Installation Instructions

Positioning the Unit

A dehumidifier operating in a basement will have little or no effect in drying an adjacent enclosed storage area, such as a closet, unless there is adequate circulation of air in and out of the area. (See Fig. 13)

Do not use outdoors.
This dehumidifer is intended for indoor residential applications only. This dehumidifier should not be used for commercial or industrial applications.
Place the dehumidifier on a smooth, level floor strong enough to support the unit with a full bucket of water.
Allow at least 8” of air space on all sides of the unit for air circulation (at least 16” for air outlet).
Place the unit in an area where the temperature will not fall below 41°F (5°C). The coils can become covered with frost at at lower temperatures, which may reduce performance.
Place the unit away from any clothes dryer, heater or radiator.
Close all doors, windows and other outside openings to the room.

Care and Cleaning

Turn the dehumidifier off and disconnect the plug from the power source before cleaning.

Clean the Grill and Case

Use water and a mild detergent. Do not use bleach or abrasives.
Do not splash water directly onto the unit. Doing so may cause an electrical shock, cause the insulation to deteriorate, or cause the unit to rust.
The air intake and outlet may get dirty during operation, use a vacuum cleaner or brush to clean.

Clean the bucket

Every few weeks, clean the bucket thoroughly to prevent growth of mold, mildew and bacteria. Partially fill the bucket with clean water and mild detergent. Swish it around in the bucket, empty and rinse.
Note: Do not use a dishwasher to clean the bucket.

Clean the air filter

To remove the filter, pull filter outwards (See Fig. 14).
Wash the filter with clean water then dry.
Re-install the filter, replace bucket.

DO NOT operate the dehumidifier without a filter to avoid loss of performance and damage to the unit.

Clean the unit, water bucket and air filter.
Wrap the cord with the power cord buckle.
Cover the unit with a plastic bag.
Store the unit upright in a dry, well-ventilated area.

FAQ’S

Do dehumidifiers use a lot of electricity?

Yes. Dehumidifiers use a lot of electricity. While the wattage (483.24W is average) and the hourly electricity usage (0.427 kWh is average) are not substantial, the long duration of use results in dehumidifiers consuming a considerable amount of electricity.

What are the disadvantages of a dehumidifier?

Disadvantages of dehumidifiers
they can make quite some noise.
might not work in low temperatures.
needs regular maintenance.
can be quite large and heavy.
uses electricity constantly, therefore;
increases energy bill.
purchase costs are around $200.
windows and doors need to be closed.

Can I use dry mode all day?

Dry mode will not remove 100% of the moisture in the air. Instead, it will help lower the humidity to a healthy level. However, it’s recommended not to run your AC on dry mode for more than 1-2 hours at a time to avoid drying the air too much.

Why is my Midea dehumidifier leaking water?

It may seem like an obvious issue, but more often than not, a leaking dehumidifier is caused by a disconnected drainage hose. For new units, this often occurs because the drainage hose was never hooked up in the first place. But it is also possible for a functioning hose to become disconnected or loosened over time.

Can a dirty filter cause a dehumidifier to leak?

The following possible issues that can cause this are; dirty air filter, dirty evaporator coils, the dehumidifier being set to operate at too low of a temperature for an extended time, and not enough refrigerant in the compressor.

Why do dehumidifiers start fires?

About 2 Million Dehumidifiers In The U.S. Have Been Recalled Over Possible Fire Hazard : NPR. About 2 Million Dehumidifiers In The U.S. Have Been Recalled Over Possible Fire Hazard The Consumer Product Safety Commission has recalled dehumidifiers made by New Widetech because they can overheat and catch fire.

How do I know if my dehumidifier is working properly?

If you’re not sure whether your dehumidifier is working, you can always approach it, place your hand above it, and feel for airflow. Some models have different settings, so there’s a chance that you’ve set yours at low operating speeds, making it hard to see if it’s doing its job.

Can you leave dehumidifier on overnight?

Yes, we recommend using a dehumidifier 24hrs, however, be aware that there will always be a noise generated from the machine when it is operating.

Will dehumidifier work with windows open?

The windows in a room should be kept closed when running a dehumidifier. As open windows let moisture in from the outside, they can work against the dehumidifier and keep the room from drying out because the continuous flow of air can be counterproductive.

Why are my bedroom windows wet in the morning?

The reason it happens is because the external air is warmer than the temperature of the glazed pane’s surface – and the dew point of the air is higher. It is more likely to occur at night or early in the morning when temperatures are low, particularly if there is a clear sky and almost no wind.

Why do dehumidifiers fail so quickly?

Dehumidifiers contain electrical components that can go bad, in addition to internal wiring that can short or come loose from connection terminals. Models made within the past decade or so might contain electronic control boards that can burn out and stop working.

Why is my dehumidifier running but not collecting water?

If your dehumidifier is not collecting water, the unit is not operating properly: Try resetting the dehumidifier by disconnecting power to the unit for 30 seconds and re-connecting the power. Then, set the control settings and see if the unit operates properly.
