2 PRECAUTIONS
WARNING
Make sure that the mains supply to the unit is disconnected before performing any installation, service, maintenance or electrical work!
WARNING
The installation and service of the unit and complete ventilation system must be performed by an authorized installer and in accordance with local rules and
regulations.
TRANSPORT AND STORAGE
• Do not leave the device exposed to atmospheric agents (rain, sun, snow, etc.).
• Duct connections/duct ends must be covered during storage and installation
INSTALLATION
• After removing the product from its packaging, verify its conditions. Do not leave packaging within the reach of children or people with disabilities.
• Beware of sharp edges. Use protective gloves.
• The device should not be used as an activator for water heaters, stoves, etc., nor should it discharge into hot air/fume vent ducts deriving from any type of
combustion unit or tumble dryer. It must expel air outside via its own special duct.
• If the environment in which the product is installed also houses a fuel-operating device (water heater, methane stove etc., that is not a “sealed chamber”
type), it is essential to ensure adequate air intake, to ensure good combustion and proper equipment operation.
• The electrical system to which the device is connected must comply with local regulations.
• Before connecting the product to the power supply or the power outlet, ensure that:
- the data plate (voltage and frequency) correspond to those of the electrical mains
- the electrical power supply/socket is adequate for maximum device power
• For installation an omnipolar switch should be incorporated in the xed wiring, in accordance with the wiring rules, to provide a full disconnection under
overvoltage category III conditions (contact opening distance equal to or greater than 3mm).
USE
• The device should not be used for applications other than those specied in this manual.
• The device is not intended for use by persons (including children) with reduced physical, sensory or mental capacities or those with a lack of experience and
knowledge, unless they have been given supervision or instruction concerning use of the device from a person responsible for their safety. Children should
be supervised to ensure that they do not play with the device.
• Do not touch the appliance with wet or damp hands/feet.
• The device is designed to extract clean air only, i.e. without grease, soot, chemical or corrosive agents, or ammable or explosive mixtures.
• Do not use the product in the presence of inammable vapours, such as alcohol, insecticides, gasoline, etc.
• The system should operate continuously, and only be stopped for maintenance/service.
• Do not obstruct ducts or grilles to ensure optimum air passage.
• Do not immerse the device or its parts in water or other liquids.
• Operating temperature: 0°C up to +40 °C.
SERVICE
• Although the mains supply to the unit has been disconnected there is still risk for injury due to rotating parts that have not come to a complete standstill.
• Beware of sharp edges. Use protective gloves.
• Use original spare parts only for repairs.

4 TRANSPORT AND STORAGE
The appliance is delivered in one carton box.
The appliance should be stored and transported in such a way that it is protected against physical damage that can harm spigots, casing etc.
It should be covered so that dust, rain and snow cannot enter and damage the unit and its components.
5 INSTALLATION
This section describes how to install the unit correctly.
The unit must be installed according to these instructions.
5.1 Unpacking
Verify that the unit (and eventual accessories) delivered is according to order before starting the installation. Any discrepancies from the ordered equipment
must be reported to the supplier.
5.2 Where/how to install
• All QR units are meant for indoor installation in a heated space.
• Mount the unit on flat surface (wall).
• The unit must always be installed vertically.
• It’s important that the unit is completely leveled before it is put into operation.
• Place the unit preferably in a separate room (e.g. storage, laundry room or similar).
• When choosing the location it should be kept in mind that the unit requires maintenance regularly and that the inspection doors should be easily accessible.
• Leave free space for opening the removable panels and for removal of the main components (see 3.4).
• The outdoor air grilles if possible be put in the northern or eastern side of the building and away from other exhaust outlets like kitchen fan exhausts or
laundry room outlets.
5.3 Installation
The unit must be installed in the following position.
It is important that the unit is vertical in order for the condensation drainage to work properly.
WARNING
Make sure that specic warnings and cautions in Chapter 2 “Precautions” are carefully read, understood and applied!

6 COMMISSIONING
6.1 Setting Fan speed
The speed of the unit can be adjusted during installation according to required ventilation rate.
Figure 6.a below shows performance curves (for supply air and extract air) at different settings of the 0-10V signal to the motors. Airow and consumption
refer to one single motor.
Table 6.b indicates the efficiency of the heat exchanger and of the condensation produced in different climatic conditions, to help the installer or the designer
of the ventilation system to decide if to connect one or both condensation drainages.
High production of condensation is the direct consequence of a high efficiency level as well as of the humidity rate.
Table 6.c indicates the sound level at the different speed.

Wiring diagram: Fig.5.k – Dip switch conguration: X011 (Fig. 5.p)
7.5 Three speed operation with CTRL-S controller (accessory on request)
The unit runs at the speed selected by activating the two-position switches “S1”, “S2” and “S3” of the CTRL-S (accessory Fig. 5.r)
Speed 1 is set by turning the integral trimmer “V1” in the terminal box.
Speed 2 is set by turning the integral trimmer “V2” in the terminal box.
Speed 3 is the maximum speed achievable by the unit.
S3 switch allows to activate the bypass, so to mitigate the heat exchange when necessary - see 7.7.

8.2 Description of Components
Fans
The fans have external rotor motors of EC type which can be steplessly controlled individually between 10–100%. The motor bearings are life time lubricated
and maintenance free. It is possible to easily disconnect and replace the fans if necessary.
Filters
The filters are of filter quality G4 for both the supply air and extract air filter. The filters need to be cleaned regularly (and replaced when polluted) during
maintenance. New sets of filters can be acquired from your installer or wholesaler.
Heat exchanger
The unit is equipped with a highly efcient, counter-ow plate heat exchanger. Supply air temperature is therefore normally maintained without adding
additional heat. The heat exchanger is removable for cleaning and maintenance during service.
Condensation drainage
Depending on the relative humidity in the extract air, condensation may occur on the cold surfaces of the heat exchanger, on one side in winter time, on the
7.6 Anti-frost functionality
The unit is equipped with a thermostat which, when necessary, reduces the speed of the intake fan to prevent the freezing of the heat exchanger, which could
get damaged irreparably.
7.7 Bypass functionality
The QR350MBP is equipped with a physical bypass which allows to mitigate the heat exchange when the indoor and outdoor temperature combinates are
such that the heat exchange is not recommended.
Bypass can be activated through a dedicated switch (see Fig. 5.j to 5.n), or via the relevant switch integrated into the CTRL-S (Fig.5.o)
