Damage prevention and safety instructions (See figure 4)

Warning! Observe limitations of use.

The name plate voltage must be the same as the mains voltage.

Connect the pump to the mains via an omnipolar switch with at least a 3 mm opening between contacts. Install a high-sensitivity differential switch (0.03A) as extra protection against lethal electric shocks.

If the supply cord is damaged, it must be replaced by an A.T.S.

Connect the pump to the ground.

Use pump only within performance limits indicated on the name plate.

Remember to prime pump.

Check for motor self-ventilation.

This apparatus may be used by children 8 years or older and persons with reduced physical, sensory or mental capacities, or lacking experience and knowledge, if they are supervised or receive adequate training on the safe use of the apparatus and understand the dangers. Children should not be allowed to play with the apparatus. Children should not perform the ordinary cleaning and maintenance tasks without supervision.

Be careful with hazardous liquids and environments.

Caution! Look out for accidental leaks. Do not expose pump to bad weather.

Caution! Avoid icing. Cut out power supply before servicing pump.11

Safety precautions This symbol together with one of the following words “Danger” or “Warning” indicates the risk level deriving from failure to observe the prescribed safety precautions: DANGER risk of electric shock Warns that failure to observe the pre cautions involves a risk of electric shock. DANGER Warns that failure to observe the pre cautions involves a risk of damage to persons and/or things. WARNING Warns that failure to observe the pre cautions involves the risk of damaging the pump and/or the facility

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. These are vertical multistage centrifugal pumps having more than one impeller assembled in-line. The same flow passes through each impeller but the pressure increases each time, i.e. more impellers, more pressure. These pumps are designed to operate with clean water, free from particles in suspension and with a maximum temperature of 40 ºC. 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. Minimum efficiency index With the application of the European Regulation 547/2012, the minimum efficiency index after 01/01/2015 must be MEI ≥ 0.40. The reference value for the most efficient hydraulic pumps is rated at MEI ≥ 0.70. The performance curves and efficiency charac- teristics can be checked on the technical cata- logues and on www.espa.com. The operation of this hydraulic pump with variable operating points can be cheaper and more efficient when controlled with, for example, a speed regula- tion control that adjusts the pump's operation to the system performance. The efficiency reference criteria can be found on the following link: http://global.espa.com/doc-descarrega-1/fingerprints.pdf

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.

These pumps are designed for indoor use. Make sure that pump is never submerged and that it rests in a dry and well aired room. 3.1. Fixing The pump should be installed on a solid, horizontal base, secured by screws or bolts and using the existing holes in the mount. 3.2. Suction pipe assembly The suction pipe, if longer than 7 meters, must be of the same or greater diameter than the pump inlet and installed in an upward inclination to prevent trapped air pockets forming. If the pump is required to perform a suction lift, to avoid unnecessary losses of head on the discharge side, the pump should be installed as close as possible to the water. The end of the suction pipe must always remain at least 30 cm below the water level. (Fig.3) 3.3. Discharge pipe assembly It is recommended to use pipes with a diameter equal or greater than the pump outlet. This will reduce loss of head caused by friction in longer pipe runs. Pipework must be supported and their weight must not rest on the pump. If a foot valve has not been installed it is recom- mended to fit a check valve to prevent accidental draining down of the system.12

3.4. Electrical connection The electrical installation must have a multi- pole isolator with minimum 3 mm contact openings, The protection of the system will be based on a differential switch (Δfn = 30 mA) The power cable must correspond at least to the type H05 RN-F (according to 60245 IEC 57) and having terminals. The connection and its dimensioning must be per- formed by a qualified installer according to the needs of the facility and following the regulations in force in each country. Pump models 25: Single-phase motors have thermal protection. The rest of the pump models with single phase motor and all three phase motor pumps do not incorporate this protection. They must be connected to a motor- protective circuit breaker that can be adjusted manually. Set the circuit breaker according to the current given in the rating plate plus 10%. Follow instructions given on fig.1 for correct electri- cal connection. 3.5. Pre-start checks Ensure the voltage and frequency of the supply corresponds to the values indicated on the electrical data label. Ensure that the pump shaft is rotating freely. Fill the pump body with water through the self- priming plug opening. If a foot valve has been installed, also fill the suction pipe. Check all joints and connections for leaks. THIS PUMP MUST NEVER BE DRY RUN.

Ensure all valves in the pipework are open. Connect power supply. There will be a delay before water appears at the end of the discharge pipe. Viewings from the fan ensure that the rotation of the motor is clockwise. On three phase pumps the motor may rotate anticlockwise. If this is happening, the flow will be lower than expected. To rectify this situation the two supply phases need to be re- versed. Ensure that the absorbed current is the same or lower than the maximum shown on the name plate. Adjust the thermal relay if is necessary. If the pump fails to operate refer to the possible faults, causes and solutions list for assistance.

Under normal conditions these pumps require no special or planned maintenance. Clean the pump with a damp cloth without using harsh products. If the pump is not to be operated for a long period it is recommended to remove it from the installation, drain down and store in a dry, well ventilated place. 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.

6. DISPOSING OF THE PRODUCT

When the pump is eventually disposed of, please note that it contains no toxic or polluting material. All main components are material identified to allow selective disposal. This product or parts of it must be disposed of in an environmentally sound way, use the waste collection service. If this is not possible, contact the nearest ESPA service workshop.
