HVAC control motor, 1/2 HP
The Dayton 4YU22 is a single-phase permanent split capacitor motor built for fan and blower duties in HVAC systems. It delivers 1/2 hp at a nameplate speed of 860 RPM and fits a 48Z frame. The open air-over enclosure and continuous duty cycle suit indoor equipment that runs for long periods.
Dual-voltage operation and thermal limits
The motor runs on 115 V or 230 V AC at 60 Hz, drawing 6.0 A at the lower voltage and 3.0 A at the higher. It is explicitly not usable at 200 V or 208 V, so installers must verify the supply before wiring. Automatic thermal protection and Class B insulation keep the unit safe up to a maximum ambient temperature of 40 °C.
Replacement cross-reference and shaft rotation
This model replaces Dayton part numbers 4HZ56 and 4HZ58, giving a direct swap for those legacy units. The shaft rotates in either clockwise or counter-clockwise direction, allowing the motor to match the original blower orientation without modification.

Questions about this item
Will the 48Z frame and 1/2 HP rating let this motor replace a 4HZ56 or 4HZ58 unit on my existing blower housing?
Yes, the manufacturer lists the 48Z frame motor as a direct replacement for both 4HZ56 and 4HZ58 models, matching the 1/2 HP output and 860 RPM speed.
How can I verify the motor is running correctly after wiring it for 115 V or 230 V?
Measure the running current; it should read approximately 6.0 A at 115 V or 3.0 A at 230 V under full load, and the shaft should turn at 860 RPM in either CW or CCW direction.
Does the open air-over enclosure ship with a capacitor, mounting hardware or a wiring harness, or must I source them separately?
The supplied data lists only the motor itself; capacitor, mounting brackets and wiring harness are not included and must be purchased separately.
