The complete system from one source

Whether it is tap water, radia tor connection or compressed air applications the Uponor MLCP system is the perfect solution. The comprehensive program permits the complete installation from the house connection line to the consumer. The installation is simple and economical: The core of the system, i.e. the Uponor Unipipe MLC pipe and the relevant ttings, are manufactured in house and therefore perfectly coordinated. Through the inherent stability of the pipe and the low linear expan-sion, only a few mounting points are necessary the practical advantage for a safe and fast installation. The Uponor MLCP system is rounded off by a well thought out Tool program: from pipe cutting tool over bevel-ling tool up to pressing tools.

Basis for your professional installation

Permanently watertight, together with a long service life, are the most important requirements that are demanded today from a reliable and high-quality installation. Uponor as a leading manufacturer of plastic pipes for house construction and municipal technology ful ls these requirements without reservation with its Uponor MLCP system. With this system we offer you the security that is so impor tant for your installation.

The Uponor MLCP system

Tested Quality

With the Uponor MLCP system you install tested and certi ed quality. Thus you observe all required building regulations, including re protection, sound protection and thermal insulation regulations. The system technology is also here particularly long-lived and safe, certi ed by numerous tests and licences.


With our 5 layer composite pipe we developed a product with a future, which combines the bene ts of both metal and plastic pipes. Product bene ts are obtained that cannot be surpassed: The inner aluminium pipe is absolutely safe against oxygen penetration. It compen-sates for the snap-back forces and the linear expansion caused by temperature changes. The basis of the system is simple, safe and fast pipe installation: simply bend by hand, cut to length, bevelling, join together, press done!

Corrosion resistance

The Uponor Unipipe MLC pipe con-sists of a long itudinal safety welded aluminium pipe, to which an inner and outer layer of high temperature resistant polyethylene is applied (in accordance with DIN 16833). All layers are permanently bounded to-gether by means of an intermediate adhesive layer. A special welding technique guarantees a maximum of safety. The thickness of the alu-minium selected for the Uponor Unipipe MLC pipe is exactly adapt-ed to the compressive strength re-quirements as well as the bending capability.

The Uponor Unipipe MLC pipe has a comparatively low linear expansion due to the plastic lms rm bond to the aluminium

Fast, simple, safe: The connection technology for Uponor Unipipe MLC pipes

Extensive program from a single source

Uponor shows its strength in the development and manufacturing of a tting concept precisely coordi-nated to the pipe being used. The pipe tting program with its cou-plings, elbows, T-pieces and large number of practical system compo-nents satis es your every need: Pressed or compression both methods can be used and ensure durable watertight connections.

The exibility of the Uponor Unipipe MLC pipes can often re-duce the number of elbows needed for the installation. This substan-tially lowers material costs as well as reducing installation time. Further bene ts are shorter tted length and an increased installation safety.

Even with complicated applications you nd the right connection in Uponors extensive tting program whether press or compression.

Uponor MLC press ttings

Connections can be made within seconds with the patented Uponor press system. Complicated connec-tion techniques such as a welding or soldering are not necessary.The connection technique produces permanent watertight press, clamp and compression connections, as is con rmed by the SKZ test reports and DVGW certi cates.

Auditable metal press ttings Composite tting made from PPSU


Metal MLC press tting with coloured stop rings

The Uponor press tting 14-32 mm is a new generation metal press tting. Because here reliable testing is standard. The tting is manufac-tured with optimized support sleeve geometry; a stop ring and press jaw guide ensures simple, skew free pressing. O-rings ensure an abso-lute watertight connection between the support sleeve and inner pipe wall. The system is certi ed by DVGW.

The installation friendly metal press tting is designed in such a way that, during the prescribed pressure test, water leaks from the un-pressed connections or the tting separates from the pipe. That means, simply press and a durable and watertight connection is guar-anteed.

Coloured stop rings on the practice proven installation friendly Uponor press ttings are the sign of the new Uponor tting generation. Each nominal size from 14 to 32 mm has its own colour this brings clarity to the building site, the warehouse as well as to the wholesaler.

Test reliability is built-in at the factory: The Uponor MLC press ttings 14 32 mm

1. ApplicationThe press jaw is placed onto the press guide of the press sleeve.

2. PressingDuring the pressing procedure the stop ring breaks into pieces and falls off of the press sleeve.

3. TestingThe missing stop rings reliably mark a success-ful connection. This can be recognized at a distance of many metres.

4. InsulationContinuous pipe insulation such as Tubolit can be easily pushed over the obstacle-free connexion.

If a connection is still not pressed, this is shows up doubly when pressing. The coloured stop rings are still attached. Additionally tting is designed in such a way that during the pressure test water leaks out. Now simply press and the connection is permanently tight.

