Major VersionM

  1. Before you start to take the tap apart above the counter, be sure to disconnect your steam tap from the steam module via the quick connect! Use caution as some steam or hot water could still be in the steam tap line. Next, loosen the three set screws and remove the cap from the steam tap tower with the 3mm hex wrench (could also be small standard screwdriver). Remove the wand acorn nut with a 22mm open end wrench (10" adjustable will work here as well).  The wand is under spring pressure, so be careful when removing the wand and be sure to save all the small parts for reassembly.

  2. With the wand removed, pull the valve assembly up and out of the tower enough to access the shoulder bolt.  Remove the shoulder bolt that holds the handle in place with a 1/8" hex wrench.  Pull the handle out of the bracket.  Clean the metal surface of the handle if you have a build up of old lube and steel shavings. Now that the handle is out, you are now ready to remove the old stainless drive shaft.  It should just pull straight up and out of the valve body.   You can feel free to recycle the old stainless steel drive shaft. Use a small amount of food grade silicone grease or moly cote 111 on the O-rings on the new Peek drive shaft.  Place the new drive shaft into the valve body using a twist and push motion.

  3. Install the handle back into the bracket, and use the 1/8" hex wrench to tighten the shoulder bolt. Set the valve body back down into the steam tower and get your wand parts ready to install.  Do not forget to put the shims in the wand fitting before the spring and brass cup! Use a small amount of food grade silicone grease on the back of the brass cup and spring to hold the parts in place as you install the wand assembly.

    • Apply a small amount (grain of rice size) of Permabond (or food safe liquid thread sealant) to the threads of the wand fitting. Next, install the wand on to the valve body. You can use a wrench to block the valve body in place if you are having trouble keeping the valve in the tower while installing the wand against the spring pressure.

    • Do not use a thread locker on the wand acorn nut!

  4. Place the cap back on the steam tower. You can now plug your tap back into the steam modules CPC quick connect fitting.  This is a good time to listen/look for any sign of a leak!
