Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other
appliances.
Do not repair, disassemble and/or modify the unit by yourself.
Always turn off the appliance when cleaning the air filter, and transporting.
Do not turn this appliance on and off by plugging and unplugging. Always use the ON/OFF switch.
Do not drink or use the water collected or drained from the appliance.
Do not remove the water bucket during operation.
Transport the unit in an upright position only, or leave it in an upright position for at least 2 hours
before first use.
This appliance must be installed in an area protected from the element, such as wind, rain, water
spray or drips.
When using this appliance in confined spaces, such as closets, be sure to keep doors open to allow
proper ventilation to prevent overheating and fire.
The unit should not be located next to ovens, grills or other sources of high heat.
Always place the unit on even and hard and level surface.
Do not sit or place objects on the unit.
Do not allow children to climb, stand or hang on the appliance. The unit could tip over and get
damaged and seriously injure somebody.
Ensure curtains or other objects are not obstructing the air intake and exhaust.

Do not, under any
circ ums tances , cut ,
remove, o r bypas s
the grou ndi ng prong.
This unit is gro unded through the
power cord plug whe n plugg ed
into a ma tching wal l outlet.
Electrical Information
The appliance is equipped with a three-prong grounded plug
on the power cord for your protection. Never modify,
remove or attempt to repair the plug yourself.
Do not pull the unit by the power cord or pull on the cord to
unplug the unit. Grip the plug and pull it away from the wall
receptacle.
Ensure the power cord is not tangled, knotted or otherwise
distorted before operating the unit.
The dehumidifier must be plugged directly into a properly
grounded wall outlet receptacle. If the wall receptacle you
intend to use is not adequately grounded or protected by a
time delay fuse or circuit breaker, have a qualified
electrician install an outlet that is appropriate to local
electrical codes and requirements.
Do not use extension cords, power strips or an adapter plug
with this unit
Always unplug the unit before opening, installing or servicing.
How it Works
When the dehumidifier is started, the fan begins to pull moisture-laden air across the dehumidifying
coils. The coils condense or draw moisture from the air, and air flows through the side louvers into the
room as dry, warm air. Moisture removed from air is collected in a water bucket on the front of the
dehumidifier.
The unit is designed to operate between 41°F (5°C), and 96°F (35°C). The "Compressor" circuit has
an automatic 3 minute time delayed start if the unit is turned off and on quickly. This prevents
overheating of the compressor and possible circuit breaker tripping. Make sure the tank is fitted
correctly otherwise unit will not turn on.
Energy Saving Guide
This Whynter dehumidifier is an Energy Star rated appliance. Follow the guide below can help to get
the best performance and efficiency from your dehumidifier.
Do not cover the air intake and outlet.
Do not place the unit in front of curtains or drapes- to ensure they do not obstruct the air
intake.
Keep curtains, blinds or drapes closed during the sunniest part of the day.
Close all windows and doors.
Indoor relative humidity should ideally be kept between 35%RH and 60%RH depending on the
ambient temperature.
Make sure the unit is on a hard and level surface.
To prolong the compressor's life, please wait at least 3 minutes before turning the unit back on
after shutting it off.
Inspect and keep the air filter clean by cleaning regularly.
Perform routine maintenance.

OPERATING YOUR DEHUMIDIFER
This dehumidifier is intended for indoor residential
applications only and should not be used for commercial
or industrial applications.
Place the dehumidifier on a smooth, hard and level floor
strong enough to support the unit with a full bucket of
water.
Do not attempt to roll the unit over objects.
Avoid placing the unit in an area where the temperature
will not fall below 40F. The coils may become covered
with frost at temperatures below 40F and may reduce
performance.
Do not place the unit near clothes dryer, heater or
radiator.
The dehumidifier must be operated in an enclosed area.
Shut all doors, windows and openings to your target
dehumidifying space for maximum performance
Allow at least 10” of air space on all sides of the unit for
good air circulation.
NOTE:
When using the dehumidifier for the first time, operate the unit continuously for 24 hours.
This unit is designed to operate in environment between 41°F and 95°F.
Dehumidifiers working in a basement will have little or no effect on adjacent enclosed rooms such as closets,
unless there is enough circulation of air in and out of the enclosed area.
If the unit has been switched off and needs to be switched on again, allow approximately three minutes for the
correct operation to resume.
Select a suitable location and make sure you have easy access to the electrical outlet.
Ensure the air filter and water bucket are correctly installed before switching the unit on.
Always be careful when moving the unit with a full water bucket.
Ensure that the safety requirements and warnings detailed in this user manual are followed when operating
this unit.

Removing the collected water
There are two ways to remove the collected water.
1. Manual drain
When the unit is off and the bucket is full, the unit will
beep 8 times and the Bucket Level indicator light will
flash, the digital display will also indicate P2.
When the unit is on and the bucket is full, the
compressor shuts off but the fan runs for an
additional 30 seconds to dry any moisture on the
condenser. The unit will then beep 8 times and the
Bucket Level indicator light will flash, the digital
display will also indicate P2.
Slowly pull out the bucket. (Fig 5) Grip the left and
right handles securely, carefully pull the bucket out
to prevent water spillage. (Fig 6) Do not put the
bucket on the floor as the bottom of the bucket is
uneven and it may tip.
Dispose the water (Fig 7) and reinstall it to the
dehumidifier. The bucket must be installed securely
for the unit to operate.
The unit will restart when the bucket is restored in its
correct position.
NOTES:
When the bucket is removed, do not touch any parts
inside of the unit. Doing so may damage the unit.
Be sure to push the bucket gently all the way into the
unit. Hitting the bucket against anything or failing to
push it in securely may cause the unit to malfunction.
When the bucket is removed, check if there is any
excess water at the base of the unit. Wipe any visible
water inside the unit before replacing the bucket.
2. Continuous drain
Water can be automatically emptied into a floor
drain by attaching the unit with a water hose( 24mm)
(included).
Remove the water bucket from the unit and set
aside.
Lift up the Darin Hose Outlet cover located on the
right side of the unit (Fig.8)
Insert the female threaded end of the hose to
the Drain Hose Outlet. (Fig.9a)
Grip the hose from inside the unit and screw the hose
onto the threaded portion of the tray located in the
bucket opening.(Fig.9b)
Make sure the hose is securely fastened to prevent
leakage. Direct the hose toward a drain or other suitable
drainage outlet. Make sure that there are no distortions
with the hose that may stop the water flow.
Reinsert the water bucket back in the unit and make
sure that it is inserted securely.(Fig.9c)
Select the desired humidity setting and fan speed on
the unit for continuous draining to start.
NOTE: If the unit stops operating, check if the Bucket
Level light is illuminated. If it is, remove the bucket and
empty the water and then check the seal between the hose
and the drip tray. If there is a leak, replace the hose gasket
and re-tighten the hose.
1. Pull the bucket out carefully.

Use a vacuum cleaner or tap the filter lightly to remove loose dust
and dirt.
Rinse the air filter under warm or cold running water
(no hotter than 100F.)
Dry thoroughly before reinserting the air filter.
Reinstall the air filter and replace bucket securely.
CAUTION:
NEVER operate the dehumidifier without an air filter in place.
4. End of Season Storage
After turning off the unit, wait 24 hours before emptying the bucket to allow excess moisture to drain
into the bucket.
Clean the main unit, water bucket and air filter as detailed above.
Wrap the cord around the power cord bracket (Fig.12a) or wrap the cord and secure it with the
power cord strap (Fig.12b).
