Bucketless Dehumidifier Frequently Asked Questions 

During what time of the year should I run my dehumidifier?

It depends on the level of humidity control you need. 

* If you live in a northern climate and have forced-air heat, you probably don't need to run it year around. 
* If you live in a southern climate with the air conditioner running continuously, you probably don't need a dehumidifier at all. 
* If you have a damp cellar or basement--or an area of the house where you want little or no humidity--you may have to run the unit year around. 

My drain hose does not fit.

Please ensure that the hose is placed over the drain port which is located directly underneath the hose hooks.

Is it normal for my unit to run continuously?

If your dehumidifier is running constantly and the water container is not filling up at least once a day, there may be a defect with the dehumidifier. But if the unit runs constantly and the water container has to be emptied daily, there's just a lot of humidity in the room and the dehumidifier is doing what it's supposed to do.

How do I know what setting to use with my dehumidifier?

We suggest that you buy a separate, good-quality hygrometer to determine the actual moisture content of the air in the room you want to control. Then, with a bit of experimentation, you can set the humidistat on the dehumidifier so that it cycles off when it reaches the humidity level you want to maintain.

How does my Royal Sovereign dehumidifier work?

A fan pulls room air over two sets of refrigerant-filled coils, one cool and the other warm, wringing out moisture along the way. The water that condenses out of the air drips into a reservoir inside the dehumidifier. When the reservoir is full a pump will push the water out a tube.

What does error Exx mean?

E1 is Humidity sensor error

E2 is Defroster sensor error

Why does my dehumidifier ice or frost up?             

The room is too cool; dehumidifiers remove moisture from the air by chilling a set of coils and allowing the moisture in the air to condense on them. If the room temperature is too cold, the moisture can freeze. To prevent ice-up, you may need to either raise the dehumidifier to a higher (warmer) location or increase the temperature of the room.

The coils you see on the back of your dehumidifier are the evaporator coils. When the unit runs, the coils get very cold. As the fan draws the room air over the coils, the humidity in the air condenses out of the air onto the cold coils. But, if the temperature of the air the fan draws over the coils is too cool, the humidity that condenses out of the air freezes on the coils. 

To remedy this problem, you can try any of these: 

* Warm up the room the dehumidifier is in. 
* Put the dehumidifier on a sturdy table (the room air is coolest near the ground). 
* Turn the unit off until the room warms up. 

Why does my unit run, but no air blows out the front?

Your dehumidifier has a circulating fan that draws the room air over the coils. If there's no air movement out the front or back of the unit, the fan motor may be burned out or stuck, or the fan blade may be broken. If so, you need to replace the fan motor or the fan blade.

Why does the fan keep running even though the compressor is off?

This is normal for the Royal Sovereign dehumidifier, it is to keep air circulating throughout the room.

Why do I need a dehumidifier?

A dehumidifier can turn air from clammy to comfortable or keep a damp basement dry. Dehumidifiers are ideal for cool, damp basements or crawl spaces.
