Heat Recovery Ventilation Unit

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 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.

• 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 ﬂammable or explosive mixtures.

• Do not use the product in the presence of inﬂammable 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.

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.

Make sure that enough space is left around the unit to allow easy maintenance (access to ﬁlters, terminal box and removal of the side and front inspection panels).

To set the RIGHT orientation of the machine:

• Modify the orientation on the CTRL-DSP (point 7.2 - Installer menu: 3 Machine Orientation).

• Move the F7 ﬁlter from the left to the right side.

• Replace the ducting connection label on the top of the casing and the water drainage label on the bottom of the casing with those supplied with this

installation manual.

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, display 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

• VIGO Units work best when installed inside the building envelope, due to the VIGO’s insulated construction it 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 (see 3.4).

• The outdoor air grilles if possible are to 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.

WARNING

Make sure that speciﬁc warnings and cautions in Chapter 2 “Precautions” are carefully read, understood and applied!

Make sure that speciﬁc warnings and cautions in Chapter 2 “Precautions” are carefully read, understood and applied!

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.

Individual ‘dry traps’ must be used for each condensate drain on the MVHR. Condensation elbows have an outside diameter of 16mm.

5.a Prepare the surface where the unit is to be mounted. Make sure that the surface is ﬂat, leveled and that it supports the weight of the unit. Perform the

installation in accordance with local rules and regulations.

5.b 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.c Hook the unit at its bracket and ﬁx it by means of the safety screw.

5.d Connect the supplied condensation elbow(s) to the drainage hole(s) in the opening at the bottom of the unit: in case close and seal the non-used hole

with the 2 supplied plugs (one each side of the hole). Make sure of water and air tightness of all connections. It is necessary to use a dry trap (or similar)

in the condensation drainage pipe. The water drainage connections can be made either through the holes at the bottom side of the casing or through the

opening at the rear side of the casing.

5.e Connect the unit to the duct system. Make sure that all necessary accessories are used to create a functional ventilation solution.

5.f Connect the unit electrically according to point 5.4. Check that it starts up correctly.

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. Airﬂow 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.

Table 6.b Thermal efﬁciency of the heat exchanger and average production of condensation water. Data supplied by the manufacturer of the heat exchanger.

The heat exchanger is tested at the University of Luzern (Hochschule Lezern).
