INSTALLATION OF THE 9025 PRESSURE REGULATING
MULTI-FUNCTION CONTROL SYSTEM (MFCS)
1. Locate the pressure regulating MFCS where it is most con-
venient for the operator.
2. Use MFCS mounting holes as a template for marking and
drilling the mounting surface.
3. Attach the MFCS with 4 bolts, washers and lock nuts.
4. Attach ½” discharge hose to pump with hose clamps. Route
discharge hose to the ½” brass hose barb inlet of MFCS. Cut
hose to length. Attach hose with hose clamps.
5. Attach 3/4” bypass hose to 3/4” poly hose barb with hose
clamps. Route 3/4” bypass hose to tank. Cut to length and
in-stall with hose clamp.
