When the preset value for the conductivity is exceeded, the conductivity monitoring triggers the same process as the "Empty pump basin" button. The subsequent utilization of fresh water for the washing process dilutes the remaining salty water in the basin system to an extent that adequate washing water quality is restored. This option cannot be installed if the recycling system is not equipped with an overflow from the recycled water tank and a fresh water supply. Recycling water recirculation If the washing system does not use up the water, the recycled water is circulated to avoid foul odour. During frost, put the system out of operation and remove all traces of water:  Loosen the screws of the plastic pipes and let the pipes run empty. σ Open the gravel filer and remove the gravel that is still moist (Customer Service) Empty pump basin With this function, the recycled water is channeled from the pump basin into a channel. € This function is required when the quality of the recycled water proves insufficient for operating the awashing system (too much salt in the water or wrong cleaning agent, for example). € Gravel filter (flow direction of filtering) – Shutoff valve recycled water – to the recycled water tank Backwash During backwash, the water flows via – Immersion pump – multi-channel valve in position RÜCKSPÜLEN/BACKWASH. € Gravel filter (against flow direction of filtering) – Restrictor – To the sludge collector In order to prevent sand from being forced out, the volume flow is restricted by a throttle during the backflow phase. The backflow speed was set up by a specialist during the machine startup and must not be modified. final rinse During final rinse the water flows via – Immersion pump – multi-channel valve in position NACHSLPÜLEN/RINSE. € Gravel filter (flow direction of filtering) – To the sludge collector Processed water circulation Purpose of circulation: – Additional movement of the recycled water, especially when the washing system has come to a standstill, to avoid formation of brackish water and reducing the odour problem. € Additional supply of air to the water to avoid odour problem The water flows from the recycled water tank to the sludge removal as follows: – Recycled water tank – Circulation valve – Circulation pump – Sludge removal EN -5 17 Monitoring and regulating equipment Float switch in the recycled water tank S7 up S7 down S9 up S9 down S11 up S11 down Floater switch in the pump basin S5 top* S5 bottom* S14 top S14 bottom S15 top S15 bottom * S5 optional Pump basin overfilled. Starting the disposal via the recycled water tank into the channel Pump basin is not overfilled, normal system operation. No function / switch point is not used Pump basin is not empty, normal system operation. operator/ Customer Service Operator Check recycled water for odour and turbidity. See section on "troubleshoot- Operator ing" for measures against poor quality of recycled water. Check the detergent dose at the washing unit if there is too much foam for- Operator mation. Trigger the manual backwash or change gravel if capacity is too low; contact customer service if necessary. Operator Operator Check the status of the float sensors; inform Customer Service, if required. Operator After sludge has been collected, there should be no sludge in any of the ba- Operator sins. [. . . ] The plant must be secured through a wrong current protection switch with a triggering current lesser than or equal to 30 mA. € The appliance may only be connected to an electrical supply which has been installed by an electrician in accordance with IEC 60364. € The voltage indicated on the type plate must correspond to the voltage of the electrical source. 0 Installing the unit (only for experts) Notice The equipment may only be installed by an – mechanic of Kärcher – or an from Kärcher authorized individual Preparing the installation place The following requirements are necessary in order to install the equipment: – frost-free room with adequate ventilation and exhausts – Floor path for collecting sludge – Pipes and underground construction as per drawings 0.
