AQUADUCT
1.1. Overview about t e aquaduct
T e aquaduct is an an uncompromising solution. It as convincing de-
sign and a cooling performance w ic sets standards at a minimum
noise level. Furt ermore it is foolproof to andle, secure and compact.
It got t e name, since t e water runs over a kind of bridge at t e top
and falls down t en on t e ot er side.
T e aquaduct is a combination of passive and active radiator w ereby
bot variants can matc t e required cooling performance.
T e aquaduct 240 contains a 230 V pump and a dual radiator w ic is
equipped wit two 120 mm fans.
T e aquaduct 360 XT unites t e experience and developments of t e
last years into one product. It offers all known control and monitoring
functions of t e aquaero like flow-rate measurement, temperature mea-
surement, parameterizable fan control and USB connection to t e PC
software aquasuite are available, of course also network-compatible.
Moreover, t e vario lig t function (depending on temperature wit
alarm function) of t e aquaero was integrated directly into t e
aquaduct. T e PC software aquasuite also gives a grap ical overview of
t current state of operation.
To keep t e maintenance of aquaduct as low as possible, large water
tanks were integrated into t e cooling profiles. T roug t is t e refill of
water is minimized to an annual maintenance. Two ball valves were in-
tegrated at t e bottom and allow you to disconnect t e aquaduct wit -
out draining t e system. T eir advantage are better flow rates w ile self-
closing couplers are more restrictive.
Apart from electronic monitoring, two small balls in separate pipes s ow
t e function of t e aquaduct. A black ball s ows t e fill level w ile a red
ball s ows t e flow.
T e aquaduct comes wit a small circuit board for t e PCI slot. It sup-
plies t e aquaduct wit current and offers a connection for t e monitor-
ing functions. So t e PC can be turned off (optional accessories re-

quired) over a potential-free output of t e aquaduct in case of a mal-
function. Also t e fan voltage can be adjusted ere by jumpers (only
versions wit out integrated aquaero).
1.2. Information on t e assembly of a water cooling system
To enable cooling by water in sensible electronic devices, one basic re-
quirement as to be fulfilled: t e entire system as to be completely wa-
tertig t and long lasting. T is as always been our priority in developing
water cooling equipment. T erefore ig -quality plug-connectors are
used for our plug&cool-system. T ese rat er expensive, but by t e in-
dustry almost exclusively used pus -in connectors possess a pressure
resistance of more t an 10 bar, w en using suitable oses, guaranteed
by t e manufacturer. T is pressure is water cooling systems is far lower
t an t is value.
In addition to t e aquaduct cooling system you merely need t e water
coolers matc ing your PC's components. T e water cooler models
cuplex und cuplex PRO ave an acrylic glass lid, w ic allows for clean-
ing after long usage. It also enables an optical control of t e cooler and
t e water flow. No part is glued or soldered on t e entire cooler, w ic
makes it easy to dismantle. T erefore replacement of individual parts is
possible as well as t e fitting of new mounting plates e.g. w en c an-
ging t e CPU-type.
T e ig -quality rubber gasket is long lasting. S ould it ever wear out, it
can easily be replaced. Accessories can be obtained from us. Generally
t e gaskets s ould be replaced after 5 years or earlier if t e cooler is
frequently dismantled. T e t readed ose-connections of t e plug&cool-
system are made watertig t wit real rubber gaskets. T ey can be re-
placed later t e same way as t e main gaskets of t e coolers. T e op-
tional available barb connectors and 10/8 connectors are also made
watertig t wit a rubber gasket.
To optimally carry off t e eat of t e CPU t e cooler was made out of
copper. T e copper used is of very ig purity, w ic results in an out-

AQUADUCT
standing eat conductivity. T e surface of t e cooler is milled absolutely
planar, resmoot ing is entirely unnecessary.
Over time t e copper material will develop a protective oxide layer. T is
protects t e copper from furt er oxidation and as no influence on t e
function of t e cooler.
T e pump is one of t e most important parts of t e system. If it stops
working, t e processor will soon over eat extremely. As well as a failure
of t e fan in air-cooled computers, t is can result in t e destruction of
t e computer (or even a fire). T erefore a powerful and dependable
pump is essential.
T e pump of t e company E eim used in t e aquaduct stands out due
to a almost not audible run noise and a ig reliability.
In t e course of furt er tec nical development our products can be sub-
ject to c ange anytime. T erefore it is possible t at t e product you pur-
c ased doesn’t answer exactly t e descriptions or t e pictures in t is
manual.

