The Whynter RPD-551EWP is a portable dehumidifier designed to efficiently remove moisture from the air in indoor residential spaces up to 4000 sq ft. It operates by drawing moisture-laden air across dehumidifying coils, condensing the moisture, and then releasing dry, warm air back into the room. The collected moisture is stored in an internal water bucket or can be continuously drained using a hose. This appliance is Energy Star rated, indicating its energy-efficient operation.
Function Description
The primary function of the Whynter RPD-551EWP is dehumidification. It is capable of removing a significant amount of moisture from the air daily, contributing to a more comfortable and healthier indoor environment. The unit is designed to operate effectively within a temperature range of 41°F (5°C) to 96°F (35°C). A key feature is its "Compressor" circuit, which includes an automatic 3-minute time-delayed start. This delay prevents overheating of the compressor and potential circuit breaker tripping, especially if the appliance is turned off and on quickly. The dehumidifier will not operate if the water bucket is not correctly fitted, ensuring safe use.
Usage Features
The Whynter RPD-551EWP offers several user-friendly features for convenient operation:
- Control Panel: The unit is equipped with an intuitive control panel that allows users to manage various settings.
- Current Temp/Timer/Humidity Display: This display shows the current temperature on the left side and the actual humidity on the right. When the timer function is active, the left LED display changes, and the user-desired humidity level can be manually set and viewed on the right LED display.
- Humidity Control: Users can set the desired humidity level within a range of 30% to 90% Relative Humidity (RH) in 5% increments using the UP or DOWN arrows.
- Auto Shut Off: The dehumidifying function automatically shuts off once the selected humidity level is reached, conserving energy.
- Energy Saver: To enhance energy efficiency, the fan continues to run even after the desired RH% is reached. This helps avoid high start-up amperage.
- Auto-Restart: In the event of a power outage, the appliance will restart at its previously set function mode and settings once power is restored. This feature does not apply to the Timer Function.
- Timer Function: The unit includes a timer for both auto-stop and auto-start functions. When the appliance is ON, pressing the Timer button activates the auto-stop function. Users can set the desired time delay OFF hours (1 to 24 hours) using the UP and DOWN buttons. The appliance will switch off after the set time. To cancel, set the time to "00" or turn off the appliance. Similarly, when the appliance is OFF, pressing the Timer button activates the auto-start function, allowing users to set a time delay ON hours (1 to 24 hours) after which the appliance will turn on.
- °C/°F Selector: The temperature display can be switched between Celsius and Fahrenheit.
- Bucket Full Lamp: A red indicator light illuminates when the water tank is full, signaling that the dehumidifier will stop operating until the bucket is emptied and reinserted.
- Defrost Lamp: A yellow light indicates when the unit enters defrosting mode, which occurs at low ambient temperatures (below 53°F or 12°C) to prevent frost buildup on the evaporator coils. During defrost, the compressor cycles off, and the fan continues to run to evaporate the frost.
- Continuous Drainage: The dehumidifier offers two methods for continuous drainage:
- Water Pump Method: This unit comes with a 16.5 ft. water pump hose. Once connected to the water pump powered outlet, the internal water pump activates, pushing water up or over a longer distance. This allows for maintenance-free operation without needing to empty the water bucket manually. The pump will not activate if the water bucket is full.
- Gravity Method: A 3 ft. drain hose is also provided for gravity drainage. For this method, the dehumidifier must be placed on a level surface at least 12 inches above the ground, such as on a sturdy table or shelf. The hose must be placed horizontally below the drainage hole, avoiding uneven ground or kinks.
Maintenance Features
Regular maintenance is crucial for the optimal performance and longevity of the Whynter RPD-551EWP:
- Cleaning the Air Grille and Main Unit: The main unit can be cleaned with a damp cloth and mild detergent. Bleach, chemicals, or abrasives should be avoided. Direct water splashing on the unit is not recommended. A vacuum attachment or brush can be used to clean the air intake and outlet grilles.
- Cleaning the Water Bucket: The water bucket should be cleaned every two weeks to prevent mold, mildew, and bacteria growth. It can be filled with warm water and mild detergent, then thoroughly dried before reinserting. The bucket should not be cleaned in a dishwasher.
- Cleaning the Air Filter: The removable and washable air filter should be cleaned at least once every two weeks to ensure proper air filtration and efficient operation. To clean, remove the bucket, pull the filter downwards, and use a vacuum cleaner or tap the filter to remove loose dust and dirt. The filter can then be rinsed under warm or cold running water (not hotter than 100°F), thoroughly dried, and reinstalled.
- End of Season Storage: Before storing the unit at the end of a season, it is recommended to wait 24 hours after turning it off to allow excess moisture to drain. The main unit, water bucket, and air filter should be cleaned as detailed above. The unit should then be covered with its original plastic bag or a suitable dust cover and stored upright in a dry, well-ventilated area.
The Whynter RPD-551EWP is designed to be a reliable and effective solution for managing indoor humidity, contributing to improved air quality and comfort while being mindful of energy consumption.
