Operating pressure Maximum: 6 bar. Intermittent operation Maximum 20 starts per hour. ph value SL1 and SLV pumps in permanent installations can be used for pumping liquids with a ph value between 4 and 10. Liquid temperature 0 C to +40 C. For short periods (maximum 15 minutes) a temperature of up to + 60 C is permissible (non-ex versions only). Explosion-proof pumps must never pump liquids with a temperature higher than +40 C. Density and viscosity of pumped liquid When pumping liquids with a density and/or a kinematic viscosity higher than that of water, use motors with correspondingly higher outputs. 9

3. Delivery and handling The pump may be transported and stored in a vertical or horizontal position. Make sure that it cannot roll or fall over. 3.1 Transportation All lifting equipment must be rated for the purpose and checked for damage before any attempts to lift the pump. The lifting equipment rating must under no circumstances be exceeded. The pump weight is stated on the pump nameplate. Always lift the pump by its lifting bracket or by means of a fork-lift truck if the pump is fixed on a pallet. Never lift the pump by means of the motor cable or the hose/pipe. The polyurethane-embedded plug prevents water from penetrating into the motor via the motor cable. 3.2 Storage During long periods of storage, the pump must be protected against moisture and heat. After a long period of storage, the pump should be inspected before it is put into operation. Make sure that the impeller can rotate freely. Pay special attention to the condition of the shaft seals and the cable entry. 10

6. Safety For safety reasons, all work in tanks must be supervised by a person outside the pump tank. Note Pump installation in tanks must be carried out by specially trained persons. Work in or near tanks must be carried out according to local regulations. Persons must not enter the installation area when the atmosphere is explosive. It must be possible to lock the mains switch in position 0. Type and requirements as specified in EN 60204-1, 5.3.2. The use of this product requires experience with and knowledge of the product. Persons with reduced physical, sensory or mental capabilities must not use this product, unless they are under supervision or have been instructed in the use of the product by a person responsible for their safety. Children must not use or play with this product. It is advisable to make all maintenance and service work when the pump is placed outside the tank. Tanks for submersible sewage and wastewater pumps may contain sewage or wastewater with toxic and/or disease-causing substances. Therefore, all persons involved must wear appropriate personal protective equipment and clothing, and all work on and near the pump must be carried out under strict observance of the hygiene regulations in force. Make sure that the lifting bracket is tightened before attempting to lift the pump. Tighten if necessary. Carelessness during lifting or transportation may cause injury to personnel or damage to the pump. 6.1 Potentially explosive environments Use explosion-proof pumps for applications in potentially explosive environments. SL1 and SLV pumps must under no circumstance pump combustible liquids. The classification of the installation site must be approved by the local firefighting authorities in each individual case. The explosion protection classification of the pumps is CE II 2 G, Ex d IIB T4 X. The classification of the installation site must be approved by the local fire-fighting authorities in each individual case. Special conditions for safe use of SL1 and SLV explosion-proof pumps: 1. Bolts used for replacement must be class A2-70 or better according to EN/ISO 3506-1. 2. The level of pumped liquid must be controlled by two stop level switches connected to the motor control circuit. The minimum level depends on the installation type and is specified in these installation and operating instructions. 3. Make sure the permanently attached cable is suitably mechanically protected and terminated in a suitable terminal board placed outside the potentially explosive area. 4. The thermal protection in the stator windings has a nominal cut-out temperature of 150 C guaranteeing the disconnection of the power supply; the resetting of the supply is manual. 14

