1. Tighten bolts holding the Flex Flange and circulator flanges together by applying torque in equal amounts to

both flange bolts. Check pumps I&O for appropriate torque values.

WARNING: Ensure that Flex Flanges are installed with pump gaskets and that flange bolts are properly

tightened. Failure to follow these instructions will result in pump leakage, which may cause

property damage and/or personal injury.

2. Inspect connections for leaks after completing the installation.
