Frequently Asked Questions - Prisma 45 N ESPA

What to do if the motor does not start?

Check the power supply, fuse or circuit breaker. If the motor is locked, disassemble the pump and contact an approved technical service.

Why does the pump run but not provide pressure?

This may be due to a blocked foot valve, too high head, or air intake in the piping. Clean the valve or check the tightness of the fittings.

The motor is overheating, what to do?

Make sure the voltage matches the nameplate and that ventilation is sufficient. Insufficient flow or poor ventilation can also cause overheating.

How to prime the pump correctly?

Fill the pump body with water through the filling plug. If a foot valve strainer is installed, also fill the suction pipe. Never run the pump dry.

What type of water can be pumped with the Prisma 45 N?

This pump is designed for clean water, free of suspended solids, with a maximum temperature of 40 °C.

How to connect the pump electrically?

Use an omnipolar switch with a contact opening of at least 3 mm and a 30 mA residual current circuit breaker. Connection must be carried out by an approved installer.

What to do in case of frost?

Drain the pipes and pump to prevent ice formation. If the pump remains inactive for a long time, store it in a dry, ventilated place.

How to maintain the pump?

Under normal conditions, no special maintenance is required. Clean the outside with a damp cloth without aggressive products. In case of failure, call an approved technical service.

The pump stops and restarts by itself (cycling), why?

This is often due to motor overheating (thermal protection) caused by incorrect voltage, poor ventilation, or a worn impeller. Check these points.

Where to find spare parts for the Prisma 45 N?

Spare parts are available from official ESPA technical services. Visit www.espa.com to find the nearest approved repairer.

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

DANGER

Warns that failure to observe the pre cautions involves a risk of electric shock.

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 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.

The ASPRI models are manufactured to include a recirculation system with automatic valve achieving suction lifts of up to nine meters. By using a foot valve on the suction pipe the pump will rapidly self-prime when operated.

These pumps are designed to operate with clean water, free from particles in suspension and with a maximum temperature of 40^ C.

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.

2. HANDLING

The pumps are supplied suitably packaged to prevent damage in transit. Before unpacking, check that the packaging has not been damaged or deformed,

Lift and handle the product with care and with the right tools.

3. INSTALLATION

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. Ensure that the pump mount rests squarely on the base before fixing.

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 recommended to fit a check valve to prevent accidental draining down of the system.

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 ( fn = 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 performed by a qualified installer according to the needs of the facility and following the regulations in force in each country.

Pump models 15 and 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 electrical 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.

4. STARTING

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 reversed.

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.

In the ASPRI models, the self-priming time can take several minutes.

5. MAINTENANCE

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.
