WATER SUPPLY REQUIREMENTS

Always maintain a 10C difference between hot system temperature and maximum hot setting of valve.
Operating Pressure Range: Min. 0.1 bar, Max. 5.0 bar When water pressure is higher than 5 bar a pressure reducing valve (not supplied) must be fitted before the mixer. A setting of 3 bar is recommended.
This valve is suitable for gravity stored, gravity boosted (pumped), balanced high pressure and combination boiler systems.
For gravity and gravity pumped systems use 22mm supply pipes and reduce to 15mm for connection to the shower valve.
Pump Installation: PUMPS MUST NOT BE FITTED DIRECTLY TO A WATER MAIN. REFER TO PUMP MANUFACTURERS INSTALLATION GUIDELINES. Ensure there is adequate flow through the pump to activate the flow switches.
Combination boiler: MUST have a minimum rating of 24kW (80,000 Btu) and be of the type fitted with a fully modulating gas valve.
N.B. Boiler performance may affect outlet temperature.
Operating pressures: Hot and cold supplies should be kept as even as possible in order to ensure the maximum efficiency of the mixer.

FLOW REGULATORS

This product is supplied with factory fitted flow regulators to maximise the temperature stability.
Flow regulators are factory fitted to the inlet connections of the valve body; these can be removed by unscrewing the inlet elbows from the valve body.
Recommendations: Mains fed/high pressure systems (e.g. combination boiler, unvented (balanced) systems and gravity boosted (pumped) – leave fitted.
Gravity stored systems – recommend removing.

INSTALLATION

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

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
   Pipe centres: 150± 1mm
   Adjustable: 145-155mm
   Pipe tails: 18mm From finished surfaceN.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. Imp or tan t- 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. Makin g 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 control handle.

10. Turn on water supplies and check for leaks.

Fitting the Shower Kit – Rail Assembly

ADJUSTABLE SHOWER KIT

1. Using a level and tape measure, make two 1.5 inch indicator lines on the finished wall surface at 590mm apart, as shown. (These will be used as guidance for fitting the rail fixing brackets).
2. Remove the chrome covers from the rail fixing brackets and set aside.
3. Keeping the fixing plates and rail inserts assembled together, temporarily push the inserts firmly into the slots located on the rail. N.B. The hole in the insert must be in the position as shown. This is to ensure that the rail ends caps line up, as per point 10.
4. Using the markings made in point 1, offer the rail assembly and fixing brackets into position.
5. Ensuring the rail is in a level position, mark the fixing points for the top bracket only.
6. Drill the holes and insert the wall plugs supplied (if suitable). Remove the fixing bracket from the rail assembly and screw to the wall using the fixings provided (if suitable). N.B. Ensure the hole in the rail insert is in the correct orientation (as per Fig.)).
7. Firmly push the rail (including the attached bottom fixing bracket) onto the secured top bracket; align the bottom bracket with the marking made in point 1, and ensuring the rail is level, mark the fixing points.
8. Repeat point 6 and utilise the slotted holes on the fixing plates to ensure level. Fit the chrome rail covers to the fixing brackets in the correct orientation, as shown.
9. Fit the hose restraint and handset holder onto the rail; the holder is tightened by rotating the lever.
10. Lining up the slots, firmly push the rail onto the fixing brackets, then lock into place by inserting the chrome rail end caps.
11. Ensuring the hose washer is in the correct position; attach the non-conical end of the hose to the valve body. Run the shower for a few seconds to clear any debris that may be present.
12. Pass the conical end of the shower hose through the hose restraint and ensuring that the hose washer is in position, attach the shower head.
13. Place the hose in the handset holder.

CARTRIDGE TEMPERATURE ADJUSTMENT

This product has been factory set under balanced pressures, and a hot water supply of 65°C.
N.B. This product can reach temperatures in excess of 50°C. If site conditions vary significantly from the factory conditions, it may be necessary to adjust the maximum temperature setting of the shower. In this case, you can adjust the cartridge to change the outlet water temperature to suit your requirements. This can be adjusted whilst using a digital thermometer and following the below instructions.

1. Carefully remove the control handle cover cap by inserting a small flat bladed screwdriver into the slot (located at the 6 o’clock position) and levering out.

2. Turn the temperature handle to the maximum hot position (flow will commence).

3. Whilst measuring the temperature of the water, insert a 2.5mm hexagonal key (supplied) into the centre of the cartridge.

4. To change the maximum temperature setting, turn the hexagonal key slowly allowing sufficient time for the temperature to stabilise.
   Increase the temperature by turning anticlockwise.
   Decrease the temperature by turning clockwise.
   N.B. We recommend a maximum temperature setting of 48°C.

5. Once the desired temperature is achieved, turn the shower off.

6. Refit the cover cap by pressing into position.

CLEANING THE THERMOSTATIC CARTRIDGE

1. Before carrying out any maintenance, ensure the water supplies are isolated. Once isolated, turn the shower on to release internal pressure. If unsure contact a qualified tradesman.
