Now, you can re-install the MB inside the case.
3. Thermoelectric installation
IMPORTANT WARNING: Solder joints of the wires to the
thermoelectric module are extremely fragile. Bending the wires at their
root will break the solder joint, with no possible repair. Swiftech will
not honor the warranty for broken wires.
Connection to a dedicated auxiliary power supply
(recommended):
The TEC module is provided with “bare wires” to facilitate installation
with screw type terminals. We recommend the “Meanwell S320-12”
power supply, available on our website in the Thermoelectric
accessories section.
Connect red wire from TEC module to the +V terminal, and black wire
to the –V terminal as shown in figure 3 below:
Minimum requirements for a dedicated power supply: 25A @ +12 V.
If adjustable voltage is available: setting the voltage higher than +12V
is not recommended. Lower voltage, can be safely used, down to 9
volts.
Connection to an ATX computer power supply:
Important Warning: to connect the MCW5000-PT cooler to an ATX
computer power supply, you must carefully consider the existing
requirements of other devices connected on the +12V line. Connecting
to an underpowered unit will definitely damage the power supply.
Minimum requirements for an ATX computer power supply: 37A at
+12V in a typical computer setup.
If you are nevertheless going to connect the MCW5000-PT to a
computer power supply, you need to cut the wiring to one of the power
supply Molex connectors, and use a different connector between power
supply, and thermoelectric. This is because Molex connectors are not
rated for 25 Amps current, and may overheat.
Use a euro-style wire connector as shown in fig 4 below, or similar
device with a current rating of at least 25 amps. Connect red wire from
TEC module to +12V of P/S (Yellow wire), and black wire to black wire:
If you need wiring extensions: use 16 gage stranded wire. Connect
the extension to the existing wires with terminal splices, or solder the
butts, and insulate with shrink tubing.
4. Connect the MCW5000-PT block to the rest of the cooling circuit.
The block is designed in such a way that it will bleed itself automatically in any vertical orientation (computer standing-up).
5. Final inspection
Once the installation is completed, it is always a good idea to test the circuit for leaks, prior to powering up the computer. Troubleshooting
help is available on our web site at
www.swiftnets.com , or by calling customer support at 562-595-8009.
Note concerning removal of the tubing in quick-connect fittings: Push in collet squarely against face of fitting. A tube removal tool is
provided with the MCW5000-PT block. With the collet firmly held against the face of the fitting, the tube can be safely pulled out. Do not
attempt to pull the tube out without pushing squarely against the collet. This may result in damaging the fitting. Further details for using quick-
connect fittings are also available here:
