ATTENTION! Observe the total weight of the Sulzer units and their attached components (see nameplate for weight of base unit). The duplicate nameplate provided must always be located and visible close to where the unit is installed (e.g. at the terminal boxes / control panel where the cables are connected). NOTE! Lifting equipment must be used if the total unit weight and attached accessories exceeds local manual lifting safety regulations. The total weight of the unit and accessories must be observed when specifying the safe working load of any lifting equipment! The lifting equipment, e.g. crane and chains, must have adequate lifting capacity. The hoist must be adequately dimensioned for the total weight of the Sulzer units (including lifting chains or steel ropes, and all accessories which may be attached). The end user assumes sole responsibility that lifting equipment is certified, in good condition, and inspected regularly by a competent person at intervals in accordance with local regulations. Worn or damaged lifting equipment must not be used and must be properly disposed of. Lifting equipment must also comply with the local safety rules and regulations. NOTE! The guidelines for the safe use of chains, ropes and shackles supplied by Sulzer are outlined in the Lifting Equipment manual provided with the items and must be fully adhered to.

These starting and operating instructions are applicable to electric submersible pumps specified on the cover. The pumps are intended for pumping water that may contain abrasive particles. The pump must not be used in an explosive or flammable environments or for pumping flammable liquids. The pumps conform to the EU machine directive. The manufacturer guarantees that a new pump will not emit airborne noise in excess of 70 dB(A) during normal operation, when either fully or partially submerged. The pump must not be run if it has been partially dismantled. Earth leakage detector (RCD Residual-current device) is recommended to be used when a person come in contact with either the pump or the pumped media. Special regulations apply for permanent installation of pumps in swimming pools.
Limitations Immersion depth: up to 20 m/65 ft (J 5: 9.5 m/31 ft). Liquid temperature: up to 40°C (105°F). Motor Single-phase AC motor or 3-phase squirrel-cage induction motor for 50 or 60 Hz. Level control Some pumps can be equipped with float switch for automatic level control. Motor protection Single-phase pumps have a built in start- and run-capacitor. For built in motor protection, the thermal contacts in the motor are fitted to disconnect the power at high temperature. The thermal contacts can as alternative be connected to an external motor protection. Electric cable H07RN8-F, S1BN8-F or equivalent cable. If the cable is longer than 20 m, the voltage drop must be taken into account. Note that the pumps can be supplied with different cables and for different connection methods.
The pump can be transported and stored either vertically or horizontally. Make sure that it is secured and cannot roll. The pump must always rest on a firm surface so that it will not overturn. This applies to all handling, transport, testing and installation. Always lift the pump by the lifting handle - never by the motor cable or hose. NOTE! Always protect the cable end so that no moisture will penetrate into the cable. Water could otherwise seep into the terminal compartment or into the motor through the cable. If the pump is stored for a long period of time, protect it against dirt and heat. After a longer period of storage, the pump must be inspected and the impeller must be rotated by hand before the pump is taken into operation. Check the seals and cable entry particularly carefully.
Safety measures In order to reduce the risk of accidents during service and installation work, take extreme care and bear in mind the risk of electrical accidents. The lifting tackle must always be designed to suit the pump weight. See under the heading ”Product description”. Pump installation Arrange the cable run so that the cables will not be kinked or nipped. Connect the cable. Connect the delivery piping. Hoses, pipes and valves must be selected to suit the pump delivery head. Place the pump on a firm surface which will prevent it from overturning or burrowing down. The pump can also be suspended by the lifting handle slightly above the bottom.
The pump must be connected to terminals or starting equipment installed at a level at which it cannot be flooded. All electrical equipment must always be earthed (grounded). This applies both to the pump and to any monitoring equipment. The electrical installation must conform to national and local regulations. Check that the mains voltage, frequency, starting equipment and method of starting agree with the particulars stamped on the motor rating plate. N.B. A pump designed for 400V50Hz, 460V60Hz can be used in the 380-415V50Hz, 440-460V60Hz range. A pump designed for 230 volt can be used in the 220 -245 volt range. Connection of stator and motor conductors If the pump is not fitted with a connector, connect it in accordance with valid wiring diagram. Wiring diagrams are included in the workshop manual. Cable marking on pump cables: L1, L2, L3 = phase marking at D.O.L start / U1, V1, W1, U2, V2, W2 = stator marking at star-delta start / F0, F1, F3, F4 = thermal sensor marking / D1, D2 = leakage sensor marking, must be connected to external relay / GC = ground check marking The electrical installation shall be inspected by an authorized electrician.
Before starting: Check the direction of rotation of the pump (see figure). At the instant of starting, the pump will jerk anti-clock-wise when viewed from above. If the direction of rotation is incorrect, transpose two phases. Starting jerk The starting jerk may be violent. Don’t hold the pump handle when checking the direction of rotation. Make sure that the pump is firmly supported and cannot rotate. Reversal of the direction of rotation on a plug that has no phase transposing device may be done only by an authorized person. If the built-in motor protection has tripped, the pump will stop but will restart automatically when it has cooled down.
Before any work is started, check that the pump is isolated from the power supply and cannot be energized. Regular inspection and preventive maintenance will ensure more reliable operation. The pump should be inspected every six months, but more frequently if the operating conditions are difficult. For a complete overhaul of the pump, please get in touch with an authorized Sulzer work-shop or your Sulzer dealer. If a cable is damaged, it must always be replaced. A worn impeller often has sharp edges. Take care not to cut yourself on them. In the event of inward leakage, the oil housing may be pressurized. When removing the oil plug, hold a piece of cloth over it to prevent oil from splashing. J 205 - 604 Two overhead cranes must be used to lay the pump or motor section on its side safely. When the pump or motor section has been laid on its side, always secure it with wedges from both sides to prevent it from rolling away. End-of-life units can be returned to Sulzer or recycled in accordance with local regulations. The manufacturer reserves the right to change the design and specifications.
