Original instructions Under our sole responsibility, we hereby declare that these pumps/domestic water systems/auto- matic domestic water systems, identified by type and serial number *1), comply with all relevant requirements of the directives *2) and standards *3). Technical documents for *4) - see page 3. This device is used for conveying clean water in the house and garden area, for sprinkling and watering, as a well pump, rain pump and domestic water pump and for pumping out swimming pools, garden ponds and water tanks. The maximum permissible temperature of the conveyed medium is 35 °C. The device must not be used for drinking water supply or for conveying food supplies. Explosive, combustible, aggressive or other substances that are harmful to health must not be conveyed. The device is not suitable for commercial or indus- trial use. This device is not designed for use by persons (including children) with limited physical, sensory or mental aptitude or lack of experience and/or knowledge. Unauthorised modifications to the device and the use of parts that are not tested and approved by the manufacturer are prohibited. All improper use of the device is regarded as non- specified use; this can result in unpredictable damage! The user bears sole responsibility for any damage caused by improper use. Generally accepted accident prevention regula- tions and the enclosed safety information must be observed. For your own protection and for the protection of your appliance, pay atten- tion to all parts of the text that are marked with this symbol! WARNING – Reading the operating instructions will reduce the risk of injury. WARNING Read all safety warnings and instructions. Failure to follow all safety warnings and instructions may result in electric shock, fire and/or serious injury. Keep all safety instructions and information for future reference. Pass on your pump only together with these docu- ments. Information in these operating instructions is cate- gorised as shown below: Danger! Risk of personal injury or environ- mental damage. Risk of electric shock! Risk of personal injury by electric shock. Caution! Risk of material damage Children, adolescents and per- sons who are not familiar with the operating instructions must not use the device. Children should be supervised to ensure that they do not play with the appliance. When the pump is being used in swimming pools and garden ponds and in the protected areas around them, the provisions of DIN VDE 0100-702 and -738 must be observed. The device must be supplied via a residual-current device (RCD) with a rated residual current of max. 30 mA. The device must not be used if there are persons in the water. When used for domestic water supply, the statutory water and waste water specifications according to DIN 1988 must be observed. The following residual risks essentially remain when operating pumps and pressure vessels can- not be fully eliminated (depending on features) – even if safety meas- ures have been introduced.

4.1 Danger from the environ-

ment! Do not expose device to rain. Do not operate device in a damp or wet environment. Do not use the pump in hazardous areas or near inflammable liquids and gases!

4.2 Danger: Hot water!

Danger! Install a check valve at the suction connection (12) to prevent water from flowing back into the suction line. This can reduce the following danger: Hot water can cause damage and leaks on the pump and the con- nection lines, allowing hot water to escape. Danger of scalding! Devices with the designation HWW...: If the shut-off pressure of the pressure switch cannot be reached due to poor pressure conditions or a defective pressure switch, the water can heat up within the pump as a result of internal circulation. Devices with the designation P...: Operate the pump a max. of 5 min- utes against the closed discharge line. Water that circulates inside the device is heated up. In the event of a fault, unplug the pump from the power-supply sys- tem and allow to cool. A specialist must check the system to make sure it is in perfect working order before it can be used again.

4.3 Danger! Risk of electric

shock! Never direct the water jet directly at the device or other electrical components! Risk of fatal electric shock! Prior to installation and mainte- nance tasks, always disconnect the device from the power-supply system. Do not touch the plug with wet hands! To disconnect, always pull on the plug, not the power cable. Do not buckle, squeeze, drag or drive over power cable or exten- sion cables; protect from sharp edges, oil and heat.

