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 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.

• 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 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.

3.4 Space required

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 (§ 7.2 - Installer menu: 3 Machine Orientation).

• Move the F7 lter 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

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.

WARNING

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

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 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 (§ 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 speciﬁc warnings and cautions in Chapter 2 “Precautions” are carefully read, understood and applied!

5.a Prepare the surface where the unit is to be mounted. Make sure that the surface is at, levelled and that it supports the

weight of the unit. 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 § 5.4. Check that it starts up correctly.

5.4 Precabled electric connections

The unit must be earthed.

The units are wired internally from factory.

To connect the the CTRL-DSP to the mother board use a 4 poles twisted-pair cable: 30m max length.

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 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.
