Looked like a full service down the street from where I live had a little fire? 4 Hoover Police suvs, 3 Fire trucks, 1 Fire suv and 1 Ambulance.
I believe it is Regal car wash on Lorna Road.

To get the Hamilton credit card acceptor out of the unit there are 4 bolts that hold it into the acw-5. Unbolt them and the credit card acceptor comes right out. Then remove 2 screws and the acceptor comes off the holder. I then mounted the new acceptor and reversed the process, tested my credit card and everything worked great! Now I can accept credit cards with my acw-5.
