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.
