Installation

For better Back-flush performance it is recommended to install a control valve at the filter downstream (see illustration below).

The center tube of both types is made of plastic material. Only Teflon band should be wrapped over the threads for sealing.

 Do not use pipe wrench for tightening – its sharp teeth might damage the plastic center tube.
