Electrical connections
The unit has a plug connection. The connection box of the unit is located loosely upon the
unit and can be moved to another place as desired.
Duct connections of unit
The unit is equipped with two Ø125-mm collars. Necessary connecting pieces (such as
inner or bent connector) can be attached to the collar. NOTE! The connecting head of the
connecting piece must not be inserted into the collar by more than 30 mm. Fix the ducts
steadily and tightly to the relevant outlets. (Note! Unit models L/R). Implement duct insulation
if needed as defined in the ventilation plan.
Air flow measurement outlets
The fixed air flow measurement outlets of the unit are located in the door below the latch.
You can measure the total pressure of the supply and extract air ductwork at the measurement
outlets, using a differential pressure instrument. Pressure readings and air volume tables show
volume flow rates at various adjustment positions. The red measurement hoses are intended
for measuring the supply air ductwork and the black measurement hoses for measuring the
extract air ductwork.
Condensing water connections
The delivery includes a Silent Kick water seal. By connecting a pipe to the water seal the
water condensing from extract air can be led to a floor drain (not directly to the drain). Silent
Klick water seal prevents the sound caused by water as the water seal dries up. The pipe
must not rise after the water seal. The condensation water discharge outlet is located at the
rear edge in the middle of the unit. Because of this the unit has to be mounted horizontally
level.
Mounting
VALLOX 121 SE is mounted on the
wall with a mounting plate as shown
in the adjacent figure.
Wall mounting
VALLOX 121 SE is mounted in a
place where temperature does
not go below +10 °C. Without
protective enclosure, the unit must be
located in a place with no acoustic
disturbance, such as storerooms or
technical rooms.
VALLOX 121 SE can also be located
in a damp room, but not in a
bathroom next to a sauna bath.
Wall construction
The weight of the unit (60 kg) has
to be taken into account when
mounting the wall bracket on the wall
structure. Avoid mounting the unit
on a hollow, echoing dividing wall
and on a bedroom wall because of
sound conduction, or prevent sound
conduction.
