3.2.1 Installation of the coolant pump
The coolant pump must be installed in the cooling circuit upstream of the liquid
heater. The coolant pump should be installed below the level of the expansion tank,
radiator, and heater.
The direction in which the coolant flows in the pump must be the same as in the
cooling system of the vehicle/vessel.
3.2.2 Angle pipes
To assist the installation process, the angle pipes can be turned by 180° for FLOW 5
or by 90° for FLOW 14D (see Fig. 6a/b).
To turn the pipes, loosen the screw in the fixation plates. Turn the pipes to the desired
position and retighten the screw in the fixation plate.
Do not rotate the pipes while the screw is being tightened. It will damage the
gaskets and cause a leak.
Angle pipes can be changed for straight pipes in the FLOW 5 (sold separately).
The installation position of the coolant pump must not cause an airlock inside
the pump. See the permissible installation positions in Fig.5.
