Direct Flush Discreet
'Direct Flush' urinal valve
The Direct Flush infrared sensor controlled urinal valve provides a simple
economic solution to ensure urinal hygiene and water economy.
The Direct Flush provides intelligent automatic flushing of the individual
urinal after use ensuring the highest level of hygiene from the minimum
volume of water directly from the mains supply. Direct Flush removes the
need for the auto-flush cistern and associated plumbing used in
traditional urinal installations which flush all urinals regardless of usage.
How it operates
The Direct Flush infrared sensor detects the user at the urinal bowl,
flushing once the user departs. If a user is detected whilst flushing, the
flush is automatically arrested to prevent splashing. The flush duration is
adjustable which ensures that only the minimum water necessary is
used.
If there has been no use of the urinal for 12 hours the Direct Flush
automatically runs a hygiene flush to prevent odours and the build up of
uric acid in the pipework.
Direct Flush includes an integral DC connector (air gap) enabling the
installer to link it directly to the mains water supply. This allows fluid
category 5 back-siphonage protection, without the need for any
additional backflow prevention or check valves.
Direct Flush can be powered by either mains or batteries with both
options included as standard. Where batteries are fitted the Direct Flush
provides a low battery warning indicator. Also available is a mains power
supply unit (PSU) powering up to 20 Direct Flush urinal valves. (Only 1
fused spur required).
Additional customised washroom settings are obtainable via a hand held
remote control Infrared Configuration Unit (ICU) which is available as an
optional extra. The remote controller enables rapid automatic range
configuration to the specific washroom dimensions, deactivation of the
hygiene flush function and where a siphonic trap has been fitted,
activation of the trap refill function.
