What to do if the SystemAir DKEX 225-4 Fan motor does not rotate?
If the SystemAir Fan motor does not rotate, check the power supply, replace any defective components, and reconnect it. Also, ensure the electrical connection matches the wiring diagrams. Allow the motor to cool and reset the motor protection if it has overheated, identifying the cause of overheating. For 3-phase motors, verify that no phase is missing.
Why is the air output not sufficient in my SystemAir DKEX 225-4?
To address insufficient air output from your SystemAir Fan, ensure the electrical connection is correctly done and agrees with the wiring diagrams. Make necessary changes in the duct system and installed components to increase the air pressure. Adjust the airflow shutters, remove any blockage in the air inlet or duct system and make sure that the product is applicable for the installation location.
What to do if electronic components or the motor is overheated in SystemAir Fan?
If the electronic components or the motor of your SystemAir Fan is overheated, allow the motor to cool, reset the motor protection, and identify the cause of overheating. Ensure the product is suitable for the installation location, considering both motor overload and ambient temperature. Also, verify that there is sufficient space around the motor to maintain adequate cooling.
What to do if thermal contacts, PTC or resistors are released in SystemAir Fan?
If the thermal contacts, PTC, or resistors are released in your SystemAir Fan, ensure the electrical connection is correctly done. For a 3-phase motor, verify that no phase is missing. Check the motor cooling impeller and, if possible, measure the resistance to check the motor winding. Connect the capacitor correctly, referring to the included motor wiring diagram.
How to fix a SystemAir DKEX 225-4 Fan that does not operate smoothly?
If your SystemAir Fan does not operate smoothly, make sure the product is correctly installed and check the duct system. Increase or decrease the fan speed until the product operates smoothly. Ensure that the temperature of the transported air is not higher than the value on the name plate and replace the product.
Why does the fan speed not get the nominal value in my SystemAir DKEX 225-4 Fan?
If the fan speed of your SystemAir Fan does not reach the nominal value, measure the resistance to check the motor winding, if possible. Set the speed control correctly. Remove any mechanical blockage preventing the fan impeller from turning freely. For a 3-phase motor, ensure that no phase is missing.
