Main Cooling Unit – External View (Cont’d)
On the backside of the Aquaduct main cooling unit, neatly arranged across the bottom, are the connectors for attaching the two electrical cables and two water hoses. From left to right we have:
• DB-9M Power cable connector
• USB 2.0 connector
• Water Out
• Water In
Both water connections incorporate internal ball valves to shut off the lines when breaking connections. These are excellent, high quality valves that introduce virtually no flow restriction when opened (as apposed to quick-disconnect fittings that use built-in check valves). To use them however, you must install small plastic handles to turn the valves. When you are done you have to pop the handles back off and store them someplace where you won’t lose them. Too bad the design didn’t allow for just leaving the handles installed.

I/O Bracket Pass-Through
To help facilitate making connections to the computer system Aqua Computer includes a PCI slot I/O bracket that includes a power cable connector and two pass through holes for routing the tubing inside the PC.
Note: Unless you are using the optional standby power adapter cable (AQ-53047 sold separately) you must install the provided jumper on the two pins labeled J1_Standby.
