CAROMA CONTURA II- WALL BASIN/BATH MIXER TRIM KIT

PLUMBERS INSTALLATION INSTRUCTIONS

WATER EFFICIENT TAPWARE

Important Information

Trim kit (parts 1-7 & 13-18) and body kit (parts 8-12) are supplied in separate boxes.
HOT & COLD WATER INLET PRESSURES MUST BE EQUAL.
Not suitable for gravity feed systems.
The basin outlet is fitted with a flow regulated aerator insert. This low flow rate may not be suitable for connection to some Instantaneous Gas Water Heaters, some Tempering Valves, some Solar Water Heaters & some Thermostatic Mixing Valves. Check with the manufacturers of these products.
For applications where flow regulation is not suitable (e.g. bath), a full flow aerator insert has been provided within the packaging. To convert the basin outlet to a bath outlet, refer to 'Removing Aerator Insert'.
Brazed connections should NOT be made directly onto the mixer, as excessive heat will cause permanent damage.
All pipework must be thoroughly flushed prior to installation, as foreign materials may block the flow regulating device and reduce the flow of water. Note: Aerator insert must be retightened to prevent removal by hand.
Tile adhesive/grout etc. must not interfere with the removal of the protective sleeves and installation of the trim components.

Installation

Step 1: Body kit

Fit mixer body assembly (parts 10-12) onto a suitable mounting plate or noggin in the wall and secure using screws through the holes in its base. When facing the mixer, the connections should be as follows:

Hot water inlet connection 'H' below mixer cartridge.
Cold water inlet connection 'C' to the right of mixer cartridge.
Mixed water outlet connection, to the left of mixer cartridge.

Check all connections for leaks and the tap for correct operation.

Important:

Mixer body (10-12) must be installed square to wall/tile face and horizontal to ensure cover plate (5) aligns with finished tile joints.
To avoid damaging the decorative finish, do not remove the plastic protective caps until installation has been completed.

Check that the rubber seal is in position inside the rough-in cap (20) then screw cap (20) onto the G1/2B thread of nipple (12) and tighten by hand. Check all connections for leaks.

Note: Rough-in cap (20) is also used as a guide for the tiler, to ensure the hole in the wall/tile face does not exceed 40mm.

Step 2: Trim kit

Remove the protective cap from mixer body (10) and make sure the external surface of mixer body (10) is clean. Apply lubricant on the 'O'-ring, then slide sleeve (7) (with WaterMark marking underneath) over mixer body (10) up to the shoulder as shown. Screw cap (6) onto the thread of nut (8) and hand tighten to secure the sleeve (7). Remove the rough-in cap (20) & discard.

Step 3: Cover Plate

Carefully slide the cover plate (5) (fitted with seal) over the mixer body sleeve (7) & threaded nipple (12) with the 'CAROMA' logo aligned at the bottom. Push the cover plate (5) firmly against the wall/tile face then check that the thread of nipple (12) is the correct length, as shown. Cut to length if required, ensuring the end face is square. Apply thread tape to the thread.

Important: Care must be taken that thread tape cannot become dislodged and block the flow regulating device, causing a reduction in water flow. To ensure correct installation, the length of exposed thread must not exceed 8mm.

Screw the adaptor (13) onto the threaded nipple (12), using a 10mm allen key (19) until the cover plate (5) is held securely against the wall/tile face with the 'CAROMA' logo aligned at the bottom. DO NOT OVERTIGHTEN.

Apply suitable lubricant to the 'O'Rings on adaptor (13).

Step 4: Handle and Plug

Fit handle (1) taking care that it is pushed fully onto the cartridge stem, then tighten grub screw (4) using the 2.5mm allen key (3). Fit plug (2), taking care not to damage the decorative finish.

Step 5: Outlet

Carefully slide the outlet (14) onto the spigot of adaptor (13) until the back of the outlet abuts the cover plate (5) and the top face of the outlet (14) is horizontal as shown. Then tighten grub screws (17) using allen key (18). DO NOT OVERTIGHTEN.

Step 6: Final Check

Turn on Hot and Cold water supplies and check operation.

Replacing Cartridge

Step 1: Turn off supplies

Turn off hot and cold water supplies.

Step 2: Remove components

Carefully remove plug (2). The 2.5mm allen key (3) can be inserted in the gap under the handle to push out the plug (2) then to loosen grub screw (4) before removing handle (1). Unscrew cap (6) taking care not to damage the decorative finish. Unscrew nut (8) then lift out old cartridge (9).

Step 3: Fit new cartridge

Ensure the inside face of mixer body (10) is clean. Check that the seal is in position in the base of the new cartridge (9). Fit new cartridge (9) into mixer body (10), taking care that the two lugs on the base of cartridge (9) fit into the mating holes in mixer body (10).

Step 4: Reassemble

Screw on nut (8). Important:- Nut (8) should be tightened to a torque of 10 Nm. Screw cap (6) onto the thread of nut (8) and hand tighten to secure the sleeve (7).

Step 5: Fit handle and plug

Fit handle (1) taking care that it is pushed fully onto the cartridge stem, then tighten grub screw (4) using the 2.5mm allen key (3). Fit plug (2), taking care not to damage the decorative finish.

Step 6: Final check

Turn on water supplies and check operation.
