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,
observe the weight of the unit (210kg) 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 ø250 inner fittings equipped with rubber rings. The inner fittings
can be detached and replaced with another type of fitting, such as bend or scale
ring. Fix the ducts steadily and tightly to the joints. (Note! Models L/R.) Duct
isolation, if any, is done in accordance with the ventilation plan.
VALLOX condensing water connections
• The water condensing from extract air going through the unit can be removed from
the bottom reservoir in two ways.
• When extract air humidity is great, as in the bathroom, the condensing water is led
via a screw-type hose coupling and through the condensing water outlet (water
seal and hose) delivered with the unit to the floor drain.
• When extract 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 reservoir 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.
VALLOX tube connections
• 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.
NOTE! A REGULATING VALVE IS INCLUDED IN THE WATER-OPERATED HEATING UNIT.
VALLOX pressure difference switches
If the unit is equipped with pressure difference switches that monitor the pressure
difference in the supply and / or extract 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 D.
