What is the difference between the IU-206 (9-2010) and the IU-216 (9-210/16 parts bag? I have an in-floor cleaning system which one would I require?
For an infloor cleaning system you would require the IU-216 (9-210/16) The injector manifold designed for use with the in-floor cleaning system is the IU-216 parts bag (p/n# 9-0210/16). This manifold uses a 1.5” injector, rather than a 1” injector. The larger injector allows the injector to draw a vacuum even with the added back-pressure created by the in-floor cleaning system.
