INSTALLATION

This product is suitable for concealed, falling and rising inlet supply pipes.

Exposed Shower Installation

(1) Ensuring adequate provision to allow the water to discharge safely to waste, turn on the supplies to flush the system through. Attach pressure test equipment and pressure test the system in accordance with Water Supply Regulations.
N.B. Turn off the water supply following system flushing.

(2) Construct suitable 15mm inlet supplies at level 150mm centres. Ensure the pipework protrudes a minimum of 100mm, measured from the intended finished wall surface.

Inlet water supplies As viewed from front on: Left = HOT Right = COLD

Elbow cover plates Mounting bracket

Pipe centres: 150± 1mm Adjustable: 145 – 155mm Wall plugs

Pipe tails: 18mm From finished surface

N.B. The inlet elbows are supplied at factory set 150mm centres. If required, the inlet centres can be adjusted by winding the elbows into the body to reduce the inlet centres, or out to increase the inlet centres.

(3) Once the wall surface has been finished, flush through the pipe work prior to trimming the length of the pipes to 18mm, measured from the finished wall surface.

N.B. We recommend using a rotary type cutter but if a hacksaw is used, ensure the cut is straight and the pipe ends must be carefully deburred and chamfered.

N.B. If plastic pipe is used, tube inserts must be fitted and must not increase the diameter or extend the cut off length by more than 2mm.

(4) Place valve body against the wall with elbows over the pipe tails and mark around the base where it sits on the wall. Remove valve body, place mounting bracket in centre of the outlined valve position* and mark points for fixing holes.

(5) Important – Use appropriate fixings suitable for wall type/ construction. Drill holes to suit required fixings (Use wall plugs supplied if suitable).

(6) Secure mounting bracket to the wall using the wall screws supplied (if suitable).

(7) Fit the elbow cover plates, fixing nuts and copper olives over the pipe tails and insert the filtered washers into the elbows of the valve.

(8) Making sure the outlet is at the bottom and that the elbows align with the pipe tails, push the valve body onto the mounting bracket, and secure with the two grub screws using the 2.5mm hexagonal key (supplied).
Securely tighten the nuts of the elbows using a suitable spanner.

(9) Fit the lever to the on/off and flow control handle.

(10) Turn on water supplies and check for leaks.
Refer to page 13 for shower kit installation instructions.

Concealed Shower Installation

(1)
Pre-fitting checklist
Chase out a suitable recess in the wall to receive the valve and pipework.

In most cases it will be necessary to first install a suitable sound fixing / noggin in the cavity area to secure the valve.

A hole of Ø165mm is required to install the valve and gain access to the inlet and outlet connectors.

N.B. The outlet connector can be repositioned to the top of the shower valve as required to suit plumbing arrangements. Simply swap with the blanking plug and ensure both are securely re-tightened.

Construct suitable pipework.

IMPORTANT: Servicing and Maintenance access
To enable sufficient access for ease of installation, servicing and maintenance ensure:

Hot and cold feeds to the inlet elbows of the valve are from falling or rising pipe work. (i.e. Elbow connections pointing upwards or downwards).

The inlet elbows are wound in as far as possible to keep the pipe centres to a minimum.

(2) Construct hot and cold supply pipes to the proposed siting. Ensuring adequate provision to allow the water to discharge safely to waste, turn on the supplies to flush the system through. Attach pressure test equipment and pressure test the system in accordance with Water Supply Regulations.

(3) Turn off the water supply following system flushing.

(4) Construct suitable 15mm inlet supplies at level centres and a 15mm outlet supply pipe to the desired location for the wall outlet.
Inlet water supplies:
As viewed from front on: Left = HOT Right = COLD
Pipe centres: Adjustable: 145 – 155mm
Important: The inlet elbows are supplied at factory set 150mm centres. We strongly recommend keeping the inlet centres to a minimum by winding the elbows into the body.
Pipework for the wall outlet needs to terminate in a suitable ½” female connector (not supplied).
N.B. All pipework and connectors must be secured using suitable fixings.

(5) Trim pipework to the required length. Pipe insertion depth into the elbow is 10-12mm (excluding nut and olive).

N.B. We recommend using a rotary type cutter but if a hacksaw is used, ensure the cut is straight and the pipe ends must be carefully deburred and chamfered.

N.B. If plastic pipe is used, tube inserts must be fitted and must not increase the diameter or extend the cut off length by more than 2mm.

(6) Place valve body into position with elbows over the pipe tails and mark around the base where it sits on the mounting surface.

Remove valve body, place mounting bracket in centre of the outlined valve position* and mark points for fixing holes.

(7) Important – Use suitable fixings for the mounting surface/ construction. Drill holes to suit required fixings (use wall plugs supplied if suitable).

(8) Secure bracket to the mounting surface using the wall screws supplied (if suitable).

(9) Fit the fixing nuts and copper olives over the pipe tails.

(10) Insert the filtered washers into the elbows.

(11) Making sure that the hot and cold inlet elbows align with correct supplies, feed onto the pipes and push the valve body onto the mounting bracket. Secure with the two grub screws using the 2.5mm hexagonal key (supplied).

Securely tighten the nuts of the elbows using a suitable spanner.

(12) Using a suitable coupling connect pipework to the outlet of the valve body.
N.B. The outlet connector can be repositioned to the top of the shower valve as required to suit plumbing arrangements. Simply swap with the blanking plug and ensure both are securely re-tightened. Outlet pipework needs to terminate in a suitable ½” female connector (not supplied). Refer to Shower Kit installation instructions page 11.

(13) Turn on water supplies and check for leaks.

(14) Install a cover panel (not supplied) or finish wall surface/tiles leaving sufficient access for future servicing and maintenance.
N.B. The wall plate can be used as a template for the access hole size by placing it on the valve and drawing around the plate and measuring in by 15mm to allow sufficient surface area around the hole to fit the wall plate.

(15) When the finished wall surface is completed, fit the wall plate to the shower valve and slide up to the wall surface (use a suitable sealant as necessary). Screw the lever on to the on/off flow control handle.