Measures for inhibiting the growth of legionella

Conditions must be established that inhibit an unhealthy concentration of legionella in hot water tank systems and their attached warm water distribution systems.

Legionella is rod-shaped bacteria, which naturally occur at low con-centrations in fresh water e.g. lakes, rivers and occasionally also in tap water. Approximately 40 forms of the legionella bacteria are known. Some legionella forms can cause infections through the inhalation of contaminated aerosols ( ne water

droplets) e.g. while showering or through moisturizers in air-condi-tioners. For people with health problems e.g. weakened immune system, chronic bronchitis etc. this can lead to pneumonia (legionella pneumonia or legionnaires disease) or to Pontiac fever.

According to DVGW worksheet W 551 the infection risk is a direct function of the temperature of the water from the tap water installa-tion. The temperature range in which increased the legionella growth appears is appropriate between 30 C and 45 C.

Based on the present level of know-ledge, the workpaper describes the necessary technical measures for the reduction of legionella growth in tap water installations. Additional measures are described for the rehabilitation of contaminated tap water systems.

Circulation systems

Warm water distribution systems in which warm tap water is constantly available at the taps must main-tained permanent hot water circula-tion. For the operation of circula-tion systems, the conditions as stipulated in DVGW worksheets W 551 and W 553 must be maintained in order to avoided the above mentioned health risks.

Requirements

The complete warm water distribu-tion system is to be operated in such a way that on the one hand the warm water leaves the tap water heater with at least 60 C and returns to the heater with a tem-perature loss of no more than 5 K. On the other hand a suf cient warm water volume ow must be present in all circulation lines. The DVGW worksheet recommends the operation of a circulation system with a water temperature of at least 57 C at the end of each return line. The required ow rates are calculated in accordance with DVGW worksheet W 553.

This worksheet contains three calculation procedures:

A short procedure for small systems (e.g. one and two family houses), with which no calcula-tions must be made.

A simpli ed procedure for all system sizes with the goal of supplying a calculation method which supplies suf ciently accurate results for the draft and the implementation without excessive effort.

A differentiated procedure for all system sizes with the goal of achieving a better approximation of the real operational condi-tions, particularly for large systems.

The mentioned calculation methods should be taken from the DVGW worksheet W 553. The Uponor HSE calculation software is available for these calculations.

Protection of tap water


Uponor Aquastrom T plus

Thermostat preset for circulation conduit

Uponor Aquastrom T plus is a preset thermostat for circulation conduit that conforms to DVGW worksheets W551 and W553. It regulates the circulation water temperature in the recommended range of 55 C to 60 C (max. control range 40 C to 65 C; accuracy +/- 1 C). The valve automatically supports thermal disinfection. The volume ow rises approximately 6K above the set temperature and reduces itself, inde-pendent of the temperature set, starting from approxi-mately 73 C on the remaining volume ow. The valve thereby optimally supports the thermal disinfection of the circulation system. The maximum volume ow can be preset and locked, independent of the temperature set. The valve is made from red brass and is equipped with a drain valve with a hose mounting that allows the circulation branch line to be emptied for maintenance purposes. Temperature monitoring is possible with thermometers or temperature sensors. The temperature setting is protected against change by a seal cover. The temperature value set can still be read.

The Uponor Unipipe MLC pipe is suitable for use with trace heating. The inner aluminium pipe ensures uniform heat distribution around the pipe, the customary temperature limitation of 60 C by the manufac-turer is to be respected. The xing of the heating band is to be done according to the manufacturers instructions, whereby the Uponor Unipipe MLC pipe is to be classi ed as a plastic pipe.

You must make sure that the water can expand correspondingly if Uponor Unipipe MLC pipes with a self-regulating heating band are permitted. If this is not the case,

e.g. as with tank outlets to the warm water distributor, short lines to the usage points or with house connection lines that only bypass one story, damage of the Uponor of pipe due to the high increase in pressure cannot be ruled out.

For these cases suitable safeguards are to be taken, e.g. the installation of a suitable safety valve or expan-sion vessel.

Note:The pressure increase of the components due to the use of heat-ing tape is to be closely watched. Suitable safety precautions are to be planned that ensure pressure equalization. The manufacturers assembly guidelines and installation notes for the self-regulating heating band must be observed.

Use of trace heating

Connection to a instantaneous water heater

Due to their construction, hydrauli-cally controlled, electrical and gas red ow heaters can build up high temperatures and pressures, both in normal operation and as a result of a failure, which can cause damage to the pipe system. The Uponor MLCP system may only be directly connected to electronically control-led equipment. The manufacturers instructions must be observed when using electronically controlled equipment to heat tap water.

