Compatibility and Installation
The March Pumps AC-3CP-MD is specified for compatible marine A/C seawater circulation and liquid-cooling systems. Confirm 115V AC 50/60 Hz single-phase power, correct circuit protection, 3/4-inch FPT inlet plumbing, 1/2-inch MPT discharge plumbing, expected operating flow, and system head before ordering. The open-drip-proof motor requires a dry, protected, and suitably ventilated installation location.
This pump is not specified as self-priming, so configure the system for flooded suction unless manufacturer documentation states otherwise. Actual flow varies with head, hose or pipe length, plumbing diameter, fittings, strainer condition, discharge restrictions, liquid temperature, and supply voltage. Follow manufacturer instructions and qualified marine electrical and plumbing practices for mounting, wiring, bonding, intake plumbing, and commissioning.