4.4 Danger due to device defi-

ciencies or malfunctions! Before each use, check the device for possible damage - especially the mains cable, mains plug and electrical components. Risk of fatal electric shock! A damaged device must only be reused after it has been correctly repaired. Do not attempt to repair the pump yourself! Only specialists are per- mitted to repair pumps and pres- sure vessels (depending on fea- tures). Caution! To prevent water damage, e.g. flooded rooms, caused by device malfunctions or deficiencies: - Introduce suitable safety meas- ures, e.g.: alarm system or col- lecting tank with monitor The manufacturer is not liable for any damage caused by: - improper use of the pump; - overloading of the pump through continuous operation; - failure to operate and store the pump in a frost-free environment; - unauthorised modification of the pump (repairs to electrical equip- ment may only be carried out by qualified electricians!); - use of spare parts which have not been tested and approved by the manufacturer; or - use of unsuitable installation materials (fittings, connection lines etc.). Suitable installation materials: - pressure-resistant (min. 10 bar) - heat-resistant (min. 100 °C). When using universal swivel cou- plings (bayonet couplings), only use versions with an additional securing ring to ensure safe seal- ing.

6.1 Setting the pilot pressure

Set the pilot pressure before initial operation. See

The device must be positioned on a horizontal, flat surface that is suitable for the device weight with water filling. To avoid vibrations, the device should not be bolted on but rather should be positioned on a resilient base. The place of installation should be well ventilated and protected against weather influences. Protect against frost - see section 8.3. For operation in garden ponds and swimming pools, the device must be installed in a flood-proof location and secured against fall- ing in. Additional statutory require- ments must be taken into consid- eration.

6.3 Connecting the suction line

Caution! The suction line must be installed such that no mechanical or twisting forces are exerted on the pump. Caution! Use an intake filter to protect the pump against sand and contamination. Caution! A check valve is absolutely neces- sary to prevent the water from draining when the pump is switched off. We recommend the installation of check valves at the intake opening of the suction hose and at the suction connection (12) of the pump. Depending on the model, a check valve may already be integrated (see section 13. Technical Specifications). Seal all screw-couplings with thread sealing tape. Leaks result in air intake and reduce or prevent the water intake. The suction line should have an inside diameter of at least 1" (25 mm); it must be kink- and vacuum- resistant. The suction line should be as short as possible because the longer the line length, the lower the conveying capacity. The suction line should rise uniformly towards the pump to prevent air inclusions. A sufficient water supply must be guaranteed and the end of the suction line should always be under water.

6.4 Connecting the discharge line

Caution! The discharge line must be installed such that no mechanical or twisting forces are exerted on the pump. Seal all screw-couplings with thread sealing tape to prevent water discharge. All components of the discharge line must be pres- sure-resistant and installed correctly. Danger! If non-pressure-resistant compo- nents are installed, or assembly is incorrect, the discharge line can burst during operation. Inju- ries are possible if highly pressurised fluids are ejected!

6.5 Connection to a pipe network

To reduce vibration and noises, the device should be connected with flexible hose lines to the pipe network.

6.6 Mains connection

Danger! Risk of electric shock! Never operate the device in a wet environment and only under the following conditions: - Connect only to an earthed outlet that is properly installed, earthed and tested. - Mains voltage, mains frequency and fuse protection must corre- spond to those stated in the 'Technical Specifications'. - The device must be supplied via a residual-current device (RCD) with a rated residual current of max. 30 mA. - The electrical connections must not be under water and must be located in a flood-proof area. The connections must be splash- proof for outdoor use. - Extension cables must have sufficient conductor cross sections. Unroll cable reels fully. - National installation specifica- tions must be observed.

6.7 Filling the pump and suction

Caution! In the case of a new connection, water loss or air intake, the pump must be filled with water. Operation of the pump without water filling will destroy it! - Unscrew water filling screw (13) including gasket. - Slowly pour in clean water until the pump is filled. - Screw in water filling screw (13) with gasket again. - Open the discharge line (open water tap or spray nozzle) so that air can escape during suction. - Switch on the device (see section 7.). - When water emerges evenly, the device is ready for operation. Note: The suction line does not need to be filled because the pump is self-priming. Depending on the length and diameter of the line, however, it may take some time until pressure is built up. To shorten the suction time: install a check valve at the intake opening of the suction hose and fill the suction line too. Caution! The pump and suction line must be connected and filled (see section 6.). Caution! The pump must not be allowed to run dry. There must always be sufficient conveying medium (water) available. If the pump is blocked by foreign bodies or the motor is overheated, a protective circuit shuts down the motor.

