USER MANUAL MultiDrain UV3 SF JUNG

• Installation of a water level dependent (under circumstan- ces, mains-independent) alarm system, so that the alarm can be heard before damage occurs.

• Inspection of the collecting tank/chamber for tightness up to the top edge before – or at the latest, during – installation or operation of the product.

• Installation of backow protection for drainage units that can be damaged by wastewater leakage upon product failure.

• Installation of a further product that can compensate in case of failure of the other product (e.g. duplex unit).

• Installation of an emergency power generator. As these precautions serve to prevent or minimise conse- quential damage upon product failure, they are to be strictly observed as the manufacturer’s guideline – in line with the standard DIN EN specications as state of the art – when using the product (Higher Regional Court Frankfurt/Main, Ref.: 2 U 205/11, 06/15/2012). SAFETY INSTRUCTIONS This instruction manual contains essential information that must be observed during installation, operation and servic- ing. It is therefore important that the installer and the respon- sible technician/operator read this instruction manual before the equipment is installed and put into operation. The manual must always be available at the location where the pump or the plant is installed. Failure to observe the safety instructions can lead to the loss of all indemnity. In this instruction manual, safety information is distinctly la- belled with particular symbols. Disregarding this information can be dangerous. General danger to people Warning of electrical voltage NOTICE! NOTICE! Danger to equipment and operation Qualication and training of personnel All personnel involved with the operation, servicing, inspection and installation of the equipment must be suitably qualied for this work and must have studied the instruction manual in depth to ensure that they are suciently conversant with its contents. The supervision, competence and areas of responsi- bility of the personnel must be precisely regulated by the ope- rator. If the personnel do not have the necessary skills, they must be instructed and trained accordingly. Safety-conscious working The safety instructions in this instruction manual, the existing national regulations regarding accident prevention, and any internal working, operating and safety regulations must be ad- hered to. Safety instructions for the operator/user All legal regulations, local directives and safety regulations must be adhered to. The possibility of danger due to electrical energy must be pre- vented. Leakages of dangerous (e.g. explosive, toxic, hot) substances must be discharged such that no danger to people or the envi- ronment occurs. Legal regulations must be observed. Safety instructions for installation, inspection and mainte- nance works As a basic principle, works may only be carried out to the equip- ment when it is shut down. Pumps or plant that convey harmful substances must be decontaminated. All safety and protection components must be re-tted and/or made operational immediately after the works have been com- pleted. Their effectiveness must be checked before restarting, taking into account the current regulations and stipulations. Unauthorised modications, manufacture of spare parts The equipment may only be modied or altered in agreement with the manufacturer. The use of original spare parts and accessories approved by the manufacturer is important for safety reasons. The use of other parts can result in liability for consequential damage being rescinded. Unauthorised operating methods The operational safety of the supplied equipment is only guar- anteed if the equipment is used for its intended purpose. The limiting values given in the "Technical Data" section may not be exceeded under any circumstances. Instructions regarding accident prevention Before commencing servicing or maintenance works, cordon off the working area and check that the lifting gear is in perfect condition. Never work alone. Always wear a hard hat, safety glasses and safety shoes and, if necessary, a suitable safety belt. Before carrying out welding works or using electrical devices, check to ensure there is no danger of explosion. People working in wastewater systems must be vaccinated against the pathogens that may be found there. For the sake of your health, be sure to pay meticulous attention to cleanliness wherever you are working. Make sure that there are no toxic gases in the working area. Observe the health and safety at work regulations and make sure that a rst-aid kit is to hand. In some cases, the pump and the pumping medium may be hot and could cause burns.7 ENGLISH For installations in areas subject to explosion hazards, special regulations apply! APPLICATION WARNING! The pump must only be connected to sockets that have been installed properly in accordance with the regulations and are protected with at least 10 A (slow) and RCD-safety switches (30mA). DANGER! The pump must never be used when a person is in the water. Submersible pumps from the UV 3 series are suitable for pumping domestic waste water without stones. This includes also water from household dishwashers and household wash- ing machines. NOTICE! In outdoor applications, only pumps with at least a 10-metre mains cable must be used. When using the pumps, the relevant national laws, regulations and stipulations must be adhered to, for example:

• Domestic contaminated and waste water (e.g. EN 12056 in Europe)

• Installation of low voltage systems (e.g. VDE 0100 in Germa- ny) For non-standard utilization conditions, further regulations must be observed (e.g. VDE 0100 in Germany, part 701: ba- throoms and shower rooms; part 702: swimming pools and fountains and part 737: outdoor use). Temperatures The pumped medium must have a temperature of max 35 °C. For a short time 70 °C are permissible (S2: 10 min, S3: 40%). The submersible pump is frost-resistant down to -20 °C when stored in dry conditions. When installed, however, it must not be allowed to freeze in the water. Transport The pump must always be lifted by the handle and never by the power supply cable! The pump should only be lowered into deeper chambers or pits using a rope or chain. ELECTRICAL CONNECTION NOTICE! Only qualied electricians may carry out electrical works to the pump or the controls. WARNING! Before carrying out any works: disconnect the pump and the controls from the mains and take steps to ensure that no one else can reconnect them to the power supply. The relevant standards (such as EN standards), country-spe- cic regulations (such as VDE in Germany), and the regulations of the local power supply companies must be observed. NOTICE! Never put the mains plug or a free lead end in water! If water gets into the plug, this can cause malfunctions and da- mage. Observe the operating voltage (see the type plate)! The pump is provided with a winding thermostat. In case of unacceptably high temperatures it switches off the pump to protect it against possible damage. Unacceptably high tem- peratures may result e.g. from dry running or mechanical or electrical overload. CAUTION! The pump is switched on again automatically after cooling down - risk of injury! For this reason, always disconnect the device from the mains before remedying the fault! In order to do this, unplug from the mains supply or remove the pre-fuses of the pump controls! INSTALLATION The pump must be installed as shown in the examples. For in- stallations in accordance with EN 12056-4, the pressure pipe must be laid in a loop above the local backow level and pro- tected with a backow prevention valve in accordance with EN 12050-4. A correspondingly larger diameter pipe should be used for longer pressure pipelines to avoid pipe friction losses. With any pump that has no automatic switching, the switch-on and switch-off heights can be set variably with a separate level control. Our ready to connect level controls can be installed without specic electrotechnical skills. NOTICE! The oats of the level controller and alarm system are installed so that they are freely movable but not under the inlet. Please observe the minimum distances. The controls may only be installed in a dry and well ventilated room! The pump housing is automati- cally vented. If this is not desired, the ventilation opening can be closed, e.g. for mobile operation. NOTICE! If the pump is malfunctioning, part of the contents of the oil reservoir could escape into the pumping medium. Flushing device The pump can keep the intake section at the bottom of the chamber clear of deposits to a large extent if you carry out a small modication: Remove the strainer basket, unscrew the three red closing caps and replace the strainer basket. This re- duces the performance of the pump only insignicantly.8 ENGLISH Low level pumping Flooded surfaces can be drained down to a residual water level of a few mm without using any special accessories. To do so, the foot strainer must be levered off with a screwdriver. In the case of pumps with an attached control, the oat switch must be locked in the ON position. It is not possible therefore in low level pumping to operate the pump in switching mode. To make the pump operate, the drainage hose must be emptied before each pumping run and there must be a minimum water level of 40 mm available

CAUTION! For safety reasons, mobile operation is only allowed with a foot strainer. If a hose is used as a pressure line, care must be taken to en- sure that for every pumping operation the hose is completely empty before the pump is submersed. Any residual liquid would obstruct the ventilation of the pump housing and therefore also hinder the pumping operation. For the same reason, the pump would not operate if it was switched on before being sub- mersed. CLEANING WARNING! Before carrying out any works: disconnect the pump and the controls from the mains and take steps to ensure that no one else can reconnect them to the power supply. WARNING! Check the mains cable for signs of mechanical and chemical damage. Damaged or kinked cables must be replaced by the manufacturer. NOTICE! If the water contains high levels of iron or lime, insuf- cient cleaning can result in irreparable damage to the seal and thus also to the pump motor in the long term. Consequently, the pump must be cleaned at regular intervals according to the hardness of the water. Tightening torque M
