Preparation and Completion Notes
The Britex The Dual Electronic Flush Valve No. FFV-E45 is a mains powered (transformer
240V to 12V) Electronic Dual Flush System for in ceiling or in-duct installation.
Function
A user pushes the full or half flush button to activate the flush. A new flushing cycle can only
be activated after the previous cycle has finished. Depending on the available line pressure
the full and half flush time has to be manually adjusted on the controller module to set the
required flush volume . To prevent misuse and enhance water saving the controller module
will allow only a maximum of 6 flushes per minute. Once the valve has been flushed 6 times
within one minute the controller will not allow another flush for 45 seconds.

Safety Precautions
1. The WC Electronic Dual Flush Valve and its components are for indoor use only.
2. Install the FFV-E45 and its’ components only in a dry environment with an ambient
temperature 5- 40°C.
3. When performing any work on the WC Electronic Dual Flush Valve or its’ connected
components the transformer has to be disconnected from the power supply. Also switch off
the power supply.
4. Prior to performing any maintenance shut off the water supply to the valve.
5. Prior to removing parts or disconnecting the flush valve relive the water pressure inside the
valve. The pressure can be relieved by opening the valve with the lever on the valve outlet as
shown in Fig.3. Leave the lever open until all water has drained. Close after finished.
6. The transformer and the electronic module should be installed close to each other. The
transformer and the electronic module should be installed as far away from the flush valve as
the regulations require.
7. Replace faulty components only with Sanitron original components .
8. For the installation and operation observe all relevant electrical, safety plumbing and
building standards.
9. Some equipment may radiates heat do not insulate any supplied equipment.
10. All supplied components should only be used for the purpose they are designed for.

Rough-in Installation
1. Make sure during the planning phase that the proposed installation location (see fig.1 &2)
for the flush pipe and flush valve is obstruction free (do not install additional bends or offsets
along the flush pipe other than the bend on the bottom of the flush pipe). It is recommended
to install acoustic insulation to pipe work and flush pipe in sound sensitive areas.
2. Provide a 240 V power point inside the ceiling space or service duct (see fig.1 or 2, also table
1). The cable length of the transformer is about 1.5m.
3. Install the DFM-04 electronic module close to the power point
4. Size and install the water supply pipe to the requirement of the installation (for pipe size and
installation requirements refer to the relevant standards AS 3500.1 section 10-Flush valves,
see also table 1 for technical information on the flush valve). Note: In most cases plastic pipes
require up-sizing! Install an appropriately sized ball valve as a stopcock (not supplied).
5. Prior to installing the flush valve flush the lines first.
6. Install the flush valve and the flush-pipe (40 mm DWV not supplied) in the required location
(see also fig.1 ,2,and 3). Insert the square cut flush pipe into the compression joint on the
bottom of the flush valve and tighten the nut.
7. Make sure that all pipework including the flush pipe are clipped properly.
8. Cary out all installation work as required by the pan supplier.
9. Install the supplied extension cables for the actuator buttons reaching from the DFM-04
module (see fig. 1 or 2) to the future installation location of the buttons and secure the cable
ends. It is recommended to install the cables into a cableduct. Depending on the actuator
button provide also the appropriate cutout in the wall sheeting (see also installation instruction
for the buttons).
10. For in-ceiling installation make provisions for a ceiling access panel (see fig.1) to be able
to service the flush valve. Important: When commissioning the valve for the first time or afer
maintenance. Open manual activation lever (see fig.3) first- then slowly open the stop cock
to bleed the air out of the valve. Allow the water to run for about 20 seconds. Then close the
manual activation lever.
11. Temporarily connect the flush valve and operate the valve several times then check all
plumbing connections on the valve for leaks. Disconnect the valve after testing.
Installation Instructions
Supplied
Supplied with the Britex The Dual Electronic Flush Valve FFV-E45 are the following

Fit out
1. Connect the activator buttons to the extension cable that had been previously installed.
2. Connect the extension cables from the buttons and the solenoid valve to the DFM-04
module (see also fig.5).
3. Plug the transformer lead into the DFM-04 module (see also fig.5).
4. Plug the transformer into the power point and switch on the power.
5. Important: When commissioning the valve for the first time or afer maintenance. Open
manual activation lever (see fig.3) first-then slowly open the stop cock to bleed the air out
of the valve. Allow the water to run for about 20 seconds. Then close the manual activation
lever.
6. Adjust the flush time settings on the DFM-04 module (see f ig.5) to the correct flush volume
according to the requirements of the toilet pan (refer to the pan suppliers instructions).
a) Temporarily connect a measuring bucket to the end of the flush pipe.
b) Open the flush valve stopcock and activate first full and in a separate test the reduced flush.
c) Compare each collected water volume with the required flush volume.
d) If too much water is discharged shorten the flush time. With a small screwdriver turn
the relevant dial on the controller anti clockwise (see fig.5). Caution do not force the
potentiometer dial beyond the min. setting
e) If not enough water is discharged extend the flush time. With a small screwdriver turn the
relevant dial on the controller clockwise (see fig.5). Caution do not force the potentiometer
dial beyond the max. setting
7. After testing install the buttons into the prepared wall cutout.
8. Install the toilet pan.
9. Activate the valve several times. Check on the valve that there is no water spillage on the
airbrake. It is possible that the flush valve will squeak for the first few operations . It is caused
by trapped air inside the valve. The squeaking should stop after a few flushes. Note: If the flush
valve is activated more than 6 time within one minute it will stop flushing for 45 seconds.

Valve Diagram (fig. 3)
A) To lower the flow rate of the valve turn screw with a
flat screwdriver in (clockwise). The factory
setting is 2 turns in from all the way out. To increase the
flow turn screw out (anticlockwise).
Note: Do not force screw past its stops.
B) Open the manual actuation lever to test, bleed
or depressurise the valve. To open quarter turn lever
90 degrees clockwise. To test and bleed (open) the
valve without the power connected turn lever 90
degrees clockwise.
C) Insert the 40 mm DWV flush pipe into the
compression connection on the bottom of the flush
valve and tighten the nut. Also install pipe clips to
secure the flush pipe
Hydraulic conditions required at the flush valve (table 1)
Hydraulic Conditions
Min. flow pressure 250 kPa
Min. flow rate at the valve 1.5 I/sec
Max. flow pressure to AS 3500.1 500 kPa
WELS rating: 4 STAR
Mini. Water temperature: 5° C
Max. Water temperature: 30° C
Ambient temperature: 5-40° C
Min. connecting pipe size from the ring main to the valve {see below**) 25 mm copper or
equivalent. 25mm plastic pipe is not the equivalent to 25mm copper. Plastic pipes have to be
appropriately up-sized.
The flush valve is designed to operate of a water supply equivalent to potable water
standards.
**Refers to the minimum connection pipe size to any valve branched off the ring main pipe
providing that the above required technical specifications can be met. Pipe work to the valve
fixture must be sized to and installed to water service rules and regulations (AS/NZS 3500.1
section 10 and local regulations) and simultaneous demand requirements. To ensure proper
sizing of the pipe work for the valve it is recommended to engage a qualified hydraulic
designer.
