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.
After examining the features, design, and positive reviews; I bought the Friedrich D50 – and thought to share the installation process, along with my experience and thoughts along the way.
Why have a dehumidifier?
A garage, basement, or any other space experiencing excessive humidity can wreak havoc on tools, furniture, clothing, etc., and create damaging mildew in your home when not controlled.
Why choose a Friedrich dehumidifier?
There are many top rated dehumidifiers to choose from, but I wanted to try a brand with a focused product line.
Friedrich makes in room air conditioners and 3 models of portable dehumidifiers. Nothing else!
What size dehumidifier should I buy?
Dehumidifier capacity is measured in pints per 24 hours and determined by two factors.
- The size of the room.
- The conditions / amount of humidity in the room.
Friedrich’s 3 dehumidifier models (D25, D50, D70) handle small to very large spaces.
|Room Conditions||Small to
100 – 1,000 sq. ft.
1,000 – 2,000 sq. ft.

How to install a Friedrich dehumidifier with continuous drain
After unpacking the Friedrich dehumidifier; I found the D50 dehumidifier fully assembled, minus the optional drainage parts.
- The D25BNP includes casters, but they need installing, whereas the D50BP and D70BP have the casters pre-installed.
- Inluded in all 3 models – is a corrugated continuous drain hose (hose in the middle of the drain bucket).
- Models D50BP and D70BP include another smaller vinyl hose (hose in the left side of the drain bucket) for the built-in drain pump feature.
Note: The tape covered part in the right side of the drain bucket – is the float – which 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 a gravity fed floor drain? Maybe you need to route a hose upwards into a sink?
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 does not fill.
- 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 spare part storage 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 – Choosing the D50BP or D70BP humidifier adds 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 total distance of 15 feet.
However, this type of continous drain allows the drain bucket to fill. Once the float activates – the pump turns on to 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: To remove the hose and key assembly, push the ribbed portion of the button to unlock.
Plug In and Power Up
After the drainage is decided and installed, the remainder of the setup is simple.
Plug the dehumidifier into a 115VAC outlet and push the power button.
Top Panel Control Features
The easy to navigate control panel includes large LCD readouts for room temperature and humidity.
The only missing feature is a notification light when the filter is dirty.
If you have further questions, concerns, or pre-purchase product queries, the dehumidifier Installation and Operation Manual in the Brochures tab can be helpful.
Easy Access Filter
The filter needs periodic maintenance and is conveniently located in front of the control panel.
Lift up on the handle for filter removal and slide back in after inspection. No need to remove other parts or dig for an internal filter.
What I didn’t find in the manual
Once the setup and activation was complete, there were a few concerns, and the answers I needed weren’t found in the manual, so I called customer service.
Q) 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.
A) This is normal.
Q) The humidistat seems very inaccurate (5% variance) on turning the dehumidifier off / on at setpoint.
A) 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.
The installation was easy, the features are sufficient, and the overall design was well thought out.
If there are any questions about long-term dependability, please leave a comment for a response.
