Intended use

Areas of use

The drain is designed for small to medium volumes of water, which occur in e. g. residential building.

Technical information, see Ä Chapter 2.3.2 „Technical data“ on page 9.

The drain with vertical drain socket is suitable for installation in drill holes and can be used in low floor construction heights from 20 mm to 105 mm.

The water seal level of 30 mm and the small drainage capacity do not meet the specifications pursuant to the standards and regulations. See Ä „Regulations from section: Fields of application“ on page 6.

Check if the drainage capacity is sufficient before mounting!

Media

The drain is intended for draining of household-type wastewater in con‐
stant operation, see Ä „Regulations from section: Media“.

• The short-term temperature of the wastewater may reach up to 95° C. The temperature must be considerably lower in constant operation.
• The pH value must be higher than 4 but lower than 10.

It is not permitted to introduce wastewater which would damage the product material.

Operating mode

Odour trap

In most drains, the ingression of sewer gases into rooms with drains is prevented by an odour trap with a water seal. If the drain has not been used for a long time, the water seal can evaporate and this may lead to odour nuisance.

Fig. 1: Mode of operation of the odour trap

The odour proof odour trap prevents the ingression of sewer gases,
even after the water seal has evaporated. The odour proof odour trap is
equipped with two shutter valves, as can be seen in the lower part of
the graphic. If the water seal has evaporated, the shutter valves close
and hold the sewer gases back in the drain.

Information for use

Installation variations

Installing in a bare concrete floor

The mounting of the drain in a bare concrete floor is as follows:

The drain is placed over a floor lead-in (e. g. of a drill hole), through which the drainpipe is led.

Fig. 2: General mounting example – Drill hole

NOTICE!
The creation of a floor recess must be agreed with the fol‐ lowing people:

• a structural engineer
• the on-site fire protection inspector or the specialist engineer for fire protection

If necessary, proof of compliance with building code or an expert’s report must exist.

Sealing

The drain can be sealed both conventionally as well as with bonded sealing.
Depending on the type of sealing, you will require the relevant equip‐ ment set  Chapter 2.5 „Required accessories“.

Conventional sealing

The flange of the drain is intended for conventional sealing. To be able to seal the drain conventionally, you require a suitable sealing collar and a clamping ring with which the cuff is secured Ä Chapter 2.5 „Required accessories“.

Fig. 3: Construction diagram of a conventional sealing

NOTICE!
Not suitable for floor-level showers
Conventional sealing is not recommended with floor-level showers, because dampness can enter the screed and damp proof layer.
The bonded sealing should be used in the case of floorlevel showers.

Principle

Traditionally, sealing is made using bitumen or EPDM sealing collars.
The sealing collars are laid directly onto the raw concrete or heat insula‐ tion. This process has proved itself to be particularly effective for sealing balconies, patios, floor installation panels and cellar floors. In addition, sealing collars are often used as an additional second sealing layer below the bonded seal.

The following components are required for the installation of a drain with conventional sealing:

• Drain
• Clamping ring with sealing collar for EPDM and bitumen sealing lanes

Information for processing

The sealing collar is coated with EPDM on the one side and with bitumen on the other side

Place the sealing collar on the drain and fasten it with the flange. It depends on the sealing collar used which material layer of the sealing collar is placed facing up. You can find more information in the mounting instructions of the sealing flange.

Bonded sealing

To protect against moisture penetration, apply sealing foils, which are to be processed in liquid state, directly below the tiles on screed and walls. The determination of the stress class and the underground as well as the selection of the suitable bonded sealing must be carried out in compliance with the valid standards and regulations, see: Ä „Regula‐ tions from section: Sealing“ on page 6.

Bonded sealing can be carried out with the help of a suitable stacking element. You have the possibility to double seal, using conventional and bonded sealing or only using bonded sealing

Fig. 4: Diagram of a bonded seal

Important note

Careful planning is required for professional sealing. In addition, depending on the individual dampness wear class and the type of foun‐ dation, a suitable BS system with a building regulations certificate of suitability must be chosen.

Furthermore, the following factors should be taken into account:

• Drain or shower channel must be equipped with a special flange, which has an adhesive surface and a width of at least 30 mm.
• For bridging the material change from drain to screed, either a suit‐able sealing collar or sealing tape designed for overlapping with the BS over a width of at least 50 mm must be used.
• The screed must be laid at a minimum incline of 1–2 %.
• The installation must be carried out properly in acc. with the mounting instructions and the manufacturer’s information.

You will find a corresponding set in the catalogue (model 4948.31).

Accessories for the bonded sealing

If a bonded sealing is to be applied, a suitable stacking element with sealing collar is required.
You will find a corresponding set in the catalogue (model 4925).

Handling

Assembly information

Important note

Before assembly:

• Check if the drainage capacity of the drain is sufficient for the arising water volume Ä Chapter 2.2.3 „Drainage capacity“ on page 7.
• Check if the installation height of the drain corresponds with the planned floor construction.
• Ensure that the required connection line is installed with the neces‐ sary incline to the planned installation location.
• If necessary, supply the required accessories Ä Chapter 2.5 „Required accessories“ on page 14.

