For a 1C charge rate, which is generally safe for all lipos, set the charger to 2.2 Amps.

A 1C charge rate is the capacity number expressed as a current value. For a 2200 mAh battery, the 1C charge rate is 2200 mA, which equals 2.2A. So set the charger to either 2200 mA or 2.2A (they are the same thing, but some chargers may display mA while others display A). A full charge will take a bit more than one hour.

You can charge at less than 2.2A, but it will take longer. Do not charge at more than 2.2A unless the lipo maker specifies that your pack can be charged at a rate greater than 1C.