2. Safety precautions
T e following safetey precautions ave to be observed at all times:
1. Read t is manual t oroug ly and entirely!
2. Save your data before working on your ardware in any case!
3. Be careful in removing existing conventional cooling devices. Es-
pecially w en removing cooling devices t at are glued on, t ere is a
risk of damaging t e ardware!
4. Depending on t e individual design of t e cooling system it could
be necessary to pass oses t roug t e side of t e case. In t is case
you s ould use t e ose protectors we offer or prevent ot erwise t at
t e oses will be damaged, especially by s arp-edged drilling oles!
5. Do not start your computer before you are absolutely sure t at no
water leaks from t e system!
6. Pay attention to t e care instructions at t e end of t is manual.
Specially avoid any contact of t e Plexiglas components wit
solvents!
7. Make sure t at your wall socket is protected by an FI-fuse!
8. Maintain a minimum distance of 0.5 m between t e aquaduct and
devices t at could react in a sensible way to magnetic or electromag-
netic fields!
9. Make sure t at t e computer can not be operated w en t e aqua-
duct is switc ed off. Use a multiple socket wit a switc for example,
via w ic you connect t e aquaduct AND t e computer to t e power
outlet! (230 V versions)

AQUADUCT
10. During operation of t e computer constantly observe t e tem-
perature of t e processor. Use software or ardware wit a warning-
or switc -off-feature for t is purpose, since a failure of t e cooling
system is not audible. S ould t e temperature of t e processor exceed
65°C (149°F) turn off t e computer immediately!
11. Use only t e coolant we specify. Ot er coolants can damage t e
system and cause leaking or decreased cooling performance.
12. Regularly c eck t e w ole system for leaks and replace all seals
wit signs of wear, every five years at t e latest. Suitable spare parts
can be purc ased from us.
13. T is product is not designed for use in life support appliances,
devices, or systems w ere malfunction of t is product can reasonably
be expected to result in personal injury. Aqua Computer GmbH &
Co. KG customers using or selling t is product for use in suc applica-
tion do so at t eir own risk and agree to fully indemnify Aqua Computer
GmbH & Co. KG for any damages resulting from suc application.
14. Secure t e aquaduct against overturns, particularly if c ildren or
domestic animals ave access to t e device! W en overturning t ere
is a risk of injury! In t e overturned condition t e function of t e
pump and wit t at t e complete cooling function can fail!
15. Depending on t e configuration of t e aquaduct it is possible
t at t e surfaces on t e outside get very ot! Take measures to pro-
tect t e device from touc ing, particularly if c ildren or domestic ani-
mals ave access to t e device!

4. Arranging t e elements of t e cooling system
On arranging t e elements of t e cooling system you s ould observe
t e following essential points:
•All elements ave to be flown t roug sequentially one after t e
ot er. A parallel assembly must not be carried out, since t e al-
location of t e water in t e different oses can ardly be pre-
dicted and single components could possibly not sufficiently be
cooled or even not at all.
•T e components can be in any order you like. T is as (almost)
no influence on t e cooling performance. Additionally it is wort
mentioning, t at t e difference in temperature of t e coolant
between t e in- and outgoing line of t e radiator is about 1-2
°C in an average system, meaning t at t e water just eats up
about 1-2 °C w ile flowing t roug all t e coolers.
•A complete cooling circle consists of t e aquaduct and one wa-
ter cooler at t e minimum.
5. Use of t e plug&cool connectors
Our plug&cool connection system makes a secure fit-
ting of t e oses possible wit out any tools. It is pres-
sure and temperature resistant. Please observe t e fol-
lowing instructions for t e fitting:
1. Cleanly cut t e ose to t e desired lengt .
T e ose s ould be cut evenly and cleanly avoiding
burs wit a s arp knife or a ose cutter (available in
our s op). After eac detac ment of t e ose from a
connector t e first two centimeters ave to be cut off to
guarantee a secure operation.

