English
The fan coils are shipped in standard package which consists of expanded polystyrene foam and cardboard shells.
PACKAGING
Consult control panel manual for installation and use instructions.
USE
WARNING: electrical wirings, installation of the fan coils and relevant accessories should be performed by a technician who has the necessary technical
and professional expertise to install,
modify, extend and maintain systems,
and who is able to check the systems
for the purposes of safety and correct
operation.
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:before carrying out any
work, wear the proper personal protective equipment.
WARNING: the appliance must be fitted
according to the national regulations on
process plant engineering.
WARNING: check that the power supply is disconnected before carrying out
any procedures on the unit.
WARNING: install a device, main
switch or plug which allows to completely cut off the power supply from the
unit.
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, call the local
After-Sales Service immediately.
POWER THE FAN COIL ONLY WITH
230 VOLT, SINGLE PHASE, 50 Hz
Any other type of power supply could
permanently damage the fan coil.
DO NOT TUG THE ELECTRIC CABLE
It is very dangerous to pull, tread on or
crush the electric power cable, or fix it
with nails or drawing pins.
A damaged power cable can cause short
circuits and injure people.
DO NOT OBSTRUCT THE AIR
OUTLETS BY PLACING OBJECTS INTO
THEM
Do not put anything in the air outlet
slots.
This could injure people and damage
the fan.
DO NOT USE THE FAN COIL
IMPROPERLY
Do not use the fan coil for animal
husbandry applications (e.g. incubation).
AIR THE ROOM
Periodically air the room in which
the fan coil has been installed. This is
particularly important if the room is
occupied by many people, or if gas
appliances or sources of odours are
present.
ADJUST TEMPERATURE ADEQUATELY
The room temperature should be
adjusted in order to provide maximum
comfort to the people in the room,
especially if they are elderly, children
or sick people; avoid differences over
7°C between the outdoor temperature
and the temperature inside the room in
summer.
Carefully choose the room temperature
so as to save energy.
CORRECT AIR JET AIMING
ADJUSTMENT
Air coming out from the fan coil must
not reach people directly; in fact, even
if the air is warmer than the room
temperature, it could cause a cold
sensation and result in discomfort.
DO NOT USE EXCESSIVELY HOT
WATER
To clean the indoor unit, use soft cloths
or sponges dampened with water at a
maximum of 40°C. Do not use chemical
products or solvents 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
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 accumulated dust with a vacuum cleaner.
Once the filter is clean, refit it to the fan
coil following the removal instructions
but in reverse order.
The normal wear and tear of germicidal
lamps and filter is not covered by the
warranty.
SUPPLEMENTARY CLEANING
The possibility to remove the basin and
the shrouds of the examinable fans (done
only by suitably trained and qualified
personnel) allows to thoroughly clean
even the internal parts - an essential condition when the unit is installed in very
crowded areas or places requiring high
standards of hygiene.
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 accumulation of substances present in the air
of the room (clean the filter more often,
especially if the room is not ventilated
regularly).
While the unit is functioning, there
could be noises and creaks inside
the device due to the various thermal
expansions of the elements (plastic and
metal), but this does not indicate any
malfunction and does not damage the
unit unless the maximum input water
temperature is exceeded.
IMPORTANT INFORMATION

English
CON TROL PA NEL
The control panel (accessory) can only
be installed on the wall.
The AERMEC fan coil versions without
a control panel can all be combined
with the HSH AERDOMUS centralised
control system, using wired or wireless
connections.
Consult the control panel characteristics before selecting a panel.
ELECTRIC FAN ASSEMBLY
This consists of double suction centrifugal fans with lengthways blades to
obtain a high air flow with a low number of revs. The electrical motor, protected against overloading, has three speeds with the running capacitor always
on, directly coupled with the fans and
cushioned with flexible supports.
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 collecting condensation, with a connection
for draining condensation produced by
the unit in cooling mode. When there
are differences in levels, it is possible
to apply the accessory (DSC4) outside
the unit, complete with pump and water
level control device.
PLUMBING CONNECTIONS
The connections, located on the left
hand side, are female. The coil may also
be rotated.
DESCRIPTION OF COMPONENTS
SELECTION CRITERIA
The Coanda effect fan coil of the VEC
range must be installed in suspended
ceilings and is completed with the obligatory accessory VEC20GL.
The accessory VEC20GL consists of
the panel with suction from below and
delivery with adjustable diffusers that
allow the air to be distributed throughout the room, taking advantage of the
COANDA effect.
VEC must be combined with a control panel to be mounted on the wall.
Consult the characteristics and compatibility of the control panels supplied as
an accessory.
Some control panels can control a
network of fan coils if they are used in
combination with the interface cards
SIT3 and SIT5 supplied as accessories.
The AERMEC fan coil versions without
a control panel can all be combined
with the HSH AERDOMUS centralised
control system, using wired or wireless
connections.
The main technical data of the VEC fan
coils are summarised in the tables.
The table shows the sensible and total
refrigerating yield at maximum speed,
on the basis of the inlet water temperature, its temperature change, and the
dry bulb and wet bulb air temperature,
for sensitive yield and total yield respectively, for versions with a 3-row coil.
Performance levels at average and minimum speed are obtained by multiplying
the values by the correction factors indicated.
The water side pressure drops are
shown in the diagrams.
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 yield, on the
basis of the water flow rate and the
difference in temperature between the
incoming water and the incoming air, is
represented in a graph and refers to the
maximum speed. Performance levels at
average and minimum speed are obtained by multiplying the values shown on
the graph (at maximum speed) by the
correction factors indicated.
The pressure level and sound output
of the fan coils at the various speeds are
shown in the tables.
The installation information is included 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 control panels.

