Directive 2012/19/EC (WEEE): Information for users
This product complies with EU Directive 2012/19/EC.
The barred bin symbol on the appliance indicates that the pro-
duct, requiring separate treatment to household waste after its
normal working life, must be taken to a waste-sorting centre for
electrical and electronic appliances or returned to the retailer at
the time of purchasing a new equivalent appliance.
The user is responsible for taking the appliance to the appro-
priate waste collection centre at the end of its working life.
Correct waste sorting, with the discarded appliance being sent
for recycling, treatment and compatible environmental disposal
helps prevent any negative effects on the environment and
health, and encourages the recycling of product materials.
For further detailed information regarding available collection
systems, please contact your local waste disposal service or
the shop where you made your purchase.
Disposal rules for the old air conditioner
Before disposing of your old air conditioner, make sure that it is
off and unplug it. The refrigerant it contains requires a special
procedure for disposal. Materials of value in the air conditioner
can be recycled. Contact local authorities or the waste dispos-
al facility for more information. Make sure you do not damage
the pipes of the air conditioner before you take it to the waste
disposal facility. Help protect the environment by following a
correct, non-polluting method of disposal.
Disposal rules for the new air conditioner
packaging
All of the air conditioner packing materials can be disposed of
without harming the environment. The cardboard box must be
cut into pieces and delivered to a paper collection container. The
plastic and polystyrene packaging does not contain fluorine or
hydrocarbons.
All of these materials can be deposited in a waste dump and
recycled after proper treatment. Contact your local authorities
for information on waste disposal.
Battery disposal
The batteries have been designed and produced
with high quality materials and the components
can be recycled and/or re-used.
The symbol of the crossed-out rubbish bin
indicates that the product (batteries) at the end
of its useful life must be handled separately
from domestic waste and must be sent to a separate waste
collection center, as provided by the European Community
2006/66EC, art. 20 and annex II.
If under the bin there is a chemical symbol, this indicates that
the batteries have a certain concentration of heavy metal.and it
will be indicated as follows:
Hg: mercury (0,0005%), Cd: cadmium (0,002%), Pb: lead
(0,004%)

Description
FLASH is the new solution by BKL line, a significant step
towards reducing the aesthetic impact of air conditioners.
Being only 16 centimetres deep, FLASH is the thinnest
and less bulky in its category, therefore both the internal
and external aesthetic impact is kept to a minimum.
Optimised Capacities
The conditioning capacities of FLASH have been optimised
so as to obtain the right temperature for the best level of
comfort and, therefore, less consumption and less noise.
Thanks to the careful choice of sound insulation materials,
the noise is similar to that of a standard wall split unit and
consumption is drastically contained thanks to the new
direct current fan.
162 millimetre holes
An important choice not only design-wise, but also because
of a considerable installation advantage: it is easier to find
drilling tools as there's no need for professional ones, with
lower aesthetic impact.
BLDC inverter technology
We have perfected the inverter technology to offer the
best in terms of acoustic comfort (noise) and performance:
reduction of consumptions, maintenance of the best
temperature level and humidity level in the room.
Thanks to the use of the cutting edge BLDC (brushless
direct current) inverter regulation, vibrations have been
completely eliminated and acoustic emissions have been
lowered to exceptional levels.
Both ventilation motors are BLDC to reduce consumption
still further and make flow adjustment more precise.
Easy to install
FLASH can be installed on any perimeter wall either low or
high. Everything needed for installation (template, support
bracket, hole pipes and external grids), excluding the drill,
is included in the box.
Folding external grids
FLASH is equipped with folding grids activated by inlet
and outlet air. They open when the unit is working and
close when it's turned off. Better indoor comfort, less
dust, noise and pollution, less maintenance and even less
outdoor visibility.
Remote control and touch-screen display
In addition to the remote control, the touch-screen
display on the unit enables the setting of any function.
There's even a "lock" mode to avoid any improper use.
It is possible to deactivate the "heating" mode by simply
touching the screen. The unit then works in "cool only"
mode, without the need to use the condensation drain
pipe. The orientation of the air flaps can also be adjusted
by simply pressing one key.
Receipt and unpacking
The packing is made of suitable material and carried out
by expert personnel. All units are checked and tested and
are delivered complete and in perfect conditions, however
please perform the following instructions to check the
quality of shipping services:
- upon receipt, check if the box is damaged. If that is
the case, accept the goods with reservations and
keep photographic evidence of any damage found
- unpack and check the contents against the packing
list
- check that none of the parts have been damaged
during shipment.
Keep the packing at least for the whole length of
warranty should you need to ship the appliance to
the service centre for repair. Dispose of the packing
materials in compliance with current regulations on
waste disposal.
Storage
Handling
Store the box in a closed environment protected from
atmospheric agents and isolate it from the floor using
planks or pallets.
Do not turn upside down.
The unit is packed singularly in a cardboard box. Boxes
can either be carried singularly by hand by two operators
or loaded on a cart, for a maximum of three units.
Handling must be performed by qualified personnel,
with specific tools and with equipment suitable for the
weight of the appliance.
The appliance is unbalanced on the right (compressor
side)
During transportation, the appliance must be kept in
vertical position.

INSTALLATION
Before installing the conditioner, it is essential to calculate
the summer thermal loads (and winter ones for the models
with a heat pump) of the room. The more calculations are
exact, the better the product will work. Please refer to current
regulations to carry out calculations. For big installations
please call a study specialised in thermotechnics. Try to
reduce the thermal refrigeration load of the room following
instructions below:
- Cover large windows exposed to sunlight with curtains
or with external maskings (blinds, porches, reflecting
films, etc.).
- The room must remain closed for as long as possible.
- Avoid using halogen lamps or other high energy
consumption appliances such as small ovens, steam
irons, cooking plates etc.
For a better performance of the appliance and to avoid
malfunctions or dangerous situations, the location of the
unit must meet the following requisites:
- Respect the minimum distances indicated in the
picture.
- The wall on which you wish to anchor the unit must be
robust and able to support its weight.
- Leave enough space around the unit to perform
maintenance operations.
- Nothing must obstruct the air flow both in the top
suction part (curtains, plants, furniture) and in the lower
outlet part, as it could cause vibrations which might
prevent the appliance from working correctly
The appliance must be installed against a wall
communicating with the outside.
The appliance is stated as having an IPX0 protection
rating, therefore it is not suitable for outdoor installation.
Check that there are no structures or systems (beams,
pillars, hydraulic pipes, electrical cables etc.) in the part
that must be drilled. Check that nothing is placed in
front of the holes thus obstructing the air flow (plants
and leaves, panelling, shutters, thick grates or grids,
etc.)
The unit shouldn't be installed in a position where the
air flow aims directly at the people nearby;
Do not force the air flap open;
The appliance must not be installed directly above
another electrical appliance (TV, radio, fridge, etc.) or
above a source of heat.
