Application

Airﬂows

The air in the home should be changed at a

continuous and sufﬁcient rate to ensure a pleas-

ant indoor climate and avoid damage to building

elements caused by dampness� The ventilation

unit should be stopped only while service work

is in progress�

The airﬂow from the ventilation unit can be

controlled to generate the various airﬂows from

a Premium control panel or a Premium cooker

hood�

•Away = a low airﬂow, which can be used

when no one is present in the home�

•Home = normal airﬂow�

•Boost = a high airﬂow, used in connection

with cooking, taking a sauna bath, showering,

drying laundry and similar activities�

On the models with electric reheating, the

Away/Home operating modes and the supply air

temperature can be controlled with the ventila-

tion unit’s built-in weekly timer; however the op-

erating mode can always be changed from the

Premium control panel or the Premium cooker

hood�

A low airﬂow when the home is unoccupied

means economical operation� This saves on fan

energy and the home heating system does not

have to heat as much air during the cold season�

The most important function of the ventila-

tion system is to ensure that the indoor air

will be continuously fresh and to remove

impurities and moisture from the air. You

should therefore make an appraisal of

whether a low airﬂow is sufﬁcient while

the home is unoccupied. The low airﬂow

mode must absolutely not be used when

someone is in the home.

To ensure that the ventilation unit is used in

the right way, you should equip the system

with a humidity sensor, if you have begun

using the Away mode.

If the load on the home is greater than

you’ve anticipated, then you should increase

the normal airﬂow to a correspondingly

higher rate.

Drying laundry

A tumbler dryer of extract air type or a drying

cabinet must not be connected to the system

due to the high moisture content in the air leav-

ing them� We recommend a condensing tumbler

dryer without duct connection�

Freeze protection

During periods of cold weather, the heat ex-

changer is liable to freeze if the extract air is

humid� A protective function then automatically

reduces the speed of the supply air fan� Under

such conditions, variations in the fan speed are

therefore normal�

Filters

The ventilation unit must not be operated with-

out ﬁlters� Use only ﬁlters recommended by

Swegon in the ventilation unit�

Commissioning

The settings of the airﬂows for the Home, Away

and Boost modes should be entered according to

the instructions so that the ventilation unit will

operate correctly� The ventilation should not be

commissioned until all work that produces large

quantities of grinding dust or other impurities

has been completed�

When the power is switched on, the ventilation unit starts

up in the Home operating mode� The start time is approx� 1

minute� After that, the control panel can be used� Likewise af-

ter a power failure, the ventilation unit starts up in the Home

operating mode, if the power failure has cleared the memory�

The functions of the push buttons are described in the image

to the right�

Fireplace switch function

The ﬁreplace function is not displayed as standard, but must

be activated from the service menu� The speed of the extract

air fan decreases and the speed of the supply air fan increases

for a few minutes� This produces excess pressure in the home

and in this way "creates" an updraught in the chimney, which

prevents smoke from entering the room when you light the

log-ﬁre�

Selection of fan speed

The fans inside the unit can be controlled to operate at three

speeds: Away/Home/Boost� Select the required fan speed from

the control panel�

Timer-controlled airflow boost is available�

The operating mode can be manually changed, even when the

fan speed is controlled by the weekly timer�

Menu/Installation and service

You can enter settings that affect the operation and functions

of the ventilation unit from the Installation and service menu

and submenu� You should normally enter these settings when

you install the ventilation system� The settings are described in

Sections 3�5 and 3�6�

Signal lamp

Selectable functions

The control panel of the cooker hood has three pushbuttons�

Besides switching the cooker hood’s lighting on and off, two

control functions can be set as follows:

• Fan speed. The fans in the ventilation unit have three

speeds: away, home and boost� The period for operation

in the boosted speed mode is preset to 60 minutes, after

which the ventilation unit fans will decelerate to normal

speed�

• The shut-off damper of the cooker hood. When prepar-

ing food or carrying out a similar activity, a 30, 60 or 120

minute damper-open period can be selected�

1.1 General

The ventilation unit can be installed in a scullery, storage

space, etc� The temperature in the installation space must be

constantly more than +10 °C�

The ventilation unit conforms to enclosure class IP 44 when

the cover is closed�

Connect the extract air from the Premium cooker hood via a

duct to the extra duct connection spigot on the top side of the

ventilation unit�

The ventilation unit can be installed as a wall cabinet above

the cooker� The Premium cooker hood can be connected

directly to the duct connection spigot on the underside of the

ventilation unit�

Superﬂuous connections should be blanked off with lids�

To make it easier to lift the ventilation unit, the inspection

cover can be removed and the heat exchanger can be disman-

tled from the unit� The fans can also be removed if necessary�

See Section 4, Service�

1.2 To install the ventilation unit

Secure the ventilation unit to the wall using the wall mounting

bracket supplied with the unit�

The ventilation unit should not be secured to a wall that

borders to a living room or a bedroom.

If the wall is composed of vertical studs and building boards,

the wall must be reinforced with horizontal studs to enable it

to support the weight of the unit�

Swegon also recommends that the wall be insulated with

mineral wool or similar insulation for preventing sound from

propagating to other rooms�

Secure the mounting bracket horizontally to the wall with

screws, using a suitable means of anchoring that can support

the weight of the ventilation unit�

Lift the ventilation unit into place, so that the wall bracket tips

engage into the corresponding slots on the backside of the

ventilation unit�

Make sure that the electric and control cables are acces-

sible. See also Section 1.6 Electric and control cables.

