INSTALLATION
Valid for models: K7
•Recessed unit K7
MAX. Maximum recommended height, MIN. Recommended minimum distance
(**) Removable sides
•Recessed unit K7 Stainless Steel IP55
MAX. Maximum recommended height, MIN. Recommended minimum distance
(**) Removable sides
The minimum recommended distance between the intake grille and any obstacle is 200mm.
Assembly, connection and disconnection, electrical wiring and maintenance must be
carried out exclusively by qualified personnel, observing these instructions and in
accordance with the applicable standards. In case a special control is supplied, a
specific manual is attached that must be used for its operation and installation.
Depending on the model it is not necessary to remove the service grill to connect the
equipment. All the connections (power and control) and necessary fixings are external
(in the standard case, located on the top or side of the purifier), internal (in the case of
having Clever Control) or in the external waterproof box (in the case of having IP
protection). The equipment has a service grid to place the consumable cartridge and
carry out repairs (see repairs section).

Power supply
Depending on the model, you have to access different sites to make your connection:
K7 600 A OH+FC (with standard control) -> On one of the outer sides there is the power board, where the
power must be connected.
K7 600 A OH+FC CL (with advanced Clever control) -> On one of the outer sides there is a black box where
the power supply must be connected.
K7 600 A OH+FC SS (IP55 standard control) -> There is a waterproof box above the purifier where the power
must be entered and connected to the internal terminal block by means of a cable gland.
PCB and control
Depending on the model, you have to access different sites to make your connection. All models include an
RJ telephone cable to communicate with the control.
K7 600 A OH+FC (with standard control) -> using the 7-meter RJ45 cable, connect the power board (located
on one of the outer sides of the purifier) and the control. In this case, it is not necessary to open the intake
grille.
K7 600 A OH+FC CL (with advanced Clever control) -> using the 7-meter RJ11 cable, connect the Clever
regulation board (located inside the equipment) and the TFT control of the Clever. In this case, it is necessary
to open the intake grille (see section “repairs and replacements”). The RJ11 cable must be routed to the
outside through a hole in the top of the housing.
K7 600 A OH+FC SS (IP55 standard control) -> using the 7-meter RJ45 cable, connect the power board
(located in the waterproof box above the purifier) and the control (located inside an IP65 waterproof box). To
enter the cable in each box, you must use the cable glands supplied with the purifier.
The communication between the controller and the board is digital and low voltage.
There are optional accessories and controllers designed to meet the needs of each client (Clever, brackets,
etc.).
The new generation of total control is the Clever control. It leads the new generation of regulation with
maximum control that provides maximum energy efficiency. In addition, it allows you to visually monitor the air
quality and the status of the disinfection function. For more information request the Clever manual.
Fixings
The equipment has several external attachment points (see situation in the model characteristics section).
The anchor must be dimensioned according to the K7 weights indicated on the technical data page.
Installation can be done using threaded rods, turnbuckles or other supports. See available supports in the
accessories section.

TRANSPORT AND STORAGE
OPERATING INSTRUCTIONS
Attention! Heavy product.
Do not stand under the suspended equipment during transport or assembly.
Store in a dry place protected from the elements. If the packaging is open, cover the purifier to protect it from
dust. Do not step on or place heavy load son it to avoid damage to he material. Storage temperatura between
-20ºC and +40ºC.
When transporting the material, make sure that it is not damaged by the forklift (penetration of the fork in the
packaging). The instructions on the packaging must be observed.
Includes a consumable with disinfectant liquid (hydrogen peroxide solution).
(EN) PRECAUTIONS: Causes skin irritation.Causes serious eye irritation. It can irritate
the respiratory tract. Avoid breathing dust/fume/gas/mist/vapors/spray. Wash hands
and forearms thoroughly after handling. Use only outdoors or in a well-ventilated área.
Wear protective gloves/clothing/glasses/mask. IN CASE OF SKIN CONTACT: Wash
with plenty of soap and wáter. IN CASE OF INHALATION: Remove person to fresh air
and keep in a position that facilitates breathing. IN CASE OF CONTACT WITH EYES: Rinse carefully with
water for several minutes. Remove contact lenses when present and can be done easily. Continue with the
wash. In case of skin irritation: Consult a doctor. Immediately call a POSISON CENTER or doctor. Remove
contaminated clothing. Store in a well ventilated place. Keep the recipient hermetically sealed. Keep locked
up. Dispose of contents/container to an approved waste disposal facility.
Control board features
The relay boards adjust the two fan speeds depending on the condenser connection.
Standard controller features
•2 ventilation speeds.
•Memory: guarantees that, in the
evento o fan interruption in the power
supply, the speed that we had
selected is preserved when the
service is restored. This function can
be connected-disconnected using the
ON/OFF switch located inside the
controller.
•RJ45 cable and digital communication: they have a fast
connection with a telephone type cable and digital
communication between the controller and the purifier. This
type of communication is reliable even over long distances.
•External start-stop: inside the controller there is the possibility of connecting a normally open contact
(1,2) that governs the on-off of the equipment through any external device. The contact is potential
free. When the contact is open then the purifier is on. When the contact closes the purifier has a 30
second delay before stopping. It can be used for a timer, temperature sensor, fire alarm, PLC, etc.

8
•Remote control: all standards controls have an IR receiver that allows you to use a remote control.
•End of consumable: when the level sensor of the disinfectant cartridge sends the signal through the
board, the control flashes the zero-speed led (red led). In this way the user is notified that the cartridge
must be changed. The ventilation of the purifier continues its operation as it did before the
consumable was finished. Only hydroxyl radicals stop working.
Special controls
If there is a need to control more parameters, there is an advanced control, the Clever. It has its own manual
where all its functions are explained.
