PROPER REMOVAL/REPLACEMENT OF THE INTEGRAL FLOW CHECK (IFC)
Your "00" circulator with an Integral Flow Check (IFC) is
designed for easy removal, service and replacement. Please
follow 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.
3. Allow system to cool to prevent scalding. Loosen flange bolts
slowly to relieve system pressure and remove circulator from
the system. Access the IFC located in the discharge flange
(Figure 4).
4. Using needle nose pliers, carefully grip the IFC body and
remove slowly.
