User manual FLECK 4600

[. . . ] Existing plumbing should be in a good shape and free from limescale. Always provide a by pass valve for the installation, if the unit is not equipped with one. Water temperature is not to exceed 43°C, and the unit cannot be subjected to freezing conditions. [. . . ] place the by-pass in service position and let water flow into the mineral tank. When water flow stops, slowly open a cold water tap nearby and let run until the air is purged from the unit. Otherwise, fill to the top of the air check in the brine tank. Do not add salt to the brine tank at this time. Initiate a manual regeneration, bring the valve into « brine draw and slow rinse position » in order to draw water from the brine tank until the blockage of the air check; the water level will be approximatively in the middle of the air check. Open a cold water tap and let the water run in order to drain the air out of the circuit. 24 hour wheel Program wheel in number of days between two regenerations Set the capacity of soft water between 2 regenerations using the following formula: Water capacity in m3 = exchange capacity in m3°tH ­ reserve capacity in m3 Water hardness °tH To do so, lift the transparent disc with the label and display the capacity facing the white dot. Example for the following drawing, the capacity set is 6. Use the same formula as for metered version and divide by daily water consumption to obtain the number of days between 2 regenerations. There are two time clock wheels: - 7 days: based on the week, number 1 will refer to Monday, number 7 to Sunday. Time of day Press the clutch on the 24 hour wheel, red gear, then turn the hour wheel to display the correct hour in the window. salt volume per regeneration Here is a table , usually used in water treatment. Salt weight n g / litre of resin 80 125 180 Exchange capacity in °tH / m3 / litre of resin 4 5 6 Salt weight in g / °tH / m3 20 25 30 This segment with an indicator ensures the function of brine refill. based on the table , set the amount of salt in Kg necessary for the resin regeneration. This way, the valve will send the correct volume of water in the brine tank in order to dissolve the necessary volume of salt for regeneration. Add salt in the brine tank and keep salt level above water level C. [. . . ] Hot water available only on the 4600 valve: The use of specific materials allows the valve to work at temperatures higher than 43°C: Up to 82°C for a timeclock version or 65°C for a metered version. This option allows the valve to regenerate immediately after the set capacity is consumed Fast Regeneration (FR): This option allows the valve to regenerate in 90 minutes instead of 180 minutes. This valve can only be fitted with vessels up to 10". [. . . ]
