Set an Air Clean Filter

Notes:

The time life of the ionic and carbon filter is based on the environmental air, normally it replaces after 1 year. If it is dirty, clean up dust or debris with a brush and dry it in the sunshine.

Clean and Maintenance

Warning:

• Before cleaning, turn off the dehumidifier and disconnect power. Otherwise, it may lead to electric shock.
• Do not wash the dehumidifier with water, or it may lead to electric shock.
• Do not use volatile liquids (such as thinner or gasoline) to clean the dehumidifier. Otherwise, it will damage the unit's appearance.

1. Grille and Case

To clean the case:

When there is dust on the case, use a soft towel to dust it off. When the case is very dirty (greasy), use mild detergent to clean it. To clean the grille: Use a dust catcher or brush.

2. Water Bucket

Every few weeks, clean the bucket to prevent growth of mold, mildew, and bacteria. Use a soft brush to clean the bucket and then rinse it.

Warning:

Units Condition: Temperature and Humidity Sensor is damaged.

Defrost Procedure

Please note if the ROOM temperature is less than 24°C, the unit will start defrost function!

• ≥24°C: no defrost
• 18-23°C: 2 hours dehumidify then 5 minutes defrost, cycle.
• 12-18°C: 25 minutes dehumidify then 5 minutes defrost, cycle.
• 5-12°C: 8 minutes dehumidify then 3 minutes defrost, cycle.
• ≤5°C: unit protection, compressor off, fan off. All operation mode cannot be activated except air circulation mode.

Problem: Dehumidifier does not dry air as intended. / Bad dehumidifying performance.

Possible Causes:

• Check whether there is any obstacle around the unit.
• Air filter is dusty and blocked.