7. Installation Caution Fit the extra nameplate supplied with the pump at the installation site or keep it in the cover of this booklet. All safety regulations must be observed at the installation site, e.g. the use of blowers for fresh-air supply to the tank. Prior to installation, check the oil level in the oil chamber. See section 10. Maintenance and service. The pumps are suitable for different installation types which are described in sections 7.1 Submerged installation on auto-coupling and 7.2 Free-standing submerged installation. All pump housings have a cast DN 65, PN 10 discharge flange. Note Caution Prior to installation, make sure the tank bottom is even. Before beginning the installation, switch off the power supply and lock the mains switch in position 0. Any external voltage connected to the pump must be switched off before working on the pump. The pumps are designed for intermittent operation. When completely submerged in the pumped liquid, the pumps can also operate continuously. See section 12. Technical data. Do not put your hands or any tool into the pump suction or discharge port after the pump has been connected to the power supply, unless the pump has been switched off by removing the fuses or switching off the mains switch. It must be ensured that the power supply cannot be accidentally switched on. We recommend to always use Grundfos accessories to avoid malfuncions due to incorrect installation. Only use the lifting bracket for lifting the pump. Do not use it to hold the pump when in operation. 7.1 Submerged installation on autocoupling Pumps for permanent installation can be installed on a stationary auto-coupling guide rail system. See fig. A, page 463. The auto-coupling system facilitates maintenance and service as the pump can easily be lifted out of the tank. Note Note Before beginning installation procedures, make sure that the atmosphere in the tank is not potentially explosive. Proceed as follows: 1. Drill mounting holes for the guide rail bracket on the inside of the tank and fasten the guide rail bracket provisionally with two screws. 2. Place the auto-coupling base unit on the bottom of the tank. Use a plumb line to establish the correct positioning. Fasten the auto coupling with expansion bolts. If the bottom of the tank is uneven, the auto-coupling base unit must be supported so that it is level when being fastened. 3. Assemble the discharge line in accordance with the generally accepted procedures and without exposing the line to distortion or tension. 4. Place the guide rails on the auto-coupling base unit and adjust the length of the rails accurately to the guide rail bracket at the top of the tank. 5. Unscrew the provisionally fastened guide rail bracket, fit it on top of the guide rails and finally fasten it firmly to the tank wall. Note Make sure that the pipework is installed without the use of undue force. No loads from the pipework weight must be carried by the pump. We recommend the use of loose flanges to ease the installation and to avoid pipe tension at flanges and bolts. Do not use elastic elements or bellows in the pipework; these elements should never be used as a means to align the pipework. The guide rails must not have any axial play as this would cause noise during pump operation. 6. Clean out debris from the tank before lowering the pump into the tank. 7. Fit the guide claw to the discharge port of the pump. 8. Slide the guide claw between the guide rails and lower the pump into the tank by means of a chain secured to the lifting bracket of the pump. When the pump reaches the auto-coupling base unit, the pump will automatically connect tightly. 15

9. Hang up the end of the chain on a suitable hook at the top of the tank and in such a way that the chain cannot come into contact with the pump housing. 10.Adjust the length of the motor cable by coiling it up on a relief fitting to ensure that the cable is not damaged during operation. Fasten the relief fitting to a suitable hook at the top of the tank. Make sure that the cables are not sharply bent or pinched. 11.Connect the motor cable and the monitoring cable, if any. Note 7.2 Free-standing submerged installation Pumps for free-standing submerged installation can stand freely on the bottom of the tank or the like. See fig. B, page 464. In order to facilitate service on the pump, fit a flexible union or coupling to the elbow on the discharge line for easy separation. If a hose is used, make sure that the hose does not buckle and that the inside diameter of the hose matches that of the pump discharge port. If a rigid pipe is used, fit the union or coupling, non-return valve and isolating valve in the order mentioned, when viewed from the pump. If the pump is installed in muddy conditions or on uneven ground, we recommend to support the pump on bricks or a similar support. Proceed as follows: 1. Fit a 90 elbow to the pump discharge port and connect the discharge pipe/hose. 2. Lower the pump into the liquid by means of a chain secured to the lifting bracket of the pump. We recommend to place the pump on a plane, solid foundation. Make sure that the pump is hanging from the chain and not the cable. 3. Hang up the end of the chain on a suitable hook at the top of the tank and in such a way that the chain cannot come into contact with the pump housing. 4. Adjust the length of the motor cable by coiling it up on a relief fitting to ensure that the cable is not damaged during operation. Fasten the relief fitting to a suitable hook. Make sure that the cables are not sharply bent or pinched. 5. Connect the motor cable and the monitoring cable, if any. Note The free end of the cable must not be submerged as water may penetrate through the cable into the motor. The free end of the cable must not be submerged as water may penetrate through the cable into the motor. 8. Electrical connection Connect the pump to an external mains switch which ensures all-pole disconnection with a contact separation according to EN 60204-1, 5.3.2. It must be possible to lock the mains switch in position 0. Type and requirements as specified in EN 60204-1, 5.3.2. The electrical connection must be carried out in accordance with local regulations. The pumps must be connected to a control box with a motor protection relay with IEC trip class 10 or 15. Pumps for hazardous locations must be connected to a control box with a motor protection relay with IEC trip class 10. Do not install Grundfos control boxes, pump controllers, Ex barriers and the free end of the power cable in potentially explosive environments. The explosion protection classification of the pump is CE II 2 G, Ex d IIB T4 X. The classification of the installation site must be approved by the local fire-fighting authorities in each individual case. On explosion-proof pumps, make sure that an external earth conductor is connected to the external earth terminal on the pump using a conductor with a secure cable clamp. Clean the surface of the external earth connection and mount the cable clamp. The cross section of the earth conductor must be at least 4 mm 2, e.g. type H07 V2-K (PVT 90 ) yellow/green. Make sure that the earth connection is protected against corrosion. Make sure that all protective equipment has been connected correctly. Float switches used in potentially explosive environments must be approved for this application. They must be connected to the Grundfos LC, LCD 108 pump controller via the intrinsically safe LC-Ex4 barrier to ensure a safe circuit. 16