Gellie äuser Str. 1, 37130 Gleic en

AQUADUCT
2. Insert t e ose into t e connector up to t e limit
stop.
W en inserting t e ose a first limit stop will be felt
w ic as to be overcome wit some effort. If you want
to be on t e safer side you can mark t e ose wit a
felt pen up to w ere you ave to insert it. Depending on
t e connector it will be between 18 and 20 mm.
If t e ose as to be detac ed please do t e following:
1. Pus down t e black or blue plastic ring
on t e connector. For t is purpose you
can also use t e separately available AC
Multi-Tool. Slip it over t e ose wit t e
middle opening.
2. W ile pus ing down pull t e ose from
t e connector.
It is important to remove t e lengt of ose
w ic ad been inserted into a connector
before connecting t e ose again. It must
not be scratc ed to secure a perfect sealing of t e connector.
Now a few remarks about our ose. T e ose we use is made of poly-
uret ane. It as an outer diameter of 8 mm and an inner diameter of 6
mm. It makes bending radiuses of less t an 10 cm possible and is resist-
ant against many c emicals. A great advantage of t e system is t at it
seals t e ose on t e outside. T is allows t e use of t e complete dia-
meter, unlike t e use of ose barbs w ic are inserted into t e ose and
t erefore ave to ave a smaller inner diameter t an t e ose. Wit a
cross-section area of about 30 mm² t e system allows a sufficient flow
even in larger lengt s of ose.

6. Installation of t e CPU-cooler cuplex™, PRO and XT
6.1. Preparing t e installation of t e CPU-cooler
Now t at you understand ow t e connection system works, you can be-
gin installing t e CPU-cooler.
As mentioned earlier, wit any work you do on your computer, you
s ould always save your data before and. Disconnect your computer
from t e power supply. To protect t e sensible ardware you s ould
ground yourself before installation to avoid electrostatic destruction of
t e component parts. For t at purpose you can use a non-isolated water
pipe for example.
If you are upgrading an existing system
you ave to remove t e old cooler from
t e processor first. For t at purpose
please read t e manual of your cooler or
your mainboard. After removing t e
cooler you ave to clean t e die of t e
processor of any residue of old eat-
conductive paste. T en take a
razorblade or a plastic spatula and apply
a t in layer of our supplied eat-con-
ductive paste. T e core of t e processor,
also called “die”, s ould now be coated
by a omogeneous w ite layer. Make
sure t at no eat-conductive paste will
get on any ot er place and remove it if
necessary!
- 12 - Aqua Computer GmbH & Co. KG © 2007
Gellie äuser Str. 1, 37130 Gleic en
WARNING: If t e cooler gets stuck on t e surface of t e die it can
cause an edge of t e die to break off. T is results in an unrecoverable
destruction of t e processor. Avoid t e cooler to get stuck under any
condition. Even so-called spacers do not offer absolute protection. If
you are not confident in doing t is yourself, please ask a dealer to do
it for you.

