Review for the Colaze Model PD15R-01AE 4500 sq.ft. - 50 pint Dehumidifier:**Unboxing and Setup Review:**The Colaze PD15R-01AE Dehumidifier arrives in a compact, well-protected packaging that includes sturdy styrofoam cushioning. The unit itself exhibits a substantial weight for its size, reflecting its solid construction. Out of the box, the dehumidifier comes fully assembled, featuring four wheels on its base for convenient mobility. After removing the protective packing materials and ensuring the proper placement of the water tank, it can be swiftly plugged in and made ready for use.Inside the box, you'll find:- Dehumidifier unit with a fixed power cable- Drainage tube- User Manual- Installation instructions for the included drainage tube- Warranty Registration card**Setup:**Setting up the Colaze PD15R-01AE is remarkably straightforward, with just a few considerations:1. Remove all packing materials, including the protective wrap and the water reservoir.2. The water reservoir comes equipped with a handle for easy carrying; please avoid attempting to remove the handle or the top of the water tank to prevent any impact on the automatic water stopper function (a built-in foam floater).3. Locate the drainage tube in the box and follow the provided instructions if you prefer direct drainage over using the water tank.4. Check the water tank's foam floater by turning the tank upside down to ensure it moves freely within the tank.5. Place the dehumidifier on a level surface to prevent water spillage (especially if not using the drainage tube).6. Plug in the power cable to an outlet.7. On top of the unit, you'll find four touch-sensitive buttons (Humidity Setting, Timer, Speed, Power). Touch the power button to activate the unit, and it will display the current room humidity after a brief moment. This display will continually update as the unit operates.8. Unless you need to adjust specific settings, your dehumidifier is now operational, and you should start seeing collected water in the reservoir shortly.**Dehumidifier Features:**- Dehumidification Function: The unit offers three modes - Auto, Clothes Dry, and Fan - providing flexibility in how you want it to operate. The "Auto" mode adjusts dehumidification and fan speed based on your chosen humidity setting. "Clothes Dry" runs the dehumidifier continuously with a high-speed fan, while "Fan" mode only operates the fan, with the compressor turned off.- Fan Speed: You can easily switch between low and high fan speeds. The high-speed setting is particularly effective for quick dehumidification, and it operates quietly.- Timer: Set the timer to control how long the unit runs. A setting of "0" means continuous operation, and it will shut off if the water tank fills before the timer completes.- Humidity Control: Adjust the humidity setting in 10% increments between 30% and 80%, or choose continuous (CO) mode. The digital display cycles through the selected humidity level.- Auto-Shutoff: The dehumidifier will automatically power off and indicate when the ~1.5-gallon water reservoir is full. Regularly inspect the foam floater after emptying the tank to ensure proper functioning.- Auto-Defrost: The defrosting function activates when frost build-up is possible based on environmental conditions. The unit will shut off for a defrost cycle before resuming operation.- Child Lock: A child lock feature prevents settings changes when enabled.**Testing the Unit:**Setting up the unit was a breeze, taking only a couple of minutes. The initial humidity reading in the room was around 53%. Adjusting the humidity setting to 60% caused the unit to stop immediately, while setting it to 50% resumed dehumidification.Running the unit overnight, it stopped by morning when the room humidity reached 43%. The water tank was about half full, so I emptied it and restarted the dehumidifier. Over the course of several days, I gradually lowered the humidity setting to 30%, achieving a room humidity of approximately 39%. Even after continuous operation for a few more days, the humidity remained at 39%, suggesting this was the optimal level for the testing area. Considering it was an open hallway, this performance was impressive.**Review Summary:**I am exceptionally pleased with the performance and capacity of the Colaze PD15R-01AE Dehumidifier. With its 50-pint capacity, it is well-suited for large open spaces. The water tank's ~1.6-gallon capacity allows for extended operation between emptying. Operating the unit is straightforward, and the noise level, especially the fan, is quite tolerable. In fact, I often forget it's in the hallway until it powers off due to a full water reservoir.Be cautious when handling the full water reservoir, as it can be heavy. Always use both hands to ensure stability and prevent spills. I confidently recommend the Colaze Dehumidifier to those seeking effective dehumidification for spacious areas. Once your desired humidity level is achieved, you can easily adjust settings for continuous operation.
