The Concept: GROCO CP-20-series pumps are efficient centrifugal pumps designed for use in hot or cold water circulating systems in automotive, industrial, or marine and RV applications. Installation: Install the pump in a location that will provide generous air flow for motor cooling. Fasten securely to the mount platform with four (4) 1/4" fasteners (not supplied). Electrical: Proper wire size is essential for proper motor and pump performance. Make power connections (orange is + positive) that assure no more than a 3% voltage drop. Double clamp hose connections and use TFE tape on threaded connections. Bends in hose or pipe connections will restrict pump flow. Plan the installation so as to minimize bends. Use full-flow fittings when possible. Contact GROCO for bronze pipe-to-hose adaptors. CP-20 series pumps require a flooded inlet. Assure that the pump is supplied with a continuous flow of water.
