The information about the products, their properties and application technology are based on the current standards in Europe (e. g. EN) and/or in Germany (e. g. DIN/DVGW).
Some passages in the text may refer to technical codes in Europe/Germany. These should serve as recommendations in the absence of corresponding national regulations. The pertinent national laws, standards, regulations and guidelines, as well as other technical guidelines, have priority over German/European guidelines in this manual: The information is not binding for other countries and territories and should, as mentioned, be considered as support.
Intended use
INFO!
The use of the system for areas of use and media other than those described must be approved by the Viega Service Center.
Areas of use
The Smartloop Inliner technology is employed as an internal circulation pipe in drinking water installations. The system is particularly suitable for hot water riser pipes from d 28 and above.
The general rules of engineering must be observed for planning, execution, operation and maintenance of drinking water installations.
e. g. the following regulations apply:
DIN EN 806 Part 1–5 and DIN EN 1717
Supplementary national regulations amongst others DIN 1988, VDI/DVGW 6023 and Drinking Water Ordinance (DWO)
DVGW Worksheet W 553
We recommend using the planning software Viega Viptool when laying a drinking water installation with Smartloop Inliner technology.
Media
The system is suitable for the following media:
Drinking water
without restrictions in acc. with DWO
max. chloride concentration 250 mg / l (in acc. with DWO)
Product description
In acc. with DWO and DIN 50930‑6, Smartloop Inliner technology is suitable for use with all types of drinking water. The plastic components conform with the KTW recommendation and the requirements of DVGW Worksheet W 270.
Overview
The Smartloop system consists of the following components:
Smartloop connection set (model 2276.1)
Smartloop pipe (model 2007.3)
Smartloop tension coupling (model 2276.9)
Smartloop repair coupling (model 2276.8)
- 1 - end closing piece
- 2 - press sleeve
- 3 - adapter
- 4 - connecting piece
- 5 - press sleeve
- 1 - support sleeve
- 2 - tension head
- 1 - press sleeve
- 2 - repair nipple
- 3 - press sleeve
The system components are available in the following dimensions:
end closing piece-/connection piece d = 28, 35, 28 / 35
Smartloop pipe d = 12
Operating mode
- 1 - end closing piece
- 2 - floor connection line hot water
- 3 - internally positioned circulation pipe
- 4 - hot water riser pipe
- 5 - hot water supply pipe
- 6 - connecting piece
- 7 - circulation collector line
- A–F - Ground to 5th floor
The circulation of hot water in the line is achieved in the following way: Water is directed back into the hot water heating system and replaced by hot water via the opening in the end closing piece (1) of the last T-piece (2). This ensures that sufficient hot water is available at hygienically flawless temperatures at every floor connection line.
The temperature in the riser pipe area does not continually drop in the direction of flow with Smartloop Inliner circulation. The lowest temperature in the riser pipe is therefore at the end closing piece, in the area of the diversion in the internal circulation. With large-scale systems with several lines, this leads to an increase in the temperature in the circulation collector pipe. As a result, the temperature of the return flow water is higher than with conventional circulation systems, which, in turn, has advantages in terms of energy.
Press connection with SC-Contur
The press connection has a circumferential bead in which the sealing element lies. The connector is deformed in front of and behind the bead and permanently connected to the pipe during pressing. The sealing element is not deformed during pressing.
SC‑Contur
Viega press connections are equipped with the SC‑Contur. The SC‑Contur is a safety technology that is certified by the DVGW and ensures that the connection is guaranteed to be leaky in an unpressed state. In this way, unpressed connections are noticed immediately during a leakage test.
Viega guarantees that unpressed connections are visible during a leakage test:
with the wet leakage test in the pressure range from 0.1–0,65 MPa (1.0–6.5 bar)
with dry leakage test in the pressure range from 22 hPa–0.3 MPa (22 mbar–3.0 bar)
Sealing elements
Area of use of the EPDM sealing element
NOTICE!
Only EPDM sealing elements are approved in drinking water installations. The use of other sealing elements is not permitted.
The model is factory-fitted with EPDM sealing elements.

Information for use
Permitted mixed installations
Generally, components from different piping systems should not be used in the same installation. The different materials may have a detrimental effect on each other e. g. cause corrosion.
Generally, components from the Viega systems Profipress, Sanpress and Sanpress Inox can be used in the Smartloop system.
INFO!
The flow rules must be observed in all mixed installations with different metals.
Should you have any questions on this subject, please contact the Viega Service Center.
Corrosion
Overground pipelines and fittings in rooms do not normally require external corrosion protection.
There are exceptions in the following cases:
Contact with aggressive building materials such as nitrite or materials containing ammonium
in aggressive surroundings
If external corrosion protection is required, the following regulations should be followed:
DIN EN 806‑2
DIN 1988‑200
DKI information publication i. 160
INFO!
The chloride concentration in the medium must not exceed 250 mg/l.
This chloride is not a disinfectant, but in fact pertains to the content in sea and table salt (sodium chloride).
Handling
Assembly information
Permitted exchange of sealing elements
INFO!
Important instruction
With their material-specific qualities, sealing elements in press connectors are adapted for use with the corresponding media and/or the areas of use of the piping systems and are generally only certified for them.
The exchange of a sealing element is generally permitted. The sealing element must be exchanged for a designated spare part for the intended application Sealing elements . The use of other sealing elements is not permitted.
