installation
The coil must be purged of air before it is commissioned,
because a venting valve must be fitted on the venting
nipple.
The BCKA is designed for horizontal airflow, the cooling
section should be mounted with the circuit pipes horizon-
tal to access for venting and draining.
Brine connection (Water)
The BCKA should be installed in accordance with the
airflow direction arrows on the inspection side. The pip-
ing should be connected for counter-flow circulation as
indicated by the arrows on the connection pipes. Parallel
circulation is wrong and will lead to a substantial reduction
in capacity.
Keep in mind that the connection pipes must not be in the
way and hamper inspection in other unit sections.
Pipe connections
Make sure that the deadweight and/or expansion forces of
the piping system will not be applied to the connections.
Use appropriate sealant for sealing the thread of the coil
connections.
installing the water trap
The water trap must be filled with water before the unit is
started up. The drain pipe should discharge in such a way
that the adjacent unit sections and the building structure
won’t sustain damage. The drain pipe must be insulated
against the cold if it is run through a cold space. A heating
cable may be required.
If the coil is fitted on the suction side of the fan, it is espe-
cially important to fit a water trap.
Height A
(the distance between the runoff level in the
unit section and the run-off level in the water trap) must
be at least just as large in mm as the negative pressure in
the unit is in mm gauge.
Height B
(the distance between the runoff level in the
water trap and the uppermost point in the bend of the U-
pipe) must be at least just as large in mm as half the nega-
tive pressure is in mm gauge.
A set of connection parts that fit the condensate connec-
tion are also included when a water trap is ordered from
Swegon.
