The Direct Flush urinal valve, which is infrared sensor controlled, provides a simple economic solution to ensure hygiene and water economy.
It provides intelligent automatic flushing of an individual urinal after use, ensuring the highest level of hygiene from the minimum volume of water from the mains supply.
Direct Flush valves remove the need for the auto-flush cisterns and associated plumbing that are typically used in traditional urinal installations, which flush all urinals regardless of usage, wasting water.
Direct Flush has two installation options: Direct Flush Accessible and Direct Flush Discreet.
The mechanical contractor shall supply and install a urinal flushing device of the Cistermiser DFD type for concealed installation where service access is provided externally. A Cistermiser DFD is to be fitted to each individual urinal.
The flushing control device is to consist of a PIR sensor remotely mounted above the urinal and controlling a solenoid valve with an integral DC pipe interrupter to comply with Water Regulations.
The mechanical contractor shall supply and install a urinal flushing device of the Cistermiser DFA type for installation where service access is not provided. A Cistermiser DFA is to be fitted to each individual urinal. The flushing control device is to consist of a PIR sensor controlling a solenoid valve with an integral DC pipe interrupter to comply with water regulations.The sensor, valve and integral power supply are to be contained within a mounting unit with removable face plate to allow service access once installed. The unit is to be mounted above the urinal so that the removable face plate is flush with the finished wall surface.
The flushing control device is to be fully configurable for flush time and duration, sensing distance, flush arrest and is to be programmable either manually or by use of the ICU (remote control) where supplied. The unit should also have a programmable periodic hygiene flush function for periods of low use and a cleaner’s function to conserve water during routine cleaning and maintenance.
The flushing control device is to be suitable for connection to either 230v 50Hz AC single phase supply or from 4 x 1.5v alkaline batteries of type LR6. For multiple product installations the device is to have the option of being installed with a common power supply unit (PSUC) capable of powering several units from one 230v fused spur.
