Via a three-way valve the high-pressure pump is connected to a suction nozzle leading to the outside. Function The self-priming pump withdraws fluid from the rainwater storage tank via the suction nozzle. If the rainwater storage tank is empty, the pump can withdraw water from the mains water storage tank. To this end, the pump is fitted with a three-way valve providing it with a second suction nozzle towards the mains water storage tank. The mains water storage tank contains a water volume of approximately 13 litres, which is automatically replenished from the public water supply system or from other (service water) pressure lines via a float valve. If a sensor indicates that the rainwater storage tank is empty, the system will automatically switch to the mains water storage tank from which it will withdraw water until the rainwater storage tank contains a sufficient amount of water again. Once the rainwater storage tank contains enough water again, this condition is signalled to the system, which will then automatically switch back to rainwater mode. The pump is started and stopped automatically when a consumer installation is opened and closed.

Hya-Rain/Hya-Rain N Monitoring equipment For monitoring purposes, the system is equipped with a pump control unit in the discharge line, which starts the pump as soon as the pressure drops below 2.5 bar (factory setting) and stops it (with an after-run time of approx. 10 seconds) when the consumer installation is closed. At the same time, this device protects the pump against dry running. A lift check valve fitted in the control unit prevents the pumped water from flowing back. The pressure is indicated by a fitted pressure gauge. 4.6 Noise characteristics Depending on the operating data of the system, the noise level will be approximately 49 - 50 dB(A). 4.7 Dimensions and weights Dimensions For the dimensions refer to the outline drawings of the system.

Press the Timer key three times. ð The display shows the replacement time in minutes. (The replacement time is the time the pump requires to pump the tank empty. This time depends on the consumption. If only toilet flush boxes are connected it will take longer; if a garden tap is connected, the tank will be emptied in a shorter time. Factory setting 3 minutes.) 4. Press the Percentage key to change this value. 5. Press the Timer key four times or wait for 20 seconds. ð The display changes back to display mode "Fill level in %". 6.1.4 Start-up The system is in operating mode as soon as it is plugged into the mains. 6.1.5 Functional test Checking the dry running protection function ü The system has been properly set up, installed, connected and commissioned. 1. Close the suction-side water supply (from the rainwater storage tank). ð The pump control unit permanently monitors the system for dry running. Should insufficient fluid be fed into the system from the suction side (no flow), the pump control unit will trip after 10 to 15 seconds. This after-run time can be repeated by pressing the reset key. Checking the modes of operation ü The system has been properly set up, installed, connected and commissioned. 1. Check that the indicator lamps light up. Rainwater storage tank This indicator lamp lights up when the pump withdraws water from the rainwater storage tank. Mains water mode This indicator lamp lights up when the pump withdraws water from the mains water storage tank and the mains water back-up system is activated. Automatic mode This indicator lamp lights up when the pump automatically switches to the available water tank.

Hya-Rain/Hya-Rain N 7 Operation CAUTION Incorrect operation Damage to the pump system! ▷ Make sure to comply with all local regulations, particularly the EC Machinery Directive and the EC Directive on Low-Voltage Equipment. ▷ Check all electric cables prior to commissioning/start-up. 7.1 System control 1 4 5 6 7 2 3 1 4 5 6 7 A B Fig. 7: Hya-Rain, Hya-Rain N system control panel A Hya-Rain N system control panel B Hya-Rain system control panel 1 Master switch 2 Indication of water level in rainwater storage tank 3 Setting keys 4 Operating mode selector switch 5 Actual pressure indication 6 Cervomatic ME (pump control panel) 7 Operating mode indication 1 2 3 Fig. 8: Operating mode selector switch 1 Automatic operation 2 Manual mains water mode 3 Manual rainwater mode Automatic mode The pump withdraws water from the rainwater storage tank and pumps it into the consumer system through the pump control unit (green "rainwater mode" LED is lit). The pump is in operation as long as the consumer installations (toilet flush box, washing machines, garden watering systems) are open. When they are closed, the pump will continue to run for approximately 10 - 15 seconds and will then automatically stop. When the rainwater storage tank is empty, the control unit will switch the pump to mains water mode (green "mains water mode" LED is lit). As long

Hya-Rain/Hya-Rain N as the pump is running, i.e. as long as water is withdrawn, mains water will be supplied via the float valve. The quantity of mains water supplied will not exceed current actual requirements. Such mains water quantity depends on the inlet pressure of the public water supply system. The system will return to rainwater mode as soon as the water level in the rainwater storage tank has risen back up to the minimum level. Mains water mode In this mode the system exclusively withdraws mains water, even if the rainwater storage tank is filled (green LED is lit). This mode can be selected if the mains water in the mains water storage tank needs to be changed or whilst work on the rainwater storage tank is under way. Rainwater mode In this mode the system exclusively withdraws rainwater until the rainwater storage tank is empty (green LED is lit). This means the pump can be tripped by the dry running protection of the pump control unit. This mode can be used to pump the rainwater storage tank dry. Priming Before withdrawing water from the rainwater storage tank for the first time, the pump must be filled with water. This is done automatically when the system has been connected to a 230 V mains and the operating mode selector is set to mains water mode for approx. 15 seconds. For priming, a consumer installation (e.g. garden tap) must be open, the pump master switch must be set to 1 and the operating mode selector switch set to rainwater mode. Keep the reset key pressed until the pump is operating normally. The pressure gauge indicates 2.5 to 4 bar. This procedure may take up to 4 minutes. Should the priming process take longer, please check and verify that the suction losses correspond to the system specification, the suction line is completely tight and the end of the suction line is sufficiently submerged. 7.2 Pump control unit 1 2 3 Fig. 9: Pump control panel 1 Green LED 2 Red LED 3 Reset key When a consumer installation is opened, pump operation starts automatically. When the consumer installations are closed, the pump stops automatically. Lack of water will activate the integrated dry running protection function, so that the pump stops automatically. A lit green LED indicates operational availability. A lit red LED indicates lack of water or a fault. The reset key allows resetting of the fault message. The control unit is in manual mode as long as the reset key is pressed and held.

