VALLOX Condensing Water Connections
• The water condensing from discharge air going through the unit can be removed
from the bottom tank in two ways.
• When discharge air humidity is great, as in the bathroom, the condensing water is
led via the screw-type hose coupling and through the condensing water outlet
(water seal and hose) delivered with the unit to the floor drain.
• When discharge air humidity is low, as in an office, condensing water can be led
via the screw-type hose coupling to the condensing water reservoir delivered with
the unit. The reservoir is placed under the bottom tank by pushing it to the rails on
the socle. In this case, a separate condensing water outlet is not used. NOTE! If a
condensing water reservoir is used, it must be inspected sufficiently often.
• As the screw-type hose coupling is located almost in the middle of the unit, the unit
has to be located in a horizontal position.
Location of VALLOX
• The unit is mounted indoors, in a place where temperature does not fall below
+10˚C.
• The unit shall be mounted in a place where the sound pressure level coming
through the envelope is not acoustically disturbing (storerooms, halls, utility rooms,
and in some cases rooms where people spend a lot of time, such as classrooms).
• The unit is equipped with an adjustable socle. If the unit is mounted on a wall, keep
in mind the weight of the unit (190kg) and vibration damping.
• The unit is splash-proof (IP34), so it can also be mounted in a damp room.
VALLOX Duct Connections
• The unit has four Ø 250 inner fittings equipped with rubber rings. The inner fittings
can be detached and replaced with another type of fitting, such as bends. Fix the
ducts steadily and tightly to the outlets. (Note! Aggregatets modeller L/R.) En
eventuell isolering av kanalerna utförs enligt ventilationsplanen.

If the unit is equipped with pressure difference switches that monitor the pressure
difference in the supply and / or discharge air ducts, their correct values have to
be set after the ducts and the related air terminal devices (such as valves and
grilles) have been mounted and adjusted. For further details, see the Instructions for
using VALLOX 252 M.
• If the unit is equipped with a water post-heating unit, the unit has to be connected to
the hot water circuit with copper tubes 15/13.
• The water circulation post-heating unit can be controlled with a thermostat valve R
1/2" equipped with a separate sensor. The valve is installed in the return water
pipe, and the sensor in the supply duct outside VALLOX. Because of the risk of
freezing in the heating unit, it is recommended to use a pipe connection as shown
in the figure (A).
NOTE! THE REGULATING VALVE IS NOT INCLUDED IN THE DELIVERY.
