Crawlspace Dehumidifier Installations
Installing a Crawlspace Dehumidifier is Easier Than it Sounds!
Have you ever installed a window air conditioner? It’s about that easy – put it in position, run your drain hose and plug it in. That’s it! For your basic installation, follow the 3 steps below. Scroll down further to see some very helpful tips for preparing your crawlspace area and installing the dehumidifier.
| STEP 1 Place dehumidifier on wood or cement block. The reason for the block is to raise the unit up so the water can drain down through a hose. Use Adjustable feet to easily level the dehumidifier. |
 |
| STEP 2 Take the female end of a standard garden hose and screw it onto the drain. Run the hose down and out of your crawlspace or to a pump or drain. You can purchase a condensate pump from our Buy-Now page. |

| STEP 3 Plug it in! If you purchased a condensate pump, plug that into a standard household electrical outlet. |

| Helpful Tips for Installing Your Dri-CrawlSpace® Dehumidifier |
| Check Your Plastic Vapor Barrier Before you begin installation, it’s a good idea to double check your vapor barrier. Make certain the plastic sheeting is secured and that all vents and cracks are tightly sealed to provide effective moisture control.What to Do With Your Crawl Space Vents Until recently, crawlspace vents were designed to allow outside air into the crawlspace to help reduce humidity. This practice began in 1938, but is currently being phased out. Some out dated websites and contractors still repeat the fallacy that adequate venting will reduce crawlspace moisture levels. The reality is that venting will only reduce crawlspace moisture levels when the outside air is dryer than 40% Relative Humidity. Yet, in humid climates and conditions, the outside air will actually contain far more moisture than what you want in your crawlspace.Where to Place Your Dehumidifier When locating a spot in the crawlspace to place your dehumidifier, it is usually best to place the unit in the middle of the crawlspace. This will provide a more centralized airflow that will allow your crawlspace dehumidifier to efficiently remove the most amount of moisture. If you are using multiple units, space them apart to cover maximum area.Raised Blocking for Proper Drainage The next step is to determine how far off of the ground you must place the unit to allow for effective drainage. The unit must be placed higher than the drain to allow the water to flow downward and out of the crawlspace. This is referred to as a gravity drain. Depending on the depth of your crawlspace and grading, you can place the dehumidifier on cinder blocks or you may simply use the half pallet on which the unit was delivered. We do not recommend pouring water into the unit, though some people have been known to disregard our warning and remove the filter so that they may gently pour a cup of water into the styrofoam drain pan to test the effectiveness of their drain hose positioning.Setting Up Your Drainage System There are three ways to drain your crawlspace dehumidifier:
Creating your own drainage system is pretty easy. Make a hole in your vent or outside wall, just big enough for the drain hose.  Be sure it drains far enough away so it cannot re-enter the crawlspace. Depending on the size of your crawlspace and drainage logistics, you may need a condensate pump with additional drain tubing. This is optional on most crawlspace dehumidifiers, and you can find them by clicking Buy-Now in the navigation above.
