First of all, of course, unplug The SUB and remove any SUB Kegs and then:

1. Deep clean The SUB

Clean the interior of The SUB chamber thoroughly and make sure you dry any moisture completely. Be sure to also clean inside the mechanism of the tap handle, using warm water to remove possible beer residues (it is possible to use a cotton swab for smaller, fiddly parts). Lastly, clean the air vents both on the sides and under The SUB by carefully removing any dust that may have accumulated.

2. Storing The SUB

Leave the tap mechanism off and wind up the cable to avoid tangling or bending. Only once The SUB is perfectly cleaned and dried, store it in a cool dry place. Ideally in a place with room temperature which doesn't exceed 25 degrees. Never store The SUB outside under the direct sun or anywhere where it could possibly enter in contact with water. Try to avoid storing the SUB in a room with a very high percentage of humidity.

3. Bring The SUB back to life

When you're ready to get your pro pint pulling machine back in action, there are just a couple of things to bear in mind. When turning The SUB back on, after any length of time, check if any dust has deposited on the vents. If this is the case, then remove it with a dry cloth. Make sure you leave The SUB plugged in for at least half a day before inserting a keg. This will give your machine time to fire up cool to the desired temperature.

Simple! You're ready to start pulling perfect pints again!

Installation and maintenance

I have plugged in The SUB and connected a keg. When I can start tapping?  

Once the beer is chilled to the right temperature, the light on the front of The SUB will turn green. The beer is at the optimum temperature and can now be tapped.

Do I have to wait until it turns green?

Pouring before the keg is fully chilled will produce a lot of foam. It won't harm you, but we don't recommend it. For the optimum experience, it is best to wait.

Should the device remain switched on all the time during use?

When there is beer in the keg it should remain on to keep the beer chilled and fresh for 15 days. This will also keep the correct pressure. If the chamber is empty, you can turn the appliance off.

How long does it take to cool a SUB Keg?

We advise pre-chilling your kegs for 6-8 hours in the fridge before use. If appliance and keg are at room temperature it will take around 10 hours to cool.

How do I load a SUB Keg into The SUB?

Remove the top of the keg sleeve along the dotted line. Then remove the cap and take the tube out. Push the tube into the opening until you hear a "click" sound, this is very important. Now slide the SUB Keg into the cooling chamber, make sure it goes right to the end. Then open the tap cover and guide the tube into place. Snap the beer valve in its position in the tap head. Close the tap cover, close and lock The SUB door and you're done.

Where should The SUB be placed?

The small footprint means it will fit on any countertop. Place it on a flat, clean and dry surface with access to main supply. We also advise customers to leave enough space around the machine, to make sure that it can cool.

My SUB light is red

This usually means the kegs are cooling. If you pre-chill your kegs before use, this will be a lot quicker. If the appliance and keg are at room temperature it can take 10 hours to cool.

If the red light persists, try pouring a little beer. This might trigger it to turn green.

When I try to tap a beer, I only get foam. How did that happen?

There can be several causes of this:

  • Sometimes the first glass you tap can largely be foam
  • Sometimes the tube will fill with gas if you haven't drawn the beer through the tube yet
  • If the temperature of the beer is too warm or too cold
  • The beer is not tapped correctly: To tap, you must open the tap handle quickly and pull it down fully. Tilt the clean glass at a 45° degree angle, keeping the glass close to the tap. 

Is it normal to get a glass full of foam with the first tap?

Yes, the first glass from a new keg will primarily be foam, so don't panic. However, if the amount of foam is the same in the next, it is possible the keg is not cold enough.

Can I adjust the temperature of the drink?

No, the appliance will chill the beer to 2° C.  

Krups SUB is making noise, is this ok?

Indeed, it does make a humming sound when it is cooling. It can  also make a similar noise when it is pressurising and when you are draughting a beer.

What do I do if the light won't turn on?

Once in the machine, a SUB Keg takes 10 to 16 hours (depending on starting temperature). When your beer is chilled to the right temperature, then the light on the front will turn green. To expediate the process, you can pre chill your kegs in the fridge.

The temperature of the SUB Keg depends on the temperature in the fridge and how long it has been in the machine. If the temperature of the room is above 30 °C and the SUB Keg has not been pre-chilled, it can happen that the light does not turn green. The temperature of the beer in this case is within 2 – 6 °C and still cooling. Be patient, it can take a bit of time. 

What do I do if the machine is not working?

After following the instructions in the manual and reading our steps, ensure that your electrical socket is working by testing it with another appliance in. If it still does not work, do not try to dismantle or repair the appliance yourself, instead, contact customer support.