Caution If the supply cable is damaged, it must be replaced by the manufacturer, its service agent or a similarly qualified person. Set the motor-protective circuit breaker to the rated current of the pump. The rated current is stated on the pump nameplate. If the pump has an Ex mark on the nameplate, make sure that the pump is connected in accordance with the instructions given in this booklet. The supply voltage and frequency are marked on the pump nameplate. The voltage tolerance must be within 10 %/+6 % of the rated voltage. Make sure that the motor is suitable for the power supply available at the installation site. All pumps are supplied with 10 m cable and a free cable end. The pump must be connected to one of these two controller types: a control box with motor-protective circuit breaker, such as Grundfos CU 100 control box a Grundfos LC, LCD 107, LC, LCD 108 or LC, LCD 110 pump controller. See fig. 4 or 5 and the installation and operating instructions for the selected control box or pump controller. Potentially explosive environments In potentially explosive environments you have two options: Use float switches made for Ex environment and a safety barrier in combination with either DC, DCD or LC, LCD 108. Use air bells in combination with LC, LCD 107. Before installation and the first start-up of the pump, check the condition of the cable visually to avoid short circuits. For more information about the function of the thermal switches, see 8.4 Thermal switches. 8.1 Wiring diagrams Fig. 4 Fig. 5 PE Wiring diagram for single-phase pumps Wiring diagram for three-phase pumps 8.2 CU 100 control box L 4 5 PE 1 2 3 6 1 N PE L1 L2 L3 T2 160 C 150 C The CU 100 control box incorporates a motorprotective circuit breaker and is available with level switch and cable.

