Other Features

Full Indicator Light

Illuminates when the bucket is ready to be emptied or when the bucket is removed from the unit for extended period. If bucket is replaced incorrectly, the light will stay illuminated.

Alarm Sound

If the bucket is full or missing for more than 3 minutes, an alarm will beep for 10 seconds to remind you to empty and/or replace the drain bucket.

Auto Shut Off

The unit will stop operation if the bucket is full or if the bucket is removed/ improperly installed.

Auto Defrost Mode

Through normal operation, frost may build on the evaporator coils. In this case, the compressor will power off while the fan stays running. You can usually tell if this is the case when the air exhaust emits cool air instead
of warm air.

Power Outage Restart

In the event of a power outage or interruption, the unit will automatically revert to the last settings you chose before the power outage and restart operations.

Choosing a Location

Place the dehumidifier on a smooth and level floor strong enough to support the unit with a full bucket of water.
Allow at least 18 inches of space on all sides of the unit for proper air circulation.
Close all doors, windows, and other exterior openings of the room to improve the dehumidifying effect.
Keep the air intake/exhaust clean and free of obstructions.
Avoid placing the unit in direct sunlight or in areas where the temperature goes below 40 °F or above 90 °F.
Humidity levels of 50-60% are optimal. Humidity levels above 60% may lead to mold or mildew growth.

Removing Collected Water

There are 3 options to remove water collected by your dehumidifier:

Option 1: Drain Bucket

Grab both sides of drain bucket and remove from unit following the arrow below. Removing the bucket just after stopping operation may results in drips of water on floor.
Empty the bucket by grasping the handle on top of the bucket with one hand while supporting the bottom of the bucket with the other hand.
After emptying, replace the bucket in the dehumidifier following the arrow direction below

Option 2: Gravity Drain Hose

Note:
Water can be automatically emptied into a floor drain by attaching a drain hose with a¾” inner diameter (not included), which attaches to a male nozzle on the left side of the unit.

Remove drain bucket from unit. Open drain cover door on right side of unit. Thread the¾” drain hose (not included) onto the nozzle. Replace drain bucket into the unit.
Position the gravity drain hose into the floor drain or other water receptacle. Ensure that the gravity drain hose is directed downward. If the drain hose is directed uupwardor horizontally, water will not exit the drain hose and instead will collect in the drain bucket.

Option 3: Internal Pump

Not all models have an internal pump feature. Please check your model number or contact customer support if you are unsure.

The internal pump can pump water up to 15 feet in any direction: vertically or horizontally. Water will still collect in the drain bucket during operation. As the bucket starts to reach maximum capacity, the pump will power on to remove water from the drain bucket.

If the pump feature is powered on and there is no drain plug or drainage hose in the drainage joint, water will leak from the drainage joint. If the pump feature is powered off while the unit is operating, water will not leak from the drainage joint. Please contact customer support if you have lost or misplaced your green drain plug.

Depress the gray plastic area using your fingertip or a small, flat object.
Step 2: While depressing the gray plastic area, remove the green drain plug.
Step 3: Insert the included drain hose into the drainage joint.

Cleaning

Before cleaning, turn off the dehumidifier and disconnect power cord from power outlet. Do not spray or douse the dehumidifier with water, and do not use volatile liquids (e.g. gasoline, paint thinner, etc.) to clean the dehumidifier.

White Plastic Exterior: Wipe down the plastic areas by using a soft rag dipped in warm, soapy water. Do not use harsh chemicals (e.g. bleach) or abrasive pads.

Air Intake Grille: Use a dust catcher or vacuum nozzle attachment.

Water Bucket: Every few weeks, you should clean the bucket to prevent the growth of bacteria, mold, and mildew. Partially fill the bucket with clean water and a mild detergent, and use a soft brush to scrub down the walls of the bucket. Do not use a dishwasher to clean the bucket, as this may warp the plastic. You will first need to remove the handle from the drain bucket.

Remove the handle by aligning the two ends of the handle with the openings on the drain bucket lid.
Remove the drain bucket lid by depressing the four (4) buckles on the drain bucket.
Remove the float from the drain lid.

Air Filter

After 250 hours of operation the Filter indicator light will illuminate on top of your dehumidifier. After cleaning the filter, place the Filter button again to reset the 250-hour timer. Do not forget to replace the filter before resuming operation. This may cause the evaporator coils to attract dust, which will harm the performance of your unit.

Clean the filter using warm, soapy water. Rinse thoroughly and air dry completely. Do not dry the air filter with a source of heat, such as a lighter or hair dryer, as this may damage the filter.

Filter access

Remove the drain bucket. The Filter is a light white plastic tab near the bottom of the air intake grille. Pull the filter straight down to remove it.

Frequently Asked Questions

Visit the complete list at www.tosotdirect.com/faq

Why does this unit give off heat?

Humid air is pulled into the dehumidifier and passes over refrigerated cooling coils. Moisture from the air collects on these coils then drops into the drain bucket. You dehumidifier emits heat because it takes a lot of energy to keep the coils refrigerated and the fan operating. The less humid your room is, the cooler it will feel, If your AC is set at 72°F it will operate more effectively at 50% humidity than 85% humidity.

Why is the fan running when the unit has already reached the target humidity I selected?

Your dehumidifier is in the automatic defrost mode. When moisture from the humid air collects on the cooling coils it can sometimes collect too rapidly and start to freeze. After your unit reaches target humidity the fan will continue pulling in the room temperature air to help defrost the coils. You can usually tell if this is the case when the air exhaust is emitting cool air instead of warm air. This tends to happen when the room temperature starts approaching 65°F, but your unit can still operate at temperatures around 40°F.
