Mars Azure 10875 Installation Instructions

Azure

Product Description

These Azure motors are high efficiency 5.5" HVAC condenser fan motors (ECM) suitable for 208-230V applications
®
up to1/2 HP. An internal microprocessor determines power output necessary for the load. They DO NOT require
a capacitor. The Motor rotation direction is field adjustable by applying 115V to the motor using the enclosed
programming cable. When 115V is applied, the motor will cycle through 2 options for rotation. When the 115V
power signal is removed, the motor will be set at the rotation that it was running when the power was removed.
10872
Voltage:
208-230
Rotation:
CW or CCW
RPM:
1075 RPM (single speed)
HP:
1/3 - 1/2
Capacitor: NOT REQUIRED
Orientation: Horizontal
Efficiency: 85% Peak
IMPORTANT: Do not use Current (Amps) as a basis for determining motor efficiency. Due to a low Power Factor, EC
motors can have the same Current draw as standard motors, yet their power consumption (Watts) is significantly less.
To prevent electric shock, personal injury, or death, turn off the electric power at the disconnect or main service panel prior to
making any electrical connections.

Set-up / Installation:

Perform the following procedure BEFORE mounting the motor and BEFORE attaching the surge protector and fan
blade.
1) Set the motor speed and rotation by connecting the programming cable (115V power cable with connectors and
plug) directly to the motor harness as follows:
• BLACK programming lead to BLACK motor power lead
• WHITE programming lead to BROWN motor power lead
• GREEN programming lead to GREEN/YELLOW motor ground lead
2) WITHOUT THE FAN ATTACHED, plug the programming cable into a 115V power source. The motor will cycle
through 2 representative modes of operation over the period of approximately 30 seconds. When the motor cycles
to the desired operating mode, remove the 115V power source. The internal microprocessor will set the selected
speed and rotation. NOTE: In the event an error is made and the rotation requires changing, the programming
procedure can be repeated and the program will be overridden.
