PrefaceLEAKSHIELD is a worldwide unique leakage protection system for liquid coolingsystems developed by Aqua Computer. It actively generates an optimally comput-ed negative pressure in the cooling system which actively prevents the escape ofcoolant in the event of a leak.If a leak occurs, only air is sucked into the cooling system.For this purpose, an integrated vacuum pump is activated in a fraction of a secondin the event of a leak and continues to maintain the required vacuum.In addition, LEAKSHIELD uses a highly accurate sensor to detect and indicate evenminimal leaks. This allows countermeasures to be taken at a very early stage.The system is also able to determine the fill level in the reservoir.LEAKSHIELD was developed for the ULTITUBE reservoir series, but can also beused with other reservoirs, e. g. from the aqualis, aquatube or aquainlet series, viaan adapter set (LEAKSHIELD UNIVERSAL). For further information, please refer tothe corresponding instructions for the adapter set.LEAKSHIELD has an OLED display and a button control which allow the most im-portant functions to be controlled directly on the device.2. Scope of delivery ● One LEAKSHIELD device ● One internal USB cable (replacement part no. 53215) ● 34144 only: Two gaskets (replacement part number 94214) ● 34146 only: Two gaskets (replacement part number 94299)3. Safety precautionsThe following safety precautions have to be observed at all times:-4- Aqua Computer GmbH & Co. KG © 2021 Gelliehäuser Str. 1, 37130 Gleichen

aquacomputer LEAKSHIELD ● Read this manual thoroughly and entirely! ● Save your data onto suitable media before working on your hardware! ● This product is not designed for use in life support appliances, devices, or systems where malfunction of this product can reasonably be expected to re- sult in personal injury. Aqua Computer GmbH & Co. KG customers using or selling this product for use in such application do so at their own risk and agree to fully indemnify Aqua Computer GmbH & Co. KG for any damages resulting from such application! ● Never touch the membrane on the bottom side of LEAKSHIELD. Damage to the membrane can cause moisture to enter LEAKSHIELD and subsequently cause the unit to fail. If you notice any damage to the membrane, contact the Aqua Computer Technical Support ● Use only DP Ultra as coolant4. Requirements for the operation of LEAKSHIELDIn order to operate LEAKSHIELD properly, there are some principles to be ob-served when selecting the cooling system.LEAKSHIELD can only be used if the maximum pump pressure ressure in the system is lessthan 450 mbar. mbar This is the case for almost all systems with one pump. For systemswith more than one pump, this must be checked accordingly, e. g. by measuringthe pressure.The second prerequisite is that the tubing is suitable for the required vacuum. vacuumAs a broad rule, the outer diameter of PVC tubing should be at least 1.5 times theinner diameter of soft tubing.For PUR tubing, a factor of 1.2 is usually sufficient. Hardtubes are generally suit-able. Without information on compatibility, we recommend testing at slightly in-creased negative pressure and maximum water temperature before use.The components of the water cooling system have to be suitable for the operationwith LEAKSHIELD as well and have to withstand the necessary negative pressurepermanently. For Aqua Computer products this applies without exceptions. Forproducts from other suppliers, you have to check this before starting operation!It is also important that there is sufficient air volume in the reservoir. reservoir For safe oper-ation, there should be at least 100 ml of air in the reservoir.To ensure safe operation, only coolants of the DP Ultra series are approved foruse. Even if many other coolants are certainly trouble-free, we cannot guaranteethe function with these coolants.© 2021 Aqua Computer GmbH & Co. KG -5- Gelliehäuser Str. 1, 37130 Gleichen

