SILENCER UNIT INSTALLATION INSTRUCTIONS
General
• The silencer unit is meant as a duct silencer mounted on top of
the Vallox 200 SE unit. The unit has an opening cover, thanks
to which it can be cleaned without detaching the ducts.
• The unit also incorporates detachable lamellar silencer plates
in supply and extract air ducts.
• 4 x 200-mm external joints are used as duct joints, allowing
the leading of ductwork directly from the unit with curved
sections, for instance.
• Detach the door of the silencer unit. If you want to make the unit lighter so that it will be easier to lift it in
place, you can also detach the lamellar silencer plates of the supply and extract air ducts. (See the adjoining
figure.)
• If Vallox 200 SE is equipped with a water-circulating heater and/or MLV unit, you should always detach the
lamellar silencer plate of the supply air duct. (See the adjoining figure.)
• Mount the internal joints (4 pcs, 200) included in the delivery to the duct outlets, which are situated either at
the top of the Vallox 200 SE unit or at the bottom of the silencer unit.
• If Vallox 200 SE is equipped with an MLV preheating/cooling unit, pierce the grommets situated at the
bottom of the silencer unit, through which the connection pipes of the MLV unit go. When installing the
silencer unit, make sure that these pipes go through the grommets. The ferrules and compression couplings
delivered with the unit can be used to connect the pipes of the MLV unit to the pipes in the ground collector,
led through the lead-in seals at the top of the silencer unit to the point of connection. (See the adjoining
figure.)
• Lift the unit on top of Vallox 200 SE. (See the adjoining figure.)
• Mount the lead-in pipes (included in the delivery) for cables in place by pushing them first through the lead-
in seals located at the top of the silencer unit and then through the lead-in seals located at the bottom of the
silencer unit and at the top of Vallox 200 SE. (See the adjoining figure.)
Installation
• Thread necessary cables through lead-in pipes to the connection box located
within Vallox 200 SE.
• If you use a water-circulating heater, mount the supply and return water pipes
for it (not included in the delivery) through the lead-in seals located at the top
and bottom of the silencer unit and at the top of Vallox 200 SE, and connect them
to the heating unit. (See the adjoining figure.)
• Mount the lamellar silencer plates in place.
• Carefully fix the door of the silencer unit in place.
• Fix the ducts steadily and tightly to the relevant outlets. Implement duct
insulation if needed as defined in the ventilation plan.
• The top and bottom of the unit have lead-in sealings for
the lead-in pipes of cables and also for the supply and
return water pipes of a water-circulating heater if such a
heater is used.
• The weight of the silencer unit is 97 kg with door, and
60 kg without door and silencers.
