The RObust 1000 reverse osmosis filter is designed for treatment only cold water.
On the front panel of RObust 1000 there are two pressure gauges, one of which displays the inlet water pressure after the pre-filters, and the second - the pressure after the pump in the membrane unit. In addition, for user convenience, the special information label shows recommended pressure values for pressure gauge and recommendations for resolving possible problems if these values do not correspond to those required.
If the pressure after the replacement filter is less than 1 bar, this may indicate its contamination. Procrastination with the change of replacement filters can lead to damage or destruction of the membrane. The pre-filters replacement should be changed after treatment of 8000 liters of water, but at least every 3 months. The resource depends on the consumption and quality of the purified water.
If the filtration rate drops significantly, reverse osmosis membranes must be replaced. To obtain purified water of unchanged quality, we recommend replacing reverse osmosis membranes after treatment of 24000 liters of water, but at least once a year. In the event of long breaks in the filter operations (more than 2 weeks), it is necessary to disinfect the filter (the procedure is described in details in the manual).
If the taste qualities of purified water deteriorate significantly, an unpleasant odor appears, it is recommended to replace the carbon post-filter. The post-filter should be changed after treatment of 8000 liters of water, but at least every 3 months.
