– Important notes

In this user manual, especially important notes are marked as WARNING! or NOTE!

WARNING:

Warnings against hazards and errors that can cause severe or fatal injuries or can have serious
consequences for the product.

NOTE!

Useful notes and additional information.

This Installation Manual forms part of the ventilation unit and must be kept readily available at all times. For
the installer this manual must be used in conjunction with the User Manual. Both must be handed to any
technicians carrying out work on the unit and must be handed over to the new tenant when moving home.

1.1 Intended use

This ventilation unit is intended exclusively for the ventilation and exhaust ventilation of rooms within a
property. It must be installed in a frost-free interior room only.

Any other use and any use exceeding the design limits is not permitted. Any improper use can damage the
unit and can cause severe hazards.

The unit must not be altered or modified. The unit is guaranteed safe to use in accordance with these
instructions. The instructions in this Installation manual and in the corresponding User manual must be
observed.

1.2 Safety instructions

Failure to observe the safety instructions can cause hazards to the user as well as to the unit and will
invalidate the guarantee.

1.2.1 Installation

The ventilation unit must be installed by a qualified technician in accordance with this Installation manual.
The unit must be installed in a frost-free environment with good access and sufficient space for carrying out

any necessary maintenance or repair work. Two condensate hoses are required and must be correctly taken
to a drain in order to avoid any electrical hazards and any damage to the building. The unit must not be
installed where corrosive or inflammable gases can enter the unit, or where harmful pollutants can affect
people or put people at risk. All applicable fire regulations must be observed and complied with. Connecting
exhaust hoods to the ventilation unit is not permitted.

The unit must be installed by a qualified technician in compliance with all applicable standards and local
regulations, as well as in accordance with the Installation manual.

WARNING:

Before starting any work on the unit, the power supply

must be isolated in order to prevent any

electrical hazard.

Install and secure the mains cable through the cover cable gland. Ensure that the bare cable ends are correctly
and tightly secured into the mains supply terminal block.

Any setting up and programming must be carried out by a qualified technician in accordance with the
installation instructions.

1.2.2 Open Flue installations

Using the ventilation unit together with fuel burning devices (e.g. fire places, gas stoves) is subject to
special requirements.

WARNING:

It must be ensured that the unit is correctly set up so that no open flue gases are drawn back into
the room. All applicable national and regional guidelines and regulations must be observed.

Section 1

– Important notes

1.2.3 Start-up, use, interruption

The completed installation must be tested to ensure the unit works correctly. The user must read the User
manual in order to understand the procedures for use and maintenance.

WARNING:

The unit contains rotating fans. Do not put hands or fingers or any other objects into the unit or
ducting as this may cause injuries or damage to the unit.

1.2.4 Maintenance, repair, spare parts

In order to ensure continuous safe operation, the ventilation unit must be maintained regularly. Any
maintenance and repair work other than cleaning or changing filters must be carried out by a qualified
technician. Before opening the unit, turn off all associated circuits and secure against unintentional switching­on. Use only original spare parts from the manufacturer.

1.2.5 Alterations and modifications

Always consult a qualified technician if any alterations or modifications to the unit or system are required.
Structural changes to the building can also have an effect on the ventilation system: Always consult a qualified
technician.

Section

2 – Description of the Device

2.1 Purpose

The unit is designed for controlled supply and exhaust ventilation of frost-free rooms within a building.
The air flows through air ducts.
Connecting exhaust hoods to the ventilation system is not permitted. The unit is not to be used as a

dehumidifier.

2.2 Package contents

The unit is delivered with the following package contents:

• Ventilation unit with integrated control panel

• Condensate connection kit

• Installation manual and User manual

2.3 Operating principle

The unit is fitted with two fans using energy-saving “EC” technology which carries out a controlled air
exchange.

Used air is drawn in to the unit as Extracted air from the rooms with the highest air humidity and odour (e.g.
bathroom and kitchen) and is transferred to the outside as Exhaust air via a system of air ducts.

At the same time, a second duct system takes in Fresh air from outside the building and transfers it into living
rooms and bedrooms as Supply air.

Both air flows are completely separate and are passed through a heat exchanger which recovers the waste
heat from the extracted air to warm up the supply air. This ensures that the majority of heat energy is kept in
the building.

An internal bypass can be opened so that fresh air is supplied to the intake rooms without being warmed up
by the heat exchanger. Heat recovery is disabled in this case.

2 – Description of the Device

Fig. 2.1 Supply-air/extract-air system with heat recovery

1 Fresh air* 6 Air diffuser NOTE!

* Outside installation points for the Fresh Air intake
(1) and the Exhaust Air outlet (4) MUST be
sufficiently far enough apart to prevent the exhaust
air being drawn into the property through the Fresh
air duct. (No “re-circulation”).

2 Supply air 7 Air transfer opening
3 Extract air A Supply-air area
4 Exhaust air* B Extract-air area
5 Ventilation unit C Air transfer area

Halls and corridors normally act as transfer areas in which the air from the supply areas flows into the extract
areas. Undercut doors and air transfer grilles are used so that the air flow between rooms is not restricted.

Where fitted, a radial air-duct system with direct pipe routes between air diffusers and supply air/extract air
valves:

• Simplifies the balancing of volume flow rates and pressures

• Prevents sound transmitting from adjacent rooms

• Makes cleaning easier, due to direct pipe routes

2.4 System Design

The ventilation system must be properly designed by a qualified ventilation engineer so that it meets the
requirements of the building.

The plan will determine :

• The location of the Supply air inlets (Low pollution: Usually living rooms, bedrooms, recreation rooms,
offices, etc)

• The location of the Extract air outlets (Higher pollution: Usually bathrooms, toilets, kitchens, utility rooms,
etc)

• The requirement for any undercut doors and air transfer grilles. (Usually Halls and corridors, etc)

• The overall required Supply flow rate

• The overall required Extract flow rate

• Supply and Extract flow rates into individual rooms

Section

2 – Description of the Device

(Devices such as grilles or diffuser or dampers can be used to set individual room rates)

NOTE!

See Table 3.1 on Page 7 for Factory set Supply and Extract flow rates.
See Section 6.3 Installer menu – Set the Air flow for any flow rates need to be changed. (As
determined by the design).

NOTE!

The following documents are needed for correct designin

g of the system:

• Details of the building and the rooms or areas to be ventilated.

• Floor plans indicating room use.

• Sectional drawing indicating room heights.

NOTE!

An incorrectly specified system can lead to insufficient ventilation and can cause high noise levels
and an excessive energy consumption.
Any applicable guidelines and regulations must be observed and complied with.

WARNING:

Using the ventilation unit together with open flue fuel burning devices (e.g. fireplaces, gas stoves) is
subject to further special requirements.
Any applicable national as well as regional guidelines and regulations must be observed.
We strongly recommend you consult a qualified specialist.

WARNING:

Applicable fire regulations must be complied with. For example, fire dampers should be fitted,
where required.
