WARNING! Risk of contact with high-speed rotating fan blades. Can cause serious injury or death. Open all
local and remote electric power-supply disconnect switches, verify with a voltmeter that power is off, and
verify that all fan blades have stopped rotating before working in the unit cabinet or on the fan assembly. If
control voltage is applied, the fan motor can restart without warning after a power failure. Do not operate the
unit with any or all cabinet panels removed.
CAUTION: Risk of contact with hot surfaces. Can cause injury. The compressor, refrigerant discharge lines,
fan motor, and some electrical components are extremely hot during unit operation. Allow sufficient time for
them to cool to a touch safe temperature before working within the unit cabinet. Use extreme caution and
wear appropriate, OSHA-approved PPE when working on or near hot components.
CAUTION: Risk of improper moving, lifting and handling. Can cause equipment damage or injury. Only
properly trained and qualified personnel should work on this equipment. Condenser fan modules weigh in
excess of 125 lbs. (56.7 kg). Use proper lifting techniques and wear appropriate, OSHA-approved PPE to avoid
injury and dropping the fan module during removal. Equipment used in handling/lifting, and/or installing the
fan assembly must meet OSHA requirements. Use handling/lifting equipment rated for the weight of the fan
assembly. Use ladders rated for the weight of the fan assembly and technicians if used during installation.
Refer to handling/lifting, and/or installation equipment operating manual for manufacturer's safety
requirements and operating procedures.
NOTE: If at any time a parameter is entered and the condenser display does not show 888 or if the display shows Err,
re-enter the parameter. If the display still shows Err after ENT is pressed, power cycle the control board by
unplugging P24, waiting 15 seconds and plugging P24 back in. Contact the factory if the parameter still displays Err
after ENT is pressed.
To replace the fan:
1. Turn Off power to the unit using the disconnect.
2. Use a voltmeter verify that voltage is no longer present at the unit. Wait a minimum of 10 minutes to allow the
EC fan capacitors to discharge before proceeding.
3. Remove the fan cover, disconnect electrical connections internal to the EC fan and remove the cable glands
from the EC fan to be replaced; See Figure 8.4 on the facing page, and Figure 8.5 on page 50.
