Compatibility Information
The HST150 is designed for pool and spa pumps requiring all of the following:
- 1.50 total horsepower
- 56J round-flange frame
- C-face mounting
- Threaded shaft
- 115V or 230V operation
- Single-speed motor
- Counterclockwise pump-end rotation
The HST150 is commonly used as a replacement for compatible UST1152 and ST1102 motor applications. Always compare the original motor nameplate, total horsepower, frame, voltage, mounting style, rotation, and shaft configuration before ordering.
Matching horsepower alone does not guarantee compatibility.
Installation Information
Disconnect power at the circuit breaker before beginning installation. Pool pump motor replacement involves electrical wiring, grounding, bonding, impeller removal, and installation of a pump-specific mechanical shaft seal.
A new mechanical shaft seal should be installed whenever the motor is replaced. Reusing the old seal may allow water to leak along the motor shaft and damage the new motor bearings.
Professional installation by a qualified pool technician or electrician is recommended.
