IMPORTANT - PLEASE READ THE FOLLOWING 
INSTRUCTIONS BEFORE INSTALLING FLOWVIS®

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.
