General Care & Safety

Wall plugs supplied are ONLY suitable for solid stone/brick walls. They are not suitable for use in aerated blocks or similar. If fixing to a stud wall, sufficient extra internal reinforcements must be made to the wall. Screws must locate into suitably reinforced studs and noggins.

Take care using power tools – The use of a residual current device (RCD) is recommended. Beware of hidden cables or pipes when drilling.

This product can be dangerous if installed incorrectly. This product must be installed by a qualified plumber or installer. It is the installer’s responsibility to check that the fixings are suitable for the installation in hand.

Cistern fittings are suitable for Water pressure: 0.1 – 10 bar. Do not add caustic chemical substances (e.g. containing chlorine compounds or similar) into the cistern. These can damage the valve components and cause failure.

Before starting to enclose the cistern, the system must be first tested for leaks before 2nd fix commences. Temporarily fix the back to wall pan in place and make connections. Turn the water supply on and flush the pan to check for leaks. This is particularly important to do prior to tiling for fully tiled in installations

This cistern is not suitable for use with wall hung pans without the use of a suitable supporting frame.

How to Access your cistern


  1. Remove fascia panel

  2. Remove the blue cover on the cistern

  3. Shut off Water Supply

  4. Unscrew the nut from the flexible hose

  5. Pull out the fill valve

  6. Gently twist & remove flush valve (anti-clockwise)

Problem Potential cause Suggested action

The Fill Valve does not work or isn’t controlling the water supply efficiently.| The inlet valve may be blocked.

| Follow the instructions below and clean the water inlet orifice, diaphragm and cap. If split or scaled up, replace the diaphragm, available as SP19756.

1

a) diaphragm SP19756

2

To clean the aerators, remove the cap from the top of the inlet valve and remove the aerators by pushing them out from underneath the outlet hole using a screwdriver or equivalent

3

If the flow rate is still too slow, the filter can also be removed from the inlet of the valve for cleaning using long nose pliers. Ensure to reinsert the filter before reconnecting the water.

Water leaks from the base.| 1 The flush valve stem may be obstructed or jammed, preventing it from falling back into position.

| Ensure that there is nothing obstructing the flush valve and the stem can extend up and down.

2 The rubber flapper seal may have fallen off, may need cleaning or could be damaged.

| Ensure the flapper seal is fixed in position. However, If it’s damaged a replacement is needed, this is available as SP12551.

NOTE:
Before re-fitting the flush valve assembly check the base is correctly seated as shown to the left and not out of position (see below as an example)

3

| Ensure the rotation of the blue, reduced flush float is in the correct position, and has locked in place securely.

If it isn’t (as shown left) the float can catch on the adjustment measure. To lock in place, simply rotate the float anticlockwise.

The flush valve does not work properly.| The pneumatic tubes may be pinched or may have been installed incorrectly.| The blue tube must be connected to the joint marked with a half circle,

The transparent tube should be connected with the joint marked with a full circle.

Ensure the same configuration is used on the flush button

The pan washer is leaking.| The cistern may have been installed in an incorrect position causing the flush bend to pull out of position, or silicone has been used around the rubber seal.

  1. rubber seal

| Ensure the cistern is in the correct position and ensure the flush bend is fully connected to the pan. NEVER use silicone on the rubber seal as this will impair the ribs and prevent a proper seal being formed.

Please see the instruction manual provided for fitting instructions.

Water leaks between the cistern and base| The nut connecting the flush bend with the cistern body may not be tightened sufficiently.

| Ensure the nut is fully tightened by hand and the flush pipe is vertically installed into the flush valve.

Note – do not over-tighten

The pneumatic push button doesn’t reposition itself once pressed downwards| It may be a fault with the air compression or the button itself could be broken

| Check the pneumatic tubes are connected properly. If the button is faulty then it will have to be replaced with another one, available as SP12169.
