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.

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.

MAINTENANCE INSTRUCTIONS
For safety, before cleaning, turn off the appliance using the controller.
It is forbidden to open the service grille (risk of electric shock, trapping in fans and
glare from UV-A light).
Repairs must be carried out exclusively by authorized personnel.
The inside of the appliance must not be cleaned with water or steam.
Exterior cleaning
It is recommended to clean the intake grille weekly. In addition, it is important to make sure that the purifier is
turned off, on the contrary, the mixture between dust and a damp cloth would form a kind of paste that could
damage the fan rotor when it sucks in the air.
An annual cleaning of the discharge area should be performed.
Cleaning the body of the purifier should be done with a damp cloth and a conventional detergent. Do not use
caustic or acid-containing detergents.
The intake grille prevents objects from entering the internal elements. It is advisable to periodically check that
the intake grille is free of any object that could prevent the entry of air (papers, etc.).
Internal cleaning
In models with perforated grille, it is advisable to clean the inside of the unit with a vacuum cleaner at least
once every 2 years (*), better to do it before winter, using qualified personnel.
It is recommended to clean the inside of the equipment frequently with the help of a vacuum cleaner. (*)
(*) These periods are indicative depending on the conditions of each installation. In places with a high number
of suspended particles it is desirable to increase the frequency of interior cleaning.

FAILURES AND SOLUTIONS
More than 95% of the complaints are submitted during the start of operation of the equipment and are due
to installation errors. Reviewing the following 3 points, more than 90% of the incidents are solved:
A) RJ45 cable manipulated: The cable that connects the controller to the air purifier is an 8 lines crossed RJ45 cable. If
manipulated (cut or removed the connector) and incorrectly joined (reverse way) the purifier Will not work well. Moreover
it can damage the electronics. To solve the problem just turn the connector of the cable (see connection diagram in the first page).
B) Wrong connection of the RJ45 cable. Verify whether the connector position is the correct, between the “control”and “auxiliary”,
according to the installation diagram (particularly if there are several purifiers with a single controller).
C) Wrong current supply/input.The purifier input depends on the type of current available and also on the heating type of the unit.
Connect the unit according to the connection diagrams of the first page.

Is the RJ45/RJ11 cable the original
(not manipulated), with no
enlargements either shortenings?
Change cable or reconnect it correctly.
Does the current reaches the
connection box?
Correctly connect the terminals of the connection box:
Between L and N there must be 230V.
Is the controller connected to the
purifier, to the connector “Control”
of the PCBoard?
Connect the cable from the controller to the “Control”, never to the “Aux”.
Is the fuse of the PCBoard in good
conditions?
Check the fuse and replace it in case it is necessary (type T, slow action)
Is the grille in place?
Place the grille in the corresponding position and close the equipment
Some lights of the
controller are flashing
Zero speed light blinks
The consumable has run out and needs to be replaced
The speed changes
continuously
with no apparent
reason but the
lights of the
controller are not
flashing.
Probably the RJ45 cable is near
interference sources, transmitters,
cable plates, particularly those that
supply current to motors, etc.
Pass the cable the furthest possible away from interference sources,
particularly when long distances or use a screened table.
