1. GENERAL INFORMATION

Please observe the following instructions to achieve the best pump performance possible and a trouble free installation. Read these instructions before installing the pump. Save them for future reference. The DRAINEX models are used for the drainage of sewage water with particles in suspension, septic tanks, etc. Passage of particles in the DRAINEX 400/500 models = 40mm (MAX) and in the DRAINEX 600 models = 65mm (MAX). The maximum water temperature is 40°C. All pumps have been manufactured in top quality material, submitted to strict hydraulic and electric controls. Correct pump operation is assured providing the instructions on electrical connection, installation and use are strictly adhered to. Failure to adhere to the instructions can result in premature failure of the pump and voiding of the warranty. The pump cannot be used in a swimming-pool while there are people bathing. Do not put your hand or any object into the suction or discharge mouth, since the rotating impeller could cause serious injury or damage.

- Equipment to transfer water containing suspended particles. - Pumps suitable for extracting drainage and waste water; with filter for solids measuring 40mm and 65 mm.

The pump must only be installed in pits by qualified personnel in strict compliance with health and safety regulations in force. Pit work must be carried out in accordance with local regulations.

The pumps are supplied suitably packaged to pre- vent damage in transit. Before unpacking, check that the packaging has not been damaged or de-formed, Lift and handle the product with care and with the right tools.

5.1. Fixing and transport - Transportable option - Stationary option In both cases, the necessary accessories can be supplied separately with their assembly instruct- ions. For the transportable option, the following are supplied: a chain, stainless steel bases, discharge elbow and screws to fix the latter. For the stationary option, the following are supplied: a pump fixing accessory, a stationary accessory, a base for two 1” tubes, a joint and all necessary nuts and bolts. See (Fig. 3) Always lift the pump using the handle. The pump must always be totally submerged which will provide it with the necessary cooling. Ensure there is enough space for the free operation of the float switch (fig.3). The pump must never be supported by the electric cable or the discharge line (fig.3).12

5.2. Discharge pipe assembly In cases in which the discharge run is lengthy or sinuous, we recommend using lines with a larger diameter than the discharge mouth, to avoid head loss due to friction as much as possible and to obtain the best hydraulic performance possible. Install a check valve to the outlet of the pump and you will prevent pipe from emptying each time pump stops. The check valve must permit the passage of solids. Ensure that the pipe is not bent and that is correctly secured to the outlet connection because, in addition to preventing the desired flow, proper pump operation will be hindered. 5.3. Electrical connection The electrical installation must have an effective earth and comply with the national regulations in force. The protection of the system will be based on a differential switch (Δfn = 30mA) in addition to a multi-pole isolator with a minimum 3 mm contact openings, Pumps assembled with a starting control box or fitted with a capacitor are supplied ready for operation. In the case of three-phase pumps the user must provide the protection system. All pumps must be connected to a control panel fitted with a motor protector. ESPA control panels are built in. The panel comes with the operating instructions and technical information. 5.4. Pre-start checks The fitter must use a liquid level detection system to ensure that the pump remains submerged at all times. Pumps are supplied with thermal protectors in their windings. The latter must be connected to a protective switch so that the pump is disconnected before the winding reaches the maximum permitted temperature. Regulations do not permit automatic reconnection, so the control panel must also be equipped with a system to prevent automatic resetting. ESPA control panels are equipped with all the safety devices mentioned. See connections diagram (Fig. 2). THIS PUMP MUST NEVER BE DRY RUN. 5.5. Checks prior to initial start-up ATTENTION. Check that the mains voltage and frequency coincide with those shown on the nameplate. The pump must work in a fully submerged position to achieve optimal cooling. See (Fig. 4)

If there is a line valve, open it completely. Connect the electrical panel plug into a socket. If there is an appropriate level of water, the motor will immediately start up. Check that the absorbed current is the same as marked on the name plate. If the motor does not start or no water flows at the end of the line, try to find the anomaly using the troubleshooting guide in point 8. In the case of three-phase pumps check that the turning direction corresponds to the direction marked by the arrow situated in the suction cone. (fig. 4) Contact with the rotating impeller may cause serious injury.

7.1. General indications Disconnect the pump from the mains before performing any operation whatsoever. Under normal conditions these pumps require no special or planned maintenance. During frosty periods, remember to drain the line. If the pump is not going to be operated for a long period of time, it is recommended to remove the tank, clean it and store it in a dry, well ventilated place. To unclog or clean the impeller, it is only necessary to raise the suction cone. To do this, unscrew the screws that fasten the legs. The cover assembly must come off as a whole (fig.4). ATTENTION: In the event of faults or damage occurring to the pump, repairs should only be carried out by an authorised service agent. The Official Technical Services list is in www.espa.com. 7.2. Maintenance / inspection Maintenance must be carried out exclusively by a specialist. Annual checks: Check the power consumption, comparing it to the plate showing the characteristics of the pump. Bearings and lubrication: The bearings are supplied greased. They do not require subsequent lubrication. To ensure that the bearings work properly, check whether the axis produces noise or does not rotate smoothly. Wire inlet and suspension chain: Visually check that the wire inlet is sealed and that the wire is not bent or pinched. Check that the chain is secured properly and that

Cleaning the runner: To unblock or clean the runner, you only need to lift the suction base. To do so, loosen the fixing screws (as shown in (Fig. 4)). Changing the oil: The oil that lubricates the locks while the pump operates under normal conditions should be changed after 3000 h of operation or once a year. To empty it, dismantle the runner and loosen the T screw shown in (Fig. 4); and/or remove the lock. Remember that once the rotating part of the lock has been loosened, the oil may leak between the friction areas. To aid extraction of the runner, once you have removed the fixing screw you can screw in a M10 screw in the thread in the centre of the runner fitted for this purpose. The oil used is a white oil of mineral origin with medicinal quality. The quantity is 0.7 l. When changing the oil, use one with similar characteristics that fulfils regional regulations. If you dismantle the mechanical locks, you are advised to replace them and change the oil.
