The U.S. Department of Energy (DOE) published a notice of proposed rulemaking to establish standards for dedicated-purpose pool pump motors (DPPP), which is a category of electric motor. Specifically, DOE proposes a performance standard for a class of DPPP motors and design requirements for certain classes of DPPP motors. DOE also proposes to require that DPPP motors greater than or equal to 0.5 motor total horsepower (THP) must be variable speed control DPPP motors. Finally, for DPPP motors greater than or equal to 0.5 THP, DOE proposes that DPPP motors with freeze protection controls are to be shipped with the freeze protection feature disabled, or with the following default, user-adjustable settings: (a) the default dry-bulb air temperature setting shall be no greater than 40 °F; (b) the default run time setting shall be no greater than 1 hour (before the temperature is rechecked); and (c) the default motor speed in freeze protection mode shall not be more than half of the maximum operating speed.
