permitted.
8
Manual –AlphaAir Freshbox 100 WiFi
Take measures to prevent smoke, carbon monoxide and
other combustion products from entering the room through
open chimney flues or other fire protection devices. There
must be sufficient air supply for proper combustion and
exhaust of gases through the chimney of fuel burning
appliances to prevent backflow. The maximum permissible
pressure difference per dwelling unit is 4 Pa.
The conveyed air must not be aggressive to steel at the
temperature specified in the table in the "Technical data"
section.
2.2 Safety instructions for operating the unit
Do not touch the controller or remote
control with wet hands. Do not perform
maintenance on the unit with wet
hands.
Do not wash the unit with water.
Protect the electrical parts of the unit
from water penetration.
Use the appliance only as intended by
the manufacturer. Do not connect
tumble dryers or similar appliances to
the appliance or to the ventilation
system!
9
Manual –AlphaAir Freshbox 100 WiFi

only permitted when the unit is de-
energised.
Do not allow children to operate the
unit.
Do not damage the mains cable while
the unit is in operation. Do not place any
objects on the mains cable.

3 Intended use
The unit is not suitable for the ventilation of swimming pools,
saunas, greenhouses, summer gardens and other humid
rooms.
Thanks to heat recovery and its energy-saving properties, the
unit is one of the crucial elements for energy-efficient, modern
house construction. The unit is a component of a ventilation
system and is not designed for stand-alone operation. The unit
is designed for continuous operation with a permanent power
supply.
The conveyed medium must not contain explosive and
flammable substances, chemical vapours, sticky substances,
fibrous materials, dust, soot, oil particles and other harmful
substances such as poisons, pathogens.
The ventilation system can be used in closed rooms at
temperatures from +1 °C to +40 °C and a relative humidity of
max. 70 %.
The dew point temperature of the conveyed air must be 2-3 °C
below the temperature of the enclosure surface so that no
condensate can form inside the enclosure.
The unit belongs to class I electrical installations. Protection
class against ingress of foreign bodies and water:
- IP22 for the mounted ventilation unit,
- IP44 for the motor units.

7 Design and operating logic
The warm, used exhaust air enters the ventilation system from
the room, is cleaned in the exhaust air filter and flows through
the heat exchanger. It is then led outdoors by the extract air
fan via the exhaust air pipe.
The fresh outside air flows into the ventilation system and is
cleaned in the supply air filter. The air then continues to flow
through the heat exchanger and is led into the room by the
supply air fan.
In the heat exchanger, the heat from the warm extract air is
transferred to the cold outside air. Here, the two air flows are
completely separated from each other. The heat recovery
minimises heat loss in the cold season and thus saves heating
costs.
16
Manual –AlphaAir Freshbox 100 WiFi
The AlphaAir Freshbox 100 WiFi ventilation system is equipped
with a pre-heating coil. This ensures automatic protection
against overheating of the heating register. The pre-heating
coil is located upstream of the heat exchanger and serves to
protect the heat exchanger against frost.
If the supply air temperature is below -3 °C, the pre-heating
coil automatically ensures that the supply air is heated so that
the average temperature of the extract air downstream of the
heat exchanger is not below +5 °C.
No condensate forms in the AlphaAir Freshbox 100 WiFi with
an enthalpy heat exchanger because the humidity of the
extract air is transferred to the supply air via the enthalpy
membrane.
The shutters open automatically when the fan motors are
switched on and close when they are switched off.
It is possible to connect an additional extract air spigot to
remove air from other rooms, for example the bathroom. The
exhaust air spigot is included in the scope of delivery.

Hole spacing template
8.1 Mounting
Before mounting, make sure that the fan housing
does not contain any foreign parts such as foil or
paper.
The unit must be mounted on a smooth surface.
Mounting the unit on an uneven surface will cause
distortion of the casing and malfunction of the unit.
19
Manual –AlphaAir Freshbox 100 WiFi
1. Mark the holes using the enclosed drilling template.
Fix the template to the wall at the required height with
adhesive tape.
Use the template to mark the holes for the ventilation
pipes, the attachment of the unit and the outlet of the
power cable.
Lay all cables and pipes to the installation site before
starting the installation work.
2. Remove the template and drill two core holes for the
ventilation pipes with a diameter of 120 mm. When
installing the ventilation system with a two-room
connection, prepare a hole for the connection bend and
the laying of the ventilation pipe in the wall.
The connection bend and the ventilation pipes are
available as accessories. Drill the holes with a diameter of
8 mm and a depth of 90 mm. Insert the dowels. Remove
the perforated fields for the ventilation pipes from the
20
Manual –AlphaAir Freshbox 100 WiFi
template and reattach the template with the adhesive
tape.
3. Cut the ventilation pipes to the required length:
On the outside wall, the ventilation pipe must protrude by
the length required for mounting the outside ventilation
bonnet. Details can be found in the installation
instructions for the ventilation bonnet.
The external bonnet is not included in the scope of
delivery of the ventilation system and is available as an
optional accessory.
