EEC, 86/188/EEC, 92/58/EEC and 92/57/EEC which each employer has the obligation to respect and to have respected. The units have been designed and built according to the current state of the art and the technical rules in force. The laws, provisions, prescriptions, ordinances, directives in force for these machines have been complied with. The materials used and the parts of the equipment, as well as the production, quality assurance and control processes meet the highest demands for safety and reliability. By using them for the purposes specified in this user manual, operating them with due diligence and carrying out accurate maintenance and state-of-the-art overhauls, continuous and long-lasting performance and functionality of the units can be maintained.
INTERVENTIONS AND MAINTENANCE
The user manual can never replace adequate user experience; for some particularly demanding maintenance operations, this manual is a reminder of the main activities to be carried out for operators with specific training acquired, for example, by attending training courses at the manufacturer. Read the following tips carefully:
- Constant and accurate preventive maintenance always guarantees the high operational safety of the unit. Never postpone necessary repairs and have them carried out only and exclusively by specialized personnel, using only original spare parts;
- The operator’s workplace must be kept clean, tidy and free from objects that may restrict free movement.
- Operators must avoid clumsy operations, in awkward positions that can compromise their balance.
- The workplace must be adequately lit for the foreseen operations. Insufficient or excessive lighting can lead to risks.
- Any intervention on the unit must be carried out by qualified personnel;
- Before carrying out any intervention or maintenance on the unit, make sure you have cut off the power supply;
- Make sure that the safety devices work correctly and that there are no doubts about their operation; otherwise, do not start the unit under any circumstances;
- Use only tools prescribed by the manufacturer of the unit. To avoid personal injury, do not use worn or damaged, low-quality or improvised tools;
- This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities or lack of experience and knowledge, unless they have been given supervision or instructions relating to use of the appliance by of a person responsible for their safety
- children must be supervised to ensure that they do not play with the appliance
- precautions must be taken to avoid the backflow of gas into the room from the open gas flue or other combustible appliances
- once the unit has been cleaned, the operator must check that there are no worn or damaged parts or parts that are not firmly fixed, otherwise ask for the intervention of the maintenance technician;
- The use of flammable fluids in cleaning operations is prohibited.
Do not use diesel, petrol or solvents to clean the unit as the former leave an oily film which favors the adhesion of dust, while solvents (even if weak) damage the paint and therefore favor the formation of rust. If a jet of water enters electrical equipment, in addition to oxidizing the contacts, it may cause malfunction of the unit. For this reason, do not use jets of water or steam on sensors, connectors or any electrical part.

