Step 6.
Bring the PC back up as shown in step 3 above (keep it angled at 15 to 20°), and complete filling-up the reservoir as necessary, and then close
the fill port. Complete the installation by securing the MCRES-1000 in the CD-Rom bay with the provided M3 screws, as shown in step 8 , paragraph A.

5. N OTES AND T ROUBLESHOOTING
Note (1) – Troubleshooting
While filling up the reservoir, the pump discharge tube does not fill-up with fluid: this will prevent the pump from priming and circulate
the liquid thru the circuit. It means that there is a significant pocket of air trapped in the circuit, preventing the fluid to rise up to the pump
discharge spigot. Make sure that your reservoir inlet and outlet barbs are oriented upwards. If your installation required that the reservoir be
mounted upside-down, temporarily dismount it from the chassis, this will allow the air to escape and travel up to the reservoir. If you are
using Swiftech’s “Radbox” simply remove the 4 screws from the half shell and rotate the reservoir until the filling procedure is complete, then
re-attach the radiator/fan/half shell assembly to the Radbox base.
Air keeps circulating into the circuit, long after the pump has primed:
o There is a significant pocket of air trapped into the circuit, check the radiator as indicated above, and/or the water-block.
o The fluid level is too low: top-off the reservoir to the appropriate level.
o One of the components connections is loose, or improperly tightened: Inspect each connection for traces of moisture, and tighten
all worm-drive clamps, and various connections in the circuit.
Note (2) - Starting the Power Supply when the motherboard is not connected
While the Internet contains numerous references on how to use a paper-clip to short-out pin 13 and 14 of the 20 pin ATX connector as shown below,
we nonetheless recommend instead using a power-supply tester. A wide variety of these common devices are available on the Internet (Google key
word: “PSU tester”), and among Swiftech resellers (www.frozencpu.com, www.Directron.com, www.newegg.com, etc.).

6. MCP350  P UMP S PECIFICATIONS
General Use
The MCP350™ pump is a magnetically driven centrifugal pump featuring a 12 V DC brushless motor. It requires no maintenance when
used with de-mineralized water and the appropriate anti-fungal additives. We recommend using 5% Swiftech’s HydrX
 as an additive.
The pump is designed to be connected to your computer power supply using the standard Molex 4 pin connectors. The pump features a
second connector (3-pin type) with only 1 wire. It is designed to connect to the motherboard CPU fan header, and to report the impeller
rotational speed (RPM sensor). Set your BIOS to monitor the CPU fan, and this will shut down the PC in case of pump failure.
Pump operating precautions
The MCP350™ pump should never be run dry, even for a quick test . You should always prime the pump with fluid before you start
operating it (see warranty note *). With filled lines, turn the inlet/outlets upward to ensure there is no air bubble in the impeller.
Use of coloring die or fluorescent additives containing particulate fillers will cause excessive wear to the pump’s impeller bearing (see
warranty note **).
