Typical Layout for Dux Centreflush2 Cistern
INSTALLING
1. Take the lid off the cistern leaving the protective film in intact, it is preferable to leave this intact until any paint work
is completed.
2. Fit the Flushpipe to the back of the pan and if necessary cut the short leg of the flushpipe so that when fitted to the
pan it is 80mm from the wall to the centreline of the flushpipe.
3. Fit the reducing bush supplied to the top of the flushpipe and then sit the cistern onto the bush. Making sure that the
horizontal leg of the flushpipe is horizontal. Measure the distance from the top of the cistern to the required height line
as established in step 2 (Setting out). This measurement is the amount to cut off the long leg of the flushpipe. Remove
the cistern and flushpipe from the pan and cut the flushpipe accordingly.
4. Drill and fit the four mounting screws to the wall at the position established in step 3 (Setting out) leaving the screw
protruding from the wall approximately 10mm.
5. Re-assemble the flushpipe onto the pan with the reducer bush and the flushpipe nut then lower the cistern onto
flushpipe and the four mounting screws.
6. Tighten the four mounting screws and Flushpipe nut.
7. Flush any dirty water out of the water supply to prevent dirt and debris from clogging the valves.
8. Install the inlet valve, turn on the water supply and adjust the water level to the required flushing volume.
Installation and adjustment guidelines are on the back of this page.
9. Fit the cistern lid and check the operation of both the full and half flush modes.
Note: If fitting the cistern to hardboard or gib board and there is no backing timber we suggest the use of “Toggles”
which are readily available from hardware stores.
Installation & Adjustment
The inlet valve can be fit to either the left or right side of the cistern.
Once fitted you will need to turn the water supply on and adjust the float up
or down until you have the desired full flush volume.
4.5 L, 6 L or 9 L as marked on the inside edge of the cistern. To adjust the
water level, turn the adjustment screw on the side of the valve.
Service & Cleaning
It is possible that small debris can prevent the valve shutting off.
To remedy this, the diaphragm can be cleaned as follows,
1. Unclip the adjustment screw from the float arm
2. Rotate the diaphragm nut anti-clockwise and remove the
diaphragm.
3. Rinse valve and diaphragm under running water to remove any
debris.
4. Re-assemble in reverse order
The button rods can be adjusted by screwing up or down
the rod. After adjustment there should be 1 -2mm gap
between the button rod and valve.

INSTALLATION INSTRUCTIONS
DUX CENTREFLUSH2 CISTERN
Code: CFDFUWWH2
DURABILITY:
Dux cisterns comply with the NZBC durability requirements of 5 years, if installed and maintained in accordance with these
instructions. The installer is responsible for the workmanship of the installation. The product is intended for the flushing of
W.C. pans in commercial and residential applications. The approval of the distributor must be obtained for all other
applications.
GENERAL:
To achieve satisfactory operation it is important to fit the 40mm Flushpipe supplied and the most efficient flushing is
obtained with the cistern mounted as high as possible on the wall. If it is desirable to reduce the height, cut the flushpipe
to suit, however it is suggested that for good flushing the flushpipe should be at least 300mm in vertical length.
This cistern is supplied with an internal overflow so no external overflow is required.
CHOICE OF SEAT:
It is important to ensure that the seat will remain upright when lifted. This is a function of the model of seat and the
distance the pan is set from the back wall.
We recommend the use of Dux toilet seats,
1. Dux Twinline or Classic seats in which the hinging point is forward of the seat mounting holes in the pan.
2. Dux Royal or Regent seat these seats should be fitted onto the pan first and then checked to see that the seat will
stay upright when lifted. The full length flushpipe is usually sufficient with most pans if the front edge of the pan is
at 710mm from the back wall.
INCREASING/DECREASING FLUSH VOLUME:
This cistern as supplied is factory set for a 6 litre full flush and 3 litre half flush when used with a 6-litre pan that complies
with AS1172.1:1993.
If required this cistern can be adjusted to a 4.5/3 litre flush (4 star rating) when used with a 4.5 litre pan.
When older style pans are used it may be necessary to increase or decrease the flushing volume to achieve satisfactory
flushing. The flushing volume can be increased or decreased by easily adjusting the valve adjustments shown on the back
of this page.
SETTING OUT:
1. Mark a vertical centreline on the wall on which the cistern is to be mounted in line with the centre of the pan
outlet.
2. Position the cistern central with the vertical line using the centreline on the top inside face of the cistern and at the
previously determined height. Make sure that the top edge of the cistern is level and pencil a line along the top
edge of the cistern.
3. Mark the position of the four mounting screw points
4. Position the water inlet either on the horizontal line 66mm below the top edge of the cistern at no less than
350mm from the centreline or if a vertical supply tube with a bend is preferred a Dux Qickee supply kit plus a
NFE23FWH bend is available as a separate kit. Part No. NIV22500FWH. In this case position the inlet at 300mm
from the centreline and at 600mm to 400mm from the top edge of the cistern.
