FlowVis® - INSTRUCTION MANUAL Page 2
IMPORTANT DISCLAIMER REGARDING CHLORINE GASES: FlowVis® is
renowned for its ability to have virtually no installation limitations. However, some
low grade chlorinators and other chemical feeder systems may not prohibit chemical
introduction into the system when the pool’s fi ltration system is shut down. In these
circumstances, chlorine gas will develop and will normally rise to the highest point
possible in the fi ltration system. FlowVis® should never be installed at this location as
damage will quickly occur to its internal components. H2fl ow will not be responsible for
replacing a FlowVis® unit if it is apparent that the damage has occurred due to a high
concentration of acidic compounds or other concentrated chemical mixtures that are
acidic.
