Uponor Smart Ends Uponor Smart end system enables the installation of fittings onto bespoked brackets with an easy,secure connection capability , allowing fixation with only one hand. Brackets can be used in dry walls or Timber partition walls providing a sturdy base for mounting the wall plate elbow. Flat brackets can be used for on-wall installations still giving the smart end fixation.

Wall plate elbows can be mounted vertically onto brackets or at 45 angles to provide flexible installation around obstacles , I.e Waste pipes.

The Smart End concept improves first fix installations with easy pressure test facilities and clear fixation locations for building work required.

Wall thickness variations can be overcome with ½ inch threaded tap extensions.

Uponor angle valves and threaded nipples make for final connections to appliances.

Smart end products are available in Uponor MLC + Q&E pipe systems.

Uponor Smart End – Hygiene system Uponor Smart end range has been developed with the introduction of the U Smart End, with the same installation advantages as the existing Smart End range.

Uponor hygiene system allows two unique ways to design Domestic pipework system eliminating deadlegs.

Serial Installation.

The serial installation prevents the collection of water in the feed lines of appliances that are rarely in use, e.g. outdoor taps, washing machines and showers. In this system, the appliances are connected by means of Uponor U-end elbows that are routed directly to the next appliance, therefore excluding any stagnation of the water in the branches leading up to the appliance. By placing a high use item at the end of the serial installation (usually a toilet or basin) this allows for effective elimination of dead legs. The Uponor Smart end can then be terminated with a Uponor angle valve allowing direct connection to Taps with flexible ends whilst complying with Water bylaws with isolation.

Loop Installation.

The Uponor U-end elbows can also used to connect the taps in a loop installation, like the serial system the pipe runs directly to the next tap. However, the piping is routed back from the last appliance to the feeding pipe. The advantage of the loop installation is it does not matter which appliance is used, any flow will flush the other appliances.

Uponor loop system also supplys the appliance from both feed pipes when operational ,allowing increase flow potential in the system, this may allow for selection of smaller pipe sizes in the installation. The Uponor Smart end can then be terminated with a Uponor angle valve allowing direct connection to Taps with flexible ends whilst complying with Water bylaws with isolation Trace Heating

Trace heating can be used in conjunction with MLC pipework. The internal aluminum pipe guarantees an even heat distribution throughout the pipe; the temperature limit is usually 60°c. The heater band is to be mounted as per the manufacturer’s instructions; UPONOR MLC is rated as plastic pipework.

Pipe Expansion UPONOR MLC has a thermal expansion rate which is significantly lower than other plastic pipework systems. The thermal expansion of coefficient is (0.025 mm / (m x K)).

Fixings Fitting and equipment connections as well as the connection of measuring and control devices are to be installed torsion-free. All pipes are to be installed in such a manner that the thermal length variation (temperature change) is not obstructed.

No trays may be used if UPONOR MLC pipes are installed open on the ceiling with clips. The following table represents the maximum mounting distance “L” between the individual pipe clips for different pipe dimensions.

Type and distance between the pipe fastenings is dependant on the pressure, temperature and medium. Dimensioning of the pipe supports is to be determined from the total mass (pipe weight + medium weight + insulation weight) in accordance with generally accepted rules of technology. It is recommended to set the pipe supports, if possible, in the proximity of the fitting and connections.

Uponor MLC & Secondary circulation.

Secondary circulation is classified as a system that:    

Provides potable hot water Maintains a temperature in excess of 65°C Replenishes water used in outlet with fresh water (oxygenated water) .

Is a pumped circulation system.

If all four of the points are covered your system is classified as a secondary circulation system (or recirculation system). Plastic pipeworks manufactured under BS-7291-1/3 2010 cannot be used in secondary circulation applications. Uponor MLC pipe can be used in secondary circulation because it is manufactured under a different standard (BS EN ISO 21003-1 2008) also because of the aluminum layer within the pipework it has a higher tolerance than a standard PEX pipe system. Although there still should be appropriate water temperature control on the system to ensure the water temperature does not exceed 70°C as stated in our guidelines.
