 Check the position of the stirrup

If the stirrup (m) is correctly positioned
on the basis of the below table, proceed
to step ➏. Otherwise, carry out all of the
following steps:

Unclip the lift rod (c)

➊

Remove the stirrup (m) , by pressing on

➋

the two catch clips (k)

Cut the overflow (l) if necessary according

➌

to the table

Reposition the stirrup in its seat and slide

➍

it to the required position (desired setting
notch number visible)

Clip lift rod (c) back into the hole of the

➎

overflow (l) which has the same number as
that of the setting notch

Unscrew the strainer nut (f)

II - INSTALLATION

Position the mechanism
in the cistern and secure
it in place with the nut (f)

Manually screw the
flush valve nut (f) until
it is in contact with
the ceramic. If
necessary give an
extra quarter turn
(maximum) with the
appropriate spanner.

NB : Excessive
tightening can damage
the mechanism and
would not be covered by
the guarantee.

IV - SETTING WATER LEVELIII -

After having connected your ballcock to the water
supply, open the tap and set the level of the long flush
using the ballcock (see overleaf).

Note: The max. water level should be 20 mm lower
than the overflow tube (l).

To adjust the water level of the short flush, slide the
cursor along (j). Immerse the cursor of 40 mm.

Note : The closer the cursor is to 18, the more
water will be flushed.

V - INSTALLATION OF BUTTON

Once the set-up has been completed, put on the lid

➊

on the cistern

If the hole in the lid (D) is > 38 mm and < 45 mm,

➋

remove the escutcheon (b)

Position the button on the lid and screw until tight.

➌

In some (rare) cases, the residual water level
(amount of water remaining after the long flush)
must be increased to ensure more efficient
cleaning. To do this, move the sliding valve (d) to
the left (the more it is open, the more the residual
water increases).

Note: Increasing the residual water reduces the
volume of water flushed. If necessary, readjust the
max. water level using the ballcock.

VI - MAINTENANCE
