STAGE 3
How the Dualush operation for this siphon works:
The full ush volume is achieved by ushing the WC in the normal fashion of fully
depressing the lever and immediately releasing once the ush has started.
The short ush volume is achieved by fully depressing the handle in the normal
fashion and holding the handle in the down position until the ushing cycle has
nished.

DUALFLUSH SIPHON
Dualush Label
High Level Cisterns: To appear on or near the lower
edge of the front of the cistern
Low Lever and Close Coupled Cisterns: To appear
on the upper half of the front of the cistern shell.
If in the unlikely event that your lling valve fails to close, all Delchem siphons feature
an internal overow which will be able to cope with upto 35l/min of excess water.
As the water level rises so will the level of water within the siphon, until it reaches
point ‘P’, the ‘spillover’ point. At this point the water within the syphon will cascade
down the down-tube and into the pan preventing any further increase in the height of
the water within the cistern.
When choosing a Delchem siphon please make sure the bottom of the coloured cap
(the ‘spillover’ point, point ‘P’ on the previous diagram) is lower than any existing exit
point within the cistern, i.e. lever handle / side lever / side inlet internal overow and
cistern rim.
