Heat & Coolth Recovery
Read this manual carefully before using the product and keep it in a
safe place for reference.
This product was constructed up to standard and in compliance with regulations
relating to electrical equipment and must be installed by technically qualified
personnel. The manufacturer assumes no responsibility for damage to persons or
property resulting from failure to observe the regulations contained in this booklet.
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
• Aer 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).
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 mains supply and contact a
qualified technician immediately.

2.
Use
• The device should not be used for applications other than those specified in this manual.
• This appliance can be used by children aged from 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 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 vapours, such as alcohol, insecticides, gasoline, etc.
• MVHR systems are generally designed to operate continuously.
• Only turn offthe power supply tothe unitwhenevera malfunctionis detectedor in the case ofinspection,cleaningormaintenance.Prolonged
and/orrepeatedpowerinterruptiontotheunit(anyperiodmorethan72hours)cancreateahealthandsafetyhazard,damagecomponentsand
will invalidate any warranty.
• Do not obstruct ducts or grilles to ensure optimum air passage.
• Do not immerse the device or its parts in water or other liquids.
• Only turn off the power supply to the unit whenever a malfunction is detected or in the case of inspection, cleaning or maintenance.
Prolonged and/or repeated power interruption to the unit (any period more than 72 hours) can create a health and safety hazard, damage
components and will invalidate any warranty.
• 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.

INSTALLATION
This section describes how to install the unit correctly. The unit must be installed according to these instructions.
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.
Where/how to install
• VIGO units work best when installed inside the bulding envelope, due to the VIGO’s insulated construction they can be installed
in loft spaces and outbuildings.
• 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 (page 3).
• 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.
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.

Perform the installation in accordance with local rules and regulations. Use the wall fixing bracket as template to indicate where to drill the holes
in the wall: make sure it is at spirit level. Use appropriate screws and wall plugs (not supplied) to fix the wall fixing bracket.
5.b Fix the 2 spacers on the back of the unit.
5.c Hook the unit at its bracket.
5.d Make sure it is at spirit level and fix it by means of the safety screw.
5.e Connect the condensation drain joints (G 3/4” M) placed in the bottom side of the unit to a U-bend (or similar) on the condensation drainage
pipe. In case close the non-used joint by means of the supplied drain stopper. Make sure this operation is well done in accordance to the best
practice in order to assure water and air tightness.
5.f Connect the unit to the duct system. Make sure that all necessary accessories are used to create a functional ventilation solution.
Connect the unit electrically according to page 7. Check that it starts up correctly.

COMMISSIONING
Setting Fan speed
The speed of the unit can be adjusted during installation according to required ventilation rate.
Figure 6.a below shows 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.
