Powerful Dehumidifying Capability
Taking advantage of refrigeration technology, the dehumidifier powerfully removes moisture from the air to decrease the humidity level of the room and keep the indoor air dry and comfortable.

Unique Portable Design
The dehumidifier is built to be compact and lightweight. The casters on the bottom of the unit make it easy to move from room to room.

Customized Mode
Allows you to set specific dehumidity percentage and operation mode for most frequently-using rooms in which you are using your dehumidifier (Sleeping Area—55%, Living Area—50% or Basement—45%).

Digital Mirage Display
Easily monitor humidity changes from across the room.

Adjustable Humidistat
Different dehumidification levels can be selected according to different room requirements.

Save Money
This dehumidifier is Energy-Star rated, and could quickly remove moisture from the air without running up your utility bill. Energy Star units not only save energy for the environment, but also cost 30% less to save your money comparing to non-Energy Star units.

Automatic Defrost
When frost builds up on the evaporator coils, the compressor will cycle off and the fan will continue to run until the frost disappears. When the coils are completely defrosted, the compressor or fan (depending on the model) will automatically restart and dehumidification will resume.

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

Option 1: Drain Bucket.

When the drainage bucket is full, the bucket full indicator light will turn on, the operation will stop automatically and the buzzer will beep 3 times to alert the user, that the water need to be emptied from the drainage bucket.

Emptying the Drainage bucket

  1. Lightly press on the sides of the bucket with both hands and pull the bucket out gently.
  2. Drain the collected water.

JHS D025B-25PT Dehumidifier-5


  1. Do not remove the float from the water bucket. The water full sensor will no longer be able to detect the water level correctly without the float and water may leak from the water bucket.
  2. If the drainage bucket is dirty, wash it with cold or lukewarm water. Do not use detergent, scouring pads, chemically treated dust cloths, gasoline, benzene, thinner, or other solvents, as these can scratch and damage the bucket and cause water leakage.
  3. When replacing the drainage bucket, press the bucket firmly into place with both hands.

JHS D025B-25PT Dehumidifier-6

Option 2: Continuous Drainage

Garden Hose Installation Setup
Water can be automatically emptied by attaching a garden hose to the continuous drainage port on the back of the dehumidifier. This will allow the unit to run continuously (depending on the selected humidity level) without having to empty the water bucket. To drain, simply attach a standard garden hose (not included). The thread standard for garden hoses in the US and its territories is known as GHT or “garden hose thread” which has an outer diameter of 1 1/16 inches (1.0625 inches or 27.0 mm) and a pitch of 11.5 TPI.

  • Place dehumidifier on a level surface
  • Unscrew the cap on the back of the unit to access the garden hose nozzle
  • Thread a garden hose (not included) onto the accessible nozzle, lead to a floor drain and cut to length
  • Make sure that there are no kinks or knots in the garden hose (See picture below)
  •  Turn on the unit and press the MODE button until set to CONTINUOUS

Garden Hose Installation Reference Guide

JHS D025B-25PT Dehumidifier-7

Placing the dehumidifier on an uneven surface or improper hose installation may result in water filling up the bucket and cause the unit to shut off. Empty bucket if shut-off occurs, then check dehumidifier location and hose for proper setup. The bucket must be in place and securely seated for the dehumidifier to operate.

Option 3:Pump draining (Pump models only

Internal Pump Mode- The internal pump allows the unit to operate without having to empty the
bucket. To install the Pump Drain Hose Kit, remove the drain cap on the back of the unit. Insert the included gasket into the Drain Adapter, then force the Drain Hose onto the Drain Adapter and turn clockwise onto the garden hose nozzle on the back of the unit as pictured below. (Drain adapter is included in storage compartment on top of water bucket) Once securely installed, lead the Drain Hose to a nearby drain, sink or out of a window up to 16ft height from the base of the unit. Turn on the unit and press the pump button to activate the internal pump.
