PACKAGING
IMPORTANT INFORMATION AND MAINTENANCE
Consult the control panel manual for operating instructions.
USE
WARNING: the electrical wirings, the
installation of the fan coils and their
accessories, maintenance and the yearly
replacement of the germicidal lamps
must be performed only by a techni-
cian who has the necessary technical
and professional qualifications to install,
modify, extend and service the systems
and who is capable of assessing these
systems for the purposes of safety and
functionality.
WARNING: before carrying out any
work, wear the proper personal protec-
tive equipment.
WARNING: the fan coil is connected to
the power supply and a water circuit.
Any operation by persons who do not
possess the required technical skills can
lead to personal injury to the operator
or damage to the unit and surrounding
objects.
WARNING: The appliance must be fit-
ted according to the national regulation
on process plant engineering.
WARNING: Check that the power sup-
ply is disconnected before carrying out
any procedures on the unit.
WARNING: Install a device, main switch
or plug which makes it possible to com-
pletely cut off the power supply from
the unit.
DANGER! The UVC radiation emitted
by the germicidal lamp is dangerous
and may cause conjunctivitis, burns and
erythema.
It is absolutely prohibited to operate the
device with the germicidal lamp when it
has been removed from the fan coil.
It is absolutely prohibited to operate
the device with the germicidal lamp if
the fan coil has not been adequately
installed.
WARNING! DANGER! Any use of the
unit not expressly indicated by Aermec
is strictly prohibited.
MALFUNCTIONS
In the event of a malfunction, cut off
power supply to the unit, then restore
the power and start the unit again.
If the problem occurs again, contact
your After Sales Service department
immediately.
ONLY POWER THE FAN COIL AT
230 VAC 50 HZ
Any other type of power supply could
permanently damage the fan coil.
DO NOT USE THE FAN COIL IMPROP-
ERLY
Do not use the fan coil in animal hus-
bandry applications (e.g. incubation).
AIRING THE ROOM
Periodically air the room in which the
fan coil has been installed. This is partic-
ularly important if the room is occupied
by many people, or if gas appliances or
sources of odours are present.
DURING OPERATION
Always leave the filter fitted on the fan
coil during operation (otherwise dust in
the air could soil the coil surface area).
CORRECT TEMPERATURE ADJUST-
MENT
The room temperature should be regulat-
ed in order to provide maximum comfort
to the people in the room, especially if
they are elderly, children or ill; avoiding
temperature differences of more than 7°C
between outside and inside the room in
summer.
In summer, a temperature that is too low
causes higher electrical consumption.
CORRECT AIR JET AIMING ADJUST-
MENT
The air coming out of the fan coil must
not impact directly on people; in fact,
even if temperature is higher than the
room temperature, it could cause a cold
sensation resulting in discomfort.
DO NOT USE EXCESSIVELY HOT
WATER
Clean the fan coil with a soft cloth or
sponge soaked in water not over 40 °C.
Do not use chemical products or sol-
vents to clean any part of the fan coil.
Do not spray water on the outer or inner
surfaces of the fan coil (it might cause
short circuits).
CLEAN THE FILTER FREQUENTLY
Before performing any maintenance pro-
cedures requiring access to the internal
parts of the fan coil, cut off the power
supply in order to avoid being exposed
to the light emitted by the lamp.
Cleaning the filter frequently guarantees
enhanced operating efficiency.
Check whether the filter is very dirty: if it
is, clean it more often.
Clean frequently; remove the accumu-
lated dust with a vacuum cleaner.
Once the filter is clean, refit it to the fan
coil following the removal instructions
but in reverse order.
SUPPLEMENTARY CLEANING
Before performing any maintenance pro-
cedures requiring access to the internal
parts of the fan coil, cut off the power
supply in order to avoid being exposed
to the light emitted by the lamp.
The fact that the blades of inspectable
shrouds can be removed (operation done
only by adequately skilled technicians)
ensures a thorough cleaning of the inter-
nal components, which is particularly
important when installing the unit in
crowded areas or venues requiring high
hygiene standards.
WHAT IS NORMAL
In the cooling function, water vapour
may be present in the air delivery of the
fan coil.
In the heating function, a slight hiss
might be heard close to the fan coil.
Sometimes the fan coil might give off
unpleasant smells due to the accumula-
tion of substances present in the air of
the environment (clean the filter more
often especially if the room is not venti-
lated regularly).
During the operation, there could be
noises and creaks inside the device, due
to the various thermal expansions of the
elements (plastic and metallic), but this
does not indicate any malfunction and
does not damage the unit unless the
maximum input water temperature is
exceeded.
REPLACING THE LAMPS
This procedure may only be performed
by people with the necessary specific
technical skills.
Before performing any maintenance pro-
cedures requiring access to the internal
parts of the fan coil, cut off the power
supply in order to avoid being exposed
to the light emitted by the lamp.
Never let yourself come into direct con-
tact with the light produced by the lamp,
as the UVC radiation may cause serious
eye and skin irritation.
Lamps should be replaced every year
in order to ensure that the germicidal
action remains constant.

