Baggage storage for 3 hours at PVG?ATM location

I will be transiting PVG, arriving on a Royal Brunei flight at 14:45 (T2), departing Delta at 21:20 (T1). I need to store my bags while I take a ride on the Maglev. Where would be the best baggage storage location for this. I will need to get CN for this at a China Construction Bank ATM, where is this ATM located?
thanks