Hya-Rain/Hya-Rain N 7.3 Level control system A B Fig. 10: Level control system A Percentage key B Timer key Level control and measurement are effected by a capacitive system. The sensor delivered is supplied with a voltage of 12 V by means of the optional connection cable; this voltage is not hazardous to humans. A 2-wire rubber-sheathed cable of 1 mm2 to 1.5 mm2 is appropriate as connection cable. Already routed float switch cables of up to max. 50 m length can be used for retrofitting. The signals of the two sensors are analysed in steps of 1 % via a digital control's capacitive resistance. Pressing the % key will adjust the system to the plant-specific conditions. The sensor cable length immersed in the fluid will be calibrated to 100 %. Once the water level has dropped from 100 % to 5 %, the system's level control will switch to mains water mode. If the water level in the rainwater storage tank rises above 7 % again, e.g. after rainfall, the system will automatically return to rainwater mode. In case of any connection or sensor failure, the message FE (failure) will be displayed. To set the system to switch automatically to mains water mode, press the Timer key to open the relevant menu. This function allows automatic replacement of the water stored in the mains water storage tank every 10 - 60 days. This function is only enabled if the pump withdraws water from the rainwater storage tank.

Hya-Rain/Hya-Rain N 9 Trouble-shooting WARNING Improper work to remedy faults Risk of injury! ▷ For any work performed to remedy faults, observe the relevant information given in this operating manual and/or in the product literature provided by the accessories manufacturer. If problems occur that are not described in the following table, consultation with the KSB customer service is required. Table 7: Trouble-shooting Fault/malfunction Possible cause Remedy Pump is running, but does not deliver. Pump has not been primed. Excessive suction losses Prime the pump. Reduce suction head. Choose larger cross-sections. Leaking suction line Eliminate leakage. Air pocket in suction line Fill suction line or lay with rising slope. Suction strainer clogged Clean the suction strainer. Discharge line shut off Open discharge line. Excessive start-up frequency of the pump Leaking consumer installation Eliminate leakage in consumer installation. Swing check valve leaks. Fit new swing check valve or new pump control unit. Very low level of consumption, minimum flow rate not achieved. Increase toilet flush volume (clean strainer in toilet cistern, if necessary). Pump is running but delivering insufficient flow rate or pressure. Pump takes in air. Check suction line. Suction strainer clogged Clean the suction strainer. Pump stops during operation. Power failure or undervoltage Check power supply. Thermal switch tripped because of overheating Check the pump for smooth operation. Earth leakage circuit breaker tripped Have the insulation resistance checked by a trained electrician. Pump stops during operation; "fault" is indicated. Air in suction line Flush the suction line by opening several consumer installations and pressing the reset key for approx. 3-5 minutes. System does not start. Pump control unit indicates "fault". Press the reset key or interrupt the mains voltage. System does not stop. Foreign object in pump control unit Clean pump control unit and replace it if required. Excessive noise level Pump in contact with securing screws Align the pump manually ensuring that it does not come into contact with the screws. Tank overflowing Dirt deposits in valve Remove dirt/limescale deposits in valve; replace float, if necessary. How to avoid pressure surges Increasing the suction line diameter DIN 1988, Part 3, stipulates that for withdrawal rates > 0.5 l/s an inside pipe diameter of at least 20 mm must be selected. Setting of the pressure reducer If the pressure gauge indicates a pressure of 5 bar with the valve closed, and this pressure drops to 2.5 bar when the valve is opened, the pressure applied when the valve is closed must be reduced by at least 1 bar. Pressure surges occur whenever the pressure differences exceed 2 bar. Eliminating pressure surges by throttling the flow If an isolating valve or a pressure reducer is fitted in the mains water supply line upstream of the system, the valve/reducer must be throttled until the pressure surge is eliminated. The drawback of this method is the low mains water back-up flow rate.

Hya-Rain/Hya-Rain N It must be checked if the flow rate is still adequate to meet standard consumption requirements. The lack-of-water monitoring equipment must not trip in mains water mode when the max. quantity of water that can be withdrawn is withdrawn. If the lack-of-water monitoring equipment does trip, the discharge side flow rate must also be throttled. Membrane-type accumulator Fit an 8-litre membrane-type accumulator in the line upstream of the system inlet. Such an accumulator will attenuate extreme pressure drops in small-diameter pipes and absorb surges without throttling the flow rate.
