Assembly information
Mounting conditions
Suitable walls
The Viega WC element is suitable for mounting on masonry wall constructions and support profiles pursuant to the regulations in section Regulations from section: Fields of application / Mounting conditions .
The WC element may only be mounted on even wall surfaces.
Construction height
With the construction height, the marked height of the upper edge of the finished floor must be observed.
INFO!
Errors caused by incorrect construction heights may limit the setting range after the completion of the work. A correction and therefore a limitation of the setting range is only possible up to max. 20 mm. The setting range is reduced accordingly from 80 mm to 60 mm.
Installation depth
The installation depth is 200 mm.
WC ceramic
The WC element can only be used in combination with wall-hung WCs (fixing gauges for bore hole 180 mm).
On request, wall-hung WCs with a fixing gauge for bore holes of 230 mm may be used.
Actuation
The WC element can be extended by a remote actuation Visign for Public1 (model 8326.21) or by an electronic actuation (model 8350.31 or 8350.32). The corresponding actuation method must be prepared before the WC element is clad and tiled.
The corresponding empty pipe (included in the scope of delivery of the remote actuation) is required when preparing the remote actuation Visign for Public1.

Limiting the setting range
The length of the gas pressure spring, and therefore also the setting range of the WC, can be limited by max. 20 mm if the upper edge of the finished floor is higher than intended.
The cover plate can be prevented from touching by using spacer washers (4 mm each).
A maximum of five spacer washers may be used.
Requirements:
WC ceramic is at the lowest position
Following components are removed:
WC ceramic
Cover plate
Actuating button / hydraulic actuation
Cover frame
-
Remove gas pressure spring by lowering the top and bottom 5 mm Allen screw.
-
Place the relevant number of spacer washers below the piston rod of the gas pressure spring.
Attaching protective sticker
Depending on the version of the WC lid, it may be that there is contact with the wall during the height adjustment of the WC. Attaching the protective sticker prevents damage to the surface in the possible contact area on the wall and on the WC lid.
-
Determine possible area of contact between the wall and the WC lid on the wall.
-
Clean possible contact area on the wall.
-
Remove the protective foil from the protective sticker and attach in the possible contact area.
INFO!
The protective sticker should remain on the wall to protect the wall and the WC lid from damage to the surface in the case of further height adjustments.
Preparing mounting for required accessories
Mounting the connection set for WC ceramic
-
Adapt the length of the flushing pipe and drainpipe.
-
Cut the sound insulation panel to size.
-

Use
CAUTION!
Risk of crushing
The cover plate shifts in parallel with the wall surface during the height adjustment. Due to this, there is the risk of crushing in the areas above and below the cover plate.
Keep hands and feet away from the dangerous areas.
Lowering WC
Requirements:
Total weight of min. 60 kg (body weight and WC ceramic)
WC ceramic's own weight max. 28 kg
open WC lid

Cleaning and maintenance
Maintenance and cleaning work may only be carried out by specialist trade professionals or qualified experts.
Cleaning
The cover plate may only be cleaned using mild cleaning agents containing soap.
Scouring milk and cleaning agents or disinfectants containing the following ingredients may not be used:
alcohol
ammoniac
hydrochloric acid
phosphoric acid
acetic acid
NOTICE!
Pipe damage
Do not use a cleaning spiral around the area of the flexible drain elbow on the WC connection.
Maintenance
The mechanism of the WC element is maintenance-free.
Cleaning and maintenance of the concealed cistern
In consideration of the mechanical, chemical and physical conditions, the concealed cistern is constantly laden.
For this reason, the components must be cleaned, as required, and the drain and filling valve seals renewed.
In areas or regions with hard water due to calcium or magnesium salts, there is the risk of limescale deposits developing on the inlet and drain valves.
The valves may have to be replaced, depending on the extent of deposits.
Disposal
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.
