If the said methods still fail to eliminate the above problems, please directly contact the manufacturer or agents. DO NOT disassemble the dehumidifier, contact Sealey for repairs. It’s normal to hear the sound of the circulation of refrigerant when the dehumidifier runs. It’s normal for the air vent to blow warm air.
INFORMATION FOR THE USER: As a precision part, the humidity sensor may be damaged when used in environment filled with strong corrosive gas and heavy dust. As the dehumidifier is non-resistant against explosion, it’s forbidden to be used in environment of special requirements such as that filled with combustible/explosive gas, dust, chemicals or biological products. Damage caused to the dehumidifier by use in said environment will void the warranty. As water may be discharged from the machine after a certain amount of use, attention shall be paid to managing this water. To minimize faults and maximize the lifetime, press the buttons gently. The deviation between the humidity shown on the sensor and the actual humidity is normal, due to impact by the location, environment and temperature. Since the cooled air is dried by the condenser before being discharged during operation of the dehumidifier, it’s normal for the air discharged to be hotter than the environment. Since the dehumidifying effect is associated with the temperature and humidity of the environment, the higher the temperature and humidity of the environment, normally the greater the dehumidifying effect; while the lower the temperature and humidity of the environment, typically the lower the dehumidifying effect.