AQUADUCT
T e principle of installation depends entirely on t e kind of fastening of
t e cooler. T at is w y we confine t e illustration of t e installation in-
structions mainly on description of a classic cuplex on a socket A main-
board. From t is description t e procedure for any combination of cool-
er and fastening version can be derived.
6.2. Installation wit t e “3-nose-mounting kit” - Socket 370, A
For t is fastening version two laser-processed
ig -grade brus ed steel s eets and four pres-
sure-springs are supplied wit t e cuplex. First
slide t e brus ed ig -grade stainless steel
s eets t roug t e slits in t e Plexiglas lid from
t e bottom. One of t e two brus ed ig -
grade stainless steel s eets only fits t roug t e
slit on one side of t e Plexiglas lid, t erefore
confusion is impossible. T e slig tly differing spring displacements on
bot sides cause t e pressure to finally concentrate exactly on t e pro-
cessor core (“balanced load”). Now insert t e pressure springs into t e
metal s eets above t e lid, as s own on t e
picture. T e cooler can be mounted onto t e
core of t e processor
now, w ic s ould
already be prepared
wit eat-conductive
paste as described
above. Make sure t at
t e core of t e processor is located centrally
below t e copper bottom of t e cooler and
t at t e longer part of t e Plexiglas lid w ic
sticks out is situated above t e detac ment
mec anism of t e socket. To avoid damage to
t e core t e pressure for mounting as to be
applied exactly perpendicular to t e surface of
t e core. Compress t e springs putting t e
t umb balls on t e stainless steel s eets from
above and taking old of t e lid from below

AQUADUCT
and ook t e stainless steel s eets under t e plastic noses of t e socket.
Avoid t e cooler to get stuck, since t is will risk a corner of t e die to
break off. Do not ook in one side after t e ot er!
6.3. Installation wit t e “4- ole-mounting kit“ - Socket 478, 775, AM2
S ould be more t an four feat ers included in t e screw set, please use
t e four „softer“ feat ers.
Wit t e so-called four- ole-mounting kit t e cuplex is fixed directly on
t e mot erboard wit four screws and pressure springs w ic are used
as screw springs. T erefore you ave to fasten t e four screws first. For
t at purpose detac your mot erboard from t e
computer case. In P4- and Xeon-systems t e
mostly black plastic mounting for air-coolers
as to be removed from t e mot erboard to re-
veal t e necessary drill oles on it. Next slide a
plastic was er over one of t e supplied stainless
steel M4 screws w ic you t en put t roug t e
oles adjacent to t e socket from below. Slide
anot er plastic was er over t e screw from above t e mot erboard and
t en screw on one of t e supplied stainless steel M4 nuts up to t e limit
by and. T e screw s ould now be fixed to t e board like a standing
bolt. Do t e same wit t e t ree ot er screws. Now t e cuplex can care-
fully and slowly be put onto t e standing bolts. Slowly slide it down until
it rests on t e prepared core of t e processor, wit out getting it stuck.
To protect t e Plexiglas of t e cuplex from getting scratc ed slide anot -
er was er over eac screw. Now put one of t e supplied springs over
eac of t e standing bolts.
Screw one of t e supplied knurled nuts
on eac screw about 2 turns, so it just
grips. For fastening t e springs, take
turns in fastening two knurled nuts at a
time placed opposite of eac ot er diag-
onally. During t is process make sure
t at t e spring coils do not touc eac
ot er, since t is can cause inadmissible
ig forces to build up. T e spring as to
- 14 - Aqua Computer GmbH & Co. KG © 2007

AQUADUCT
be fastened to t e extent, t at a slig t but visible
slit is left between t e coils. You can c eck t is by
sliding a piece of paper between t e coils, as il-
lustrated on t e p oto. If t is is not possible, you
fastened t e knurled bolts too muc and you
ave to loosen t em. Also make sure t at t e
cuplex does not rest on t e cover of t e barring
mec anism of t e socket, but on t e core of t e
processor.
6.4. Installation wit „2- ole-mounting kit“ - Socket 754, 939, F
S ould be more t an two feat ers included in t e screw set, please use
t e two „ arder“ feat ers.
For t e installation on At lon64 boards t e cooler is put toget er analo-
gly to t e four- ole-mounting kit but t is time only two screws will be
used ere since only two fastening oles are available on t e board. Be-
fore t e assembly of t e screws an existent plastic framework must be re-
moved if necessary. T e two bigger feat ers of t e mounting kit are
used as feat ers. Please gat er t e furt er procedure from c apter 6.3.
6.5. Examination and connection to t e cooling system
Now cut t e oses evenly to t e needed lengt wit a ose cutter or a
s arp knife and put t em onto t e connections of t e cuplex. T e pro-
cedure is described in c apter 4. Use of t e plug&cool connectors.