During assembly:

• Observe installation dimensions.
• Decide whether or not a backflow seal is required in the insertionpart of the top.

After assembly:
The drain flange must be fully lined with mortar.

Tools and materials

Required material

• if necessary, sealing collar, clamping ring, fitting screws
• Top with grate, if not included in scope of delivery Ä Chapter 2.3.1 „Overview“.
• if necessary, stacking element for bonded sealing model 4925
• Material for securing the drain

Assembly

Connecting the drain

Connecting to the wastewater system

The connection to the wastewater system must be completed before the drain can be installed in the floor construction. Proceed as follows: Requirements:

• A pipe to the planned drainage position is already in place for the connection to the wastewater system.
• The drainpipe has an internal sealing lip. Push the drain socket into the drainpipe completely.

Prepare for subsequent work

A few points must be observed to integrate the drain into the floor con‐ struction properly. For this reason, proceed as follows to prepare the drain for subsequent work:

Requirements:

• The drain is connected.

• Position the drain at the desired height at the place of use.
  Depending on planning, the drain can be integrated into concrete, screed or a heat insulation layer, for example. It is important that the upper edge of the drain flange is flush with the upper edge of the sealing layer. If necessary, raise or lower the drain in the existing floor using suitable material.

• Align drain horizontally using a spirit level.

• Secure the drain in such a way that it cannot shift when the subse‐ quent works are applied.
  Most importantly, it must be ensured that the drain does not float when the concrete or screed is poured in.

• Insert yellow protective plugs.

NOTICE!
Product damage due to improper installation
If hollow spaces occur during the lining of the drain, leaks may occur when pressure is applied.

Inform the subsequent workers that the drain must be fully lined and that there must be no hollow spaces.

Sealing the drain

NOTICE!
Product damage due to improper installation
If hollow spaces occur during the lining of the drain, leaks may occur when pressure is applied.

Check the proper completion of the subsequent work.

Screed and floor tiles must be laid at an incline of 1–2 % in the direction of the drain.

Conventional sealing

Requirements:

• A suitable sealing collar and a clamping ring are available.

• The flange is free of heavy soil.

• The complete surface of the flange is lined with material and undam‐ aged.
  If required, clean the flange of coarse soil (e. g. from screed).

• Insert sealing ring.
  The sealing ring must lie in the groove between the flange and the screw holes.

INFO! The Viega sealing collar has two differently coated sides. One side is coated with bitumen and the other side with EPDM. If the additional sealing takes place with bitumen sealing lanes, the sealing collar must be used with the bitumen side facing upwards. If EPDM sealing lanes are used, the EPDM side must face upwards.

Position the sealing collar on the drain.
The screw holes must be visible through the recesses.

Position the sealing flange on the sealing collar in such a way that the screw holes are visible.

Screw the sealing flange together tightly with the drain.
The fixing screws of the clamping ring may only be screwed into the screw holes of the drain.
The drain is sealed and the remaining sealing collars can be laid.

Bonded sealing

Requirements:

• The flange is free of heavy soil.
• The complete surface of the flange is lined with material and undam‐ aged.
  Remove protective foil.

Apply the bonded sealing on the dry screed and spread to the inner edge of the flange fleece.
NOTICE! Observe the bonded sealing manufacturer’s instructions for use.

Lay the sealing collar into the bonded sealing.

Apply a second layer of bonded sealing onto the sealing collar and, if necessary, onto the floor.

Mounting the top

The top with the grate must still be mounted to finish off the mounting of the drain. Proceed as follows:

• Calculate the height of the floor construction from the edge in the inside of the drain up to the upper edge of the tiles.
  

• Starting with the upper edge, transfer the measured height onto the top.

• Cut the top to the marked height.

• If necessary, insert backflow seal in the lowest notch of the top.
  INFO! The backflow seal be must employed when no damp‐ ness is supposed to flow into the drain from outside of the top but water may seep in from below. Normally, no backflow seal is mounted so that water that occurs around the frame (e. g. due to a leaky silicone joint) can flow away. A backflow seal is mounted in the following cases:

  • In the case of the risk of a build-up of water that can soak through the screed.
  • During the mounting of a stacking element for the bonded sealing (see instructions for use of the stacking element).
    

• Remove yellow protective plug.
  

• Place the top into the drain and align according to the tiles.

• Work the top into the screed or the floor covering.

Care

Care tips

Normal soap or a mild cleaning agent can be used for regular care and prevention of lime scale on the grate and frame. Under no circum‐ stances should scouring agent or scratching objects be used.

Strong stains, even around the drain unit and the siphon, can be removed using typical household cleaner. It should be noted that the cleaning agent should be rinsed off after the prescribed soaking time.
There should be no residue on the components.

Cleaning the drain

We recommend using a mild cleaning agent and a washing-up brush for cleaning.

• Remove and clean grate
  

• Remove and clean odour trap.
  

• Remove and clean odour trap.
  

• Clean drain.
  

• Replace odour trap.

• Re-insert grate.

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.