Connection to a hot water tank

Generally it must be ensured when connecting hot water tanks (par-ticularly with direct red hot water tanks, solar storage tanks and special constructions) that in normal operation as well as in the case of a failure, the operation limits of the Uponor Unipipe MLC pipe are not exceeded. This applies in particular to the maximum warm water outlet temperature, which is to be checked at start-up or be obtained from the manufacturer. In the case of doubt, suitable safety precautions are to be taken (e.g. installation of an industrial water mixing valve).

Mixer connections

Fitting connection installation must be torsion-proof (e.g. by xing the press tap elbow on mounting brackets or mounting plates).

Connection to instantaneous water heaters, hot water tanks and mixer


Humidity protection

The humidity protection required in sanitary facilities is regulated by DIN 18195-5 Water-proo ng against non-pressing water. The following implementations are limited to humidity protection within the area of sanitary ttings and wall bushings, e.g. within the area of dry lining panelling.

Each sanitary facility can be divided in two humidity classes:

Humidity protection in the area of sanitary ttings and wall penetration

With concealed ttings, a seal must be made to the brick-work or the

opposite dry lining panelling with a suitable humidity seal. The tiler integrates these in accordance with the generally accepted rules of technology into a surface seal. The same applies to wall bushings for

equipment connections with surface mounted ttings, e.g. showers and bath tubs.

Due to moisture build-up (conden-sation), particular at the cut-out sites in dry lining panelling, e.g. for urinal controls, a seal against

moisture penetration must be applied to building material sur-faces. All other wall penetrations within the dry area (e.g. against the

ceramic facings/tiles) can be sealed with neutrally hardening sanitary silicone.


As for all tap water installations, a pressure test in accordance with DIN 1988-2 is also to be run for the Uponor MLCP system. Before the pressure test, all components of the installation must be freely accessi-ble and visible in order to be able to locate unpressed or incorrectly pressed ttings. All open pipes are to be closed with metal screw plugs, caps, blanking plates or blind anges. Equipment, pressurized tanks or tap water heaters are to be separated from the pipes. It is recommended to perform the pressure test with compressed air or an inert gas if the pipe system is to remain un lled after the test. At the nal inspection the pressure test and ushing must be done with water in accordance with DIN 1988-2.

Pressure test with compressed air or inert gas

The pressure test with compressed air or inert gas is to be run in accordance with the generally accepted rules of technology in two steps, the leak test and the strength test. With both tests, before start-ing the test period, you must wait for temperature equalisation and steady-state condition after pres-sure build-up.

Leak testA visual inspection of all pipe con-nections is to be made before the leak test. The pressure gauge used for the test must have an accuracy of 0.1 bar in the display range for the pressure being measured. The system is pressurised with a test pressure of 110 mbar. For a system volume of up to 100 litres the test period must be at least 30 minutes.

The required time is extended by a further 10 minutes for every addi-tional 100 litres. During the test no leakage may appear at the connec-tors.

Strength testThe strength test is to be run fol-lowing the leak test. Here the pres-sure is raised to a maximum of 3 bar (pipe dimension 63 x 6 mm) or a maximum of 1 bar (pipe dimensions 63 x 6 mm). For a system volume of up to 100 litres the test period must be at least 30 minutes. The required time is extended by a fur-ther 10 minutes for every additional 100 litres.

Pressure testing with water

A visual inspection of all pipe connections is to be made before pressure testing with water. The pressure gauge must be connected at the lowest point of the installa-tion being tested. Only measuring instruments may be used where a pressure difference of 0.1 bar can be read. The installation must be lled with ltered tap water (pro-tect against frost!) and vented. Shut-off valves before and after boilers and tanks are to be closed so that the test pressure is kept away from the rest of the system. The system is to be pressurized with the maximum permissible operating pressure (10 bar) plus 5 bar (in relation to the lowest point of the system). Check the maximum operating pressure with pressure boosting systems! A suitable time must elapse to allow for the tem-perature equalisation between the ambient temperature and the temperature of the ll water. If necessary, the test pressure must be re-established after the waiting period.

Preliminary testRe-establish the test pressure two times within 30 minutes at intervals of 10 minutes. After a further 30 minutes the test pressure must not have dropped by more than 0.6 bar.

Main testThe main test is to be run directly following the preliminary test. The pressure test is considered to have been passed successfully if the test pressure has not dropped by more than 0.2 bar after a further two hours.

