It’s normal for the coils in dehumidifiers to frost. When this happens, the unit will go into auto-defrost mode. Once the unit has finished defrosting it will go back to the programmed settings. Frost can form on coils any time of the year but happens most frequently during season changes from autumn into winter.

It’s necessary for the oils in the compressor to settle before turning the unit on, not doing so can affect the performance of the unit.

Perfect Aire does NOT recommend using an extension cord with a dehumidifier, as it will pose a safety hazard. Dehumidifiers typically draw a lot of power, and using an extension cord that is not rated for the appropriate power load can result in overheating and potentially cause a fire.

Using an extension cord will void the warranty.

After having removed, cleaned, dried, and replaced the filter press the “Filter” button to turn the filter light off. This will reset the filter timer. The unit will indicate it’s time to clean the filter after 250 hours of running time.

In Comfort mode, the humidity is preset to run between 45-55%, this is based on the temperature of the room.

The recommended humidity for a space is 45~55%. This is dependent on what is in the space and what is comfortable for you. Anything above 55% is too humid and allows for the growth of mold and mildew in your home.

Several different factors could have caused the EC code. Please check the following on your unit: Check that the filter in the unit is clean Check that the room temperature is above 41 degrees Check that the humidity isn’t set too low, recommended humidity is 45~50% Make sure that the unit has plenty of space all around to allow for sufficient air circulation If the unit is sitting on a concrete floor elevate the unit a few inches off the floor Turn off and unplug the unit for 4-6 hours If the above doesn’t resolve the issue please contact Consumer Support at 844-472-2473.

P2 or Eb means that the bucket is full or that the bucket has been removed. Remove the bucket from the unit. Check that the float and foam have not been removed from the bucket and that the float isn’t broken. In the compartment where the bucket sits, there will be a silver or white tab to either the left or right, depending on the location of the float. With the unit on, press and hold the tab. If the P2/Eb error code goes away, then the tab needs to be slightly bent forward. This will allow for better contact with the float. If the P2/Eb error code does not clear, the internal switch is defective.

The mesh upper back panel is the air filter of most dehumidifiers; There will not be a separate filter located behind the back panel. If your dehumidifier has PAD in the model number, the filter will be located on the front upper portion of the dehumidifier, it will slide up to be removed.

Check the filter and make sure that it isn’t cracked, bent, or torn. For models with a front slide-out filter and if the filter is in good condition, remove the filter and check the water reservoir for a black plastic cover about 1″ x 2″. With a flashlight, from above the filter opening, look to see if anything is blocking the path. Look through the front grill starting at the top right-hand corner about 1/3 of the way down. You will see a box that is 1″ x 1″ X 2″ attached to the coils, this is the sensor box. Make sure that the box has a cover. If you find the cover inside where the filter goes or in the water reservoir use the pictures provided to reattach the cover and box to their proper location on the coils.

Check that the hose connection is secure and that there aren’t any kinks or blockages in the hose. The hose should always slope downward not go vertically or in an upward direction. If the hose is clean and water flows out freely, check the placement of the unit. The unit not being level could be another factor as to why it’s collecting water in the bucket and not out of the drain hose. Make sure that the unit is level. If there is a slight slope to the floor, adjust the unit so that the hose is closest to the drain. In units that were stored for the winter, for an extended period, or in a highly dusty area, there may be grime build-up in the main water outlet that connects to the drain accessories. Use a pipe cleaner to help clear the buildup by inserting the pipe cleaner in the main water outlet.

It is normal for the unit to produce heat. As humidity is passing through a dehumidifier, it is designed to remove moisture from the air. After this process is complete, the air free of moisture is reheated and released as dry air. The rise in temperature is also due to the compressor running.
