with the standard units can be found below. The selection of a suction/supply accessory module precludes the choice of other accessories in the vertical direction, but not in the horizontal direction.
For example: if the “SAPxF” accessory is used at the suction point, it is not compatible with accessory “S2ZxF” but can be used with accessory “SSLxF” or “FTPxF”. The diagrams show a horizontal and vertical configuration of the unit respectively.
The diagrams may not fully represent all the available combinations: you are, however, advised to respect the rules laid out and to contact the Fast Technical/Sales Office if necessary.
HORIZONTAL
NB:- Warning: for safety reasons, you are advised to avoid positioning the FTFxF “Pocket filters” module near the PBExF module.- Warning: when using the PBExF accessory, the unit delivery must not fall below 60% of normal envisaged delivery.- The VRFxF accessory is fitted with an electronic rotation speed variator.- The M3SxF accessory must be combined with the VRFxF accessory.- The VRFxF accessory can be selected even if it is not combined with the M3SxF accessory.

Characteristic ventilation curves
The following diagrams show the
effective static supply/pressure curves
(at the inlet) of the FTA units.
These curves refer to units with a 3-row
coil and a 0% obstruction level of the G4
filter.
For units configured or differently,
or with different accessories, it is
necessary to reduce the effective static
pressure with the values of the pressure
drops of the added components.
The values of these pressure drops can
be obtained from the tables beneath
the charts.

Pressure drops in the filters, due to dirt
The charts to determine the pressure
drops with different filter dirt levels are
shown below. From the left-hand chart
(showing the air flow rate - m³/h - on
the x co-ordinate), locate the flow rate
in question then go up until you intersect
the straight line corresponding to the
unit size. At this point, by tracing a
straight line parallel to the x co-ordinate
axis, you will intersect one of the three
curves on the right-hand chart, each
showing the degree of obstruction of the
filter, as below:
curve 1: clean filter
curve 2: filter 25% clogged
curve 3: filter 50% clogged
To determine the corresponding value of
the filter pressure drop, trace a straight
line as far as the x co-ordinate axis.

• the load must be suitably protected.
CHECKS UPON RECEIPT
Upon receipt of the unit, an initial visual
check must be made for any damage re-
sulting from transportation. If damage is
discovered, this must be highlighted on
the accompanying travel document.
The essential indications for the correct
installation of the equipment are given
below.
The fi ne details of all the operations de-
pend on the specifi c requirements howe-
ver, and are therefore left to the instal-
ler's experience.
The unit is supplied complete with sup-
port brackets for wall or ceiling assembly.
The brackets can be assembled with the
bend pointing inwards or outwards.
For other types of assembly, the indica-
tions below should be modifi ed according

Installation - Connections
Aeraulic connections
WARNING!
It is prohibited to start the
machine if the fan inlets are
not ducted or are not protec-
ted by an accident-prevention system
For installation, proceed as follows:
• arrange suitable brackets to support
the channelling, so it does not weigh
on the recovery unit;
• connect the supply and intake ports
to the channels with vibration-dam-
ping joints in between (canvas). The
vibration-damping joint must be se-
cured to the panel with self-tapping
screws making sure that the canvas
joints are taught when running;
• arrange an earth cable that acts as
a bridge on the anti-vibration joint to
guarantee the equipotential connec-
tion between the channels and the re-
covery unit;
• before connecting any bends or bran-
ches, etc., set out the supply channel
with a straight section with a length of
at least 2.5 times the shorter side of
the channel A, avoiding an inclination
of more than 7° for the channelling
(to avoid any possible reduction in fan
performance levels).
Hydraulic connections: con-densate discharge
The condensate drip tray has a threa-
ded outlet with a diameter of 1/2” -G
UNI 338.
A discharge system must foresee a sui-
table drain-trap to:
• allow the free discharge of the con-
densate;
• prevent the undesired entry of air in
vacuum systems;
• prevent the infi ltration of odours or
insects.
The lower part of the trap should have
a discharge plug or should in any case
allow easy dismantling for cleaning.
The instructions for the dimensioning
and execution of the trap are as fol-
lows (see fi gure 21):
H1 = 2P
H2= H1 / 2
where P is the pressure of the water
column expressed in mm (1mm w.c. =
9.81 Pa).

ction, the piping must be carefully insu-
lated with suitable material as far as the
panelling.
Connection of the direct ex-pansion coils
The coils are supplied with connections
hermetically sealed and pressurised with
inert gas.
For correct installation follow the simple
indications below:
• the course of the piping must be
such so as not to create obstacles if the
coil needs to be removed, and not to
compromise the inspection and mainte-
nance of the unit and any accessories;
• arrange suitable brackets to support
the piping so as to avoid that their weight
overloads the recovery unit;
• once the connections have been made,
position the external rubber seal fl ush
with the panelling to avoid air seepage;
• the performance of the coil declared
in the present manual could undergo
changes in the event that the connection
pipes to a condensing only unit cause ex-
cessive pressure drops of the refrigerant.

