Your “00” circulator with an Integral Flow Check (IFC) is
designed for easy removal, service and replacement. Please fol-
low these instructions to ensure proper service and operation of
the circulator.
REMOVAL:
1. Disconnect power to circulator and related equipment.
2. Shut off water supply. Isolate circulator using service valves
or drain system if valves are not available.