If the fan coil is working in cold
continuous mode inside an environment
where the relative humidity is high,
condensate might form on the air
delivery. This condensate might be
deposited on any objects underneath
and on the floor.
To avoid condensate on the external
structure of the device while the fan is
functioning, the average temperature of
the water must not be lower than the
limits shown in the table below, that
depend on the thermo-hygrometric conditions of the air in the room.
The limits mentioned above refer to
operation while the fan is set
to its minimum speed level.
In the event of prolonged fan inactivity
and with cold water passing through the
coil, condensate may form on the external case of the unit. As a result, we rec-
ommend including the three-way valve
accessory.
OPERATING LIMITS
In order to prevent air stratification
in the room, and therefore to achieve
improved mixing, it is obligatory not
to supply the fan coil with water at a
temperature over 65°C.
The use of water at high temperatures
could cause squeaking due to the
different thermal expansions of the
elements (plastic and metal), this does
not however cause damage to the unit if
the maximum operating temperature is
not exceeded.

OBLIGATORY ACCESSORIES
KTLP
VEC_GL allows 2 installation positions:
A) for suspended ceiling installation
with reduced space that requires units
with small dimensions.
B) allows (increasing total height)
to increase the difference in level
between condensate drain and
suspended ceiling by a further 30
mm, to make the realisation of the
condensate drain ducting even easier,
in order to prevent, in most cases,
the necessity for a condensate drain
pump. In this case it is mandatory to
apply the insulating gasket to the filter
retainer divider (supplied) to prevent
by-pass between intake and flow.
Moreover, after having fixed the frame
to the fan coil using the 4 screws,
apply the insulating tape (supplied)
to the entire exposed perimeter of the
frame.
WARNING: No or incorrect
installation of the insulating products
caused the reduction in performance
and the formation of condensate on
the surfaces.