LEAKSHIELD aquacomputerEspecially coolants with particles are able to clog or even destroy the membraneof LEAKSHIELD. Under no circ*mstances should coolants with flammable sub- sub-stances be used!5. Installation5.1. Installation on ULTITUBE reservoirs (34137)Hold the glass tube of the reservoir and remove the top lid from the reservoir byturning it anti-clockwise. Install LEAKSHIELD by screwing it onto the ULTITUBE. Af-ter installation, the display can still be rotated to a desired position.5.2. Installation on aqualis or aquainlet series reservoirs (34144/34146)Attention: Drain all coolant from the reservoir before unscrewing the top lid!Coolant will otherwise leak from both ends of the glass tube!Remove the top lid from the reservoir by turning it anti-clockwise. For security rea-sons, remove the glass tube and replace the gasket between reservoir base andglass tube. Realign the glass tube with the base of the reservoir and screw LEAK-SHIELD onto the reservoir using another new gasket. Make sure all componentsare properly aligned and fasten LEAKSHIELD securely to the reservoir. After instal-lation, the display can still be rotated to a desired position.6. Electrical connectionsATTENTION: Completely turn off your power supply or disconnect the mains pow-er cord from the wall outlet before connecting or disconnecting any cables to/fromthe device!6.1. Connector “USB”This connector is used for USB communication with a PC. Connect to an internalUSB header of your motherboard. Take special care to make sure the pin align-ment matches your motherboard!ATTENTION: To be able to operate LEAKSHIELD even when the PC is in standby,you must configure the USB port in the Bios settings in such a way that the powersupply remains activated. Alternatively, you can use external USB power suppliesfor the power supply. For a transportation, you can also use a USB power bankPin assignment: Pin 1 GND (black), optional Pin 2 GND (black) Pin 3 D+ (green) Pin 4 D- (white) Pin 5 +5 V (red)-6- Aqua Computer GmbH & Co.

You activate this by clicking onthe gearwheel at the very top right in the title bar.11.1. The settings wizardAfter calling up the wizard, a selection first appears in which you can choose be-tween the wizard for the basic setting and an editing of the current setting. Forcommissioning, leave the first preselected option selected and use the right arrowto call up the next dialog.In the reservoir dialog, select the reservoir you are using.LEAKSHIELD needs this information to be able to determine the fill level correctlyand e.g. to be able to calculate the volume change properly.For Aqua Computer products, you can select the reservoir used directly from thedrop-down selection field. For other reservoirs, you can enter user-defined valuesmanually.Settings for total volume, the remaining air volume at maximum fill level as well asat minimum fill level have to be made.In addition, there is the option to measure the fill level automatically on a regularbasis. If this action is activated, LEAKSHIELD will measure the level regularly whenchanges are made to the system (e.g. opening the reservoir) and after certaintimes.Caution: During the fill level measurement, the vacuum is released for a shorttime. At this time there is no protection against leakage!Now switch to the Pump dialog by clicking on the arrow symbol.The pump used is the most important information for the operation of LEAK-SHIELD. The pump type and the speed of the pump are used to calculate the pres-sure of the pump at the operating point and LEAKSHIELD can adjust the vacuumto your system accordingly.The aquasuite automatically searches for Aqua Computer pumps in your system inthe background. If connected pumps are found via USB or aquabus, the correctpump is usually preselected.- 16 - Aqua Computer GmbH & Co. KG © 2021 Gelliehäuser Str. 1, 37130 Gleichen

aquacomputer LEAKSHIELDFor Aqua Computer pumps that are not found automatically, you can select theinstalled pump directly in the drop-down selection.Other pumps can be configured via the user-defined setting. In this case you needinformation about the maximum pressure of the pump and the maximum speed.In addition, the aquasuite tries to find a data source for the speed of the pump. Ifthere is no selection in the data source field or if the selection is wrong, you cancorrect it manually.The pump speed is important to automatically adjust the vacuum to the operatingpoint of the pump.Now go to the "Flow" section.A flow sensor is not mandatory for the correct function of LEAKSHIELD. However, ithelps to calculate the operating point more precisely and to be able to reduce thevacuum further.LEAKSHIELD automatically searches for Aqua Computer flow sensors. If sensorsare found, the most useful sensor is automatically selected.You can also make a selection manually using the "+" button or perform a newsearch for sensors using the "Search Flow Sensor" function.The next page "Pressure" allows you to skip the previously calculated values. Thisfunction is only useful for experts and is not recommended.The selection "Use adaptive pressure" is preselected and lets LEAKSHIELD adap-tively calculate the optimal values at any time. If this selection is deactivated,LEAKSHIELD works with the maximum possible pressure for the selected pump asthe operating point.By selecting "Time controlled generation of negative pressure" you can select twotimes at which LEAKSHIELD will build up the negative pressure again. This allowsyou to schedule the operating noise of LEAKSHIELD at a time that does not disturbyou.After leaving this page, you will reach the "Standby" section.When booting from standby, no data can be sent to LEAKSHIELD via USB yet.Therefore LEAKSHIELD needs defaults for the operating point of the pump. Youcan select this data via speed and flow defaults. In addition, current values can betaken from the assigned data source. If you do not know the data, you should notactivate a reduction of the vacuum in standby in the following option© 2021 Aqua Computer GmbH & Co. KG - 17 - Gelliehäuser Str. 1, 37130 Gleichen

