Caroma Contura II Rail Shower with Overhead Water Efficient Tapware

Important Notes

• The overhead shower (1) and hand shower (5) are fitted with flow regulators (2) and (6). This lower flow rate may not be suitable for connection to some gravity-fed water heaters, low pressure supply networks, instantaneous water heaters, tempering valves, solar water heaters, or thermostatic mixing valves. Consult the manufacturers of these products.
• Note: Warranty is void if flow regulators (2) and (6) are not installed as shown.
• Not suitable for gravity feed systems.
• All pipework must be thoroughly flushed prior to installation to prevent foreign materials from blocking the flow regulating devices and reducing water flow.
• The shower rail (12) MUST NOT BE USED AS A GRAB RAIL.
• The centre of the drilled hole for the attachment of the shower rail mounting post (17) must be vertically aligned with the centre of the threaded nipple (16).
• Where showers incorporate flow controllers, care must be exercised during installation to ensure that the male connecting threads do not damage the flow controllers.

IMPORTANT: Pressure & Temperature Requirements

• Hot and cold water inlet pressures should be equal.
• Static inlet pressure range: 150 - 1000 kPa.
• New Regulation: -500 kPa maximum static pressure at any outlet within a building. (Ref. AS/NZS 3500.1)
• Maximum hot water temperature: 80°C.

Installation Requirements

The installing plumber is responsible for waterproofing all penetrations for taps in shower areas at installation by a proprietary flange system or a sealant. (Ref AS3740)

Diagram Description

A technical illustration depicts the Caroma Contura II Rail Shower system. It shows a vertical shower rail (12) mounted to a wall/tile face. The rail has a sliding holder (27) for the hand shower (5). At the top of the rail, a diverter valve body (15) is connected via a shower arm (4) to the overhead shower head (1). The diverter valve also connects to the hand shower (5) via a flexible hose (25). The wall mounting involves a threaded nipple (16), an adaptor (14), a mounting flange (19), and screws (18) with wall plugs (20). The rail height is indicated as 600-800mm, and the rail diameter is approximately 25mm. Numbered callouts identify individual components for installation, including: overhead shower head (1), flow regulators (2, 6), strainer washers (3, 9), shower arm (4), hand shower (5), check valves (8), screws (10, 18), allen key (11), shower rail (12), grub screws (13, 21), adaptor (14), diverter valve body (15), threaded nipple (16), mounting post (17), mounting flange (19), wall plug (20), hose fittings (22, 23, 24, 26), shower hose (25), and hand shower holder (27).

Installation Steps

1. Check that the threaded nipple (16) 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 devices, causing a reduction in water flow.
2. Screw adaptor (14) onto threaded nipple (16) until adaptor (14) is held securely against the wall/tile face. DO NOT OVERTIGHTEN. Apply suitable lubricant to the 'O'Rings on adaptor (14).
3. Mark the position for the shower rail mounting post (17) at a suitable distance from the threaded nipple (16). (Fig. 1)
4. Wall Fixing:
   • SOLID WALLS: (Brick, masonry blocks, concrete etc.)
     1. Drill a 6.00mm diameter hole, 40mm deep.
     2. Insert the tapered end of wall plug (20) into the drilled hole and tap until flush with the surface.
   • CAVITY WALLS: (Villaboard/tile etc.)
     1. Drill a 6.00mm diameter hole.
     2. Insert the tapered end of wall plug (20) into the drilled hole and tap until flush with the surface.
5. Pass the screw (18) through the hole in the mounting flange (19) and insert into the wall plug (20), then tighten until the flange (19) is mounted securely against the wall/tile face.
6. Ensure screws (13) and (21) are unscrewed out in the diverter body (15) and mounting post (17). Slide the hand shower holder (27) onto the rail (12) and position it to be on the left or right of the shower rail as desired, then lock in position by turning the lever.
7. Slide the mounting post (17) over the rail (12) with the screw (21) underneath, then carefully guide the rail assembly onto the spigot of adaptor (14) and mounting flange (19), taking care not to damage the 'O'Rings on the spigot. While holding the assembly against the wall, tighten the grub screws (13) & (21) using the 2.5mm allen key (11).
8. Check that the rubber washer (23) is installed into the shorter conical fitting (24) of the shower hose (25), then screw onto the thread end (22) of the rail (12) and tighten. Ensure the check valves (8) are fitted into the handset (5) and the strainer washer (9) is fitted into the longer conical end (26) of the shower hose (25), then screw onto the handshower (5) and tighten. Fit the handshower (5) into the holder (27). Note: The Handshower spray can be adjusted between "Firm" & "Gentle" by moving the slider on the hand shower handle up and down. The height of the hand shower (5) can be adjusted by loosening the lever on the holder (27) and sliding the holder up or down.
9. Lubricate the 'O'rings on the spigot of the diverter valve (15). Wind out the screw (10) in the shower arm (4), then install the shower arm (4) onto the spigot as shown. Tighten screw (10) using the 2.5mm allen key (11), then, if required, back off 1/2 turn to allow the arm to swivel. Ensure the flow regulator (2) and strainer washer (3) are installed in the shower head (1). Carefully screw the shower head (1) onto the thread of the shower arm (4) using a 22mm spanner and tighten. Note: To deliver water to the shower head (1), the lever on the diverter (15) must be pointing up. To deliver water to the hand shower (5), the lever must be rotated clockwise 90° to the stop.
