Friedrich built their name in the room air conditioner market, but their line of portable room dehumidifiers caught my attention while looking for a new dehumidifier to replace our now defunct Kenmore model. The design and overall features looked perfect for our wants and needs, so time to unwrap this thing and do a complete install, including continuous drainage.
A garage, basement, or any other place experiencing high humidity can wreak havoc on tools, cabinets of all materials types, clothing, etc., and create damaging mildew on your home.
Our house, for example, averages 10% higher humidity when no dehumidifier is active. That’s a substantial increase during the hot and humid months. We want to keep the amount of humidity in check so we don’t cause unnecessary damage that can cost into the thousands of dollars to replace and repair.
Dehumidifier capacity is usually measured in pints per 24 hours and is determined by two factors: the size of the space that needs to be dehumidified, and the conditions that exist in that space before dehumidification.
Why Choose a Friedrich Dehumidifier?
There are a lot of brands making dehumidifiers as part of their diverse product lines. This time I wanted to try a brand that has a more focused product line. Friedrich primarily makes in room air conditioners and 3 models of portable dehumidifiers. Nothing else. We’ll see if their limited prioritization equates to a better product.
Top Panel Control Features
The dehumidifier functions are very accommodating and easy to understand. The only feature missing and I would like to see added is a notification light when the filter is dirty.
Easy Access Filter
The filter with handle is conveniently placed in front of the control panel and accessible from the top. Lift up for removal…slide in for insertion. No need to remove other parts or dig for the filter internally.
Once the dehumidifier is removed from the box; the dehumidifier is mainly assembled; you’ll want to remove the drain bucket to access the included accessories.
- The D25BNP model will have casters that need to be installed, whereas the D50BP and D70BP will have the casters already attached.
- A corrugated continuous drain hose (middle hose in image) is included in all 3 dehumidifier models.
- Models D50BP and D70BP include another smaller clear vinyl hose( left hose in image) for the built-in drain pump feature.
Note: Far right part in drain bucket (blue tape covered) is the float that activates the built-in drain pump or shuts the dehumidifier off when the bucket is full.
Two Drain Options
Who wants to keep emptying a bucket of water daily! Many dehumidifiers have a continuous drain feature, but what if you don’t have the luxury of draining downwards into a floor drain? Maybe you need to route a hose upwards into a sink?
Larger capacity models D50BP and D70BP have built-in drain pumps that can pump condensation vertically or horizontally up to a combined distance of 15 feet.
Option 1 – All 3 models (D25BNP, D50BP, and D70BP) have the continuous drain port. This works by gravity alone, so the hose needs to route downward and into a drain. The drain bucket will not be filled.
- Remove the drain cap and rubber plug. Store the black plug in a safe place in case you need to reinstall it again. The drain bucket is a good option since it won’t be filling with water anyways.
- Insert the supplied rubber o-ring into the flange end of the corrugated hose. Slide the cap over the other end.
- Tighten the cap back onto the threaded fitting.
Make sure the drain hose is flowing downward. A sump pump basin or floor drain makes displacing water maintenance free.
Option 2 – Choose either the D50BP or D70BP models and the humidifier will include another drain port that’s connected to a built-in pump. Now you have the ability to pump condensation vertically or horizontally up to a combined distance of 15 feet.
This drainage option, however, does allow the drain bucket to fill, then once the float is activated, the pump will turn on and empty the drain bucket.
- Locate the built-in pump drain port.
- Locate the supplied drain hose with pre-attached locking key.
- Push the hose and key assembly into the port until you hear a “click” sound.
Note: The hose and key assembly are easily removed by push the ribbed portion of the button to unlock.
Plug In. Power Up. Remove Humidity.
Like most portable dehumidifiers, the installation is fairly straightforward once you sort out your drainage needs. The settings control panel is simple to understand. Plug the dehumidifier in a 115VAC outlet, push the power button, and adjust your settings.
If you have any additional questions, concerns, or pre-purchase product queries, the Dehumidifier Installation and Operation Manual in the Brochures tab can be helpful.
Information not in the Manual
Once the setup was complete, there were a few concerns I had about how the Friedrich D50BP dehumidifier was operating, and the answers I needed weren’t found in the manual, so I called customer service.
- Removal and reinsertion of the drain bucket has around a 2.5 -3 minute lag before the dehumidifier auto restarts if power was never turned off. Friedrich confirmed that this is normal.
- Humidistat seemed very inaccurate (5% variance) on turning the dehumidifier off / on at setpoint. Friedrich advises to set the humidity control at the lowest setting of 30% for a day or two. The humidistat will adjust itself to the environment, then setpoint should be more accurate.
We’ll continue to check back and log long term results of our Friedrich D50BP dehumidifier.
- June, 2015 – Initial installation
- May, 2016 – A long winter but finally enough humidity in the atmosphere to justify the need for a dehumidifier in the basement. The unit was plugged back in and turned on with zero problems. Note: Now’s a good time to check the filter and inspect the drainage, if connected.
