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.
WARNING
If any abnormality in operation is detected, disconnect the device from the
main supply and contact a qualified technician immediately.
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 fixed 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 specified in this manual.
- This appliance can be used by children aged 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning the use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.
- 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 flammable or explosive mixtures.
- Do not use the product in the presence of inflammable vapors, 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 a risk of 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.

COMMISSIONING
6.1 Setting Fan speed
The speed of the unit can be adjusted during installation according to the
required ventilation rate, by setting the relevant dip switch.
Figure 6. below shows the performance curve at different settings of the 0-10V
signal to the motors. Consumption refers to the 2 motors.
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 speeds.

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 lifetime
lubricated and maintenance-free. It is possible to easily disconnect and
replace the fans if necessary.
Filters
The 2 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 efficient, counter-flow 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 the winter time, on
the other side in summer time (Table 6. b).
The condensate water is led out through a drainage pipe.
Thermistor
Temperature probe to implement temperature-dependent functions.
8.3 Maintenance
WARNING
Make sure that the mains supply to the unit is disconnected before performing
any installation, service, maintenance or electrical work!
- Keep the unit surface free from dust.
- Once every 3 months (fixed period), the unit warns the user to perform the filter maintenance (Fig. 7.b – ). The actual need to perform this operation may vary depending on indoor and outdoor ambient conditions.
- Clean the filters every 3 months with a vacuum cleaner (Fig. 8.b-c-d).
- Press the CTRL-V button (Fig. 7.b) to reactivate the filter alarm.
- Replace the filters every year.
8.4 Service
