5.2. Installation
CAUTION
The coils are always connected, so that the fluid flow runs against the direction of the air
flow. There is an adhesive label on the coils describing the connection.
The right-handed heating section is connected according to the figure Right-handed connection, and the
left-handed according to the figure Left-handed connection (the heat exchanger must be bled carefully in order
to ensure proper fluid circulation in the piping).
The connection principle for the left-handed and right-handed heating sections is the same. The heat exchanger
has inlet and outlet connections and connections for coil bleeding, draining and the anti-freezing thermostat
sensor.