LEAKSHIELD aquacomputerIn the standby of the PC the negative pressure can be reduced significantly if thepump is switched off with the PC. To enable this, you can activate the correspond-ing function here. The negative pressure in this condition can also be selected.Now switch to the LEAKSHIELD "Mode" page.You can now select the operating mode of LEAKSHIELD. As a most common rule,the "SHIELD" mode should be selected. If the vacuum of LEAKSHIELD is not suffi-cient to protect your system (too strong pump, several pumps), you can use themode "MONITOR". This will be indicated by corresponding warnings in the upperpart of the page.The "RELEASE" mode only leads to a pressure equalization to the environment.You will then be taken to a "Summary" of the selected settings and can check themonce again. Possible notes and warnings are displayed at the top of the table.To change settings once again, you can navigate through the pages by pressingthe arrow icons. The checkmark symbol on the Summary page transfers the set-tings to your LEAKSHIELD. If you cancel the wizard by clicking the "X" icon (topright), the previous settings will be saved.11.2. The "Test" actionIn the Test mode, the desired negative pressure is requested first. You can performa leak test with negative pressures between 80 and 450 mbar.Then LEAKSHIELD starts to prepare the test and to create the negative pressure.Once this process is complete, LEAKSHIELD will show you a graph of the pressurechange over time. You can use the "Reference" button to select the current pres-sure as a reference. In addition, the data source of the diagram can be changed.The absolute current negative pressure, the pressure difference to the referencevalue and the current pressure change are available for selection.With the mouse you can enlarge areas in the diagram.By pressing the "Cancel" field, you leave the test mode again.11.3. The "Measure fill level" actionIf you activate the fill level measurement by clicking on the symbol "Measure filllevel", a bar graph appears in the lower area which shows you the progress of themeasurement.To do this, LEAKSHIELD first releases the negative pressure and then generates alow negative pressure of approx. 100 mbar. The result of the measurement is thendisplayed.- 18 - Aqua Computer GmbH & Co. KG © 2021 Gelliehäuser Str. 1, 37130 Gleichen

aquacomputer LEAKSHIELDNote: There is no sufficient leakage protection during the level measurement. Ifyou have reason to believe that your system is not completely tight, you should notactivate the level measurement!11.4. The "Deaerate system" actionAfter activating the action "Deaerate system", two progress bars appear. The firstshows the progress of the current cycle, the second the overall progress.During this action, negative pressure is cyclically built up and released again. Thisremoves trapped air in the system step by step through expansion and compres-sion.11.5. The "Refill system" action fill--During filling, the water pump must be switched off. Therefore, we recommend filling by pressing the button on LEAKSHIELD and while the PC is on standby!If the action "Refill system" is selected, LEAKSHIELD generates a negative pressurebetween 250 and 300 mbar. Coolant can be sucked into the system by this.Pressing the "Pause" button pauses the pumping action, but the vacuum is not re-leased. This prevents coolant from flowing back into the container.If the process is terminated by pressing the "Exit" button, LEAKSHIELD switches tothe previously selected mode.12. Sensor configuration Select “Sensors” from the device list below the “LEAKSHIELD” entry. In the upper area of the window, the 18 usable sensors are displayed with the actual measured value. In the lower area of the window, the configura-tion of the selected sensor can be made.There are local sensors, sensors with extended configuration and software sensorsin this selection.The local sensors are measured values of the sensors of LEAKSHIELD. For thesesensors, only the name and log interval can be selected.The sensors with extended configuration are sensors for which extended settingscan be made and which have influence on the operation of LEAKSHIELD. Thesesettings are also possible via the wizard.© 2021 Aqua Computer GmbH & Co. KG - 19 - Gelliehäuser Str. 1, 37130 Gleichen

