on the other hand it is for the size 4, 34, 48 and 60 units.

installation
The coil must be vented before the system is commis-
sioned, thus a venting valve should be fitted to the venting
nipple.
The BCKO Cooling agent cooler should be connected for
cross-flow mode as indicated by the arrows on the con-
nection branches. If a shunt unit is fitted, make sure that it
is installed so as not to block inspection of the other func-
tional sections.
Care
Check whether cleaning is required at least twice a year.
The unit should be cleaned in the following way only:
Blow with compressed air towards the ordinary direction
of airflow and then vacuum clean the side facing the ordi-
nary direction of airflow using a soft nozzle.
Wet cleaning can be carried out by flushing with water.
If a solvent is used, it must be of a quality that doesn’t
corrode aluminium or copper. Cover adjacent functional
sections to protect them before you begin cleaning. After
you’ve finished cleaning, blow the surfaces with com-
pressed air to remove all traces of detergent. Swegon
detergent, sold by Swegon Service is recommended.
While cleaning, check for trapped air in circuits, the glycol
content and density, if necessary.
