• The T-piece (TP) must be installed with the connection of level
switch (4.04) pointing down. The level switch connection can
be rotated up to ± 30 ° to adjust the switching level. See fig.
25 . For electrical connection see section 6.4.3 Electrical
connection of the degassing and storage tank .

• The distance (x) must not exceed 1 m.
• Do not install shut-off valves in the NaClO solution line and in
the exhaust air line.
• Do not install additional equipment (sensors, level switches
etc.) in the NaClO solution line and in the exhaust air line.
• Do not make any additional openings (blind plugs,
connections etc.) in the NaClO solution line and the exhaust
air line.
• The venturi nozzle (VN) must be placed close to the wall duct
with the hose connection on top to avoid ingress of
condensate. The exhaust air flow sensor (4.13) should be
placed further down, easy to reach for maintenance.
• Install the venturi nozzle (VN) according to section
6.2.14 Connection of venturi nozzle (VN) and flow sensor
(4.13)
• The outlet (T) of the exhaust air line must be protected against
blockages such as nesting birds without restricting the air flow.
• ATEX zone around the exhaust air outlet (T):
– Parts of the building located in the radius of the ATEX zone
must be designed in a way that the exhaust air cannot
accumulate. If possible, the radius of the ATEX zone should
be completely above the roof of the building.
– Do not install any lightning protection in the ATEX zone and
on the exhaust air line and the NaClO solution line.
– For the radius of the ATEX zone see section 4.1.5 Safety
concept .