After completion of the pressure test all ttings are to be checked for possible leakage. The results of the pressure test must be recorded in a report as a record for the plumber and customer. The forms at the end of this chapter can be used for this report.

Pipe line ushing

The total system is to be ushed thoroughly as soon as possible after installation of the pipes and follow-ing the pressure test. Filtered tap water ( lter in accordance with DIN EN 13443-1) is to be used as ushing liquid. In order to ensure an unlimited operational reliability, ushing must remove all contami-nation and installation residue from the interior surfaces of the pipes and system components, estab-lished the quality of the tap water as well as inhibit corrosion damage and malfunctions of the ttings and components. In general two ush-ing methods can be used:

Flushing with an air water mixture in accordance with DIN 1988-2

This procedure be based on a pul-sating ow of water and air and is described in detail in the Tap water supply systems; materials, compo-nents, appliances, design and instal-lation (DVGW code of practice) DIN 1988-2 section 11.2. Suitable ushing equipment is to be used. This ushing procedure should be used if ushing with water is not expected to produce a suf cient ushing effect.

Flushing with water

If no other ushing method is con-tractually agreed upon or emanded, the Uponor tap water pipelines are to be ushed using the water

method and local supply pressure. The procedure for the pipe line ushing is described in the ZVSHK brochure Notes on ushing meth-ods for tap water installations in accordance with TRWI 1988. This brochure can be obtained from the German Central Association of Plumbing, Heating and Climate-Control System Engineers (ZVSHK), Rathausstrasse 6, 53757 St. Augus-tin. Details and general information on ushing with water can be taken from the brochure. Under point 4.1 the brochure states:The pipes must be ushed as soon as possible after installation. The tap water used for the ushing must be ltered ( lter in accordance with DIN EN 13443-1). In order to pro-tect sensitive ttings (e.g. solenoid valves, ushing valve, thermostats etc.) and equipment (e.g. tap water heater) against damage from ushed foreign matter adaptors should be initially installed in place of such components. Such compo-nents should only be installed after the system has been ushed. Built in ne-meshed sieves installed in front of ttings that cannot be removed or bypassed are to be cleaned after ushing. Aerators, nozzles, ow limiters, shower heads or shower handsets must be removed from the remaining installed ttings during ushing. The manufacturers installation instructions are to be followed for concealed thermostats and other sensitive ttings that cannot be

removed during ushing. All main-tenance ttings, oor shut-off valves and pre-shut-off valves (e.g. angle valves) must be fully opened. Possibly built-in pressure reducers must be fully opened and only be adjusted after ushing.

Depending on the size of the sys-tem and the pipe routing, the installation can be ushed in sec-tions. In this case the ushing direc-tion and sequence should be from the main isolation valve in sections and branches (actual ush section) from the nearest to the furthest branch. One oor after the other is to be ush beginning at the ascend-ing pipe end. Within the story and single supply lines at least as many usage points speci ed as a guideline in the following table for a section being ushed are to be fully opened one after the other for at least 5 minutes. This is to be repeated for each story. Within the story the usage points, beginning with the usage point furthest away from the ascending pipe are to be fully opened. After a ushing period of 5 minutes at the ushing point last opened the usage points are closed one after the other in reverse order.

For the Uponor Unipipe MLC pipe the following guidelines for the minimum number of usage points which are to be opened in relation to the largest inside diameter of the distribution conduit must be observed:

One system for all radiators

The Uponor MLCP radiator con-nection system allows you to install complete heating systems from the heat generator to the furthest radiator fast and economically. The program can be combined without problems with all boilers and radiators offered on the market.

Convince yourself of the variety of the Uponor MLCP system with its components for house or story orientated distribution, control and temperature measurement. Exten-sive accessories round off the assortment.

Radiator connection with the Uponor MLCP system

Variety of connections

The system for connecting radiators is a complete system containing many components. This opens up various connection possibilities. They are suitable for single or double pipe connections and can be quickly and securely connected to all common radiators, whether directly out of the oor or wall. The plus of exibility: You can use any pipe installation method.


Radiator connection set

The Uponor radiator connection set not only facilitates the installation for you. It also protects the pipe against damage in the screed as well as providing for a visually clean spacing guide.

Radiator connection unit

Pressure testing of the system is possible before installing the radia-tors. The preformed Uponor Uni-pipe MLC pipe in the insulation box is simply inserted into the wall and connected with the radiator or the distribution conduits. The radiator can simply be mounted at a later time. The installation of the con-nection is made in the wall. Your bene t: a visually clean connection and installation of the radiator.

Press connection T-piece

With the press connection T-piece you can connect the radiator using coated copper pipes. This ensures a stable construction for everyday use. This variation is used if no wall connection is possible.

