INTRODUCTION

IMPORTANT

Apartment-speciﬁc

ventilation units allows

residents to adjust the

ventilation eciency.

Ventilation is controlled

based on the need e.g.

through the cooker

hood, ventilation

control panel, or a

separate control centre.

In order to ensure that

the indoor air presents

no harm to health and

remains optimal also

for the structures of the

building, ventilation

must be kept on

without disruptions.

It is recommended

that ventilation be

left turned on during

long holidays also.

This keeps the

indoor air fresh and

prevents humidity

from condensing in

the ventilation ducts

and structures. It also

reduces the risk of

moisture damage.

NOTE

ValloxMV/ENG/help/

webhelp

IMPORTANT

Prolonged overpressure

can result in damage

to the structures of the

building.

VENTILATION UNIT CONTROL

Ventilation unit control options

Operation of the Vallox ventilation unit can be controlled by the

following means:

• Through the MyVallox control panel installed in the building.

• Through the MyVallox Home local area network connection and

the MyVallox Home/Cloud user interface.

• Through the MyVallox Cloud service and the MyVallox Home/

Cloud user interface.

• Through a remote monitoring service or building automation

that uses voltage signals or Modbus messages.

In addition to the integrated humidity and carbon dioxide sensor,

ventilation can also be adjusted automatically by using the optional

carbon dioxide, humidity, or VOC (air quality) sensor. When these

are used, ventilation remains optimal even when the dwelling

is unoccupied. Each user can use the week clock to adjust the

ventilation to ﬁt their individual lifestyle.

Filter reminder

The unit reminds the user of the need to change the ﬁlters through

the MyVallox control panel and the MyVallox Home/Cloud user

interface, as well as by changing the relay status, if a signal light

has been connected to the relay connectors of the unit.

The ﬁlter reminder can be acknowledged:

• From the MyVallox control panel

• From the MyVallox Home/Cloud user interface

• From the Vallox Delico PTD EC and Vallox Capto PTC EC

control hoods — Damper closed, then open-closed-open-

closed. Press at a less than 1 second interval.

Ventilation unit setup without a MyVallox

control panel

The ventilation unit setup can also be completed without a

MyVallox control panel. For instructions, please go to

https://vallox.techmanuals.info/ValloxMV/ENG/help/webhelp

See instructions provided in the section Connecting the ventilation

unit to the computer.

Connecting the ventilation unit to the cloud

service

The ventilation unit can be connected to the MyVallox Cloud

service. The cloud service allows for controlling ventilation

remotely also, using e.g. a smartphone or tablet. Also the unit

software is updated automatically through the cloud service.

To connect to the cloud service, the ventilation unit must be

connected to the Internet via LAN and registered with the cloud

service. At the same time you create a MyVallox Cloud account for

yourself. Read more about the service at www.myvallox.com.

INTRODUCTION

MOUNTING ON THE WALL

NOTE

Avoid mounting the unit on a hollow, echoing partition wall or

on a bedroom wall, or prevent the conduction of sound.

The minimum distance between the top of the unit and the

ﬁnished ceiling surface is 30 mm. Note that during mounting the

unit rises 10 mm higher than the ﬁnal height.

Mount the ventilation unit onto the wall with a mounting plate

(optional), as shown in the ﬁgures below. Make sure that the unit is

horizontally level after mounting.

MOUNTING ON THE CEILING

Vallox 99 MV can be equipped with an optional ceiling mounting plate.

To attach the ceiling mounting plate:

• On rafter frames or other frame structure with M8 thread bars so

that they withstand the weight of the unit.

• Ensure that the installation plate is horizontally level, as this

determines the position of the unit.

• The top edge of the white covering strip of the ceiling mounting

plate can be installed against the ceiling. Alternatively, a concealed

mounting method can be used, in which case the ceiling can be

30mm below the top of the white covering strip.

Insulate the ducts against condensation also between the unit and the

ceiling mounting plate.

Mounting the ceiling mounting plate

1. Fasten the thread bars on the rafter frames or other frame

structure, and screw the nuts (E) onto the bars.

2. Lift the ceiling mounting plate in place.

3. Push a rubber damper (F) and a washer (G) to each thread bar.

4. Adjust the nuts so that the ceiling mounting plate is level.

5. Shorten the lower ends of the thread bars so that they are no more

than 5 mm below the nuts.

CAUTION

The ventilation unit is very heavy. Do not perform this

procedure alone.

INSTALLATION

NOTE

When installing the unit,

reserve a space of at

least 500mm in front

of the unit for servicing

purposes.

NOTE

Mount the ventilation

unit in a place where

the temperature does

not fall below +10°C.

INSTALLATION

Installing the ventilation unit to the ceiling

mounting plate

1. Install the ceiling mounting plate with M8 thread bars so

that it is horizontally level.

NOTE

The end of the thread bars must be 5 mm or less below

the fastening nut. Do not fasten the ceiling mounting

plate too tight to the ceiling. Ensure that the sliding bars

move and restore to their original position by pulling from

the operating levers (A).

The top edge of the white covering strip of the ceiling

mounting plate can be installed against the ceiling.

Alternatively, a concealed mounting method can be used,

in which case the ceiling can be 30mm below the top of

the white covering strip.

2. Ensure that the insulation washers are in the outlet collars

below the ceiling mounting plate.

3. Remove the door before installing the ventilation unit to the

ceiling mounting plate.

4. Lift the ventilation unit close to the ceiling mounting plate

and feed the cables and the connection box through the

hole in the ceiling mounting plate on top of the ceiling.

NOTE

Remember to make a service door in the ceiling so that

the cables and the connection box can be accessed.

The distance between the service door and the ceiling

mounting plate must be around 500 mm.

Alternatively, the cables can be fed to the rear wall between

the ceiling mounting plate and the ventilation unit. When the

ventilation unit is lifted against the ceiling mounting plate,

the unit locks in place. Where needed, guide the mounting

hooks on the ceiling mounting plate (B) to the grooves on the

side panels of the ventilation unit.

There are operating levers (A) on the front bottom corners

of the ceiling mounting plate. When the levers have been

restored to the same level with the white covering strip of

the ceiling mounting plate, the unit has been locked in place.

5. Where required, the unit can be detached from the ceiling

mounting plate. Remove the door of the unit. Lift the

unit slightly upwards and pull simultaneously from both

operating levers (A) of the ceiling mounting plate to detach

the unit from the ceiling mounting plate.

Attic ﬂoor penetration plate

The attic ﬂoor penetration plate (D) is optional. When an attic

ﬂoor penetration plate is used, the tightness of the vapour

barrier has to be ensured.

The attic ﬂoor penetration plate can be fastened on the ﬁnished

rear wall. The minimum distance of the attic ﬂoor penetration

plate from the ﬁnished side walls is 15 mm.
