DANGER!

ELECTRICITY

2 Planning and preparation work

2.1 Joiner / ﬁtter

Airﬂow

Check that the air moves from rooms with supply air

valves to rooms with extract air valves.

Kitchen

If a kitchen fan with a motor is included, sufﬁcient

supply air must be ensured. See Chap. 9.1 Installation

of external cooker hood and Chap. 9.2 Adjusting

the cooker hood for more information.

Fireplace

When using a ﬁreplace, sufﬁcient air supply from

a separate supply air point must be ensured.

Location in the building

Location of the unit on an internal wall requires

insulation of the wall, interrupted studs and boards,

and double plasterboard or a wall structure of similar

quality (see Chap. 3.4.1 Positioning requirements).

Suspension of unit

See kap. 3 Installation på side 6.

Access

The unit must have good access for service/

maintenance. See kap. 3 Installation på side 6

for details.

Fire requirements

Any ﬁre safety requirements must be clariﬁed.

Location of heat sources must be coordinated with

extraction valves, so that heat is not sucked straight

out through the valves or door gaps.

2.2 Plumber (if the unit has a water battery)

Water pipe layout and location of the water battery

(duct battery) must be planned. These must be kept

warm to avoid frost damage. A closing damper with

spring must be used. See separate instructions that

accompany the water battery.

2.3 Electrician

Power supply

The units have an approx. 2 m cable with plug and

require a single-phase earthed socket nearby. Plug

requirements: 10 A. We recommend a separate circuit

for the unit. It is important that the plug is accessible

for servicing when the unit is fully installed.

If a cooker hood is to be connected to the ventilation

unit, a minimum Ø16 conduit must be installed for the

two-core signal cable.

NB!

The PG nipple for the power cable must be tightened

with a torque of 2.0 Nm if the cable is replaced.

For exact positioning of the electrical bushings,

see 11.1 Dimensioned drawing.

The assembly instructions for the

product must be followed.

Wiring for control switches.

Ø20 conduit for running the trailing cable for

controlling the unit should be laid between the

unit and an easily accessible place in the home

(e.g. outside the bathroom) and terminated with

a ﬂush-mounted single wall box. The control switch

is located here. The control cable must be located

min. 30 cm away from any power cables. The control

cable must be max. 24 m to ensure a signal.

Control panel

The control panel is designed for ﬂush mounting over

a single wall box or surface mounting on the wall.

ﬁgure 1

Positioning of bushings for

electrical conductors.

The water battery must be

located in a room with a drain.

Positioning must accord with

individual countries' electrical

safety legislation. Check which

rules apply in your country.

3 Installation

The unit can be installed in the following ways:

• On the ceiling.

• Horizontally on a wall.

Mounting devices for this can be purchased as

an accessory.

• On the ﬂoor (lying on its back).

In this case absorption feet are recommended

(available as an accessory).

The unit comes in both a left-hand and a right-hand

version, depending on what is best with regard to duct

positioning.

ﬁgure 2

Location options

3.1 Mounting the safety strap

Mount the safety strap as shown on ﬁgure 3.

ﬁgure 3

Fixed safety strap

When the unit is located on the

ﬂoor, this strap must always be

mounted.

We also recommend its use for

ceiling mounting.

What is supplied?

3.2 What is supplied?

3.3 Ceiling mounting

3.3.1

Positioning requirements

The unit is designed to be installed in boiler rooms,

laundry rooms, stores, lofts or other suitable areas.

The unit should be positioned in such a way that there

is no danger of noise nuisance in nearby rooms.

If the unit is located in a warm room where a lot of

moisture is generated, condensation may form on the

outside of the unit during periods when the outside

temperature is low.

The base should be stable and level.

3.3.2

Space requirements

The unit must be installed with suitable space for

servicing and maintenance such as ﬁlter replacement

and cleaning of fans and recovery system.

See ﬁgure 5. The control cable with plug for

automatic control must be easily accessible when the

unit is fully installed.

These are minimum requirements and only take

service needs into account.

Opening the door in case of ceiling mounting

530mm

400mm

200mm

In the case of mounting in an

enclosure or a suspended ceiling,

remember that the door must be

able to open by 120°.

Ensure there is servicing access

to electrical bushings. See the

dimensioned drawing for exact

location.

Positioning must accord with

individual countries' electrical

safety legislation. Check which

rules apply in your country.

electrical bushings

Fixing brackets to be mounted in the same way regardless of top or side mounting

1 2

The air handling unit can be mounted in the ceiling in several different ways.

Alternative 1 - Top mounting Alternative 2 - Side mounting

To facilitate access to the ﬁxing bracket,

the polystyrene rings round the bosses

may be removed.

3.3.3

Mounting of ﬁxing bracket

Alternative 1 - Top mounting

3mm

The unit must always

be mounted at

min. 3mm distance

from the mounting

substrate, as shown in

ﬁgure 12. This is to

prevent structural

sound.

Alternative 1 - Top mounting

If it is necessary to pre-drill your mounting substrate,

the drilling pattern is given here:

Select a suitable ﬁxing device which matches your mounting

substrate.

Remember that the unit weighs 46 kg and the ﬁxing device

must be able to support this.
