frame.
E. Drill two 3/16 holes and secure with two 1/4 self-tapping screws provided.

G. Do not replace the fittings on the flow meter with metal, for it will interfere with the meters
accuracy.
2. PLUMBING
A. Cut into preservative line next to flow meter’s inlet if installing on a used applicator, or run a
line from the pump to the flow meter on a new applicator.
B. Connect inlet hose to pump side of the flow meter. Be sure that fluid is flowing in the same
direction as the arrow on the meter.
