How to turn Spa bubbles on through jets?

[bradtm]

I don't have my new pool/spa orientation for another 4 days, and have been able to figure out mostly everything about my equipment except how to turn the bubbles on in the spa. There is a pipe semi-close to the spa they told me that pulls in air into the spa, yet, I can't figure out how to turn it on. I messed with a valve, and don't see a blower anywhere. Anyone have any idea?

The left side is the return and the right side is suction.

Can you post a pic of the spa? You may have little air control valves that allow more air through venturi chambers. Sometimes they are little knobs around the rim of the spa. My jet nozzles turn with a wrench to adjust airflow (i.e. bubbles).
