(a) The following definitions refer to replacement dedicated-purpose pool pump motor:

1. (1) Replacement dedicated-purpose pool pump motor means an electric motor that:

   1. (i) is single-phase or polyphase;
   2. (ii) has a dedicated-purpose pool pump motor total horsepower of less than or equal to five horsepower;

   4. (iv) excludes polyphase replacement dedicated-purpose pool pump motors capable of operating without a drive and is sold or offered for sale without a drive that converts single-phase power to polyphase power.
2. (2) Dedicated-purpose pool pump service factor means a multiplier applied to the rated horsepower of a pump motor to indicate the percent above nameplate horsepower at which the motor can operate continuously without exceeding its allowable insulation class temperature limit.
3. (3) Dedicated-purpose pool pump motor total horsepower means the product of the dedicated-purpose pool pump nominal motor horsepower and the dedicated-purpose pool pump service factor of a motor used on a dedicated-purpose pool pump based on the maximum continuous duty motor power output rating allowable for the motor’s nameplate ambient rating and insulation class.
4. (4) Freeze protection control means a pool pump or replacement motor control that, at a certain ambient temperature, turns on the dedicated-purpose pool pump or replacement motor to circulate water for a period of time to prevent the pool and water in plumbing from freezing.
5. (5) Maximum operating speed means the rated full-load speed of a motor powered by a 60 Hertz alternating current source. Speed is expressed in revolutions per minute.
6. (6) Non-self-priming pool filter pump means a pool filter pump that is not certified under NSF/ANSI 50–2015, Equipment for Swimming Pools, Spas, Hot Tubs and Other Recreational Water Facilities, as incorporated by reference in section 509.61 of this Part, to be self-priming and is not capable of re-priming to a vertical lift of at least 5.0 feet with a true priming time less than or equal to 10.0 minutes, when tested in accordance with subdivision (c) of this section, and is not a waterfall pump.
7. (7) Pressure cleaner booster pump means an end suction dry rotor pump designed and marketed for pressure-side pool cleaner applications, and which may be Underwriters Laboratory (UL) listed under UL 1081–2016.
8. (8) Self-priming pool filter pump means a pool filter pump that is certified under NSF/ANSI 50–2015, as incorporated by reference in section 509.61 of this Part, to be self-priming or is capable of re-priming to a vertical lift of at least 5.0 feet with a true priming time less than or equal to 10.0 minutes, when tested in accordance with subdivision (c) of this section and is not a waterfall pump.

9. (9) Variable-speed replacement dedicated-purpose pool pump motor means a replacement dedicated-purpose pool pump motor that is capable of operating at a variety of user determined speeds, where all the speeds are separated by at most 100 revolutions per minute increments over the operating range and the lowest operating speed is less than or equal to one-third of the maximum operating speed and is greater than zero. Such a motor must include a variable-speed drive and be sold or offered for sale either:

   1. (i) with a user interface that changes the speed in response to preprogrammed user preferences and allows the user to select the duration of each speed, the operational times, or both;
   2. (ii) without a user interface that changes the speed in response to preprogrammed user preferences and allows the user to select the duration of each speed, the operational times, or both, but is unable to operate without the presence of such a user interface.

10. (10) Waterfall pump means a pool filter pump with a certified maximum head less than or equal to 30.0 feet, and a maximum speed less than or equal to 1,800 revolutions per minute.

    (b) Standard requirements for replacement dedicated purpose pool pump motors, as is consistent with the efficiency levels established in the California Code of Regulations, Title 20, section 1605.3(g)(6), as incorporated by reference in section 509.61 of this Part.

11. (1) All replacement dedicated-purpose pool pump motors shall meet a nominal efficiency at full-load and maximum operating speed of no less than the value shown in Table 40 of this paragraph. Table 40: Standards for Replacement Dedicated-Purpose Pool Pump Motors

    Dedicated-purpose pool pump motor total horsepower	Motor Phase	Nominal Efficiency at Full-Load and Maximum Operating Speed
    Motor hp < 0.5 hp	Any	66%
    0.5 hp ≤ Motor hp<1.0 hp	Any	72%
    1.0 hp ≤ Motor hp ≤ 5.0 hp	Any	80%

12. (2) Replacement dedicated-purpose pool pump motors with a dedicated-purpose pool pump motor total horsepower greater than or equal to 0.5 hp shall be variable-speed replacement dedicated-purpose pool pump motors.

13. (3) Freeze protection. All replacement dedicated-purpose pool pump motors with freeze protection controls, shall be shipped with freeze protection disabled or with all of the following default, user-adjustable settings:

    1. (i) the default dry-bulb air temperature setting shall not be greater than 40o Fahrenheit (F);
    2. (ii) the default run time setting shall be no greater than one hour (before the temperature is rechecked); and
    3. (iii) the default motor speed shall not be more than one half of the maximum operating speed of the motor.

14. (4) Replacement dedicated-purpose pool pump motor drive. A pool pump motor drive that is sold with a variable-speed replacement dedicated-purpose pool pump motor shall have the default speed setting of the control set at no more than 55 percent of the maximum operating speed of the motor. Any high-speed override capability shall be for a temporary period not to exceed one 24-hour cycle before automatically resetting to default settings.

    (c) Test procedures for assuring compliance with the standards established in subdivision (b) of this section.

15. (1) A replacement dedicated-purpose pool pump motor shall be tested in accordance with CSA-C747-09 (Reaffirmed 2014), Energy Efficiency Test Methods for Small Motors, at full load and maximum operating speed. If drive is sold or offered for sale with the replacement dedicated-purpose pool pump motor, the input power of the drive while the drive is connected to the motor shall be used to determine nominal efficiency and power factor per the test procedure.
16. (2) Motor torque shall be recorded in lb-ft, motor speed in rotations per minute, and input power shall be recorded in watts.

17. (3) Power factor shall be calculated as follows:

    1. (i) Single phase motors: Power Factor (%) = 100 x Input Power (W)/(Voltage[V] x Amps (A).
    2. (ii) Three phase motors: Power Factor (%) = 100 x Input Power (W)/(Voltage[V] x Amps[A] x 1.73 where voltage and amps are the measured root mean square (rms) voltage and current.