7.1 Explanation of operating elements

Devices with ON/OFF switch (see illustration A) Use the switch (1) to turn the device on/off. Devices with control panel (see illustration B) For HWA..., HWW...: Insert mains plug. The pump is ready for operation: The LED (3) lights up in blue (STANDBY). Switching on: To switch on, press the ON/OFF button (4) briefly. The pump motor starts to run and the LED (3) lights up in green. Dry-running protection: If the pump is unable to convey water after 20 seconds, the LED (3) starts to flash slowly in green. If the pump is unable to convey water after a further 100 seconds, the pump motor stops for 5 seconds (the LED (3) starts to flash quickly in green), and tries to convey water for a further 2 cycles. If the pump cannot still convey water, it stops and the LED (2) lights up in red (dry-running protec- tion). Check that the end of the suction line is under water. Check if leaks are causing air intake and thus preventing water intake. Proceed as described below to put the pump into operation once again: HWA..., HWW...: Press the button (4) and keep it pressed for 3 seconds (RESET). P 6000 Inox: Disconnect the mains plug and insert once again. When the pump is able to convey water, the LED (3) lights up in green and remains lit. Switching off: To switch off, press the ON/OFF button (4) briefly. Pump shut-down when the discharge line is closed: If the discharge line is closed when the pump is running, (close water tap or spray nozzle), the pump must switch off automatically. Otherwise, overheating or damage can occur or there may be a risk of scalding due to the heated water. The electronics check at regular intervals whether water is flowing through the pump. HWW..., HWA...: If there is no water flow detected, the LED (3) flashes in green for 40/70 seconds. The pump motor then switches off and the LED (3) lights up in blue (STANDBY). P 6000 Inox: If there is no water flow detected, the LED (3) flashes in green slowly for 20 seconds and then quickly for a further 5 seconds. The pump motor then switches off and the LED (3) lights up in red. To put the pump into operation once again: Disconnect the mains plug and insert once again. Safety mechanism for insufficient flow volume: If the flow volume is insufficient (less than approx. 60 l/h, e.g. in the case of leaks), the pump switches on and off frequently. This can cause the pump to overheat or get damaged or the heated water may pose a scalding risk. If the pump tries to switch on/ off more than 6 times in 100 seconds, it is switched off for safety reasons and the LED (2) lights up in red. Eliminate the reason for this! To put the pump into operation once again: Disconnect the mains plug and insert once again.

7.2 Using the device

Pump (device designation P...) Functional principle: The device operates while it is switched on. Danger! P 4500 Inox: If the discharge line is closed, run the pump for a maximum of 5 minutes because otherwise overheating of the water in the pump can cause damage.

5. Check that water emerges!

6. When work is complete, turn off the device -

see section 7.1. Only for P 6000 Inox : A switch to "Mode A" is necessary if the pump is to be activated via an attachment unit (e.g. Hydromat (order no. 0903063238), timer). To do this, insert the mains plug and press the button (4) for more than 3 seconds. The LED (3) changes from green to blue. The pump can now be unplugged and connected to the attachment unit. To return to "normal mode", insert the mains plug and press the button (4) for more than 3 seconds. The LED (3) changes from blue to green.

6. Initial Operation

The pump can be switched on/off in "Mode A" using the button (4) also. Dry-running protection is also the same as in normal mode. Automatic domestic water system (device designation HWA...) Functional principle: The device switches on when the removal of water causes the water pressure to fall below the switch-on pressure; it switches off again when switch-off pressure is reached.

4. Open the discharge line (open water tap or

5. Check that water emerges! The device is now

ready for operation. Domestic water system (device designation HWW...) Functional principle: The device switches on when the removal of water causes the water pressure to fall below the switch-on pressure; it switches off again when switch-off pressure is reached. The pressure vessel contains a rubber bellows, which is under air pressure (pilot pressure) when deliv- ered; this permits the removal of small volumes of water without the pump starting up.

4. Open the discharge line (open water tap or