The unit must be connected directly
to an electrical outlet or to an
independent circuit.
To protect the unit against short circuits, fit an omnipolar thermal-magnetic
trip 2A 250V (IG) to the power line
with a minimum contact opening
distance of 3mm.
CHARACTERISTICS OF THE
CONNECTION CABLES
Use H05V-K or N07V-K type cables
with 300/500V with insulation, piped
or ducted.
All the cables must be piped or ducted
until they are inside the fan coil.
The cables coming out of the pipe or
duct must not be subject to stretching
or twisting. They must be protected from
external agents.
Stranded wires can only be used with
terminating sleeves. Make sure that the
strands of the wires are inserted properly.
Wiring diagrams are constantly updated. It is therefore compulsory to refer
to the ones supplied with the unit.
The control panel may not be fitted on
a metal wall unless this is permanently
connected to an earthed outlet.
The control panels consist simply of
electric circuits connected at the mains
voltage of 230V; all the inputs for the
probes and controls must therefore be
correspondingly insulated for this voltage.
Multifunctional electronic thermostats
are provided ready for operation in the
standard configuration but allow the
installer to adjust them to the specific
necessities of the system by modifying
the internal dip-switch configuration.
The functions that can be customised might
vary from model to model, for this reason it
is advisable to consult the relevant manuals.
WARNING:check whether the installation has been carried out correctly. FOLLOW THE CHECKING PROCEDURES indicated in the control panel
manuals.
INSTALLATION
INSTALLING THE UNIT
ELECTRICAL WIRINGS
WARNING: before carrying out any
intervention, check the power supply i
s
disconnected.
WARNING:before carrying out any
work, put the proper individual
protection equipment on.
WARNING: the appliance must be fitted
according to the national regulations on
process plant engineering.
WARNING: electrical wirings,
installation of the fan coils and relevant
accessories should be performed by
a technician who has the necessary
technical and professional expertise
to install, modify, extend and maintain
systems, and who is able to check the
systems for the purposes of safety and
correct operation.
WARNING: install a device, main
switch or plug which allows to
completely cut off the power supply
from the unit.
Instructions which are essential for the
proper installation of the equipment are
given here.
The completion of all the operations
in accordance with the specific
requirements is however left to the
experience of the installation engineer.
Do not install units in rooms where
there are inflammable gases or acid
or alkaline substances that could
irretrievably damage the aluminiumcopper heat exchanger or the internal
plastic parts.
Do not install the unit in workshops or
kitchens where the oil vapours mixed
with the treated air can be deposited
on the exchange coils, reducing their
performance, or on the parts inside the
unit, damaging the plastic parts.
Choose a position at the centre of the
room whenever possible; adjusting the
air output allows air to be distributed
optimally within the room. Do not
install at a height above three metres.
- Choose the place where to install
the unit according to the layout of
the room, the number of units to be
installed and any limitations imposed
by the architecture. Check that the
ch
osen place facilitates installing and
servicing the unit.
- Install four M8 threaded rods into the
ceiling to hold the frame.
VEC allows 2 installation options thanks
to the grill prepared to be fixed in two
positions:
A) for suspended ceiling installation with
reduced space that requires units with
small dimensions.
B) allows (increasing total height)
to increase the difference in level
between condensate drain and
suspended ceiling by a further 30
mm, to make the realisation of the
condensate drain ducting even easier,
in order to prevent, in most cases,
the necessity for a condensate drain
pump.
To install the VEC unit, proceed as
follows:
- open the cardboard box
- if necessary, mount any accessory
before installing the unit on the ceiling
WARNING: consult the relevant
manuals of the accessories
- lift the unit carefully a
nd, keeping it
slightly inclined, attach it to the 4
threaded bars using 8 nuts, 4 of which
are self-locking. Operate the nuts
to adjust height; finally, check that
the unit is installed in a horizontal
position
- lay the hydraulic pipes through the
suspended ceiling to the attachment
plate on the unit
- make the hydraulic connections as
described in the relative chapter
- bring the condensate discharge pipe
so that it matches the relative fitting on
the condensate discharge device
- drain the system via the drain valve
- bring the power supply and the
control cables close to the electrical
box
- adjust the position of the unit from the
support bracket by means of the nuts
so that the unit is level and the frame
rests slightly on the suspended ceiling

TROUBLESHOOTING
Interventions:
- External cleaning, weekly, to be carried
out with a damp cloth (
dipped in water
maximum 40°C)
and neutral soap; avoid
any other type of detergent or solvent.
- Do not spray water on the outer or
inner surfaces of the fan coil (this could
cause short-circuiting).
- Visual inspection of the state of the fan
coil for every maintenance operation;
any anomaly must be reported to the
After Sales Service.
MAINTENANCE
Routine maintenance can be carried out
by the user: it involves a series of simple
operations, thanks to which the fan coil
can operate at its maximum efficiency
level.
Before carrying out any work, make
sure the electricity supply is unplugged.
Do not remove the shell or the
mechanical/electrical protection
devices.
Interventions:
- Internal cleaning, once a year or before the machine is shut
down for a long period. In rooms where a high level of air
cleaning is requested, the cleaning intervention can be made
more often. It consists in the cleaning of the coil, fan louvres,
basin, ioniser, and all the parts in contact with the treated air.
Check also the condition of the filter, cleaning or replacing it if
necessary.
Do not use jets or sprays of water during the cleaning.
Use the brush to remove any dust deposits.
- Repairs and fine tuning: if you notice anomalies, consult the
“TROUBLESHOOTING" chapter of this manual before contacting the After Sales Service.
Extraordinary maintenance must only
be carried out by Aermec After Sales
Service centres, or by technicians with
the technical and professional requisites
for the installation, transformation,
amplification and maintenance of the
systems, and able to check these aspects
in terms of safety and good working.
For the electrical wiring in particular,
checks relating to the following aspects
are required:
- Measurement of the electrical system
insulation resistance;
- Continuity test of the protection wires.
Extraordinary maintenance consists of a
set of complex operations that involve
the dismantling of the fan coil or its
components, resulting in the restoration
of the fan coil's functioning at maximum
efficiency.
Before carrying out any work, make
sure the electricity supply is unplugged.
