or parts that are not solidly fixed, otherwise request the intervention of the maintenance technician;
- The use of flammable fluids in cleaning operations is prohibited.
For cleaning the unit do not use diesel, petroleum or solvents as the former leave an oily patina that promotes
the adhesion of dust, while the solvents (even if weak) damage the paint and thus promote the formation of rust.
If a jet of water penetrates electrical equipment as well as inducing oxidation of the contacts, it can cause the
unit to malfunction. Therefore, do not use jets of water or steam on sensors, connectors or any electrical part.
11.5 INTENDED USE
The KERS units are point heat recovery units (room by room), to be installed on the wall, which allow to ventilate
a room without ducts and without dispersing heat with the emission of exhausted air.
Its use is recommended within the operating limits indicated in this manual.
Place the unit in environments where there is no danger of explosion, corrosion, fire and where there
are vibrations and electromagnetic fields. It is also forbidden to operate in a different way from what is
indicated or to neglect operations necessary for safety.

12. PRODUCT DESCRIPTION
KERS recuperators are designed to ventilate apartments, hotels, bars and any other civil, residential and
commercial environment in a controlled manner.
The unit is equipped with a ceramic exchanger with very high efficiency that allows to introduce fresh air into
the environment and to recover heat from the exhaust air previously expelled.
KERS recuperators combine state-of-the-art technical solutions (ceramic core with 97% efficiency) with an
attractive appearance, thanks to the elegant external covers.
KERS is designed to be mounted in exterior walls with thickness from 250 mm to 500 mm.
The low air speed avoids the annoying draughts of traditional air conditioning systems and ensures maximum
environmental comfort.
The use of top-quality components in the aeraulic and electrical parts puts KERS units at the highest level of the
state of the art, in terms of efficiency, reliability and sound power output.
12.2 STRUCTURE AND OPERATION
The unit consists of: a ventilation unit, a recuperator, two filters, a duct, an external noise protection hood.
Conduit and exterior insulation can be cut to wall size.
The two filters and the central body are inserted into the duct. The filters purify the new air and prevent objects
from entering from the outside that could damage the exchanger or fan.
The unit is equipped with a non-volatile memory clock, which signals after 3000 hours of operation the need to
check the filters, with the lighting of an LED, placed in transparency on the front. Once the filters have been
replaced, the LED turns off with the appropriate button on the remote control.
The heat exchanger, made of ceramic material, recovers the heat from the exhaust air and heats the air supplied
to the room.
The front panel closes automatically when the unit is in stand-by mode to prevent unwanted drafts from passing
through. (Closing time about 40 seconds)
The ventilation unit must be installed in a location where water or other substances cannot enter and damage
its components.
KERS evo operates according to the following modes:
Ventilation: the unit operates continuously in extraction.
Supply/Extract: The unit operates permanently in supply/extract mode.
Heat recovery: the unit operates alternately in two phases of approximately 65 seconds each:

KERS 50 Evo e KERS 25 Evo –user and installer manual - EN
Pag. 26 di 40
Step 1 - stale warm air is extracted from the room. As it flows through the ceramic heat exchanger, it
warms it up. It thus transfers up to 97% of the heat energy. In about 65 seconds the exchanger is heated
and the unit switches to phase 2.
Step 2 - fresh air flows in from outside through the ceramic exchanger which releases heat to the air up
to room temperature. In about 65 seconds the ceramic heat exchanger cools down and the unit switches
to "phase 1".
12.3 TWILIGHT AND HUMIDITY SENSORS
A humidity sensor activates ventilation when the ambient humidity exceeds the desired value. A red LED on KERS
indicates that the set limit has been exceeded. A twilight sensor reduces nighttime noise to an undetectable
level (see using the remote control).
12.4 OPERATIONAL LIMITS
The fan should be used for indoor applications, with room temperatures between -30° and +50°, and relative
humidity less than 97%.
13. OPERATION OF SEVERAL INTERCONNECTED DEVICES
When more than one appliance is installed in a single room, it is useful to synchronize their operation so as not to
put the room under pressure or vacuum. The devices must be connected in series with each other (see chapter:
electrical connections), so that when one half of them works in extraction (phase 1), the other half works in supply
(phase 2), and vice versa.
With series connection, a single remote control, operating on the first device, called "Master", is sufficient to
control all installed KERS evo. All other devices connected in series do not respond to the remote control.
14. ELECTRICAL CIRCUITS
14.2 ELECTRICAL EQUIPMENT
The electrical panel is realized and wired according to low voltage and electromagnetic compatibility
regulations.

EN KERS 50 Evo e KERS 25 Evo –user and installer manual
Pag. 27 di 40
The fans, equipped with energy-efficient, reversible EC motors, are extremely quiet.
14.3 WIRING DIAGRAMS
The unit is built to operate on 230V/50Hz single-phase AC.
Use copper cables with a cross-section of between 0.5 mm² and 0.75 mm² for the power supply to the unit. Insert
upstream a circuit breaker with a passage current higher than that required by a device (see technical data
table).
The connection terminal block is protected by a transparent cover, as shown in the figure. To access the terminal
block, make sure there is no power supply and remove the cover held in place by a screw,

MASTER (Input - Output)
SLAVE (Extraction - Input)
SLAVE (Input - Output)
The first KERS Evo (master) unit controls all others. The units must be set up so that injections and extractions are
not simultaneous, so as not to put the environment under pressure or depression.
A set of dip-switches, located under the protective cap, allows the operation of the recuperators to be
programmed correctly.
When several KERS Evo are connected in series, all of them are managed by the first one (master) and its
remote control. In addition to the wiring, performed as per the wiring diagram, it is necessary to program
the recuperators with the correct positioning of the dip-switches. Other (slave) units do not respond to the
remote control.

Proper operation of the unit requires that filters be cleaned regularly or replaced when worn. It is also necessary
to clean the fan impeller and ceramic heat exchanger from any dust that may settle over time.

KERS 50 Evo e KERS 25 Evo –user and installer manual - EN
Pag. 32 di 40
Extraction of ceramic exchanger and filters
-Slightly rotate the guard grille counterclockwise to release the exchanger.
-Pull out the body of the appliance using the supplied cord. Remove the filters from the body.
Cleaning filters
Clean filters as needed, but no less than once every three months. A red LED on board the unit lights up after
3000 hours of operation to remind you to perform cleaning. Filters should only be reinserted when completely
dry. You can also clean the filters with a vacuum cleaner. The life of the filters, thus maintained, is about three
years. To reset the filter cleaning timer, press the appropriate button on the remote control.
Cleaning the ceramic exchanger
Dust may accumulate on the ceramic exchanger over time, even with regular filter maintenance. Also clean
the ceramic heat exchanger to ensure high efficiency of energy recovery. A vacuum cleaner is recommended
for this operation.
Replacing the remote-control battery (if necessary)
If your device stops responding to the remote, you may need to replace the battery: gently slide the battery
case on the back of the remote, you can help with a screwdriver. The battery is CR2032type
Checking and cleaning the external grill
The outer hood may over time become clogged with leaves, gnats or other objects that would reduce the
airflow rate and therefore the performance of the device. Check the outside grill for clog-free condition at least
twice a year and clean as needed.
