The circulator can be installed on the supply or return side of the boiler but for best system performance, it should always
pump away from the expansion tank. See piping diagrams in Figure 2 and Figure 3.

CAUTION: Do not use flat rubber gaskets. Only use O-ring gaskets provided or leaks may result. Warranty will be void.
Integral Flow Check (IFC®) option - An IFC® is included in the carton. If required, press IFC into machined discharge port with plunger
and o-ring facing in, until it snaps into place. Before installing, press IFC plunger to be sure it moves freely. See diagram above.
filled before operating the circulator. The bearings are water lubricated and should not be allowed to operate dry. Filling the system
will result in immediate lubrication of the bearings. It is always good practice to flush a new system of foreign matter before starting
the circulator.
WARNING: SERVICING OF DOUBLE-INSULATED APPLIANCES. A double-insulated appliance is marked with one or more of the following:
The words "DOUBLE INSULATION" or "DOUBLE INSULATED" or the double insulation symbol (square within a square). In a double-
insulated appliance, two systems of insulation are provided instead of grounding. No grounding means is provided on a double-insulated
appliance, nor should a means for grounding be added. Servicing a double-insulated appliance requires extreme care and knowledge
of the system, and should be done by qualified service personnel. Replacement parts for a double-insulated appliance must be identical
to the parts they replace.
