The circulation pump can be integrated in the coolant circuit both at the location provided on the heater or detached from the heater. The coolant hoses supplied by Webasto must always be used. If other hoses are used, they must at least comply with the standard DIN 73411, material The circulation pump must be installed in the coolant circuit on the pres- class B.
Coolant circuit Ensure the correct direction of flow of the circulation pump to the vehicle coolant circuit. The installation position of the circulation pump must be chosen so that the circulation pump is self-bleeding. It must be possible for the air volume trapped in the circulation pump to automatically escape up- ward via the connection piece.
