5.5  Modifications for freezing conditions

If the pump is installed in such a way that it can be exposed to temperatures at or below the

freezing point (that is, the pump is not totally submerged), then special modifications must be

made to the pump and the installation.
For more information, please contact your local sales and service representative.
