If not, replace!

Check if the exhaust and supply filters are clean and make sure they

do not prevent air flow!

Make sure the drain hose is connected and check for any blockages 

through the drain line! If needed, clean it!

Please check that the duct dimensions used in the duct system are

the air temperature to -8 °C or above.

Check for unusual noise or vibration after the installation. If there
