How do I set up the internal pump?

Watch our video guide!

1. Power the pump feature on using the display screen on top of your unit.

2. Locate the hose connection on the lower-right rear of the unit.

3. To connect the included drain hose, simply push in on the gray area with the tip of your finger while pulling the green plug out of the hole. (Note: Do not yank or use extreme force to remove the plug as this may damage the unit. The plug should slide out easily while depressing the gray collar.)

4. After removing the green plug, insert the hose into the hole while holding down the gray area with your finger.

My pump isn't working. The bucket just fills up with water. Help!!!

Don't worry! In order to save power, the internal pump does not run constantly. The pump will begin to run once the drain bucket approaches maximum capacity. No additional action is required from you, the pump will turn on by itself.

Does the unit turn off when the bucket is full?

Yes, the automatic float switch inside the bucket turns the unit off when the drain bucket fills up.

Does this unit have a removable tank or bucket?

The unit has a removable drain bucket located on the bottom portion of the front of the unit. When the water level reaches a high point, the float sensor will auto-stop the dehumidifier and prevent the bucket from overfilling. The water can be removed by sliding the bucket towards you and using the handle to carry and empty the bucket.

How heavy is the bucket of water when full?

A completely full drain bucket on the 20 Pint model weighs approximately 8lbs, 12lbs for the 35 Pint model, and 15lbs for the 50 Pint models.

Do you need to turn off the unit to remove the bucket?

After removing the bucket a sensor will turn the unit off until the bucket is mounted back into place. However, we recommend shutting the unit off to prevent any leakage after removing the bucket.

Can this unit be used for continuous drainage?

Absolutely! You simply need to attach any standard ¾” hose to the drain outlet on the left side of the unit (when looking at it from the front.) Run the ¾” hose into your floor drain or sink and the machine will run constantly.

Will water go back up the drain hose if the hose end is higher than the drain?

If the drain hose is higher than the drain outlet, the dehumidifier will instead use the drain bucket. The drain hose is gravity-fed, so it must be lower than the drain outlet on the unit.

How do you set up the drain hose?

Once you attach a hose on the left side of the unit, the water should drain smoothly as long as it's installed properly. The hose has to be at a downward angle, otherwise water will collect in the bucket instead.

Can we use a garden hose as a gravity drain hose?

Yes, that is the recommended type of hose for gravity drainage. Just make sure it has a ¾” female connection.

What hose size is needed?

-A standard US garden hose at 3/4 inches for gravity drainage.

-The included tube hose with 0.6cm(0.24 inches) external diameter and 0.4cm(0.16 inches) inner diameter for the built-in pump.

The pump is not working. Water goes into the drain bucket. Why?

If you have connected a hose to the internal drain pump outlet and have activated the pump mode on the control panel, water will collect in the drain bucket until the bucket is nearly full. Then the pump will automatically remove the collected water for you.

Can I drink the water from the bucket?

We do not recommend you (or pets) drink any water from the dehumidifier. You could use the water in the bucket to water your non-edible plants and flowers, however.

Can this unit pump water vertically?

Yes, our 50-pint with internal pump will automatically pump the water up to 15 feet away whether the hose is horizontal, vertical, or, spiral.

Will a dehumidifier help the air conditioner cool the air?

Yes, the portable dehumidifier helps the A/C in your home. Dehumidifiers can reduce the humidity out of the air allowing your A/C to work less often and more efficiently, saving on your energy bill and making your environment more comfortable.

Can this unit replace my house central air system?

A dehumidifier is a great air treatment solution for removing excess moisture around your home and protecting it from damaging mold and mildew. It is enough for some places like a basement, but maybe not the entire house with many floors or levels. Dehumidifiers work by producing heat, so it cannot be used to cool your hoom like an air conditioner would.

Does this dehumidifier need filters?

No, TOSOT dehumidifiers use a reusable filter that should be cleaned every 30 days of operation. Trouble locating the filter? Please check this link for guidance.

Does this dehumidifier put off heat?

Yes, this unit does exhaust hot air. There is no dehumidifier on the market that will not emit heat because that is how they are able to remove humidity.

In short, warm air is pulled into the dehumidifier and then passes through refrigerated cooling coils. The moisture from the air forms on these coils and drops into the drain bucket (or through the drain hose if you selected that option). Your dehumidifier emits heat because it has to power the fan and cooling elements at the same time, which draws considerable energy compared to a standard fan.

Does it come with a hose?

An internal pump hose is included with models that have an internal pump. A ¾” hose for the gravity drain is not included and must be purchased separately.

What is the decibel levels of each unit and settings?

The 70-Pint dehumidifier operates at 52/50/48 decibels on the high/medium/low settings. For reference, a decibel rating of 45 or under will be virtually silent. Decibel levels between 45 and 50 sound similar to light rainfall. Ratings of 50 or above will be equivalent to the level of a quiet conversation.

The unit turns off every few hours, why?

