Tips for First-Time Use
1. Allow the unit to sit upright for at least 3-4 hours before
powering on. Shipping carriers may set the unit on its side,
which causes the refrigerant to pool in certain areas.
Standing the unit upright for 3-4 hours allows the refrigerant
to move freely within the coils.
2. Run the unit continuously for 24 hours after letting the unit
to stand upright for 3-4 hours. This allows the unit to work
out any "kinks" that may have resulted during shipping from
our factory or to your doorstep.
3. If you have any questions, please email us at

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
* 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
Option 1: Drain Bucket
Step 1: 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.
Step 2: Empty the bucket by grasping the handle on top of the bucket with one
hand, while supporting the bottom of the bucket with other hand.
Step 3: After emptying, replace the bucket in dehumidifier following the arrow
direction below
Option 2: Gravity Drain Hose
Water can be automatically emptied into a floor drain by attaching a drain hose
with a 4" inner diameter (not included) which attaches to a male nozzle on the
left side of the unit.
Step 1: Remove drain bucket from unit. Open drain cover door on right side of
unit. Thread the %" drain hose (not included) onto the nozzle. Replace
drain bucket into the unit.
Step 2: Position the gravity drain hose into the floor drain or other water
receptacle. Ensure that the gravity drain hose is directed downwards.
If the drain hose is directed upwards or 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.
Step 1: Depress the gray plastic area using your fingertip or a small, flat object.
= y
Step 2: While depressing the gray plastic area, remove the green drain plug.
© =
Step 3: Insert the included drain hose into the drainage joint.
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.
Step 1: Remove the handle by aligning the two ends of the handle with the
openings on the drain bucket lid.

Step 2: Remove the drain bucket lid by depressing the four (4) buckles on the
drain bucket.

Step 3: 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 war, 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.

Frequently Asked Questions
Visit complete list at
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 already reached the target humidity
| 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 to temperatures around 40 °F.
What happens if my unitisn't working? Does my unit have a warranty?
Please contact us at [email protected] if you have any questions
about your unit. If you haven't already done so, you will be asked to register
your product for warranty on our website. You can speed up that process by
visiting to give us some information about your
unit. All products are covered under a one year warranty from the date you
place your order.
