Page 3: Cubex-Dhw, An Overview
User Instructions Controlling your unit You can easily set how much hot water you need using either the gauge (located on the side of the product), or the Mixergy app. 2.1.1 Quick start controls your unit using the gauge Your CubeX-DHW comes with an integral gauge which provides: a) A quick means of turning the product on or off via the top ‘power button’... -
Page 4: More In Depth Control Using The Mixergy App
Mixergy Cube X DHW, use the Mixergy App. For more details on the App, how to use it and where to find it, visit the Mixergy App page via the URL below or go to the Google or IOS store and simply search ‘Mixergy app’:... -

This can be configured using the Mixergy App as detailed through the links provided in Section 3.1.2. Having a higher setting temperature means that the product will store more energy. Having a lower setting temperature means less energy but also lower heat losses. -
Page 6: 2.2.2 Tank Overfill Pipe Connection
2.2.2 Tank Overfill Pipe Connection The Mixergy CubeX-DHW has an overfill pipe connection (Figure 4). The function of the overfill pipe is to act as a vent and prevent any pressure build up if the tank was overfilled or developed an internal fault. If water is continuously flowing through the overfill pipe this may suggest the tank has developed a fault or that the inlet valve is leaking. -

Page 8: Installation Guide
Installation guide Tank installation The following instructions must be read prior to the installation of the Mixergy CubeX-DHW, and work should only be carried out by a competent person. The installer should be aware of their responsibility and duty of care to ensure all aspects of the installation comply with all current regulations and legislation. - Page 9 Figure 5: Service clearance required around the Cube X-DHW MDC0039-04 Cube X Installation Manual Page 9 of 32...

Page 10: Connections
450mm (18 inches) is the minimum distance to make a solder connection from any of the inlet and outlet connections on top of the Mixergy CubeX-DHW. This is to reduce the possibility of any residual flux / solder contacting the stainless-steel corrugated tube inside the tank. Fluxes used for soldering or brazing are, by their nature and purpose, aggressive towards metals. -
Page 11: Mains Water Supply Pipework
4.1.3 Mains Water Supply Pipework For optimum performance, it is recommended that the incoming mains water supply should be capable of always delivering a minimum flow rate of 10l/min at a dynamic pressure of 1 bar or above. This should be sufficient for the operation of most sanitary appliances. - Page 12 Figure 6: Typical Pipework Configuration MDC0039-04 Cube X Installation Manual Page 12 of 32...

4.1.5 Fill loop connection Remove the isolation valve that is circled in figure 8 below. Figure 8: Filling loop Assemble the double check valve to the copper pipe. Ensure the orientation matches that in figure 9. There is an arrow on the valve which signifies the direction of flow. Figure 9: Orientation of double check valve Assemble the filling loop flexi between both valves as shown in Figure 10 below. -
Page 15: Secondary Return
4.1.6 Secondary Return Ideally the Cube X DHW should be installed as close as possible to all hot water outlets however, where this is not possible, and the pipe runs to outlets are excessive, a secondary return may need to be fitted. Figure 11 details a typical schematic of how to fit a secondary return to the hot water storage tank. -
Page 16: Over Fill Pipework
/ soil or atmosphere, the internal overfill kit can be used. Note: For the operation of the Mixergy CubeX-DHW unit, it is essential that the overfill pipe remains free of any blockages. A blockage in this pipe can lead to the failure of the unit. -

4.2.3 Timer control The black 3-core (L,N,E) cable labelled ‘TIMER CONTROL’ can be used to integrate the Mixergy Cube X DHW with any existing timers or controllers i.e. economy 7 timer or a dual channel controller. This cable detects an 80-240VAC signal and instructs the Cube X DHW to heat unless otherwise disabled in software. - Page 18 Figure 12: Primary supply MDC0039-04 Cube X Installation Manual Page 18 of 32...