FHX - FAN COIL WITH GERMICIDAL LAMP
The FHX fan coil concentrates high technological and func-
tional characteristics that make it the ideal climate control unit
for all types of rooms. The supply of climate-controlled air is
immediate and distributed throughout the room. FHX gener-
ates heat if included in a heating system with boiler or heat
pump, but may also be used in summer as an air conditioner if
the heating system has a water chiller.
The FHX fan coil is fitted with an exclusive device featuring
a mercury-vapour germicidal lamp for air sterilisation, offer-
ing anti-microbiological action which is 99.999% effective in
combating all Gram - and Gram + microorganisms. The germi-
cidal lamp, positioned in the air delivery flow, cleans the coil
more thoroughly and prevents the formation of mould on the
surface of the fins, thereby ensuring the unit operates at its
maximum efficiency level in the long term, while reducing the
need for coil cleaning procedures.
The fact that the tray and the fan shrouds can be inspected
means you can carefully clean the internal parts as well.
These characteristics make the FHX unit indispensable in ven-
ues requiring high hygiene standards, such as:
• hospitals
• dentists' surgeries
• doctors' and vets' consulting rooms
• clynical analysis laboratories
• pharmaceutical companies
• waiting rooms
• beauty salons
• homes
• offices
• public premises
The new centrifugal fan unit is so quiet that at a normal oper-
ating speed you cannot hear when the FHX cuts in.
All models in the FHX range are supplied without a control
panel.
The PXAI and PXAE combinable control panels are supplied as
accessories; they activate the germicidal lamp operation as well
as the ventilation function, and are fitted with an electronic ther-
mostat which controls fan coil operation in order to maintain the
set temperature in the room. They also make electronic tempera-
ture adjustment and manual/automatic fan speed adjustment
possible, while the heating or cooling operating mode is selected
automatically (change of season) and depends on the temperature
of the water circulating inside the system.
The PXAI control panel may be fitted underneath the flap to the
right of the FHX_UV fan coil.
The PXAE control panel to be wall-mounted may be used com-
bined with all versions of the FHX range.
The fan coils in the FHX range are designed to satisfy all
system requirements, thanks to the wide range of accessories
available.
Full compliance with accident prevention regulations.
Congratulations on your purchase of this Aermec FHX fan coil.
Made with materials of superior quality in strict compliance with safety regulations, "FHX" is easy to use and will
have a long life.

MAIN COMPONENTS
HEAT EXCHANGE COIL
Coil with copper pipe and alumini-
um fins held in place by means of the
mechanical expansion of the pipes. The
manifolds are fitted with female connec-
tions and air vents in the upper part of
the coil.
FILTRATION SECTION
Easily removable and made from regen-
erable materials. May be cleaned by
washing.
P and PO versions are equipped with G2
class filter.
CABINET
Casing in RAL9002
Air delivery and suction louvers in
RAL7044
Made from specially treated, polyester
powder-coated sheet metal to ensure
superior rust and corrosion resistance.
UV Version : at the upper part, there are
the louver (it is orientable and can be
closed again for sizes 22; 32; 42 and 50;
flat and fixed for sizes 62 and 82), made
from thermoplastic material to distribute
air, and the door to access the control
panel. With the orientable louver fully
closed, the tripping of the microswitch
stops ventilation, thus interrupting any
further heat exchange with the environ-
ment.
The casing also features a ther-
moplastic air recirculation louver at the
front.
ELECTRIC FAN ASSEMBLY
It consists of double suction radial fans
with lengthways blades to obtain a high
air flow with a low number of revs. The
electrical motor, protected against over-
loading, has three speeds with the run-
ning capacitor always on, directly cou-
pled with the fans and cushioned with
flexible supports. The FHX UVPO ver-
sion is equipped with a boosted motor
set to operate at 7 speeds (3 of which
may be selected).
BEARING STRUCTURE
Made of galvanised sheet metal of an
adequate thickness. Hole in the back
for wall mounting. A fan cover panel is
available for front-mounted ceiling units.
Each unit is equipped with a condensate
collection tray.
CONDENSATE DRAIN
Every device is fitted with a tray for col-
lecting condensation, with a connection
for draining condensation produced by
the unit in cooling mode.
PLUMBING CONNECTIONS
The connections, located on the left
hand side, are female. The coil may also
be rotated.
GERMICIDAL LAMP
Germicidal lamp that emits UVC rays.
This lamp has a one-year life span; after
that time, it should be replaced with a
similar lamp. The lamp serves to prevent
mould from forming in the fan coil, to
eliminate microbiological contamination
and to avoid its spread into the room.
The UVC radiation emitted by the lamp
destroys the main cellular DNA and
RNA.
The immediate effect is that cells cannot
reproduce and are killed; therefore, the
risk of airborne-transmitted infections is
reduced up to 90%.
Germicidal lamps emitting UVC rays
installed in the fan coils can prevent:
- TB conversions within healthcare facili-
ties.
- Legionnaire's disease.
- Microorganisms in the discharge cir-
cuits.
- Contaminated filters or overpressure.
- Spread of infections.

