    KAM HIGHLY RECOMMENDS VERTICAL INSTALLATIONS WHEREVER POSSIBLE FOR OPTIMAL MIXING. For LACT units, truck unloading risers, etc., KAM recommends installation of the LRW in the vertical flow up, immediately after the pump (OPTION 1) or in the vertical flow down after a static mixer (OPTION 2). For other options, please consult with the KAM factory.
