Azure is an electronically controlled motor (ECM) that replaces a multitude of applications. Two motors cover ratings from 1/8 HP to 1/3 HP at 208-230V 825/1075 RPM and 1/3 HP to 1/2 HP 208-230V 825/1075 RPM and CW or CCW. These motors are simple to install. The Azure condenser fan motors connect the same as a standard PSC condenser fan motor, BUT WITHOUT the capacitor. Just plug the motor into a 115V power source (using supplied programming cable) and select 1 of 4 operating modes and then install the motor: 1) 1075 RPM CW (LE) - Factory Default 2) 1075 RPM CCW (LE) 3) 825 RPM CW (LE) 4) 825 RPM CCW (LE) Unlike other ECM motors, an outboard surge protector is included with the Azure wiring harness. This is a replaceable device that is much less expensive to replace than replacing the entire motor in the event of a power surge.
