Coordinate the use of the model for areas of use and media other than those described with the Viega Service Center.
Use is possible in the following areas among others:
Drinking water installations
The model serves as a shut-off for the storey units.
It provides the possibility to attach a Koax G 2 measuring capsule.
The general rules of engineering and the applicable regulations must be observed for planning, execution, operation and maintenance potable water installations, see Regulations from section: Fields of application .
The model is also suitable for the following media, amongst others:
Drinking water without limitations acc. to the applicable directives, see Regulations from section: Media
maximum chloride concentration 250 mg/l pursuant to applicable regulations, see Regulations from section: Media
According to the applicable regulations, Easytop system fittings can be used for all types of potable water and are DVGW certified, see Regulations from section: Product description . Their plastic components comply with the KTW recommendation and the requirements pursuant to the applicable regulations.
The model is equipped as follows:
Site protection
valve casing made of gunmetal/silicon bronze
valve seat made of stainless steel
dual-sided Rp-thread
two concealed straight seat valves
recess for two Coax measuring capsules G 2
two blind flanges
mounting set
insulating box (sound and heat insulation)
The model is available in the following dimension: Rp ¾.
Prerequisite for a threaded connection, which seals via a thread, is a threaded pair in accordance with applicable regulations, see Regulations from section: Threaded connection . Pursuant to these regulations, a permitted threaded pair comprises a conical external thread and a cylindrical internal thread, e.g. R ¾ and Rp ¾.
Only use commercially available and chloride-free, DVGW approved sealant in accordance with the applicable regulations to seal threads, see Regulations from section: Threaded connection .
The model is marked as follows:
flow direction indicator
dimension
DVGW writing
position indicator
Observe the manufacturer's instructions for mounting and use.
Should you have any questions on this subject, please contact the Viega Service Center.
Observe the following operating conditions for the installation of the model:

Operating pressure [Pmax] |
90 °C |
1.0 MPa (10 bar) |
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, observe the pertinent guidelines, see Regulations from section: Corrosion .
Easytop fittings made of gunmetal/silicon bronze are suitable for all types of potable water.
The chloride concentration in the medium must not exceed a maximum value of 250 mg/l.
This chloride is not a disinfectant, but in fact pertains to the content in sea and table salt (sodium chloride).
The following optional accessories are available:
Equipment sets
Public building model
mounting set
Do not remove the model from the packaging until immediately before use.
System components may, in some cases, become damaged through transportation and storage.
Check all parts.
Replace damaged components.
Do not repair damaged components.
Contaminated components may not be installed.
A blind flange ensures unhindered operation until assembly is completed.
Observe the following when mounting:
flow direction indicator
minimum / maximum installation depth
use suitable tools
Choose the place of installation so that the fitting is easily accessible and simple to operate.
Carry out a functionality test after initial mounting.
Installation is possible in masonry (wet construction) and in dry constructions (pre-wall / duct installations).
Attach the protective sleeve of the valve in front of and behind the cladding (e. g. sheetrock or Fermacell panels) with lock nuts.
Seal the wall lead-in on the front side of the wall with the self-adhesive sealing flange.
Open or close the valve clockwise or anti-clockwise respectively.
During the preliminary building work phases:
Actuate the valve via the protective cap.
The installer must perform a leakage test before commissioning.
Carry out this test on a system that is finished but not yet covered.
Comply with the general rules of engineering and the applicable directives, see Regulations from section: Leakage test .
Document the result.
Inform your customer or the operator of the drinking water installation that the system has to be maintained on a regular basis.
Observe the applicable regulations for the operation and maintenance of drinking water installations, see Regulations from section: Maintenance .
Viega recommends actuating the fitting regularly and checking its function.
Separate the product and packaging materials (e. g. paper, metal, plastic or non-ferrous metals) and dispose of in accordance with valid national legal requirements.
