1. Condensation control measures

The following instructions are crucial to long lasting & reliable operations. Do not skip these steps, and do not take shortcuts. Permanent damage to your components is likely to occur otherwise.

a. Motherboard preparation

i. Conformal coating application: This step will positively ensure that any micro condensation occurring on small surface

mount components will not corrode or short-circuit the motherboard.

Procure a spray can of silicone conformal coating. We use M.G. chemicals Acrylic Conformal Coating, part # 419B-340g – A list of retail distributors carrying this item can be found here (US): http://www.mgchemicals.com/distributors/us/index.html Canada: http://www.mgchemicals.com/distributors/canada/index.html recommended for their ease of use. The product can also be purchase at our online store here (effective 7/15/04):

. Equivalent products can also be used. Sprays are

Figure 1

Spray the back of the motherboard, concentrating on the area immediately behind the CPU. Allow time to dry, per manufacturer specs.

Figure 2

Use masking tape to protect the CPU socket, and any connector sockets in the immediate vicinity of the socket. A double layer of tape is recommended for the CPU socket.

Spray the area immediately surrounding the socket. It is not recommended to spray further than the area circled in the above picture. Allow time to dry per manufacturer specs.

ii. Dielectric grease application: This step will ensure that condensation does not form inside of the CPU socket.

Procure a tube of dielectric grease. We use Luberex grease, available on our web site here:

inside the socket, some hydraulic pressure lift may occur: for this reason, make sure that the processor sits perfectly flat, and is inserted all the way into the socket.

into the center of the processor core.

the central area of the socket is completely filled with grease.

Securing the MCW5002-AT cooler to the motherboard:

 Initial check: make sure that the retention clips are at their lowest position by

tightening the 2 spring loaded Philips screws until the springs are fully compressed (do not over-tighten)

 Engage one side of the clip under the CPU socket retention lugs  Gently pull the water-block in the opposite direction and push it down to

catch the opposite set of socket lugs. The clip will snap underneath the socket lugs.

 Firmly press the base of the clips (through the gaskets) between middle

finger and thumb as shown in Figure 7 to compress them against the socket (this will prevent the clips for disengaging themselves from underneath the tabs at start-up) then gradually and alternatively loosen the two spring loaded Philips screws to secure the water-block.

 Continue backing off the screws until the head of each screw completely

clears the top of the bracket, as shown figure 8.

2. Electrical 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.

a. Recommended installation: Connecting to a dedicated

auxiliary power supply

 Minimum requirements for a dedicated power supply

are 25A @ +12V.

 Your TEC module has been measured to draw 18

amps at 12 volts. For this reason, we recommend using the “Meanwell S320-12” auxiliary power supply, available on our website in the Thermoelectric accessories section.

 The TEC module is provided with “bare wires” to

facilitate installation with screw type terminals such as featured in the S320-12 power supply

 Connect red wire from TEC module to the +V

terminal, and black wire to the –V terminal as shown in figure 9.

 A complete installation guide for the S320-12 power

supply kit is available here:

http://www.swiftnets.com/products/installationguide_S 320-12kit.pdf - This kit includes a wiring harness and

a relay switch to synchronize the power to the S32012 with your computer, which is a highly

recommended (read below)

CCRRIITTIICCAALL RREECCOOMMMMEENNDDAATTIIOONNSS MMUUSSTT RREEAADD!!!!!!

Never run a thermoelectric module without coolant flowing in the circuit. This will result in catastrophic failure of the cooling element, and

may cause any/all of the following:

 Tubing to burst open due to coolant overheating  Permanent failure of the Peltier module  Permanent damage to the CPU and/or motherboard due to

excess heat

It is highly recommended to dedicate the auxiliary power supply for the thermoelectric module to the computer power-supply, so that the

Peltier module will never run by itself without cooling fluid.

For this purpose, we recommend using the following accessory, available in our online shopping cart: PRS Kit II. Includes: Relay Switch Circuit

board AC socket, S/S socket cover, power cord. This relay switch is rated

for 110 to 220~240 volts and up to 50A inrush current. It is suitable for use with the S-320-12 Meanwell power supply recommended above.

If you run your computer unattended for extended periods of time, it is also a good practice to setup an alarm temperature, which will shut

down the computer in case the CPU overheats. Such alarm/shut down process should be tested as functional.

WARNING! Wires from the thermoelectric module do get

hot (this is normal). Make sure that the wires do not touch devices that are heat sensitive, such as vinyl tubes for example. Heat from the wires may cause the vinyl to deform, and/or burst.

Installation of the cooler to the motherboard is now complete!

b. Connecting to your computer power supply:

Important Warning: to connect the MCW5002-AT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.

c. Connecting TEC wires to the power supply:

Use the provided euro-style wire connector as shown in fig 11 below, or a 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:

Minimum requirements for an ATX computer power supply: 36A at +12V in a typical computer setup.

When you connect the MCW5002-AT to an ATX 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

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.

for 18Amps current, and may overheat.

3. Hydraulic Installation

 The MCW5002-AT is shipped with ½” barb to 3/8” NPT nylon fittings. These fittings should be installed using Teflon tape or

plumbers “goop”. If fittings need to be replaced for a difference tubing size, do not use brass fittings, because of the galvanic corrosion that will take place between copper or brass and the MCW5002-AT aluminum housing. Always use nylon fittings.

 Inlet and outlet are interchangeable.  Type of Coolant:

 For best performance, use 95% distilled water, and 5% Swiftech brand “HydrX” corrosion inhibitor (available here:

http://www.swiftnets.com/store/category.asp?CatID=2

, under the “accessories” section).

 In all cases, you must use Distilled water and a corrosion inhibitor with the MCW5002 water-block. Regular automotive

anti-freeze is acceptable. Automotive manufacturers recommend that not less than 25% is used.

 NEVER use tap water, even for a short-term test.  Not following the above instructions constitutes misuse (*) of the product, and will void your warranty.

4. 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.
