CAPPUCCINO DISPENSER HELP!

[javagirl]

Hi,

I recently bought my first cappuccino dispenser, but it came without a manual. It is a SINGLE dispenser with TWO separate hoppers. The hopper on the right dispenses the cappuccino mix and water. I am clueless about the hopper on the left side...it spins to dispense, but no water comes out. This machine is a auto/pourover. Please give me an input on what the other hopper is might be for. Thanks

MODEL: KARMA 453

I can't find anything on the internet about it.
