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.
