2. Fit the rubber sleeves for pipe lead-through as shown in the provided diagram and clamp them.
3. Check that the knockout holes are fully open.

Installation of the box in the wall

1. Choose the desired position for installing the box in the wall.
2. Follow the provided diagrams to install the box properly, ensuring that it is securely fixed in place.

Pipe routing in the wall

1. The box is designed for PEX pipes with an outer diameter of 15 or 16 mm and conduit pipe with an outer diameter of 25 mm.
2. Route the pipes in the wall according to the instructions provided by the pipe manufacturer.
3. Clamp the pipes securely.

Leakage indication Use the PEX pipe’s conduit with a minimum inside diameter of 20 mm to drain any leakage water from the box.

1. Fit the rubber sleeve for pipe lead-through into the box upon delivery.
2. Connect the pipe to the rubber sleeve and run it out through the wall, outside the position of the shower and bathtub. 4. Cut the pipe 2 mm outside the finished wall. 5. Use
   Tapwell’s leakage indication disc to conceal the pipe opening.

Fitting the box cover

1. Fit the cover before starting the work on waterproofing.
2. Check that the sealing rings are correctly positioned in the groove on the cover.
3. Press down the cover into the box so that the cover flange lies against the wall board. 4. Screw the cover in position by tightening the four enclosed screws crosswise.
   Note: Please refer to the complete user manual for detailed instructions on other chapters, including waterproof membrane installation,connecting the mixer to the box, and leakage testing.

  The product has been verified as per NT VVS 129 and ETAG 022, Annex F.

UNPACKING

Technical conditions for installation

Installation of the box requires a clearance of at least 68 mm in the wall. The combined thickness of the wall boards as shown in 1-1 may be max. 36 mm and min. 24 mm.

Preparation of the box before installation in the wall
Remove the box’s knockouts for incoming water using a hammer and a suitable punch, as shown in 2-1. The rubber sleeves for pipe lead-through are fitted as shown in 2-2 and clamped.

Check that the knockout holes are fully open.

Installation of the box in the wall

A 265×265 mm hole should be made in the wall boards for the box. The vertical and horizontal position of the box should be decided in consultation with the client and with any support for the wall studs. The box can be screwed to the underlying wall as shown in 3-1 using the four enclosed screws and seals. Installation requires a clearance of at least 65 mm and a wall board that can take screws. For 70 mm wall studs use nogging pieces of 2 mm thick board, for 95 mm studs use nogging pieces of 27 mm thick board, see 3-2.
Alternatively, the box can be installed on wall studs with the help of mounting rails, as shown in 3-3, where the lower rail is screwed level on the wall. The box is then placed on the rail, as in 3-4, and the upper rail is placed over the box’s flange and screwed to the stud, as in 3-5. The slots in the rail are then deformed as shown in 3-6 so that the box is secured sideways.
The rails are not supplied with the box as the screw alternative is the most common option. The rails must be ordered separately, stating the c/c spacing of the studs. Rails are available for 600 and 450 mm c/c spacing between the studs.

Pipe routing in the wall

The box is designed for PEX pipes of o.d. 15 or 16 mm, with conduit pipe of o.d. 25 mm. The pipes are to be routed in the wall and clamped according to the instructions provided by the pipe manufacturer. The couplings required to connect the mixer’s flexible pipes, as shown in 4-1, depend on the type of pipe and its dimensions, and are not supplied with the box.

Leakage indication

The PEX pipe’s conduit with an inside diameter of min. 20 mm can be used to drain any leakage water from the box. The rubber sleeve for pipe lead-through into the box is fitted in the box on delivery.
The pipe is connected to the rubber sleeve and should run out through the wall, as shown in 5-1, outside the position of the shower and bath tub and be cut 2 mm outside the finished wall, as in 5-2.
Universal shears RSK 1875674 are recommended for cutting.
Tapwell’s leakage indication disc can be used to conceal the pipe opening, as shown in 5-3.

Fitting the box cover
The cover needs to be fitted before starting the work on waterproofing. Check that the sealing rings are correctly positioned in the groove on the cover, as in 6-1.

The position of both sealing rings must be checked with regard to the correct placement in the groove on the cover.

The cover is pressed down into the box so that the cover flange lies against the wall board.
The cover is screwed in position by tightening the four enclosed screws crosswise, as shown in 6-2.

Waterproof membrane

• Fit the waterproof membrane to the cover of the box. Note that the waterproof membrane should end approx. 4 cm from the opening in the box cover, as shown in 7-1. This applies to both foil and rolled systems.
• The waterproof membrane must have industry approval from the Swedish Ceramic Tile Council and be tested and approved as per ETAG 022, meeting the vapour resistance requirement at a ratio of RH 75%:100%. The waterproof membrane must also be approved as per ETAG 022, Annex F regarding the membrane’s maximum adhesion to the box cover.
• The brands and types of waterproof membrane approved to date for use with the T-Box 2.0 Small are:
• LIP foil membrane system, LIP liquid membrane system, Alfix liquid membrane system, Ardex foil membrane system,
• Weber foil membrane system no. 2, Weber liquid membrane system, Sopro foil membrane system no. 1, Sopro foil membrane system no. 2, Sopro liquid membrane system, Mira foil membrane system, Mira liquid membrane system, Kiilto liquid membrane system.
• For the most current list of approved waterproof membranes, see Tapwell’s website.
• The box cover comes with a corrugated surface for maximum adhesion between the waterproof membrane and the cover.
• The corrugated surface needs to be cleaned with a cleaning agent recommended by the membrane manufacturer prior to the installation of the membrane.
• The responsibility for installing the membrane according to this instruction and in the manner and with the materials specified in the approval lies with the waterproof membrane contractor.

Connecting the mixer to the box

The supplied flexible connection pipes are screwed to the mixer all the way to stop by hand, see 8-1.

• Red pipe for hot water, blue for the cold water.
• The mixer’s flexible pipes are connected to the property’s hot and cold water supply as shown in 8-2.
• The flexible hoses are fitted with captive nuts for flat seals, dim. ½”.
• The mixer is then fitted in position and screwed to the box cover as shown in 8-3. The 4 screws should be tightened crosswise until the rubber seal fills any irregularities in the surface of the wall.

Check that no folds occur in the flexible connection pipes when they are being moved back through the opening.

Leakage testing

• Leakage test the mixer installation in existing assemblies at the system’s operating pressure.
• Leakage testing in new builds must be performed according to the instructions in the object’s technical description.
• Testing is performed using water of drinking water quality and is to be documented.
• A leak test may be performed at a maximum water temperature of 70°C and maximum test pressure of 10 kPa.
