What else do I need to add to this unit to get soda water?

You'll need a couple extra items. A CO2 tank a regulator valve and a freshwater source. The regulator valve will mix the fresh water with the CO2 and produce carbonated water the carbonator does not actually create carbonation it amplifies it with a CO2 tank that is attached.

I need cooled soda water and i've already had the co2 tank and a chiller unit. where should the chiller unit be installed? after/before the pump?

After the pump in the fridge, the carbonator should not be installed in the fridge.

Why can't the chiller be installed before the carbonator?

Because the soda water won't stay chilled and will go flat.

Can the water source come from a reverse osmosis system? Was thinking of a way of purifying the water before it went into the system.

Yes. Make sure to have a storage tank (sometimes called an RO tank) installed between the filter and cabonator. The carbonator needs a quickly accessable surge of water when the float valve trips. If there isnt a tank to deliver this the pump will run until enough water trickles in from the pump. This will lead to premature pump failure. I put a dedicated ro tank for the carbonator and another for the filtered water tap. Works great. The carbonator cycle is nice and brief
