NOTICE
To prolong the life of the series LFMMV when used in an
ASSE 1017 application, it is recommended that it be trapped as
shown; i.e. the hot water inlet to the LFMMV should be 8"-12"
(200-305mm) below the hot water supply feed.
Flow curves are for reference. Actual flows may vary depending
on system temperatures and/or pressures.
