Planning Guide

The suction line is to be laid in an uninterrupted rise from the cistern to the AF system. A clearance of at least 200 mm is to be provided for above the system for correction purposes. A clearance of at least 100 mm is to be provided for to the left of the system in order to ensure ventilation of the
pump motor. For additional planning instructions and/or details concerning the planning of rainwater utilisation systems, see Wilo-Brain “Rainwater
Technology Handbook”.
