Stage 3
After two minutes the ‘SYSTEM FLUSHING’ light extinguishes and the ‘TANK FILLING’ light
illuminates. During this stage pure water enters the holding tank via the DI filter and will
continue to do so until the tank is filled with pure water. During this stage the digital TDS
monitor can be used to measure the quality of water produced by the RO filter as well as the
water quality following the DI filter. When the holding tank is full a float switch triggers the end
of pure water production, The mains water supply will be shut off at the machine, the boost
pump will stop and the UV/03 lamp will extinguish.
Stage 4
One hour after the green ‘START’ button has been pressed the ‘SYSTEM POLISHING’ light
will illuminate. For a period of seven hours a small pump draws pure water from the holding
tank passing it repeatedly through the ‘NGDI’ filter back to the holding tank. This stage
ensures that 0PPB is achieved (subject to filters being replaced at the correct intervals in
accordance with the instructions, please refer to page 32 ).
