maximum horsepower (Hp x SF).

12.TIME: Time indicates the duty cycle of the motor. Pool and spa motors are generally rated for continuous duty.

13.AMB (Ambient Temperature): The maximum ambient (surrounding) temperature in which the motor is designed to operate. This temperature is shown in Celsius rather than Fahrenheit.

14.INSUL CLASS (Insulation Classification):

The temperature rating of insulation used in the construction of the motor. Most pool and spa motors use a Class “B” insulation.

15.ENCL (Enclosure): Common enclosures used include DP (dripproof) and TEFC (totally enclosed fan cooled). Most pool and spa motors feature a dripproof design, with “1081” features.

16.CODE: The NEMA code letter specifies locked rotor kVA per Hp (volts multiplied by locked rotor amps, divided by 1000 times rated HP).

17.SERIAL: The serial indicates the date of manufacture, which often appears as year/month combinations. Serial code information for each pool and spa motor can be found in guides and bulletins provided by the manufacturer (See p.55).

18.VOLTAGE DIAGRAM: This diagram provides information on the correct electrical connections to ensure proper operation of the motor.

19.WARNING: The warning at the bottom of the label re-emphasizes that voltage can be hazardous. Always TURN THE POWER OFF before working on a pool or spa motor.