LEAKSHIELD aquacomputerThe software sensors (sensor 1-12) on the other hand are placeholders for data tobe transferred from your PC to LEAKSHIELD via USB.Here all data of the aquasuite (incl. hardware monitoring and other Aqua Com-puter devices) are available. In addition, a scaling factor and an offset can be se-lected for these sensors.The data transmitted in this way can later be shown on the display of LEAKSHIELD,for example, or serve as a data source for RGBpx effects.Please note that this data is only available when the Aqua Computer backgroundservice is running and a USB connection to LEAKSHIELD exists. During the bootprocess, for example, this is not the case!The most important sensor values of LEAKSHIELD:12.1. PressureThe first displayed sensor indicates the current negative pressure in mbar.12.2. Fill levelThe second displayed sensor indicates the current fill level of the reservoir in per-cent.In the configuration section you have the possibility to start the fill level measure-ment and to adjust the settings given in the wizard for this section. You will findmore information about the details in chapter 11.1 (Reservoir).We recommend to make the settings only through the wizard.12.3. Volume changeThe third displayed sensor provides information about the volume change in ml/h.This value can give you information about smaller leakages. However, this valuealso changes when the temperature of your system changes.12.4. Pressure changeThe fourth displayed sensor provides similar information as the volume changevalue, but here the pressure change is given in mbar per minute.12.5. Pump speedThe fifth displayed sensor shows the current pump speed (if available). This value istransmitted via USB from the Aqua Computer background service to LEAKSHIELD.You can customize the sensor name and log interval.- 20 - Aqua Computer GmbH & Co.

aquacomputer LEAKSHIELDIn the configuration you can also view the settings of the wizard for the "Pump"area and change them directly. You can find more information about the details inchapter 10.1 (Pump). However, we recommend to make the settings only using thewizard.12.6. FlowThe sixth sensor displayed is the flow measurement value of your system (if avail-able). This value is transmitted via USB from the Aqua Computer background ser-vice to LEAKSHIELD.In the configuration, you also have direct access to the settings made in the wizardin the "Flow" area. In addition, you can adjust the sensor name and the log inter-val.You can find more information about the details in chapter 11.1 (Flow). We rec-ommend that you only make the settings using the wizard.12.7. Software sensorsThe last twelve sensors in the list are software sensors and can be used to transmitsensor data that is not physically available to LEAKSHIELD from the computer byUSB connection.Select the appropriate unit for each configured data source. For manipulation ofthe displayed sensor value, a scale factor and an offset may be configured. Datafrom third party software regularly requires the scale factor to be adjusted.Transmission of sensor data via USB interfaceDuring installation of the aquasuite, the background service “Aqua Computer Ser-vice” is also installed. This service supplies various data from PC components andimported data from aquasuite web, additionally sensor data provided by third par-ty software can be accessed. In order to access third party software data, the thirdparty software has to be correctly installed, configured and running.Currently, the “Aqua Computer Service” supports data transfer from “HWiNFO”(REALiX, Freeware, www.hwinfo.com) and “AIDA64” (FinalWire Ltd., subject to li-cense fees, www.aida64.com).HWiNFO automatically exports all sensor values, the “Sensor Status” Window hasto be open.In the AIDA64 preferences menu, writing to WMI must be activated in the “externalapplications” sub-menu:© 2021 Aqua Computer GmbH & Co.

aquacomputer LEAKSHIELDFor each page you can select whether it should be displayed in standby of the PCand whether it should be displayed in normal operation.This allows a different selection of pages to be displayed for standby and opera-tion.13.2. Display settingsThe brightness of the display as well as an automatic change of the display pagescan be configured.The brightness can also be set for inactivity (no user interaction) and the displaycan be switched off completely.In addition, settings can be made here as to whether and after what time the dis-play pages should change automatically.The other options allow the display to be rotated by 180° and the display to be in-verted.Automatic inversion is activated at the factory. This significantly reduces the burn-inof permanently activated pixels, which is typical for OLEDs.As with all OLED displays, the brightness of active pixels decreases over time. Forhom*ogeneous wear of all pixels, the display can be operated inverted half thetime. To compensate for existing wear, the inverted mode can also be activatedpermanently.The last option available here is the automatic shutdown of the display in standby.This option significantly increases the life span of the display!14.