Union base unit with accessories
All base units are designed to provide
easy confi guration and customization
through modular accessories to meet fully
the needs of the customer.To ensure this,
have been developed of how to merge
standard to simplify the connection
between the base unit and accessories
or even across multiple accessories
and the unit itself. It comes complete
with all the accessories provided, a kit
assembly composed of screws and fl at
sealing adhesive to be applied on the
walls in contact in order to prevent air
leakage between one or more modules.
The mounting of accessories may be
executed either when the machine to
the ground (in the case where this is a
new installation) of that machine already
installed.
We will hereafter consider the case of
union of units on the ground:
1a) remove the inspection panel on the
bottom of the accessory in order to allow
access to the inside of the assembly
accessory - base unit or accessory -
accessory.
2a) apply the self-adhesive gasket,

accessory that will be connected in order
to prevent air leakage during operation.
3a) to bring the two modules and
screwing together the brackets (top,
bottom and sides) of the two modules
using the screws metric supplied.
4a) close the panel inspection accessory.
In the case in which the base unit is
already installed and it should proceed
with the installation of an accessory
in a second moment, it can act in the
following way:
1b) remove the inspection panel on the
bottom of the accessory in order to allow
access to the inside of the assembly
accessory - base unit or accessory -
accessory.
2b) apply the self-adhesive gasket,
supplied with, on the edges of the

sharp.
WARNING!
After finishing the main-
tenance operations, make
sure that the panelling is correctly
closed by means of fixing screws.
The units of the FTA range have been
designed to require less maintenance,
and to make each operation easier.
Below are some simple instructions
for correct maintenance of the unit.
The maintenance program must in
any case be carried out by a qualified
technician.
Routine maintenanceRoutine maintenance consists of sim-
ple operations that should be carried
out monthly, as follows:
- check the tightness of the fans fi xing
screws to the panels;
- check that the machine's power sup-
ply cable has not undergone any al-
terations that could compromise its
insulation;
- make sure that the screws that fi x
the wires to the electrical components
inside the electric panel are tight so
as to guarantee an electrical connec-
tion; the same also goes for the earth
connections.
Maintenance of the filters (if present)The cleaning of the filters is funda-
mental in order to maintain a high
qualitative standard of air in the
room. The synthetic filters fitted to
the FTA unit can be regenerated using
compressed air or by washing them
in cold water. To disassemble the fil-
ters, observe the following indica-
tions (see the figure below):
• remove the inspection panel with
knobs;
• remove the filters;
• clean the filters;
• reassemble all the components in

fans, to maintain the low noise level
of the unit. Check annually:
- the clean state of the impeller;
- the noise level of the bearings.
Coil maintenance
It is essential to check and clean the
coils, to maintain the high standard
of quality and renewal of fresh air in
the room.
Check annually:
- the clean state of the finned unit.

Unit disposal
The components of the FTA range have
been designed to guarantee continual ope-
rations. The duration of some main parts
depends on the maintenance to which it
has undergone.
At the end of their useful life, the FTA
range units must be disposed of in accor-
dance with the current laws in force.
If the unit is to be disposed of, the opera-
tion must be carried out by speciali-
sed personnel.
The main materials that make up the
units of the FTA range are:
• galvanised steel (panels, fans, con-
densate drip tray);
• aluminium sheet or aluminium
alloy (coil fins, grilles, electric motor
frame);
• copper (coil pipes, winding of the
electric motors);
• polyurethane foam (sandwich panels
insulation).

3. NO AIR FLOW
RATE
1. Power supply off - Check the presence of power
2. Electric motor burnt out - Replace the electric motor
4. ABNORMAL
NOISE
1. Excessive flow rate - Reduce the flow rate
2. Fan bearings worn or defective - Replace bearings
3. Foreign bodies on the fans' impellers - Clean the impellers
4. MOISTURE
CARRYOVER
1. Drain-trap blocked - Clean drain-trap
2. No drain-trap or incorrectly made - Correctly prepare a drain-trap as
indicated in this manual
5. REQUIRED
TEMPERATURE NOT
ACHIEVED
1. Temperature of the inlet air on coil out-
side the envisaged limits - Check the water temperature
2. Air in the water coils - Bleed the coils
3. Insufficient water flow rate in the water
coils - Increase the water flow rate
4. Insufficient coil inlet water temperature - Check the water temperature
5. Dirty coil unit surface - Clean the surface of the pack