Finally c eck again if t e cooler rests plane on t e core of t e pro-
cessor and does not touc t e part of t e socket in w ic t e detac -
ment mec anism is integrated.
WARNING: A cooler w ic does not rest plane on t e core of t e
processor can cause destruction of t e processor in seconds w en t e
processor is switc ed on, since t e eat-capacity of t e core is too
small. Even TCS, bios or software-s utdown-tools can not prevent de-
struction in t is case!

AQUADUCT
T e special tubes of t e aquaducts must get separated before t e use. It
can be elpful to separate t e first millimeters wit a knife. T is area
must t en be divided off.
6.6. Proper connection of t e cuplex PRO and XT
Unlike c annel coolers, t e nozzle- and
microstructure coolers cuplex XT and cu-
plex PRO ave a predefined flow direc-
tion. For t e cuplex PRO t e water must
be conducted over t e connection
placed centrically directly onto t e mi-
crostructure, in t e case of cuplex XT t e
water is supplied over t e connection
connected to t e nozzle structure. T e
nozzles accelerate t e pouring water and provide a better eat transfer.
At bot cooler variants t e water is t en led away by t e lateral connec-
tion. T e cooler reac es its full cooling performance only w en connect-
ed in t is way w ile in reversed operation t e cooling performance is
sinificantly reduced.

7. Installation of t e PC interface circuit board
Install t e circuit board in a free slot of your case. T e slot does not
ave to ave any connection on t e mainboard.
Two jumpers are available on t e circuit board. A single jumper is con-
tained in t e scope of delivery w ic must be used for t e correct func-
tion of t e aquaduct like described in t e following! Two openings by
w ic t e water oses can be led into t e inside of t e PC are drilled in
t e slot metal. To prevent damages to t e tubes, rubber rings are pre-
assembled in t e openings.
7.1. FAN_JUMPER
Has to be set only for aquaduct variants wit 115 or 230 V pumps!
Wit t is jumper you can select w et er t e fans s all be powered wit
5 or 12 V. T e jumper must always be set on t e middle pin and an
outer pin. If t e jumper is removed, t e t e fans are turned off com-
pletely. In t is case it is ig ly recommend to c eck t e temperature of
t e system constantly as t e system will eventually over eat!

7.2. J1_STANDBY
Use only for aquaduct variants wit integrated aquaero! T e jumper
must be opened if you attac t e stand-by supply for t e aquaduct! To
use standby power, you need optional accessories (aquaero power con-
nect, item no. 53041 or 53047).
If stand-by power is not connected, t is jumper must be set in order to
ensure operation of t e included fans and safety functions!
IMPORTANT: If t is jumper is set, t en a stand-by supply must not be
connected!
7.3. RELAY
Only functional w en connected to aquaduct versions wit integrated
aquaero! T e screw terminal is connected wit t e potential-free switc -
ing contact and makes it possible to use t e extended security functions
of t e integrated aquaero, suc as turning off t e power supply in t e
t e case of an alarm. For using t ese functions you mig t need furt er
accessories w ic are not contained in t e scope of delivery of t e

9. Operation of t e ball valves
On t e bottom side of t e base are two ball valves for t e in- and outlet
connectors. T e levers s ould only be fitted temporarily during setup to
avoid unwanted operation by c ildren or domestic animals. It is not
necessary to use t e enclosed screws.
After equipping t e valves wit t e levers you can close t e valves. Turn
t e valve on t e left (see p oto) to t e left, turn t e rig t one to t e rig t
until t ey stop. W en bot valves are closed t e levers stand in line.
Opening is made by turning t e levers into t e origin position. T e open
condition is indicated by levers standing in parallel to eac ot er and to
t e waterflow. It is recommend to use sealing caps (our item number
63020) to prevent leakage from t e tubes w en t ey get disconnected
from t e aquaduct. T e tubes s ould always be disconnected and
closed one after anot er wit ball valves in closed position. T is will
considerably reduce t e amount of water leaking from t e tubes w ile
disconnecting.
