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
Industrial units
The model serves as a shut-off for the storey units.
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 Easytop system fittings comply with the test requirements specified in the applicable regulations, see Regulations from section: Overview Sound protection Lap≤ 20 dB(A)
The model is equipped as follows:
valve casing and top made of gunmetal/silicon bronze
Site protection
dual-sided press connection with SC‑Contur
sealing elements made of EPDM
green dot for potable water
The model is available in the following dimensions: d 15 / 18 / 22.
The press connection has a circumferential bead in which the sealing element lies. The connector is deformed upstream and downstream of the bead and permanently connected to the pipe during pressing. The sealing element is not deformed during pressing.
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 wet leakage test in the pressure range from 0.1 hPa–0.65 MPa (1.0 mbar–6.5 bar)
with dry leakage test in the pressure range from 22 hPa–0.3 MPa (22 mbar–3.0 bar)
Only EPDM sealing elements are approved in potable water installations. The use of other sealing elements is not permitted.
The model is factory-fitted with EPDM sealing elements.

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:
Insulating shell
Equipment sets
Public building model
Mounting sets
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.
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.
Observe the following when mounting:
minimum / maximum installation depth
use suitable tools
Choose the place of installation so that the fitting is easily accessible, simple to operate and the insulating shell can be well mounted.
For information, refer to the instructions for use of the Profipress, Sanpress and Sanpress Inox systems.
For information, refer to the instructions for use of the Profipress, Sanpress and Sanpress Inox systems.
The following tools are required for production of a press connection:
pipe cutter or a fine-toothed hacksaw
deburrer and coloured pen for marking
press machine with constant pressing force
Press jaw or press ring with corresponding hinged adapter jaw, suitable for the pipe diameter and suitable profile
Recommended Viega press machines:
Pressgun 5
Pressgun Picco
Pressgun 4E / 4B
Picco
Type PT3-AH
Type PT3-H / EH
Type 2 (PT2)
Do not use pointed or sharp-edged objects to remove the sealing element. These could damage the sealing element or bead.
Remove the sealing element from the bead.
Insert a new, undamaged sealing element into the bead.
Ensure that the complete sealing element is in the bead.
Leaky press connections due to damaged material!
Press connections can become leaky due to damaged pipes or sealing elements.
Observe the following instructions to avoid damage to pipes and sealing elements:
Do not use cutting discs (angle grinders) or flame cutters when cutting to length.
Do not use grease or oils (e. g. cutting oil).
For information about tools, also see Required tools .
Cut the pipe properly using a pipe cutter or fine-toothed hacksaw.
Avoid grooves on the pipe surface.
Leaky press connections due to pipes being too short
If two press connectors are to be mounted onto a pipe without an interval, the pipe must not be too short. If the pipe is not inserted up to the prescribed insertion depth in the press connector during pressing, the connection may become leaky.
With pipes with a diameter of d 15–28 mm, the length of the pipe must be at least as long as the total insertion depth of both press connectors.
Requirements:
The pipe end is not bent or damaged.
The pipe is deburred.
The correct sealing element is in the press connector.
EPDM = polished black
The sealing element is undamaged.
The complete sealing element is in the bead.
Push the press connector onto the pipe as far as it will go.
Mark the insertion depth.
Place the press jaw onto the press machine and push the retaining bolt in until it clicks into place.
Observe the press tool instruction manual.
Open the press jaw and place at a right-angle onto the connector.
Check the insertion depth using the marking.
Ensure that the press jaw is placed centrally on the bead of the press connector.
Carry out the pressing process.
Open and remove the press jaw.
Connection is pressed.
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 fitting from behind with the fixing set onto a Viega fitting holder with slot nuts.
Seal the wall lead-in on the front side of the wall with the self-adhesive sealing flange.
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 with a ¼ turn.
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.
