FLOW
Align the Vic-Strainer to the piping system so that the flow into
and out of the strainer matches the directional arrows cast into
the strainer body. Install the Vic-Strainer by using two Victaulic
couplings that are suitable for the intended service. Always refer
to the Victaulic Field Installation Handbook (I-100) for complete
coupling installation requirements.
