This document is an owner's manual for a dehumidifier. It provides comprehensive information on safety precautions, operation, maintenance, and troubleshooting for the device.

Function Description:

The dehumidifier is designed to remove excess moisture from the air, helping to prevent issues like mold, mildew, and discomfort caused by high humidity. It can be used in various settings, including homes, basements, and laundry rooms. The device features different operating modes and settings to control humidity levels and can be set to operate on a timer. It also includes an auto-defrost function to prevent frost buildup on the evaporator coils and an auto-restart function that restores previous settings after a power cut. The unit collects water in a removable bucket, which needs to be emptied when full, or it can be set up for continuous drainage. Some models also include a pump feature for automatic water removal.

Important Technical Specifications:

The manual specifies two models: MDDP-30DENT-QA3 and MDDP-50DENT-QA3.

Refrigerant: R290 (0.1kg for MDDP-30DENT-QA3, 0.145kg for MDDP-50DENT-QA3). The manual includes extensive warnings and precautions specifically for R290/R32 refrigerant, emphasizing safe handling, storage, and servicing due to its flammability.
Humidity Range: The display shows set humidity levels from 35% to 85% and actual room humidity levels from 30%RH to 90%RH (with 5% accuracy).
Timer: Auto start/stop time can be set from 0 to 24 hours (0.5-hour increments up to 10 hours, then 1-hour increments up to 24 hours).
Filter Check: The system counts operating time, and the "Clean filter indicator light" flashes after 250 hours of fan motor operation, prompting the user to clean the air filter.
Electrical Information: The unit's electrical specifications are located on the rear panel. It requires a properly grounded three-prong plug for protection against shock hazards. Extension cords should be "Dehumidifier" extension cords only.
Operating Environment: The unit is designed to operate in a working environment between 5°C (41°F) and 32°C (90°F), and between 30%RH and 80%RH.

Usage Features:

Control Panel: The unit features a control panel with various pads and indicators for setting humidity, fan speed (High, Medium, Low), and timer.
Display: An LED display shows the set humidity level, auto start/stop time, and actual room humidity level. It also displays error codes (AS for humidity sensor error, ES for evaporator tube temperature sensor error, P2 for full/misplaced bucket, Eb for removed/misplaced bucket in pump models).
Modes: The manual describes different operating modes, including "CONTINUE PAD" for continuous dehumidification, "TURBO PAD" for maximum moisture removal, and "TIMER PAD" for setting auto start/stop.
Water Collection: Water is collected in a removable bucket. The "Bucket Full Light" illuminates when the bucket needs emptying. The unit automatically shuts off when the bucket is full or removed.
Continuous Drainage: For continuous operation without emptying the bucket, a drain hose can be connected to the continuous drain hose outlet.
Pump Drainage (on some models): Models with a pump feature allow water to be automatically pumped out through a drain hose, even upwards, making it suitable for draining into a sink or other elevated outlet.
Auto Defrost: If frost builds up on the evaporator coils, the compressor cycles off, and the fan continues to run until the frost disappears.
Auto Restart: The unit automatically restarts with previous settings after a power interruption.
Wait 3 minutes: After stopping, the unit cannot be restarted for 3 minutes to protect the compressor.

Maintenance Features:

Cleaning the Grille and Case: The exterior should be cleaned with water and a mild detergent, avoiding bleach or abrasives. Water should not splash directly onto the unit.
Cleaning the Bucket: The bucket should be cleaned every few weeks with water and a mild detergent to prevent mold and mildew.
Cleaning the Air Filter: The air filter should be cleaned every two weeks or when the "Clean filter indicator light" flashes. It can be cleaned by vacuuming or washing with water and mild detergent.
Long-Term Storage: Before storing the unit for a long time, it should be turned off, unplugged, the bucket emptied, the unit cleaned, the power cord wrapped, and the unit covered with a plastic bag and stored in a dry, well-ventilated place.
Professional Servicing: The manual emphasizes that any repairs or maintenance, especially concerning refrigerant-containing components, should be performed by qualified service technicians. It also states that the appliance should be installed in accordance with national wiring regulations.
