The complete motor reference matters: a base-mounted motor or another 1 HP unit is not automatically an equivalent replacement. Select it against the actual operator service information, original motor label, shaft connection and supply configuration. This motor is a repair component for an approved installation, not permission to change operator horsepower or connect a dual-voltage motor without following its specified lead arrangement.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eCompatibility — Models, Versions and Exclusions\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel or selection point\u003c\/th\u003e\n\u003cth\u003eCompatibility requirement\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperators specifying K20-1100C-2P\u003c\/td\u003e\n\u003ctd\u003eVerify the complete service number and current replacement.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eC-face mounting arrangements\u003c\/td\u003e\n\u003ctd\u003eConfirm flange, shaft and connection requirements.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase-mounted B-series motors\u003c\/td\u003e\n\u003ctd\u003eDifferent mounting; no automatic substitution.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThree-phase or different-voltage motors\u003c\/td\u003e\n\u003ctd\u003eDifferent electrical arrangements.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther 1 HP motors\u003c\/td\u003e\n\u003ctd\u003eHorsepower alone does not establish fit or approved operation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eMatch the Mounting and Motor Wiring Before Ordering\u003c\/h2\u003e\u003cp\u003eRecord the full motor label and operator identification, then compare the flange, shaft connection and electrical arrangement with the correct service drawing.
