How to Build a Kegerator out of a Refrigerator
Creating a great keg refrigerator isn’t all that difficult but it does require some planning. You have to make some important measurements and drill a few holes so it is always better to take things slowly, and understand exactly what you plan on doing before you do it. This will ensure a clean, efficient project. Following the simple process detailed below should ensure hassle free assembly.
Know the Dimensions of Your Equipment:
A standard _ barrel keg has a diameter of 17†and a 24†height (Coors’ kegs have a 17.5†height)
The co2 tank is deceptively large. It has a 19†height and an 8†diameter.
1.) Measure Your Refrigerator
If your refrigerator cannot accommodate the dimensions of the co2 and the keg, you will probably have to use a low profile tap. These taps release the beer at a 90-degree angle, rather than straight up, which saves some valuable space. Another option is using a standard tap with a 90-degree connector piece.
2.) Placing the Faucet
Choosing the proper faucet position is crucial to ensuring a perfect pour. Generally, the best place to install the faucet is the center of the main refrigerator door. It is crucial the faucet be at least 6†away from the freezer door to ensure proper clearance.
3.) Drilling the Shank Hole
It is important that the plastic on the door where the shank is to be fitted is flat.
I. A 7/8†drill bit is required to drill the shank hole.
II. A paddle bit will work for one time use, but drilling through the door will dull the bit. The more expensive forsner bits are generally much better if you plan on using the bit more than one time.
III.Never use a standard 7/8†drill bit. The whole will come out jagged and the shank will not fit. never force the drill bit. You are drilling metal, it takes some time and patience. Let the bit do the work. Once you have drilled clean through the metal door, always realign the bit with the plastic inside to make sure it is aligned with the hole in the metal.
4.) Kegerator Kit Assembly
Begin by screwing the shank through your previously drilled hole. Tighten the shank nut on the refrigerator, so the shank is stable. The large, black washer can be placed on either side of the shank to disperse some of the pressure placed on it during the insertion.
5.) Attch Faucet
Once the shank is securely in place, attach the faucet to the shank with the shank wrench. Using a black neoprene washer, tighten the hex nut on the back of the beer line to the back of the shank.
6.) Connecting Beer Line
Again, using a neoprene washer, tighten the hex nut on the other end of the beer line to the top of your tap. Next, attach to the (don’t know word) beer connection on the top of the tap.
7.) Co2 Line
Find the co2 line. Slide one end of the line over the co2 input nipple on the side of the beer tap. Use an adjustable clamp to secure this connection. Take the other end of the co2 line onto the co2 output nipple located on the regulator. Use another adjustable clamp to secure this connection. Tighten the female hex-nut on the co2 regulator, to the threaded male connection on the co2 tank. Reinforce the connection with a plastic washer. Make sure the connection is tight, as air can escape if the two pieces are not flush together.
I. Find the shutoff valve at the beginning of the co2 line. Make sure the valve is turned toward “OFF.†Open the co2 twist handle, and listen to see if any air is leaking from the connection.
8.) Installing the Drip Tray
Locate a spot that is at least 10â€, and centered below the faucet. Use a level to level the drip tray and mark the points where the two screws will be inserted. The next step is to drill the screws into the marks. Because the screws provided in your kegerator conversion kit are self piercing, you won’t need to use a drill bit. Using a power drill, slowly screw the screws through the metal. Once they have made full entry, retract the screws completely out of the holes. You will be left with two complete holes. Align the wholes of the drip tray to the holes you have just created. Reinsert the screws, attaching to drip tray to the refrigerator.
9.) Supporting the Keg
Because the bottom of each refrigerator is usually different, you may have to make some modifications to ensure your keg rests at a secure and level position. Use a level to check and see if your keg position needs to be adjusted.
If you keg needs to be adjusted, cinder blocks generally make a good leveling support if your compressor compartment is slanted in the back.
Another option is to cut a piece of steel into a support shelf, and suspend your keg below the curved bottom. Make sure to consider that a full keg weighs approximately 140 lbs.
