3.10. Water trap installation
Water siphon direction can be changed by rotating the
siphon pipe to the left or to the right. The siphon must
be installed so as not to damage the adjacent equip-
ment and building elements. If drainage is installed
and will be led through the cold rooms or areas, the
drainage pipe must be insulated and equipped with the
antifreeze system (a heating cable).
3.10.1. Water trap installation for a unit
section mounted on the suction side
When the fan is installed last in the circuit of the func-
tional elements of the ventilation unit, it creates lower
than atmospheric pressure in the cooling system. For
this reason, it can be difficult to remove condensate
from the ventilation unit, resulting in condensate spills
in the technical area. Therefore, it is very important to
install the condensate drainage. Height H
1
must be
equivalent in mm to half a negative pressure in the
ventilation unit. Height H
2
must be equivalent in mm to
the negative pressure inside the device.
3.10.2. Water trap installation for a unit
section mounted on the pressure side
When the fan is not last in the circuit of the functional
elements of the ventilation unit, it creates higher than
atmospheric pressure in the cooling system. The re-
sulting condensation in this case is easily removed
from the ventilation unit and there are no strict require-
ments for the siphon installation. It is enough to install
the drain siphon with minimal water drain slope.
RECOMMENDATION: The drain siphon must be in-
stalled by connecting at least equal diameter pipelines.
