Nozzle won't stay on steam tube

All your delivery tubes are blocked with congealed sour milk. These machines need cleaning daily with Enzyme milk cleaner like Rinza, but they don't tell you this stuff when you buy them. I spent the last 9 years of my career with high volume coffee machines (1,000 cups a day) and ours were cleaned three times a day. In a previous position where they were actually done once a day, the tubes sometimes had to be removed and cleaned manually. The milk in the tubes was disgusting and stuck to the walls of the plastic tube like glue! They also don't tell you that these machines need dealer service every 6 to 12 months.

Clean an iron:

1. Unplug the iron and make sure it is cool before cleaning.
2. Use a toothpick or pipe cleaner to remove buildup in the steam vents, making sure the debris doesn't fall into the vents.
3. Use a fine sewing needle to carefully clean the spray nozzle of mineral deposits.
4. To flush sediment from a steam iron, pour 1/2 cup water and 1/2 cup vinegar into the water tank. Place the iron on a rack over a broiling pan and set the iron to steam until the tank runs dry. Repeat if necessary. Or follow the instructions for using a commercial iron cleaner.

Service the steam and spray mechanism:

1. Unplug the iron.
2. Use a fine sewing needle to unclog the steam valve assembly. Also, check the valve spring and replace it if it is broken or has lost tension.
3. If the spray pump is accessible, remove it and check for leaks by placing the spray tube in wat

If you are looking for a manual, you can contact Jura Capresso directly. If you are just looking for directions for making a cappuccino in general:
Brew the espresso.
Use the steam wand/frothing element and a pre-chilled frothing pitcher (the pre-chilling is optional, but it is considered good form) to steam about 1/4 to 1/2 cup of milk.
A true cappuccino does not involve pouring all of the milk directly into the espresso - you would use a spoon to take about two spoonfuls of the top of the steamed milk and place it on top of the espresso.
You can sprinkle cinnamon, use a cinammon stirring stick, or pour cinnamon cappuccino flavoring on top of the cappuccino for good form (but this part is optional).

Enjoy!

I have a PDF of the user manual if you want me to e-mail it to you. In the meantime, here is my Wiki Manual (BTW, pagan, the machine does make hot espresso or cappucino, but it doesn't froth per se like a regular espresso machine - it just heats the milk internally and dumps it into the espresso):

General Directions for Making Iced Cappuccinos
- Place carafe on top of drip/tray grate with handle touching right front of ICAPP – the ice fill lines should be visible when looking at front of unit
- Turn “milk knob” to OPEN position, and open lid of ICAPP
- Remove milk container, espresso collector, espresso spinner cup and cover
- Put espresso collector back in place with two plastic teeth facing front of machine
- There is a stepped fill line inside water reservoir that measures off 1,2, and 4 cups
- Fill water reservoir with either 1,2 or 4 fill line cups – do not overfill to avoid damaging the electronics
- Add espresso grounds to espresso spinner cup
- Line up teeth of spinner cup cover with spinner cup so that the cover locks into place
- Fill milk reservoir with 3 oz of milk per cup of iced cappuccino that you plan to make – there is a fill line that measures off 2 cups or 4 cups
- Fill carafe with either 2 cups worth of ice or 4 cups, depending on how much iced cappuccino you plan to make
- Press down on lid and turn milk knob to HEAT postion
- Turn ICAPP on using the ON/OFF button – it will begin to heat – takes about 5-6 minutes (HEAT light will stay on during this process – doesn’t make noise or steam for several minutes)
- When READY light turns green, turn the milk knob to the DISPENSE MILK position – your espresso and milk will start dispensing
- Unit turns itself off automatically when ready – takes several minutes

I can answer just about any question you have on the unit - I wasn't able to find the manual online, but I would be more than happy to scan and e-mail you my copy of the original manual. In the meantime, here is my basic Wiki Manual:
Since I am not well-versed in the copyright laws regarding reprinting copies of standard user’s manuals online, I am writing this Wiki Manual for the ICAPP-4. My unit is 12 years old (in 2009) and continues to run strong through two different owners.

I've only had it fly off once.  I think I didn't put it all the way on.  Also make sure you clean the nozzle every time you use the steamer.  Milk will clog the nozzle otherwise.  My maker is right beside the sink and I rinse the nozzle immediately after steaming milk.  I also run it through the dishwasher at least weekly.  (This isn't a substitute for immediate clearing of the nozzle.)   A clogged nozzle will always blow off the end.
