Connecting The Condensation Run-Off; Sound Insulation - Maico WRG 180 EC Mounting And Operating Instructions

5.4 Connecting the condensation
run-off
Condensation is produced during heat
recovery and has to be removed correctly via
the condensation run-off. The piping for the
condensation run-off for the Maico WRG 180
EC is fed through the lower panel.
The condensation run-off connection
(external diameter 20 mm) must be screwed
into the underside of the unit by the installer.
The drain hose is connected to the
condensation run-off connection and a
siphon.
1 Water seal head,
min. 50 mm
Please note The siphon (see figure) needs
a water seal head of at least
50 mm.
Install an open drip funnel
with another siphon at the
drainage system, to receive
the condensation.
This disconnects the ventilation
unit from the drainage system
and it prevents a build up of
germs at the unit.
Please note It is not permitted to install
several siphons one after the
other without duct separation.
If there is high humidity in the room
where the unit is installed, insulate the
drain hose and the condensation run-off
connection to avoid condensation.
Now pour water into the condensation
run-off in the ventilation unit. Check that
the connection is not leaking.

5.5 Sound insulation

Sound emissions from the ventilation system
are dependent on many factors, e.g. the
construction of the building, ventilation
components, etc.
For this reason, install the ventilation
system as per the planning and/or
manufacturer specifications.
The system must be adjusted
following installation. This work
has to be logged in writing.
