WARNING: ALWAYS
DISCONNECT MAIN
HVAC SYSTEM
POWER BEFORE
DISCONNECTING OR
RE-CONNECTING
ANY WIRES OR
CONNECTORS TO THE
EVERGREEN MOTOR.
1. Disconnect the main power to
the HVAC system.
2. Disconnect the High Voltage
SIGNAL connection(s) from the
motor to the HVAC system.
3. Reconnect the main power to
the HVAC system. Confirm there
is proper voltage to the High
Voltage POWER connections on
the motor.
4. Energize any of the Low Voltage
SIGNAL (speed) tap selections
continuously for a minimum of
5 minutes.
5. Disconnect the main power to
the HVAC system for a minimum
of 1 minute. Confirm there is
no voltage to the High Voltage
POWER connections on the
motor. During this time
reconnect the High Voltage
SIGNAL connection(s).
Now the Rotation Sensing feature
will operate as described on page
23 “Rotation Sensing”. If the motor
does not perform the Rotation
Sensing feature, repeat this
procedure carefully and confirm
all timings with a watch.
If the motor again selects the wrong
direction, confirm that the selected
Evergreen IM is not too large for the
system. See the selection chart on
page 30. If the motor has not been
sized properly, replace the motor.
If the motor meets the selection
criteria please call the Evergreen
Hotline at 866-503-8566.