PRODUCT DESCRIPTION
KERS+ recovery are designed to ventilate apartments, hotels, bars and any other civil, residential and commercial environment in a controlled way. The unit is equipped with a very high efficiency ceramic heat exchanger which allows fresh air to be introduced into the room and heat to be recovered from the previously expelled exhaust air. The KERS+ recovery combine cutting-edge technical solutions with a pleasant aesthetic, thanks to the elegant external covers. KERS+ is designed to be mounted in external walls with a thickness of 280 mm to 500 mm. Special extensions allow greater thicknesses to be overcome (see paragraph: DUCT FOR THICK WALLS). The low speed of the air avoids the annoying drafts of traditional air conditioning systems and guarantees maximum environmental comfort. The exclusive use of top-quality parts in the aeraulic and electrical parts puts the KERS+ units at the highest levels of the state of the art, in terms of efficiency, reliability and sound power emitted. KERS+ is equipped with an automatic anti-wind damper as required by the CE 13141-8 Standard
STRUCTURE AND OPERATION
The unit is made up of: an internal unit, a central body, an external hood and a duct with insulation. The internal unit presides over the operation, the central body contains the exchanger, the fan and the filters, the external hood protects from the rain. The two filters and the central body are inserted in the duct. The filters purify the new air and prevent the entry, from the outside, of objects that could damage the exchanger or fan. The unit is equipped with a non-volatile memory clock, which signals the opportunity to check the filters every 2000 hours of operation, with the lighting of a LED, located on the left side of the unit. Once the filters have been replaced and the controller reset, the LED will remain off until another 2000 hours of operation have elapsed. The hexagonal cell heat exchanger recovers the heat from the exhausted air, to heat the air introduced into the room. A shutter closes automatically when the appliance is in stand-by, to prevent unwanted drafts. The ventilation unit must be installed in places where it is not possible for water or other substances to enter which could damage its components.
KERS+ (in models 50 and 25) can work in different modes:
- Extraction: the unit operates permanently in extraction mode.
- Input: the unit operates permanently in input.
- Home mode: the unit operates alternately in two phases of approximately 60 seconds each:
- Night time mode: if activated, the speed is reduced to the “Super minimum” level so that the air exchange continues, without producing noise. The pre-set ventilation is automatically reactivated as the brightness increases.
- Humidity mode: if activated, the ventilation rises to the maximum level, as long as the ambient humidity remains higher than the set value.
OPERATIONAL LIMITS
- The recovery unit must be used with temperatures between -20° and +40°, with relative humidity lower than 97%.
- If installed in poorly lit locations, the “night” mode may not be usable.
MODELS
- The recovery units are produced in two models, one with a max flow rate of 50 m3/h, the other with a max flow rate of 25 m3/h, which can be inserted respectively in holes in the walls of 162 mm and 102 mm.
OPERATION OF SEVERAL DEVICES
OPERATION OF SEVERAL DEVICES CONNECTED TO EACH OTHER
When several appliances are installed in a single room, their operation must be synchronized so as not to put pressure or depression in the room. The appliances must be connected in cascade to each other (see specific chapter), so that when half of them work in extraction (phase 1), the other half work in injection (phase 2). With cascade connection, a single remote control, which operates on the first device, called “Master”, is sufficient to manage all the other “Slaves”. Appliances operating in different rooms can also be connected in cascade, provided that they have similar needs and it is useful to manage them with a single command. The maximum number of recuperators that can be connected in cascade is ten pieces.
ELECTRICAL CIRCUITS
ELECTRICAL EQUIPMENT
- All electrical and electronic equipment is made and wired in compliance with low voltage and electromagnetic compatibility standards for domestic use applications.
- The fans, equipped with low consumption reversible EC motors with adjustable flow rate, are extremely silent. Once the fan has been installed in the suitably prepared hole (see paragraph 9.4), connect an electrical outlet (220-240 Vac- 50 Hz).
BUTTONS AND REMOTE CONTROL
BUTTONS AND REMOTE CONTROL FOR UNIT MANAGEMENT
- The unit can be controlled with buttons located on the fan or with a remote control.
BUTTONS ON BOARD THE MACHINE
- The on-board buttons are located on the left side of the device, they are touch-sensitive: just place your finger to control them.
- If several devices connected in cascade are installed, only the first (master) accepts the commands, whether they come from the buttons on the machine or from the remote control.
- All other devices (slaves) are controlled by the master.

|
· Led off : The device works independently or is a MASTER, it can be controlled by remote control or from the device board.
· LED on : this recovery unit is a SLAVE, therefore it does not accept direct commands, but the commands must be applied to the relative Master
· Flashing LED : following receipt of a command, the device signals its refusal, because it is commanded by a Master device or because an external controller is commanding it.
REMOTE CONTROL
The operating distance of the remote control can be influenced by the environment in which it operates. Possible operations:
Key | Description | Function |
---|---|---|
ON/OFF | · The button turns the unit on and off | |
Home mode
| · Activates heat recovery mode with alternating 60 second extract and supply cycles
· Return the device to manual home mode
· Any fill-only, extract-only or extract boost mode are disabled
DAMPER OPENING
A damper closes automatically when the recovery unit is not in operation. When the appliance is switched on, the damper opens and the fan waits for it to be opened. The LED relating to the selected speed flashes for the time required for the shutter to open. Then it becomes fixed and the fan starts.
REMOTE COMMAND
When the remote-control contact is closed, Kers+ does not accept commands from the remote control and from the machine. The active remote control is signaled by an orange minimum speed LED and a white average speed LED. When the device receives the command, heat recovery is active at medium speed. When the device is not receiving the command, it switches off, from that moment it is possible to control it manually from the buttons on the machine or from the remote control by pressing the On/Off button twice. If the remote control is reactivated, it will take precedence over any previous setting.

Warnings
-
There is a risk of the grille falling out during installation. Make sure that this eventuality does not cause damage to people or things, possibly cordoning off the area outside.
-
The grill supplied with the appliance must not be used if you opt for the flexible grills.
Installation of the flexible external grille
Slightly flex the grate and slide it into the duct. Holding it firmly by the center peg, push it completely out of the duct so it can expand and return to its original shape. Pull towards you and at the same time rotate the grill counterclockwise. The springs retract into the duct and adhere to the wall, and lock the grate in place.
Roll up the insulation and insert it a first time inside the duct up to the stop. Measure the distance that separates the insulation from the entrance to the duct: it must be at least 28 cm. If it is less, extract the insulation and cut off the excess. Insert the insulation back into the duct. Insert the central body of the device, which must abut without pushing the grille out.
THICK WALL DUCT
- If the wall thickness is greater than the length of the normal duct supplied with the appliance (50cm), an 80cm duct is available.
