Only pipe clamps with chloride-free sound insulating inlays should beused to secure the pipes.

Observe the general rules of fixing technology:

n Do not use fixed pipelines as a support for other pipelines and com‐ponents.

n Do not use pipe hooks.n Observe distance to connectors.n Observe the expansion direction: Plan fixed and gliding points.

Make sure to affix the pipelines in such a way as to de-couple themfrom the installation body, so that they cannot transfer any structure-borne sound, resulting from thermal expansion or possible pressuresurges, onto the installation body or other components.

Observe the following fixing intervals:

Pipelines expand with heat. Heat expansion is dependent on the mate‐rial. Changes in length lead to tension within the installation. These ten‐sions must be equalised with suitable measures.

The following are effective:

n Fixed and gliding pointsn Expansion equalisation joints (expansion bends)

Heat expansion co-efficients of various pipe materials

Material Heat expansion co-effi‐cient ⍺ [mm/mK]

Length expansion withpipe lengths L = 20 m

and ΔT = 50 K [mm]

Raxofix-PE-Xc 0.17 170

Calculation example PE-Xc pipe:

n Given: Temperature difference Δϑ = 50 K; Pipe length L = 8 m;Pipe ⌀ = 20 mm

n Required: Expansion bend length LBS

n Calculation:– Beginning in the left-hand diagram: From 50 K temperature dif‐

ference on the x-axis up to the characteristic line for the 8 mpipe length.

– Connect the intersection horizontally with the right-hand dia‐gram up to the intersection of the characteristic line for pipediameter 20 mm.

n Result: Read the value from the x-axis: LBS = 430 mm.

2.3.3 Press connectorsPress connectors are available in a number of shapes. An overview ofthe press connectors suitable for the system can be found in the cata‐logue.

Fig. 4: SC-Contur

Viega press connectors are equipped with the SC-Contur. The SC-Contur is a safety technology that is certified by the DVGW and ensuresthat the connector is guaranteed to be leaky in an unpressed state. Inthis way, inadvertently unpressed connections are noticed immediatelywhen filling the system.

Viega ensures that inadvertently unpressed connections during installa‐tion become visible when the system is filled.

n with wet leakage test in the pressure range from 0.1–0.65 MPa (1.0–6.5 bar)

n with dry leakage test in the pressure range from 22 hPa–0.3 MPa(22 mbar–3.0 bar)

2.3.4 Markings on components

The pipe markings contain important information regarding the qualityand certification of the pipes. Their meaning is as follows:

n manufacturern System namen pipe materialn size / wall thicknessn certification and operating temperatures

Fig. 5: Marking

The green dot shows that the press connector is equipped with theSC-Contur and that the system is suitable for drinking water.

2.3.5 Mixed installationsAll Raxofix pipes may only be mounted using original accessories, Rax‐ofix connectors with SC-Contur and the corresponding press tools. Usewith components of other plastic piping systems, such as e. g. SanfixFosta, is not permitted.

Please contact the Viega Service Center for questions on this subject.

2.4 Information for use2.4.1 Chemical resistance

NOTICE! Damage to material due to aggressive chemicalsAggressive chemicals, especially those containing solvents,may cause material damage and leaks. This may lead towater damage.

– Prevent contact between the system components andaggressive chemicals.

For storage, comply with the requirements specified in the applicableregulations, see Ä „Regulations from section: Storage“ on page 7:

n Store rods on even, clean surfaces.

3.2 Assembly information3.2.1 Mounting instructions

NOTICE! Material damage due to thread locker containing solvents!Thread lockers containing solvents can lead to materialdamage and leaks in plastic parts of pipe connections. Thismay lead to water damage.

– As a sealant, only use commercially available hemptogether with thread sealing paste or certified sealingtape for potable water.

– Please contact the Viega Service Center if you have anyquestions.

System components may, in some cases, become damaged throughtransportation and storage.