The ventilation unit can also be mounted in a mounting frame

on the ceiling� See Optional equipment�

1.3 Condensate discharge

As a rule, no condensate discharge is needed under dry ambi-

ent conditions and in combination with a rotary heat exchang-

er� A certain humidity load exists in homes and a condensate

discharge line should be connected to the ventilation unit, if

considerable moisture is produced in the home�

Connect the condensate discharge hose to the condensate

discharge connection of the unit (3/8”, Male threads)� The

condensate must be channelled to a ﬂoor gulley, the water

trap of a sink or the equivalent by means of a stiff hose or a

pipe having an inner diameter of at least 12 mm� The water

must not be led away directly to the sewer�

Vertically mount the water trap on the hose supplied with the

unit and ﬁll it with water� The hose must not have a second

water trap or be run horizontally� The damming height of the

water trap should be at least 100 mm�

The bypass for the kitchen is intended for

use when the airﬂows from the cooker hood/

kitchen are boosted. The kitchen’s extract air

should be conducted via the extract air duct.

If the extract air is continuously conducted via

the cooker hood, the balance between supply

air and extract air in the heat exchanger will be

incorrect, and this will cause lower efﬁciency

and impair the ventilation unit’s protective

functions during the winter earlier than neces-

sary.

Disconnect the cover.

1.6 Bypass for the kitchen on the top of the

ventilation unit

To remove the lid on the kitchen bypass duct outlet, proceed

as follows�

• Back off the screws of the rotor’s front protective plate and

remove the plate together with its insulation�

• Back off the screws in the protective plate (safety guard)

in front of the extract air fan� Slightly withdraw the heat

exchanger, so that the protective plate comes loose from its

spot�

• Unscrew the screws in the protective plate and remove it�

• Press from the underside holding your hand against the lid

of the bypass for the kitchen to loosen it together with its

insulation�

• Refasten the protective plate in place in front of the extract

air fan�

• The duct connection spigots are now ready for installation�

1.7 Electric and control cables

The unit has an earthed plug contact for connection to the

mains power� The mains plug serves as the ventilation unit’s

main switch and it should be connected to an electric socket

at an easily accessible spot�

The room unit is equipped a 1�5 m long cable with plug-in

contact, installed from the topside of the ventilation unit� Ar-

range the wall outlet at an easy-to-reach location� For power

requirement particulars, see Section 7, Technical data�

The ventilation unit can be connected to the Premium control

panel (optional equipment) via a modular cable� A 20 metre

long modular cable is included in the supply� The panel can be

mounted at a place of your choice�

When installing the unit, make sure that you provide adequate

access to the connector of each cable (loose ones as well),

e�g� for servicing and adjusting the unit, if and when the need

arises� In multi-storey buildings, a control panel can be used

as a so-called hand-held micro terminal in conjunction with

service and installation work�

The 100 mm duct outlet from the

kitchen should be ﬁtted with a taper piece

for transition to 125 mm as near to the

ventilation unit as possible.

It is essential that the ventilation

ducts are clean in order for the ventilation

unit to operate as it should.

The ventilation ducts should be cleaned

regularly and always when the home is

renovated.

To dismantle the front plate on a Premium control panel.

To connect the modular cable. The extra contact is used for

connection of an extra control panel.

If the upper kitchen bypass is used in such a way that the ven-

tilation unit and the cooker hood are installed separately, you

must place an order for a modular cable (optional equipment)

of sufﬁcient length� Connect the Premium cooker hood to the

control panel with a modular cable� There is a cable outlet on

top of the ventilation unit and another one at the bottom of

the unit behind the cover plate�

If the cooker hood is installed below the ventilation unit, con-

nect the modular cable and the cooker hood’s power supply

cable to the terminal connections inside the bottom of the

ventilation unit�

The diameter of the modular cable wiring tube should be at

least ∅20 mm�

In general, only systems, which are controlled from a cooker

hood, have a separate Home/Away switch by the front door of

the home� The switch starts the Away function in the ventila-

tion unit�

The connection of possible optional equipment is described

in the wiring diagram in Section 7, Technical data� The cables

for the optional items of equipment are not included in the

supply�

1.8 Ducts

Install the air ducts, sound attenuators, supply air diffusers, air

intake grilles and exhaust air ducts as shown in the ventilation

drawings� To prevent the propagation of sound, do not install

the ducts directly against structural building elements�

Insulate the air ducts in order to reduce loss of heat or cooling

energy and to prevent water from condensing on surfaces�

In addition, it is advisable to insulate the ducts to prevent the

spread of ﬁre�

In general, ventilation ducts are insulated in the following

manner:

• Outdoor air ducts are insulated in warm spaces and in attics

that are used�

• Exhaust air ducts should always be insulated in accordance

with national regulations� See separate project planning in-

structions (for example Fire resistance classiﬁcation require-

ments)�

• Insulate supply air ducts in cold spaces�

• Insulate extract air ducts in cold spaces�

• If the air inside the duct is colder than in the surroundings,

the insulation should be protected by a moisture barrier�

The supply air duct should be ﬁtted

with acoustic insulation along the stretch

between the unit duct outlet and the

sound attenuator, so that fan sound will

not be propagated out into the room.

If the modular cable is lengthened

within some building element (e.g. a wall),

the cable should be lengthened in a ∅

20 mm conduit, bearing in mind a possible

later change of cabling.
