💡 Technician Notes

• Inspect the blade for cracks, warping, or edge chips before installation to prevent imbalance and vibration.

• Confirm the blade’s rotation direction matches the unit’s airflow orientation.

• Torque the shaft clamp to the OEM specification (approximately 20 in-lb) to avoid slippage without overstressing the clamp.

• Clean any debris or residue from the condenser housing to maintain unobstructed airflow.

• After installation, run the unit and listen for unusual vibrations—small blade imperfections can amplify noise at speed.
