I can imagine! I'm not sure if Oasis has changed this aspect of the machine but ours circulated heated anti-freeze through all the rails AND through the spray arms. Like I said, our Typhoon was 20 years old and the high and low pressure spray manifolds weren't separated back then. However, the heated anti-freeze combined with an air blow out made for a great cold climate machine!
The Petit 360i really needs to be run in a bay with entrance and exit
doors. If the bay gets below freezing, you're going to spend a ton of money weeping the machine.
