Product introduction

Dehumidifier is used for reducing the air moisture of its installation space to a proper level, so as to fit people in the daily life and material storage.

Beautiful in shape, compact in size, convenient in operation, this dehumidifier is widely used in the dehumidification of many sites with high moisture such as scientific researching, medical & health care, commodity storage, underground engineering, so as to prevent the loss caused by moisture, rust, decomposition of apparatus, devices, telecommunications devices, medicines, files etc.

As considering the setting optimum humidity of the climate and environment change, physiological health condition of human, protection condition of indoor furniture and other items varies between 45% to 65%, it is suggested to set the humidity within this range.

Placing

Dehumidifier can protect the room and storage environment from the influence of wet air.

In the event of extra moisture pervade in your room or other spaces, it is same like the cooking smell spread in each room. Therefore, it is required to place the dehumidifier in the center of the room, so as to dehumidify the room evenly and effectively. The warm corridor and platform of stair is the ideal place for placing the machine. If possible, open the door of the house; this is helpful for the air passage.

In the event of special high moisture exist in a certain area of a room, it is suggested to place the machine in this area directly before move it to the center.

For achieving the best effect of dehumidification, shut off the exterior doors and windows during the operation of the device. Do not place the part beside the heater or other heat sources.

When placing the device, ensure to place it in the ground stably on the surface, do not allow block in the air inlet and outlet of the machine.

Disconnect the power and drain the water completely before moving the part.

Store the dehumidifier

When store the machine, the following procedures shall be observed.

  1. Drain the water in the tank thoroughly;
  2. Roll the wire and place it into the water tank;
  3. Clean the filter trap;
  4. Place the device in dry and cool area.

Notes

Keep at least 0.5m safety distance between dehumidifier and any electric appliances and flammable substances.

  2. As shown in the figure, pull the filter handle with your hand up to about 30mm, then pull down the filter by diagonal.

Drainage pipe installation

Image One: Error Connection example

  • The water pipe upward arch position D above position B, the inside of the water pipe is prone to air and accumulation, which leads to a smooth discharge through the Pipe.
    Image Two: Error Connection example

  • The water pipe and the water container contact point D is lower than the continuous drain A, but higher than the water pipe at the lowest point B, the inside of the pipe prone to air and water, leading to a smooth discharge of waters through the Pipe.

  • Do not insert pipe outlet C into water.
    **Image Three: Correct Connection example

**

  • Water through the continuous drainage port A, from high to low through the B and outlet C smooth discharge, can be used to water containers or discharged into the sewer (outlet C is below the continuous drainage port of 10 cm above, do not recommend the addition of the original drainage pipe).
  • Pipes can be bent and not folded on the ground, but cannot be partially arched.

Tips : The machine has no water full prompting function. When the container is used to receive drainage, attention should be paid to water level.