The dehumidifier only runs when the humidity levels are outside of the set humidity target. Other possible reasons your unit is not running is the water level is high and bucket needs to be emptied, or the compressor coils are freezing and the auto-defrost function is in effect.

What is the minimum temperature the unit can operate in?

41 Degrees Fahrenheit. Temperatures lower than this may cause the compressor coils to freeze over.

Does this machine automatically reset if power goes out?

Yes, in the event of a power outage, the unit will power back on when power is back online.

Can I trust this to continuously working for one week without supervision?

Yes, if: 1) Humidity is in the air. 2) If the unit is connected to a power source. 3) If a gravity drain hose is connected downward towards a drain.

Does this unit have a timer?

Yes, the unit has a timer. You can check the user manual for details on how to set up the timer

What is the difference between the 30, 50, and 70 pint units?

The different measurements are for the maximum amount of water the unit could remove from the air in a 24 hour period in normal conditions.The unit may remove slightly more or less than the posted amount (20, 35, 50 pints) depending on the actual RH and temperature.

Can I turn off the indicator light?

No, you can not turn off the light when the unit is running. Once the unit is power off, the light will turn off.

How does the timer work? Can I set the delay-off and delay-on at the same time ?

The timer function only allows one program selection which means you can only set a delay-on or delay-off at one time.

Press the timer pad when the machine is on, you can set it to turn off automatically in 2 or 4 hours. Press the timer pad when the machine is off but plugged in, it will turn on in 2 or 4 hours

Can I use vinegar in the water bucket to have the bucket and drain hose cleaned?

Yes, you can put some vinegar in the water bucket.The proportion of water to vinegar is up to you as the plastic material won't be affected by the vinegar.

Can I use the dehumidifier on the carpet or a rug?

The main concern is that there is a fire hazard when placed on a carpet. If the heat dissipation is not good, the dehumidifier will become hot after running for a long time. You should place a solid, flat material (wood, metal, plastic, etc) under the unit to help ensure heat dissipation.

Why is my new DOE 35 Pint dehumidifier smaller size than my previous 50 Pint?

The new DOE 35 pint was redesigned with improved organization of the compressor, fan, and air channel, which allows for a more compact size. Only the internal organization is redesigned, the internal components of our dehumidifiers have not changed that much. The new 35 Pint and the previous 50 Pint perform the same.

How long is the defrost cycle?

The unit has an automatic defrost switch which is engaged whenever needed based on temperature. Cycle times are not exact and depend on each situation.

Is the unit durable?

The units can endure non-stop use. Quality compressors are the dehumidifier’s biggest concern. Larger units have larger compressors and do not work as hard as their smaller-compressor counterparts, so a larger capacity unit may last longer than a smaller-capacity unit.

What is the length of the cord?

The cord is 5 feet in length from base to plug-in.

What size should I order?

Variable factors determine ideal dehumidifier size: 1) RH% (relative humidity percentage) how humid or moist is your room typically. 2) Size of area: 1500 sq ft, 3000 sq ft, or 4,500+ sq ft. If in doubt, go with the larger option. You can check out our guide for selecting a dehumidifier here .

Does the 50 Pint draw more moisture out than a 35 Pint?

Yes, the 50 Pint model has a larger size compressor than the 35 Pint, so it is able to remove more moisture per day (15 pints more to be exact!).

How does the Energy-saving mode run? The unit seems never shut off in the ES mode?

When entering the Energy-saving mode in the cooling mode, the compressor will stop, while the fan will keep running for 3 minutes and then stop for 10 minutes.

Later, the fan will run again for another one minute and then stop for 10 minutes.

Then, the fan will run again for another minute and then stop.

Meanwhile, if the room temperature is higher than the set temperature, the compressor and the fan will be turned on together and start cooling again.

The unit is not cooling if only the fan runs, but the sound may make you feel like the unit never shuts off. Actually, the fan setting can help control the cooling effect (air exchange) and will not cause a lot of consumption.

Can the window air conditioner be mounted vertically or sideway instead of horizontally?

No, the unit has to installed horizontally, which can prevet any collected water from flowling back to the compressor.

Do I really need to run this for 24 hours after installing it, as the manual says?

The user manual suggests you run the unit for 24 hours to ensure that the machine is functioning well during long-time operation. You can adjust the testing time to 8 hours or even less.

How does the sleep mode work?

When entering sleep mode in cooling mode, the temperature will rise by 2°F after a one-hour operation, and keep increasing by 2°F each hour. Then, the unit will stay when reaching the upper-temperature limit, 86°F. For example, if the original set temperature is 85°F, after an hour, it can only reach 86 but not 87, and then stay at this temperature.

Is that normal that the air conditioners would cycle on and off?

Our AC is a fixed frequency air conditioner, when the unit detect that the room is cool enough(by temperature sensor), the compressor will power off, i.e. the unit will not stay on, to save energy and control the temperature not go down. When the temperature starts to rise a few degrees above your target setting, the compressor will power back on.
