Flushmaster Flush ValvesWATER-SAVING TOILET FLUSH MECHANISMS
The flush valves allow for adjustable water delivery and non-hold open function. These can be presetto deliver only enough water to clean the urinal or toilet and no more. They also cannot be left in theopen position, and therefore have to be re-activated for another flush.
Cobra Flush Valves
The dual flush toilets are fitted with a dual flush activation that will dispense either a 3 litre or 6 litreflush.

FM1.000, STANDARD MANUAL FLUSHMASTER FLUSH VALVEBASIC INSTALLATION GUIDE
Please take note that the following fixtures/ installations should be completed before installing theflushmaster flush valve:
The water supply line should be ideally installed in a brick wall (110mm or 230mm) and the pipingshould be chased into the wall. The water supply line should then be plastered/ tiled closed.This will prevent unnecessary movement of the flushmaster flush valve when operated.

Drain line
Waste pipes

Install the control stop assembly (BC-FM8.60)- - and wall flange. PFT-tape or hempshould be used on the male threads to create aleak-free coupling.

FM1.000, STANDARD MANUAL FLUSHMASTER FLUSH VALVEBASIC INSTALLATION GUIDE
All plumbing is to be installed according to the applicable regulations, rules, codes and procedures.Water supply lines and piping must be sized to provide the adequate volume of water for every
flush cycle (60l/ min).Take note of the minimum required operating pressure (30 - 300kPa) of the device (a pressure
pump may be installed to increase the water supply pressure to the minimum required/ desiredlevels).
Take care not to exceed the maximum operating pressure (600kPa) for the specific device (a PRV- pressure reducing valve) can or should be installed on the main water supply line to balance
the water pressure.Flush all water line prior to installation to clear it of any potential debris.
Do not use any toothed tools to install or service the flushmaster flush valve - this will result in“ ”
IMPORTANT NOTE:
INSTALLATION PROCEDURE (only for the Flushmaster flush valve):
2) Prior to inserting the flushmaster flush valve“tailpiece” - - (the end which inserts intothe control stop assembly), take note that the“o-ring” seal - - is located in the “o-ring sealgroove” (see the end of the “tailpiece”) and thatthe “lock nut” - - and “double cap seal” - -are located and positioned as shown.

Determine the length of the flushpipe/ vacuum breakertube - . This pipe is required to connect the flush-master flush valve and the water closet (toilet) and asindicated above, it comes in various lengths (verticaland bent).
5) Hand-tighten the coupling nut at the insertion of theflushpipe to the flushmaster flush valve and insert therubber pan connector into the opening of the watercloset (toilet). Ensure that the rubber pan connectorfits tightly and insert it fully to establish a proper seal.
6)
G
Before the water supply isturned on, ensure all stopvalves to the flushmasterflush valve are closed offproperly. The stop valvescan be opened/ closed/adjusted using theadjustment screw (at thecentre of the control stopassembly) - .
If for any reason the control stop valve needs to be removed completely,ensure that the water supply is turned off completely.

The flow-rate, cycle time and flow pressure
in flush valves can be adjusted at the
ball-o-stop screwdriver slot (indicated by
arrow on the line drawing on the left).
The ball-o-stop setting should be such that
there is no splashing whilst ensuring an
adequate flush to clear the pan/ urinal.
Flush time can be adjusted by loosening
the grub screw under the pushbutton and
rotating the knulled button surround 180
(indicated by black dot on the line drawing

15mm Ø Pipe or 15mm Ø Watermeter must not be used for toilet flush valves.Friction loss across a 22mm Ø Watermeter has been taken into account (see table above).Maximum distance as indicated may be increased by 25%, if PVC/ HDPE pipe is used.The table is illustrative of single storey domestic applications only and for any other installations,you should consult your Plumber or suitably qualified person to do so.

Cobra Demand Taps
Cobra Metering Taps
The demand taps allow water to flow only as long as the button is held down. They cannot be leftrunning. This feature makes demand taps the ideal choice for public facilities. Only one hand can bewashed at a time.
The metering taps allow an adjustable water delivery time from 1 second minimum. They can bepreset to deliver the minimum amount of water required. Water is dispensed only after the pushbutton has been released. The unit can not be jammed open, both hands can be washed at the sametime.