Your plus

Practical radiator connection variations for new construction as well as renovation

Absolutely oxygen diffusion tight multi-layer composite pipe

Pre-insulated multi-layer composite pipes and components

Extensive assortment of ttings

Extensive accessory program


The high resilience of Uponor Unipipe MLCP makes it especially suitable for heating installations:

Maximal temperature: 95 C* Maximum continuous operating

pressure: 10 bar at a continuous operation temperature of 70 C, tested hydrostatic stress per-formance of 50 years, safety factor 1.5*

* Please contact the manufacturer if you require additional explanation of the installation parameters.

Fields of application

All heating system components can be connected using the high-quality Uponor Unipipe MLC pipes with an outside diameter of 14-32 mm in coils and 16-110 mm in straight lenghts together with suitable system components such as press and screw ttings. The possibility of supplying over-sized pipe dimensions of up to OD = 110 mm permits their use as cellar distribution and house connection lines in larger heating systems. The Uponor MLCP system can be used from the heat generator over the distribution conduits and house connection lines up to the connec-tion to the heat consumer.

Planning basis for radiator connection

Caution:Uponor Unipipe MLC pipes may not be directly connected to systems with operating temperatures 95 C, such as solar or district heating systems. It must be ensured that the operational limits of the Uponor pipe are not exceeded under any conditions.

With the following methods you can realize trouble-free heating water distribution using the Uponor MLCP system:

Single-pipe heating system Double-pipe heating system Tichelmann system

With a single-pipe heating system all radiators of a heating circuit are connected to a closed ring loop.

In this case ring loops are con-nected directly by a T-piece to the house connection lines of the heat generator. If there are several ring loops, these can be connected to the Uponor heater distributor. The distributor is in turn connected to the house connection line of the heat generator.

As a rule, the adjustment of single-pipe heating systems is usually complex. With a single-pipe heating system the temperature gradient between the radiators, i.e. the decreasing supply temperature from radiator to radiator, must be considered when dimensioning the heating element in the form of an area surcharge.

Bene ts are a result of lower material and assembly costs.

Installation possibilities Single-pipe heating system


The double-pipe heating system with its variations for the single and multi-family dwelling sectors is particularly suitable for low-tem-perature heaters. With this installa-

tion variation the radiators are connected to the supply and return. All radiators have approxi-mately the same supply tempera-ture. A bene t is the fast and easy

adjustment of the double-pipe heating system.

Double-pipe heating system with manifold

With this installation variation the heating water distribution is con-nected to the radiators by means of single inlets from a central mani-fold. The Uponor manifold is in turn connected to the house connection line of the heat generator.

Double-pipe heating system with tee connection and cross tting

Beginning from the house connec-tion line, the heating water distri-bution is made by a common ring loop. If the ring loop runs directly by the radiator, the radiator con-nection can be made with a press connection tee. The last radiator of the ring loop is connected by an Uponor press angle bracket. If the radiator is connected over a single inlet to the ring loop, the use of a cross tting is recommended.

Tichelmann system

In the Tichelmann system the pipes are arranged in such a way that the sum of the length of supply and

return for each radiator is approxi-mate equal. That means that the radiator with the longest supply has

the shortest return. Thus a more uniform pressure drop in the individual stages is achieved.

Pressure testing for the radiator installation

Pressure test for radiator installation in accordance with DIN 18380

The following procedure describes the pressure test for the Uponor MLCP system with screw or press connections.

The heating engineer/plumber has to perform a leak test on the heater pipes after installation and before closing wall slits, wall and oor breakthroughs as well as, if neces-sary, before the screed or other covering is laid.

The heating system is to be lled slowly and completely vented (protect against frost!). This can be done quickly and with little effort with the Uponor pressure test plug. Water heaters are to be checked with a pressure of 1.3 x the total

pressure (static pressure) of the system; however, at least 1 bar excess pressure must be reached throughout the system. Only pressure meters may be used that permit the accurate reading of a 0.1 bar pressure change. The pressure meter is to be connected, if possible, to the lowest point of the system.

After the test pressure has been reached a suitable time must elapse to allow for temperature equalisa-tion between the ambient tempera-ture and the temperature of the ll water. If necessary, the test pres-sure must be re-established after the waiting period.

The test pressure must be main-tained for 2 hours and may not drop by more than 0.2 bar. No leakages may appear during this time. As soon as possible after the cold water pressure test the system is heated to the highest calculated heating water temperature to check whether the system also remains leak-free at high temperature. After the system cools down the heating pipes and connections are to be checked for leaks.
