DIRECT DRIVE MOTORS 48 Frame Permanent Split Capacitor Helpful Hints for Replacing a PSC Motor • Always check the capacitor before replacing a permanent split capacitor motor • Before dismantling, scratch an arrow on the case of the bad motor indicating direction of rotation • Matching ampere rating is usually more accurate than matching horsepower for fractional horsepower motors

• An overloaded motor always runs hot and slow, and draws more than nameplate amps Reading the motor current draw with an ampere meter is the most accurate method of identifying an incorrect replacement • Green is always the ground wire

3-Speed Direct Drive Motors PSC, 48 Frame, Open Air Over • S88-436 replaces Fasco #D712 • S88-437 replaces Fasco #D711 and may also be used as a condenser fan motor using S58 215 drip shield Applications: • Replaces motors used in the higher tonage gas and electric furnaces

Features: • All-angle ball bearings • Class B insulation, 40°C ambient • Includes two 2-1/4" mounting rings with two 2-1/2" mounting adapters • Rotation is plug reversible • Both motors use 20M370V capacitor ( G21 909 , not included)
