    co2 tank


    most common sizes are 5, 10 & 20lb tanks. consider your consumption rate and where you are going to store the tank. more tips(1)

    1. - you need to also consider how you are going to run your co2 hose adapter from the tank to the carbonator. also consider the tank material(1), valve type(2) and local availability for refilling(3). more safety tips(4)

      1. typically aluminum or steel. check for DOT approved.
      2. look for a cga320 valve
      3. check out local beverage centers, home brew supply stores, i went to airgas
      4. store in a cool, dry place. consult a specialist for advice. handle with care.

    when attaching or removing hoses, connectors, anything really

    the first thing you need to do is fully close the main co2 tank valve. then do all of your work and ensure everything is snug back up tight. then when you are all done then open the co2 tank valve, test for any loose fittings and then enjoy.

    don't use excessive force when using the carbsocket

    please remember, the CarbSocket is plastic it will eventually break but i have tested it many, many times and can tighten the adapter to what i approximate a solid 'snug, hand tight' fit with the ratchet with no damage to the CarbSocket. this is version 11 of the CarbSocket and the first 10 didn't pass the tests. cranking down on the fitting with a ratchet may also damage the carbonator and we don't want that either. there should be a gasket in the tr21-4 so once i feel it getting snug i just give it a little bit more torque and stop.

    attach the connector to the tank first

    see below for additional installation instructions and tips

  • assemble the tools


    ratchet extension & carbsocket


    connect the ratchet to the socket extension and then attach the carbsocket to the extension.


    secure the carbsocket to the extension

    the carbsocket is designed to secure to the extension just like any other socket. there is a groove inside the pocket to allow the ball bearing on the extension to secure itself inside the carbsocket.


    choose the proper extension

    the absolute minimum extension length is a 10" but longer ones will work better. you can also daisy-chain multiple extensions together to achieve the required length.

  • insert tr21-4 adapter into the carbsocket


    ratchet extension & carbsocket


    with the hose attached to the tr21-4 simply feed the hose through the CarbSocket with the other end of the hose towards the ratchet and the threads of the tr21-4 towards the top of the CarbSocket


    align the tr21-4 connector with the CarbSocket's opening then


    proper insertion of tr21-4 adapter into the CarbSocket

    the CarbSocket allows you to connect and disconnect the hose adapter's tr21-4 connector to the carbonator while the hose remains attached.(1)

    1. this is a key design feature of the CarbSocket. a normal socket could attach to the carbonator's inner connector, but the hose couldn't be attached afterward. the CarbSocket's slot opening allows the hose to be inserted and removed while still connected to the tr21-4 connector.

    keep the tr21-4 connector's threads exposed

    the CarbSocket is designed to prevent the tr21-4 connector from sliding through, ensuring the threads remain exposed. it also provides a pocket for the hose to flex within the extension.


  • prep the carbonator and tooling


    ratchet extension & carbsocket


    lay your carbonator on a towel on the counter top on its side with the bottom opening facing towards you.


    use a flashlight in one hand (or a back ceiling light) and the ratchet and a slight tug on the hose in the other hand.


    get some extra hands if you need it

    there are plenty of moving parts here. after dozens of tests the process has almost become second nature to me but early on it was a group effort.


  • connect the tr21-4 connector to the carbonator


    ratchet extension & carbsocket


    guide the tr21-4 adapter to the mouth of the female adapter way up in the tower of the carbonator until you feel it align the opening. to ensure a secure connection, align the two connectors carefully. make sure the threads are properly engaged before tightening.


    gently rotate the ratchet until you feel it get snug and then rotate just a tiny bit more to properly secure the tr21-4 connector to the carbonator connector.


    remember lefty-loosie, righty-tighty

    adjust the socket ratchet so it applies clockwise (tighten) or counter-clockwise (loosen) force depending on your needs. check it before you start to


    let the hose spin and coil as you connect or disconnect

    these adapter hoses sure do like to coil up while you are threading connectors. you can fix that later. focus on getting the connectors properly aligned and secured.


  • additional installation instructions & tips


    as you probably know, the other side of the hose has a (usually) bronze fitting that attaches to the tank.


    co2 hose


    attach the connector to the tank first

    the hose will coil up a bunch as you tighten as it may not 'slip' or rotate freely as you tighten the connector. other hose adapters may. ensure that the release valve is closed and that all of the threads/fittings on that side of the hose are "snug tight" using a crescent wrench.


    is your hose coiling?

    if you run into hose coiling issues you can:

    • reverse pre-coil the hose in the opposite direction before attaching

    • spin the co2 tank itself to uncoil the hose. it took me a bit but I eventually got it down.

    this is the exact issue that inspired the creation of the CarbLift by alloatech studios. the CarbLift elevates your carbonator and gives it a secure surface to rest all while providing ample space for the CO2 hose to connect through the access hole without bending or kinking the hose. this not only ensures a secure and efficient connection but also enhances the overall stability and aesthetics of your setup. say goodbye to workaround stands and hello to a sleek, functional carbonation station with CarbLift.

    😬 drill through your counter top 😬

    use a 1" diamond hole saw since the drink station(1) counter top was some sort of non-wood, resin material so it was easy to drill through it.(2)

    1. drink station
    2. counter top hole

    customer idea - wooden serving tray

    one of my customers bought a little raised serving tray and placed the whole unit on top. if you buy a rectangle one with a flush top you can turn it upside down and easily drill access holes through the back and now top to feed the connector and hose through. if it is big enough you can store flavorings, bottle and accessories on it to make it a proper station.(1)

    1. something like this one might work just fine wooden serving tray

    last resort

    you could consider drilling a hole in the back of the aarke pro which I would have done but didn't have to. actually, i may not have drilled a hole in it as the carbonator has a inner wall and who knows what is inside there. could be important. beware.