Start and stop levels: The difference in level between start and stop can be adjusted by changing the free cable length. Long free cable = large difference in level Short free cable = small difference in level. Note Both the two following points must be observed. To prevent air intake and vibrations, install the stop level switch in such a way that the pump is stopped before the liquid level is lowered below the upper edge of the clamp on the pump. Install the start level switch in such a way that the pump is started at the required level; however, the pump must always be started before the liquid level reaches the bottom inlet pipe to the tank. The CU 100 control box must not be used for Ex applications. See section 8.3 Pump controllers. The pump must not run dry. An additional level switch must be installed to ensure that the pump is stopped in case the stop level switch is not operating. See fig. 6. The pump must be stopped when the liquid level reaches the upper edge of the clamp on the pump. Float switches used in potentially explosive environments must be approved for this application. They must be connected to the Grundfos DC, DCD or LC, LCD 108 pump controller via an intrinsically safe barrier to ensure a safe circuit. 8.3 Pump controllers The following LC and LCD pump controllers are available: LC controllers are for one-pump-installations and LCD controllers are for two-pump-installations. LC 107 and LCD 107 with air bells LC 108 and LCD 108 with float switches LC 110 and LCD 110 with electrodes. In the following description, "level switches" can be air bells, float switches or electrodes, depending on the pump controller selected. Controllers for single-phase pumps incorporate capacitors. The LC controller is fitted with two or three level switches: One for start and the other for stop of pump. The third level switch, which is optional, is for high-level alarm. The LCD controller is fitted with three or four level switches: One for common stop and two for start of the pumps. The fourth level switch, which is optional, is for high-level alarm. When installing the level switches, observe the following points: To prevent air intake and vibrations, install the stop level switch in such a way that the pump is stopped before the liquid level is lowered below the middle of the motor housing. Install the start level switch in such a way that the pump is started at the required level; however, the pump must always be started before the liquid level reaches the bottom inlet pipe to the tank. If installed, always install the high-level alarm switch about 10 cm above the start level switch; however, the alarm must always be given before the liquid level reaches the inlet pipe to the tank. For further information, see the installation and operating instructions for the pump controller selected. Fig. 6 Start and stop levels Alarm Start Stop Additional stop TM02 7430 2709 The pump must not run dry. An additional level switch must be installed to ensure that the pump is stopped in case the stop level switch is not operating. The pump must be stopped when the liquid level reaches the upper edge of the clamp on the pump. Float switches used in potentially explosive environments must be approved for this application. They must be connected to the Grundfos DC, DCD or LC, LCD 108 pump controller via an intrinsically safe barrier to ensure a safe circuit. 18

8.4 Thermal switches All pumps have two sets of thermal switches incorporated in the stator windings. Thermal switch, circuit 1 (T1-T3), breaks the circuit at a winding temperature of approx. 150 C. Note This thermal switch must be connected for all pumps. Thermal switch, circuit 2 (T1-T2), breaks the circuit at a winding temperature of approx. 170 C (threephase pumps) or 160 C (single-phase pumps). After thermal cutout, explosion-proof pumps must be restarted manually. The thermal switch (circuit 2) must be connected for manual restarting of these pumps. Maximum operating current of the thermal switches is 0.5 A at 500 VAC and cos ϕ 0.6. The switches must be able to break a coil in the supply circuit. In the case of standard pumps, both thermal switches can (when closing the circuit after cooling) generate automatic restarting of the pump via the controller. The separate motor-protective circuit breaker/control box must not be installed in potentially explosive environments. 8.5 Frequency converter operation For frequency converter operation please observe the following information. Requirements must be fulfilled. Recommendations ought to be fulfilled. Consequences should be considered. 8.5.1 Requirements The thermal protection of the motor must be connected. Peak voltage and du/dt must be in accordance with the table below. The values stated are maximum values supplied to motor terminals. The cable influence has not been taken into account. See data sheet for the frequency converter used regarding the actual values and cable influence on the peak voltage and du/dt. 8.5.2 Recommendations Before installing a frequency converter, calculate the lowest allowable frequency in the installation in order to avoid zero flow. Do not reduce the motor speed to less than 30 % of rated speed. Keep the flow velocity above 1 m/sec. Let the pump run at rated speed at least once a day in order to prevent sedimentation in the piping system. Do not exceed the frequency indicated on the nameplate. In this case there is risk of motor overload. Keep the motor cable as short as possible. The peak voltage will increase with the length of the motor cable. See data sheet for the frequency converter used. Use input and output filters on the frequency converter. See data sheet for the frequency converter used. Use screened motor cable if there is a risk that electrical noise can disturb other electrical equipment. See data sheet for the frequency converter used. 8.5.3 Consequences When operating the pump via a frequency converter, please be aware of these possible consequences: The locked-rotor torque will be lower. How much lower will depend on the frequency converter type. See the installation and operating instructions for the frequency converter used for information on the locked-rotor torque available.
