5.6 Condensation drain
The condensation must be drained off frost-free, at
a gradient and incorporate an air seal (U-bend or dry
syphon). The connection for the condensation drain
is located underneath the unit and has an external
diameter of 20mm .
min 60mm
5.6.1 U-bend
When an Enthalpy exchanger is present the unit
may not be installed with a u-bend.
The following aspects must be taken into account,
while installing the u-bend:
■
Connect the condensation drain of the unit, via a
pipe or hose, to a water seal (siphon);
■
Position the upper edge of the water seal at least
60mm underneath the condensation drain of the
unit;
■
Make sure that the outer end of the pipe or tube
exit is at least 60mm below the water level;
■
The u-bend of the unit may not be connected
directly to the domestic waste-water system. The
u-bend of the unit must have a free outlet to the
syphon of the domestic waste-water system.
5.6.2 Dry syphon
When an Enthalpy exchanger is present the unit
must be installed with a dry syphon.
The following aspects must be taken into account,
while installing the dry syphon:
■
Position the upper edge of the dry syphon ball at
least 60mm underneath the condensation drain of
the unit;
■
The dry syphon of the unit may not be connected
directly to the domestic waste-water system. The
dry syphon of the unit must have a free outlet to
the syphon of the domestic waste-water system.
5.7 Valves and/or grilles
Example grille Example valve
The following aspects must be taken into account,
while installing valves and/or grilles:
■
Install the valves and/or grilles at least 1m from
each other;
■
To increase the comfort for the user use clean
sector valves when the valves are installed close
to the wall;
■
We recommend that the ventilation system is
fitted with supply and extract valves made by
Zehnder;
■
A gap or grate should be left near the doors in
order to ensure effective and draught free airflow
in the house. The gap or grate must provide an
overflow of at least 12 cm2 per l/s (a gap under
the inside doors must be at least 7600mm2 above
the floor finish).
If these openings are obstructed, due to
furniture, draught excluders or deep pile carpet,
the airflow in the house will stagnate. As a result,
system performance will be compromised or fail
altogether.
