INSTALLATION
Assembly, connection and disconnection, electrical wiring and maintenance must be
carried out exclusively by qualied personnel, following this instruction manual and
respecting the applicable regulations. In case of supplying a special control, a specic
manual is attached that must be used for its installation and operation.
It is necessary to remove the service grill to connect the equipment. The electrical
connection is made in an IP box located inside the equipment. The equipment
mountings are external (in the standard model, located on the top or rear of the
purier). The unit has a service door to place the lters and a second panel to carry
out repairs (see repairs section).

TRANSPORT AND STORAGE
OPERATING INSTRUCTIONS
Store in a dry place and protected from the environtment. If the packaging is opened, cover the purier
to protect it from dust� Do not step on or place heavy loads on it to avoid damage to the material�
Storage temperature between -20⁰C and + 40⁰C.
When transporting the material you must ensure that it is not damaged by the forklift (possible penetration of
the fork in the packaging)� Observe the instructions on the packaging�
To put the device into operation, just connect it to a voltage of 230Vx1 50 / 60Hz, as indicated in the
electrical diagram on the next page. This device works with a constant ow rate that the user does not
need to congure. The fan regulates itself to maintain a ow rate of 300m³ / h until the lters are dirty.
When the lters are no longer able to hold particles, a red light comes on. This indicates that dirty lters
should be replaced with clean ones. Furthermore, the team cannot guarantee that the ow (and consequently
the renewals / hour) will be maintained until clean lters are installed.
ATTENTION! Heavy object.
Do not stand under the suspended load during transport or assembly.
Power supply
Fixings
The K7 770 A HEPA air purier has a 3 meter, 3-way cable (line, neutral and ground) that must be connected
to a 230Vx1 50 / 60Hz power outlet�
A switch can be connected between the unit and the inlet power.Therefore you can disconnect the equipment
in a simple way�
The equipment has several external attachment points located in the casing, either in the top, front and back
sides� The anchor must be sized according to the device weights indicated on the technical data page (see
pages 6-7)� The installation can be carried out with threaded rods, tensioners or other supports (see section
“accessories”)�
Autoregulation
This unit provides a constant air ow of 300 m³ / h. As the lters get dirty, K7 770 A HEPA regulates itself to
maintain a constant ow.
The equipment is already factory adjusted by default. It only needs to be powered with 230Vx1 50 / 60Hz
current�

Functioning
Three air and surface purication and disinfection systems in a single unit. Air recirculation through a HEPA lter and
expansion of hydroxyls thanks to active OH technology and photocatalysis fan guarantee a space free of pathogens and
other volatile organic compounds that pollute indoor air.
The LED on the service panel indicates either the lter or cartridge change to be carried out to maintain the eciency of
the equipment.

MAINTENANCE INSTRUCTIONS
For safety, before cleaning, disconnect the device from the power.
It is forbidden to open the service panel (risk of electric shock and trapping
in the fans). Repairs must be carried out exclusively by authorized personnel.
The interior of the device must not be cleaned with water or steam.
Exterior cleaning
It is recommended to clean the air inlet grille with a damp cloth� Cleaning must be done with the
unit o󰀨; the mixture of dust and moisture generates a paste that could enter and a󰀨ect the
internal components, rendering them unusable before the estimated deadline�
An annual cleaning of the air outlet area should be performed�
Cleaning of the unit casing should be done with a damp cloth and conventional detergent�
Do not use corrosive, caustic or acid-containing detergents�
The air inlet grille prevents objects from entering the internal area� A periodical checking is convenient to
ensure that it is free of any object that could prevent the entry of air (papers, plastics, etc�)�
Interior cleaning
In models with perforated grille, it is advisable to clean the inside of the unit with a vacuum cleaner, at least
once every two years (*), and by qualied personnel.
(*) This period of time is indicative, it depends on the conditions of each installation�
In places with a high number of suspended particles (a lot of dust and dirt) it is desirable increase the
frequency of interior cleaning.

The assembly and electrical connection must be carried out exclusively by
specialized professionals and observing these instructions.
Before carrying out any repairs, you must:
• Notify sta and indicate that work is in progress.
• Disconnect the current and protect the thermal magnet
(so that no one can actuate it by accident)
• Make sure there is no voltage on the unit.
• Make sure the fan has stopped.
• Use only original spare parts.

The cartridge only needs to be changed every 3 months. The level of the cartridge is controlled by a sensor that will warn
when the liquid runs out so that it can be replaced.
One of the technologies of the disinfection device is implemented with an ultraviolet ray emitting LED which, as it is inserted
inside the housing of the unit and uses low intensity powers, is completely harmless to humans, because its incidence is not
direct on living beings, but on the titanium dioxide coated fan.
According to UNE-EN 12198 the K7 is classied as category 0 but for the information of users and maintenance team its been
identied with category 1 label.

Electrical power supply
If the equipment is not working, the error is most likely due to an incorrect
terminal power.
1 - Check that it has been connected to a live electrical outlet.
2 - Check that the current is compatible with the equipment and that the terminal block ca-
bles are connected according to the electrical diagram specied in this manual.
3- Check that voltage (230Vx1) reaches the equipment and, if not, check the power cables.
3.1 - If the equipment has voltage, but the fan does not rotate, check if there is 5.5V in
continuous between the yellow and black cables.
3.2 - In case there is no 5.5V, check that there is 10V in continuous between the oran-
ge and black cables. If there is 10V, one of the resistors has been damaged and must
be replaced.
3.3 - If there is no 10V, the fan’s 10V signal is damaged, the fan needs to be replaced.
Filters replacements
If the equipment has a luminous red signal light on, it means that the lters are fully dirty
and must be replaced (page 10).