SELECTION CRITERIA
Models with universal cabinet (UV) fea-
ture a front intake and can be mounted
either vertically on a wall or horizon-
tally on the ceiling.
Wall/ceiling-mounting (UVP and UVPO)
versions, without protective cabinet
and with intake at the bottom, can be
installed either vertically or horizontally.
In case of ducted installations where
pressure drops in the ducts are consid-
erable, the UVPO model (with boosted
multi-speed motors) enables to have the
effective pressure needed to guarantee a
correct air flow rate.
The UVP and UVPO models are avail-
able with 3- and 4-row coils.
The UV model has to be combined with
a control panel to be installed internally
or externally. Consult the characteristics
and compatibility of the control panels
supplied as accessories.
The UVP and UVPO models have to be
combined with a control panel to be
installed externally. Consult the charac-
teristics and compatibility of the control
panels supplied as accessories.
The control panels can control a net-
work of fan coils if they are used in
combination with the interface cards
SIT3 and SIT5 supplied as accessories.
The main technical data of the FHX
range are summarised in the tables.
The total and sensible cooling capacities
yielded at maximum speed according to
the temperature and thermal head of
the incoming water, the air temperature
with dry bulb or wet bulb for sensible
yield and total yield respectively for
models with a 3-row coil are shown
in the table. Performances at medium
and minimum speeds can be obtained
by multiplying the values in the table
by the correction factors indicated; for
4-row coil models, by multiplying the
values in the table by the correction fac-
tors indicated for each speed.
Pressure drops on the water side for 3-
and 4-row coils respectively are shown
in the graphs.
The correction factors when the unit
operates with glycol water for cooling
and heating function modes are shown
in the graphs in percentages of glycol of
10%, 20% and 35%.
The heating capacity yielded by the 3-
and 4-row coils according to the water
flow rate and the difference in tem-
perature between the incoming water
and the incoming air is represented in
a graph and it refers to the maximum
speed. Performances at medium and
minimum speeds can be obtained by
multiplying the values obtained from
the graph at maximum speed by the
correction factors indicated.
For the ducted wall/ceiling-mounting
models (UVP and UVPO), the perform-
ances described before must be con-
sidered as referring to air flow rates
equal to those corresponding to the
(UV) models at maximum speed (rated
capacities).
The pressure for the wall/ceiling-mount-
ing models according to the air flow
rate and the fan speed are shown as
a table; the curves show each speed.
For scaling the ducted wall/ceiling-
mounting models, it is advisable to pro-
ceed as follows: choose the size that
given a normal flow rate has a power
immediately above that required; after-
wards, mark out the curve of the duct
pressure drops on the rate-pressure dia-
gram related to the machine in ques-
tion in order to individualise the points
of machine operation at the different
speeds. Based on the capacity values
of these points, you will obtain the cor-
rection factors that help calculate the
capacity yielded given the actual condi-
tions of air flow rate. For multi-speed
models, this procedure helps to suitable
choose the speeds to be set.
The pressure and sound power levels
of fan coils at the different speeds are
shown in separated tables for 3- and
4-row coils models. For the ducted wall/
ceiling models, the sound power level
is expressed according to the air flow
rate and pressure, and represented as
graphs.
There is a wide range of accessories for
FHX fan coils, sometimes some of them
cannot be used at the same time; check
that the accessories are compatible with
the fan coil chosen. The manual shows
the description of each accessory plus a
drawing and its compatibility.
The installation information is includ-
ed in the manuals supplied together
with each fan coil or its accessory. This
manual is limited to provide general
information in order to obtain a correct
installation; it also contains drawings
with fan coil dimensions and the wiring
diagrams with the connections to con-
trol panels.

To avoid condensate forming on the external structure of
the unit while the fan is functioning, the medium water
temperature must not be lower than the limits shown in the
table below, that depend on the thermohygrometric condition
of the air in the room.
These limits refer to unit operating with fan at minimum speed.
In the case of a prolonged situation with the fan off and the
passage of cold water in the coil, condensation can form on
the outside of the unit, so it is recommended that a 3-way valve
accessory be fitted.

NB: The yield values in bold type indicate the nominal value.
If sensible yield values are above the total output, this means that cooling is carried out without dehumidification. If this occurs,
take into consideration only the sensible yield values.
The cooling capacities yielded shown in the table must be multiplied by the following factors:
